Safety

At every ETPC sanctioned event, safety is the name of the game. The sport of truck and tractor pulling has more brute horsepower than any other motorsport in the world.

With machinery this powerful, safety aspects cannot be overemphasized. There are many different types of safety equipment required, and this equipment will appear in many different areas of the vehicles. During a pull, safety is always in the front of everyone’s mind. The end of the track must be kept open at all times. The ETPC as well as every one of its member organizations will refuse to operate any pull at which a safety hazard is posed to any person.

Safety is everybody’s responsibility.

The promoter, pullers, spectators, and ETPC officials must work together to ensure the safety of all persons involved.

2009 1-1

Warranty disclaimer

The rules in this book are intended as guidelines for the sport of truck and tractor pulling, and the rules relating to the safety of the equipment are the responsibility of each driver who participates in the sport of truck and tractor pulling under these rules.

No expressed or implied warranty of safety is intended nor may be inferred from the publication of these rules, nor the compliance therewith. Nothing herein should be construed as a guarantee against injury or death to participants, bystanders or spectators.

Specifications and rules set forth in this rule book are based upon the recommendations of the WPI/NTPA.

Notice

Competitors are reminded and encouraged to contact the board of their organisation should they plan to build a competition vehicle employing new or unique processes or techniques; or are seeking to alter, change or modify existing competition vehicles, where such processes, techniques, or modifications could raise questions of legality in items of the rules regarding construction and/or safety.

B. COMPETITION RULES

A.

Eligibility of contestants

1.

All contestants participating in any truck and tractor pulling contest sanctioned by an

ETPC member must have a current competition membership. Contestants must be 18 years of age, or at least 16 years of age with a parent’s or a guardian’s written consent.

2.

No driver, tractor nor any combination thereof shall participate or exhibit in a pull or pull in front of a sledge not sanctioned by ETPC or by affiliated member.

The driver, all team-members, the vehicle and all parts of the vehicle are disqualified for one year and ten days from this years infraction at all sanctioned ETPC or affiliated members pulls.

The one year and ten days disqualification starts from the last violation day. In case the vehicle is to be sold, the disqualification must be mentioned to the new owner.

B. Vehicle registration

1.

Registration means identifying your vehicle with a registration number for points calculation. All vehicles must be registered before competing.

2.

The ETPC or affiliated member registration number must appear in a visible area of the vehicle.

3.

A vehicle owner may sell the vehicle including the registration number and accumulated points. If points are sold with the vehicle, all points for all classes must be sold.

4.

A puller can start competing with a new vehicle during a pulling season and keep his previous points from the season in question on condition that he uses the same name and registration number as with his old vehicle, and his old vehicle is not run anymore on that name and number.

5.

On all above-mentioned changes during the pulling year, to be calculated from the 1st of

January, your organization board must be notified in writing after sale and before the vehicle is registered for the next pull.

2009 1-2

C. Entry procedures

1.

Each vehicle may enter at two classes, but only once at each class. A vehicle must compete in a class at that individual event before it can receive points or starting money.

2.

A puller receives no starting money or points unless there has been made a measurable pull in a class.

3.

No mixing of classes.

4.

Classes in a given session will be run in that session, but not necessarily in the scheduled order.

5.

Once a puller has scratched from a class, he may not re-enter.

6.

If a puller’s vehicle breaks in a previous class and cannot make the pull order in the next class or session, the competitor may ask the Track Official for extra time. It is at the

Track Official’s discretion to allow the puller to drop positions.

D. Weight classes, Weighing and Drawbar measuring procedure

1.

On each location there will be a designated area, set up by the track officials, as a tech area, where all vehicles will be routinely teched, the same applies for weighing and drawbar measuring.

2.

The weight-bridge must be ETPC approved and big enough to weigh the entire tractor in at one time.

3.

All official weights include driver, vehicle with oil, water, fuel, and safety equipment, ready to compete. All drivers must weigh in with the pulling vehicle when it is officially weighed.

No vehicles will be allowed past weight-bridge that exceed class weight. No adding fuel or weights unless reweighed. Weighing out is at the discretion of the track officials.

4.

All drawbars need to be measured on three to five vehicles prior to hooking. After that time the drawbar can not be altered. A maximum of 100 kg (modifieds<950kg 30 kg) of weight may be moved in either direction.

No air pressure to be altered in tires after drawbar is measured.

5.

Should a puller move more than 100 kg ( modifieds<950kg 30 kg) of weight forward from the rear of the tractor, the drawbar can be remeasured before pulling at the discretion of the track officials.

6.

Drawbar can be remeasured after pull at the discretion of the track officials.

