Figure 21. Risk of slipping
There is a risk of slipping as the surfaces of the trailer can be slippery due to precipitation in
combination with pre-existing oil and/or clay on the surface. The ground around the trailer
can also become slippery, as the tyres can tear up the surface and expose clay and soil.
Figure 22. Hydraulic fluid under pressure
Hot hydraulic fluid at high pressure levels can occur in the hydraulic system. Take care
when connecting, and replace poor quality hoses.
Figure 23. Using the exchange unit
The exchange unit may not be operated unless the frame is folded down. During transport
with the trailer, the hook must be folded down in the parking position.

Figure 24. Use the safety support during all service
Leaning under the raised frame is absolutely prohibited unless it is blocked with
the safety support. Under no circumstances may the trailer be carrying either a
load or a container when using the safety support.
Figure 25. Max. load
It is absolutely prohibited to load more than the amount your model is intended to
handle. This can result in danger to you and your surroundings.
Figure 26. Max. pressure on towing eyelet
Ensure that you do not load in such a way that the pressure on the towing eyelet
exceeds the permitted laws and regulations. The trailer is designed for a
maximum pressure of 3,500 kg on the towing eyelet. The pressure is largely
determined by the way the load is distributed on the container bridge, and it is
the user’s responsibility to ensure that this is not exceeded.

3. FUNCTIONAL DESCRIPTION
3.1.
HANDLING IN ROLL ON – ROLL OFF
If your BIGAB is equipped with suspension there is no bogie blocking.
Exchange and tipping must be operated from the operator’s seat in the towing vehicle!
Figure 1
Ensure that the position selector
for exchange or tipping is in the
exchange position, not in the
tipping position.
Figure 2
Place the hooklift trailer on a flat surface. The sideways incline may not
exceed 5 degrees.
Failure to read this instruction manual can be potentially fatal!
Under no circumstances may you reverse/exert pressure with the towing vehicle in order to
facilitate exchange. This entails an immediately risk of the trailer or the towing vehicle
being damaged, which can be potentially fatal. The load must be pulled on and the trailer
and the towing vehicle must roll in under the freely suspended load.
© 2009 Ver. 2 Fors MW Ltd
www.forsmw.com
22
17-20
STOP
Stop if the tractor lifts off the ground!
Figure 3
Check that the hook hitches
around the loop.
On-loading!
Check that the frame lock and bogie blocking are
activated.
 Check that the load carrier is inside the discs. Release the brakes on both the towing vehicle
and the trailer to make it easier to roll on the load. Check the position of the tower during
on-loading so that the container bridge’s frame does not catch on the rollers from behind.
 The tower must be fully retracted when rolling on the container bridge in order to increase
lifting force and reduce the strain on the towing eyelet. Ensure that the container frame does
not catch in the rollers at the back of the trailer. Adjust the tower upwards continually during
exchange in order to move past the rollers. If the tower is not adjusted upwards during onloading, there is a considerable risk of the exchange’s lock being damaged if the container
frame catches in the rollers.
IMPORTANT! Follow the movement with the retractable tower so that the
front of the hooklift trailer’s frame does not catch on the rollers. When you
have passed the rollers, always keep the hooklift trailer’s frame close to the
rollers.
Figure 4
Off-loading!
Release the brakes on both the towing vehicle and the trailer to make it easier to roll off the
load. Check the position of the tower during off-loading so that the container bridge’s frame
does not catch on the rollers from above.
Lock the frame and activate bogie blocking between the towing vehicle and trailer.
1. Raise the hooklift frame slightly so that the container bridge does not scrape against the
frame when off-loading the container bridge.
2. Then retract the tower so that the locking rails/wings on the container bridge frame move
freely and cannot be damaged.
3. Adjust the tower upwards continually so that the container frame does not catch on the
rollers at the back of the trailer during off-loading.
4. If the tower is not adjusted upwards during off-loading, there is a considerable risk of the
exchange’s lock being damaged if the container frame catches in the rollers.

HANDLING IN TIPPING
Note! For the models mentioned in this instruction manual, the maximum container bridge length is
6.0 m during tipping. Ensure that the towing vehicle and the trailer are securely coupled before
tipping.
Figure 1
Ensure that the trailer is in the tipping position
and not the exchange position before
commencing tipping!
Figure 2
Place the hooklift trailer on a flat surface. The sideways incline may not
exceed 5 degrees.
Figure 3
At maximum tipping – drive slowly forwards until the container bridge is empty.
Lower the container bridge before continuing to drive. Important! Ensure that the
container bridge is locked in the correct position before driving.
IMPORTANT!
When tipping, use the brakes to
ensure that the machine does not
roll away when the load slides off.