The use of additives containing oxygen, such as nitro methane, propylene oxide, dioaxane, MTBE, alcohol or nitrous oxide, are strictly prohibited. These additives, and others of the oxygen-bearing family, will significantly change the dielectric constant value of any diesel fuel. Diesel fuel with dielectric constant values that fall outside the ETPCstandards will not be allowed for use in ETPC competition.

2.

ETPC officials or officials from affiliated organisations can check fuel at any time during any event.

2009 2-20

Chapter 10:

OPERATION OF CONTEST

A. General rules

1.

Pulling vehicles must be operated in a safe manner at all times within the confines of the track, pits and staging areas. Officials have the right to stop and disqualify any vehicle if it is not being operated in such a manner as would be considered safe.

2.

Driver must remain seated while one or more engines of his vehicle are running. Leaving the seat is only allowed when all engines have completely stopped running. He must remain seated during the pull and must have complete control of the vehicle at all times.

3.

Only the driver will be allowed on a vehicle when it is being towed or driven, NO riders in or on any vehicle, in pit, track or adjacent areas.

4.

The driver and two helpers (one (1) at the start and one (1) helper at the end of the track) will be allowed to the track. Running with the tractor under green flag along trackside is forbidden. As track will be defined an area which includes the track and ten meters of space around the track. Violation of this rule will cause a disqualification of that pull.

For a driver with one (1) helper the rule is as follows:

The driver and one (1) helper will be allowed to the track. After assisting the driver at the starting line, the helper takes a position close to the public fence. Running with the tractor under green flag along trackside is forbidden. After the tractor has come to a standstill the helper can assist the driver. Violation of this rule will cause a disqualification of that pull.

5.

Any driver or any of his crew incapacitated due to an intoxicating agent, and/or drugs, his/her pulling vehicle will not compete for the duration of the pull. Further, any puller or pit crew member found around the track area with intoxicant will forfeit winnings and points from that event or his/her pulling vehicle will be banned from the next sanctioned event he/she appears at to compete.

6.

Unsportsmanlike conduct including abusive language and/or physical action toward event official, fellow competitor, or spectator and/or deliberate delay of event, will be just cause for a minimum penalty of total disqualification from that event.

Disqualified competitor will lose any prior placings, prize money, contingency money points and/or event awards at that event. If behavior deems a severer penalty, said penalty will by determined by ETPC or affiliated organisation board.

7.

An attempt is defined as moving the sled a measurable distance.

8.

All pulls made during a contest will be measured. All pulls will be measured from the starting line to the front of sled where it stops.

9.

Pulling vehicles must remain within boundaries of contest course during a pull or will be disqualified. Sled pan must be within boundary lines at start of pull.

Chalkline is to constitute track boundary.

10. Excessive loss of liquid by a pulling vehicle under the green flag, either in forward motion or standing still while hooked to the sled, will be cause for disqualification unless due to internal breakage.

(Excessive is defined as any steady or intermittent stream discharged on the track, or a spot equivalent to more than 200 mm diameter).

11. If a vehicle is legal when hooked to the sled, and if breakage occurs while under green flag due to unforseen circumstances - with the exception of loss of ballast or safety equipment - the pull will be measured.

2009 10-1

12. Any vehicle that hooks to the sled and makes a measurable pull shall be considered to have made an official hook even if the sled is reset and vehicle cannot rehook. The vehicle would be considered to have made a normal pull.

13. Only when the original mechanical method of starting fails to work, tow start will be authorized.

14. All pulling vehicles must be able to drive on the track and back up to the sled at the starting line. They must also be able to back up to unhook and drive off the track on their own power unless breakage occurs at the event or vehicle will be disqualified. If track circumstances (too much dirt or too deep holes) or technical problems with the tractor prevent the tractor from driving away from sled on its own power after pulling attempt, this will not be a reason for disqualification.

Minipullers are exempt from backing-up portion of this rule.

15. ETPC recommends that sled setting on international events will be done by sled operator together with the Senior Track Official. If the sled operator does not agree with the Senior

Track Official’s proposal, the Senior Track Official can, by his own decision, allow the sled operator to carry out first 2 pulls with his setting.

If the Senior Track Official is not satisfied with sled performance and/or sled setting, he can demand the setting to be changed. The final decision will be taken by Senior Track

Official.

16. Violation of any rule shall constitute a disqualification.

17. In the case of a class not completed because of rain, sledge breakage, etc. decisions are to be made by Track Official or/and Officials.

18. It is not allowed to drive a vehicle on its own power outside the closed area (track area and closed pit). Vehicles that make use of an auxiliary power unit are excluded from this rule.

19. The ETPC Tech and Safety Board has the right to take possession of any part(s) of a competing vehicle for closer inspection when necessary. After the inspection, the part(s) will be returned to the pulling team in question.

B. Track and track officials

1.

All official contests must have available a dirt track of 100 meters length and not less than 10 meters in width.

A safety run off area of 30 meters is required. Width to be an acceptable exit.

A minimum width of 10 meters on each side of the track is required as safety area.

At indoor pulls the measurements of the track area can be different.

2.

Crash barriers with a height of 60-75 cm or trenches 100 cm wide and at least 50 cm deep are mandatory on both sides of the track at Euro Cups and European

Championships. It is highly recommended for the distance of crash barrier or trench to be a minimum of 7 meters from the track, minimum of 2.5 meters from the spectators.

3.

All tracks must be maintained and packed after each pull.

4.

No one is allowed on the track except for the Track Officials and contestant when the vehicle is under the green flag. Track is defined as the area within 0.5 meters in any direction of the contest course boundaries, including the run off area at the end of the track.

5.

All pulls shall operate with two flagman. Starting flagman will be responsible for readiness of track, sled and contestant. Second flagman will be responsible for balance of course.

6.

Pulling or leaving starting line under red flag will be cause for disqualification.

8.

Each contestant has the privilege of, and the responsibility for spotting the sled for both of his/her attempts. Pull back tractor/loader/sled operator must be notified of where contestant wishes sled placed when previous contestant unhooks from the sled. Use of crew members is recommended for spoiling the sled to expedite the show.

C. Test pulls and options

1.

Number one puller will be test puller and may take his/her pull if weight transfer is deemed right. In case it was a test pull, the test puller will pull again after six (6) competitors have made their pulling attempts

2.

The number one or test puller is not disqualified or measured for running out of bounds on first attempt only. He is to be disqualified on second or subsequent attempts if he goes out of bounds.

3.

If weight transfer needs further adjustment, the first puller after each adjustment will be treated as the number one or test puller.

4.

All pulls must start with a tight chain. Contestant will be allowed a total of two attempts and 20 meters to start the sled. If the driver lets of the throttle before 20 meters he will get a second attempt, even if going beyond 20 meters. Result of first attempt will fall. If no effort is made to release throttle, no second attempt will be given The intent is for drivers not to slam the brakes to stop before 20 meters (or at any time), but to come to as smooth a stop as possible. Jerking the sled by backing out of the throttle will be considered a ground for disqualification by Track Officials. Track Officials will use their own judgment on this call.

5.

There will be no maintenance on the track before the second attempt.

6.

If the class is restarted, all contestants having pulled previously will have the same options as the number one puller. In the case of a restart it is the competitor’s responsibility to inform Track Official of his/her decision.

7.

A class can be re-started if the first five competitors have made a full pull.

8.

A driver’s decision on a re-pull has to be made before vehicle leaves the track area.

9.

Any disqualification on the first attempt bars a second attempt. Should class be restarted, puller disqualified will be allowed to pull in position drawn.

10. Contestants must pull at position drawn within three minutes after sled is at readiness.

Any delay will mean disqualification. If presiding first flagman is notified he may drop six positions. This may be done only once per contestant per class.

11. If a contestant experiences mechanical problems during a test pull (before first official pull), Track Official may grant the contestant the option of dropping to sixth or last position.

12. Contestant will be able to drop six places if breakage occurs on first attempt, if not past

20 meters. He will get a total of two chances.

13. If the last vehicle in a class experiences mechanical problems, it should be allowed six minutes to hook and make an attempt.

14. On any re-pull caused by a contest malfunction, the puller, at his discretion, may drop six positions.

15. When a competitor is test puller and the sled is reset after his pull to a lighter sled-setting, he is allowed to take that pull.

2009 10-3

D. Pull-offs

1.

In a pull-off each contestant in his/her turn will be allowed two attempts to make a measurable pull, if not past 20 meters.

Eurocups and European Championships 60 meters) provided that the pulling vehicle performs well: Possible re-adjustment is at the discretion of the Track Jury.

3.

If the first contestant succeeds in making a full pull, all contestants must pull at that setting unless in the Track Official’s opinion, the sled operator has made a mistake.

4.

A floating finish line - with a ten meter maximum - may be used at the discretion of the

Senior Track Official and/or Track Officials and only in a pull-off situation. Extended boundaries must be clearly chalked. Competitors must be informed in advance at the driver’s meeting and before the pull-off. Run-out area needs to be a minimum of 40 meters.

5.

Order of pull will be in the order in which the vehicles involved made full pulls, unless there has been a sled setting change by Track Official.

No dropping six positions in a pull-off.

Chapter 14:

ROLL OVER PROTECTIONS

1.

The Driver Roll Over Protection (ROP) has been designed in co-operation with specialists in order to protect the driver in the event of his vehicle tipping over during a tractor pulling competition.

2.

The design, or the ROP built according to the given specifications, are not to be understood as an automatic guarantee, as for providing an always adequate protection for the driver during an accident with the tractor.

3.

The ROP specifications must be seen as a set of minimum requirements and advisory guidelines.