3.3.
OPERATION WHEN DRIVING
It is the responsibility of the user to ensure that a sufficiently powerful and heavy towing vehicle is
coupled to the trailer in all situations. The use of a towing vehicle that is too small and insufficiently
powerful can entails risks for the user and the surrounding environment, as well as leading to
damage to the vehicle and trailer.

4. SAFETY INSTRUCTIONS
IMPORTANT:
READ AND UNDERSTAND THE USER MANUAL CAREFULLY BEFORE
USING THE DEVICE. CONSULT THE USER MANUAL TO SOLVE YOUR
PROBLEMS. THE DEVICE HAS AN IDENTIFICATION LABEL ON IT.
BEFORE USING THE TRAILER, ENSURE THAT FACTORY SETTINGS
HAVE NOT CHANGED AND THERE ARE NO PARTS BECOME LOOSE
DURING TRANSPORTATION. MAKE SURE THAT ALL WARNING SIGNS
LABELS AND TAPES ARE IN THE APPROPRIATE PLACES.
THE TOWING EYELET MUST BE CONTROLLED FOR DEFAULTS EVERY
TIME BEFORE THE TRAILER IS USED. THE TOWING EYELET NEEDS TO
BE CHANGED AT LEAST ONCE A YEAR. IT IS UP TO THE USER OF THE
TRAILER TO SEE IT THAT THIS IS DONE.
4.1.
GENERAL
Before you start to work:
•
•
•
•
•
•
•
•
•
•
•
•
•
•
•
•
•
Carefully examine the trailer.
Check that all joints are connected tightly.
Check that the trailer is located on hitch hook.
Check the towing eyelet for defaults.
Control brakes.
Control the lights.
Check that the brakes are functioning.
Check that hydraulic hoses and couplings are intact and free from cracks.
Check that all hydraulic functions are working.
Remember that it is not allowed to use this unit for functions not confirmed by producer.
Be aware that a long container needs enough working space and turning area.
Respect the safety distance.
Never stand by the drawbar when connecting and disconnecting or when functions
between the towing vehicle and trailer are activated.
Be sure that nobody is in the working area of the trailer.
Do not exceed maximum loading values.
Always engage the base machines parking brakes before loading. If necessary put some
obstacles in front of wheels.
Study safety instruction.
During maintenance:
•
•
•
•
Be sure that the trailer is standing on a flat surface.
Be sure that the trailer can’t move.
When lubrication or servicing the trailer, turn off the vehicle engine.
Be sure that the trailer can’t slip when using support leg, jack or similar equipment

17-20
•
•
•
•
•
Always use the security post in tipping position when servicing. The safety support must
always be used when carrying out service work in the tipped position. There must not be
any load on the trailer when carrying out service work in the tipped position. See figure
below.
Never attempt to do maintenance work on the hydraulic system before you are sure there
is no pressure.
Do not tighten or repair leaking hydraulic couplings while the system is pressurized.
Never attempt to localize a leakage from hoses or connections by feeling with hand. The
high-pressure oil jet can penetrate skin and cause serious burns and damages. Highpressure oil is also highly flammable.
Avoid getting oil into eyes. Use safety goggles and gloves. If oil has got into eyes flush
them with cool water and immediately contact a doctor.
Figure 36. Safety
Note!
It is strictly
forbidden to lean
under the container
body without using
the security post!

Driving:
•
•
•
•
•
•
•
4.2.
Don’t forget to lift the support leg up before driving.
Do not exceed maximum travel speed.
Never make sharp turns at great travel speed.
Long container needs enough working space and turning area.
Do not exceed maximum loading values
Be sure that the container is firmly fixed before driving.
Recommended load placement - symmetrical.
WORKING AT EXTREME CONDITIONS
Recommended working temperature range for a Bigab trailer is –30°C up to +40°C.
Note that working at low temperatures accelerates hydraulic gaskets wearing and increases
hydraulic hoses exposure to damages and steel constructions exposure to brittle fracture. When
working at lower temperature than recommended, lift lighter loads than usual.
Before starting to work in cold conditions let the oil circulate freely through the system a
few minutes. Slowly work every action through several times so that gaskets come pliable before
they receive full pressure.
At exceptionally warm conditions beware of hydraulic oils excessive heating. Too high oil
temperature (higher +80°C) degrades oil and damages gaskets.
4.3.
ACTING IN DANGEROUS SITUATION
If the trailer comes into contact with high voltage electric wires comply with the
following instructions:
IF YOU ARE OUTSIDE THE MACHINE
Do not attempt to get into the machine. Keep everybody out from the machines vicinity. Do
not touch any part of machine.
IF YOU ARE INSIDE THE MACHINE
Get out of it by JUMPING. Avoid touching any conducting parts. Do not make yourself a
wire through which electricity may flow. Get away from the machine by JUMPING so that both
feet do not touch the ground at the same time. Electric field at ground can cause fatal voltage
between legs. At about 20 meters away you should be safe but this is of course a question of
circumstances.

5.2.2. Maintenance of the hydraulic units
Hydraulic system is shown in chapter 3.4.
•
•
Clean and lubricate piston rods of hydraulic cylinders.
Check the hydraulic valves:
Check visually hydraulic valves. In case of leaking replace the damaged valve.
• Check hydraulic hoses:
Check visually hydraulic hoses and union pipe connections. Replace a hose in case of
leaking or if there are ruptures or slashes on it.
• Check the level of oil, add and replace oil.
• Check the operation of the device.
When replacing hydraulic components such as hoses, gaskets etc, make sure they
correspond with original parts. To avoid malfunctions and ensure safe operation use original spare
parts.
Changing the seals
Change all cylinder seals at the same time. The piston cannot be split. The seals must be
slipped over the piston edge. Be careful not to break the seals when fitting them in place.
• After removing the old seals clean the grooves carefully before fitting the new seals into
place.
• Lubricate the new seals with hydraulic oil.
• Open the pistons lock nut.
• Screw the piston off.
• Withdraw the guide piece from the rod.
• Change the guide piece seals; make sure that the piston rod seal is the right way round, i.e.
the lip against the pressure.
NB: Never operate the hydraulic system with the level of oil dropping below
the lower mark.
5.2.3. Maintenance of the pneumatic units
•
•
Clean and lubricate piston rods of pneumatic cylinders.
Emptying the water collector:
Condensed water is removed from the air tank located in the side of trailer.
• Check the pneumatic valves:
Check the pneumatic valves by listening to the working sound. In case of leaking replace the
damaged valve.

17-20
5.2.4. Maintenance of the electrical components
The trailer is manufactured with 12V electrical system. Electrical system is shown in chapter
3.3.
The wires to the electrical equipment are of different colors, which facilitate the location of
the wire leads connecting individual items of the electrical equipment. Refer to the electrical
diagram (figure 23) to ensure a correct subsequent reconnection of the electrical units and also
when checking the operation of the equipments and individual electric circuits.
•
Clean and check the lights:
In case of fault replace the lamp. If the lamp keeps on braking repeatedly, find out the case
of the matter.
• Check electrical connectors:
Clean them of dirt and dust.
• Check wires insulation:
Check wire insulation, wire joints and protection of insulation against rubbing during jolting
and contacting the trailer parts. Protect the wires from oil and fuel, which ruin insulation. Wipe
dirty wires.
NB: Join and disjoin plug connectors only with dead circuits.
5.2.5. Maintenance of the brake system
The trailer is manufactured with a hydraulically functioned brake system. Air brake system
with negative or positive action is optional.
Control the brakes regularly. Test the brakes at least once per week while trailer is
working.
See to it that no lubricant penetrates into the brakes. Any lubricant, which has penetrated
the brake, causes greasing of the disks, thereby reducing friction between their working surfaces. A
poor operation of the brakes is the result of such happening. In such a case dismantle the brake,
eliminate the oil leakage, wash the greasy disks with gasoline and let them dry out.
Control always the brake control linkage after the drum being dismantled, adjust if needed.
For adjusting the brakes you need to lift up the bogie-frame from the ground and adjust the
brake levers. You do this by spinning the wheel while adjusting. The brakes are correctly adjusted
when they spin freely without any scraping noises from the wheel. After all kinds of adjusting in
regards to the brakes, always carry out a practical brake test before driving away.
If the brakes seems to work grainy, found the brakes, pull the trailer maintaining low speed
for a couple of hundred meters, try again through braking the vehicle while driving in a normal
speed. Keep on reiterate until the brakes functional normally. If necessary contact our service
department!
BIGAB models 7 – 10, 8 – 12 and 10 – 14 – the brake show distance to the drum needs to be
adjusted through loosening and by doing so adjusting the brake control linkage.
BIGAB models 12 – 15, 15 – 19, 17 - 20 and 20 – 24 – the brake show distance to the drum on the
brake cylinder needs to be adjusted through loosening or vice versa tightening the adaptable screw
on the brake.

5.2.6. Maintenance of wheels
The maintenance of the wheels before proceeding to work consists in watching over the
condition of the threaded joints and timely tightening there of and in observance of the rules for use
and maintenance of tires.
•
•
Check the threaded joints.
Check the pressure of air in the tires.
Wheels pressures see table 2.
Tightening torque for nuts see table 4.
5.2.7. Maintenance undercarriage
Every day
It is necessary to visually check the nuts on the bogie side each time the customer uses the trailer.
Weekly
Once per week (or nor later then 20 hours) it is needed to lubricate the grease nipples You need to
lean under the trailer to be able to grease the glide bearings. This will be easier to do if the trailer is
without load.