4.

Neither the ETPC Board, the T&S Board nor any of their members can be made responsible for consequences resulting from the application of the ROP specifications or malfunction of the safety devices in question.

A. General Considerations

1.

The construction must allow an easy exit for the driver in the event of a fire etc.

2.

Tractors weighing more than 4000 kg are recommended to have a tube wall thickness

0.5 mm higher, or more, than specified.

3.

If team drivers or tractor constructors think that the ROP constructions specified below are not solid enough, they are free to make them stronger.

4.

All NTPA certified ROP cages are permitted by the ETPC.

5.

No ballast can be hung from or attached to any portion of the ROP-structure. Chassisattachment is exempt of this rule.

B. Construction

1.

Bending radius of all tubing should be as wide as possible, the minimum is two (2) times the outside diameter of the tube being bent.

2.

All fastening bolts must be grade 8.8 or better, this must be clearly marked on the head of the bolt.

3.

All welded joints must be welded by an experienced professional; a steel filler metal must be employed that is compatible with the base metal.

4.

All weldings must be done according to generally accepted welding practices.

5.

No grinding on any welding.

6.

All structural material for the ROP shall be seamless mild steel (carbon mechanical) tube or normalized chrome molybdene (DIN Norm 25 CrMo 4) seamless steel tube.

7.

Tubing diameters and wall thicknesses are nominal measurements.

8.

The dimensional locations of the main structural hoops and secondary tubing shown in the figures are to be used as guidelines but must remain within 20% of the dimensions specified in the figures.

The maximum backward inclination of the cage is 20 degrees.

9.

Tubing size and material shown in the figures and tables are minimum requirements!

10. There shall be a minimum of 50 mm between the main hoops and the driver s helmet, both vertically and laterally, with the driver seated in normal position.

11. In order to avoid possible neck injury, the horizontal distance between the main hoops and the driver’s helmet must not be over 200 mm.

2009 14-1

12. It is recommended that the fastening construction of the ROP cage to the tractor frame is significantly stiffer than the ROP itself.

13. It is also recommended that the driver’s seat should be so constructed that it provides adequate back and shoulder support during an accident. The seat should be mounted to the ROP cage, or the lower support structure with at least four (4) M8 grade 8.8 bolts.

The seat back should be bolted to the rear main hoops, and the seat should include a head rest.

14. The use of a 4-point seat belt or better is mandatory. The seat belt must be attached to the roll-cage.

C. Remarks

The T&S Board will allow options ‘B’ or ‘C’ to be applied where ‘A’ is not technically possible

(see drawings).

1.

If ‘A’ is used, then both hoops from rear to front must be of one-piece tube.

2.

If ‘B’ or ‘C’ is used, an additional tube ‘S’ must be added to the ROP, and the front hoops must be out of ONE piece.

3.

If ‘C’ is used, then the both side-to-side hoops must be out of one-piece tube. In general, you should have as few weldings as possible and do them according to the drawings.

Basically, no weldings are allowed on the main hoops, if you must weld a main hoop, please ask the T&S Board.

It is highly recommended to move the front hoop aft to allow quick exit in the event of fire or other mishap.

See next pages for drawings/illustrations.

ROP-cage mounting on tube type chassis

Illustration 14-4: Mounting ROP on tube type frame

Recommendations regarding mounting the ROP-cage to any tube type chassis

Vertical ROP-cage supports can be welded directly to horizontal tube frame structure.

Use steel supports to be installed directly between horizontal frame tube and in line with each vertical ROP-cage tube, this steel supports 80 mm x 6 mm min. (50 mm x 6 mm min. for mini’s) must extend to the next horizontal frame tube directly below.

Rear ROP-cage vertical tubes can be welded directly to a rear structure same as the side frame. This rear frame structure can be welded to the vehicle frame.

Support webs of 80 mm x 6 mm min. (50 mm x 6 mm min. for mini’s) can be welded between vertical tubes on both sides and rear tubes.

2009 14-6

ROP-cage mounting to OEM rear-end housing

Illustration 14-5: Mounting ROP on OEM rear-end housing

Recommendations regarding mounting the ROP-cage to any stock OEM rear-end housing

Try to create a rigid one piece assembly on tractor rear-end for maximum strength.

Do not use material thinner than 6 mm.

Create two ‘U’-shape attachment flange’s to use the side flange bolts (four (4) min. each side) to keep the assembly in place.

Use four additional bolts (min. M12 grade 8.8) to attach the assembly to the axle housing, two before and two after the axle housing.

Weld the assembly solid together without grinding on any welding.

Support webs of 80 mm x 6 mm min. (50 mm x 6 mm min. for mini’s) vertical from base plate must be welded between vertical tubes on both sides and rear tubes, to create a solid connection from ROP-cage to rear-end.
