3.4 WORKSPACE
!
By this we mean a clear space around the drive and idler units of around 1500mm.
From within the workspace all operations and servicing can be carried out. Ensure that
any protrusions on the vessel cannot cause any injury or damage.
3.5 EMERGENCY STOPS
I
It is vitally important for the safety of the operators and any other personnel in the
area of the rotators, that the operator fully understands the location and how to use
the emergency stop buttons on the machines. It is also recommended that other
personnel that work in the vicinity of the rotators are also aware of the positions of
emergency stop buttons, so they can stop the equipment if the operator requires
assistance or is trapped by the machines
Firstly all new operators should be made aware of these emergency stop procedures.
There are two emergency stop buttons fitted to the rotators, one is located on the panel mounted on the
drive unit, the second is mounted on the pendant.
Pressing either of these two buttons will immediately bring the rotators to a stop, and all controls will be
locked.
In case of personal injury, help can be given immediately, also if there is other urgent action required this
can be carried out immediately.
After the hazard has been resolved and after checking the machine can be safely operated again, the
emergency stop button needs to be released by twisting it in the direction of the arrows printed on it.
Once this is done the reset button on the panel needs to be pressed and will illuminate. Once the light
comes on, the rotators will not restart again, until a direction button is pressed. Normal operation will now
continue.
Note either emergency stop button can be used to stop the machine but operation can only restart again
once the reset button is pressed.

I
We recommend
 New operators are allowed to practise with the emergency stop switches
 The Emergency Stop is tested at the start of every shift
NEVER DISCONNECT OR BYPASS THE EMERGENCY STOP BUTTONS

4.0 OPERATING INSTRUCTIONS
Before operating the rotators please ensure that you have read Chapter 2 – “Safety”. This chapter of the
manual is meant for the operators, though all people concerned with the machines should read it.
4.1 MACHINE DETAILS
The rotator set will usually consist of one drive unit and 1, 2 or 3 idler units.
The idler unit basically consists of a base frame with two wheel brackets bolted onto the top of it. There
are holes drilled through the top of the baseframe so that the wheel brackets can be positioned at
different distances apart, to suit the vessel diameter.
The drive unit again has two wheel brackets and similar to the idler unit these can be positioned to suit the
vessel diameter. Either one or more usually both wheel brackets will be motorised (depending on the
model). The wheel is turned by and electric motor through a reduction gearbox. The motor is connected
back to the panel on the drive unit. Inside the control panel is an inverter which controls the motors. There
is also a hand pendant on a flexible cable connected to the panel.


We recommend that the operator always presses stop, before changing the rotation
direction.
4.4.1 SET UP
After delivery and setting into place these rotators will be ready for use.
Firstly choose a place for the rotators to be located. This should have suitable access to the machines. Also
enough space around the machines including vessel when loaded. It should also be positioned in such a
way as to allow easy unhindered load and unloading of vessels onto the rotators by either overhead crane
or other lifting devices.
!
Always ensure that there is sufficient space around the machine. See section 3.4 of
this manual.
When moving the rotators, the correct lifting equipment must be used. Either correctly rated overhead
cranes or forklift trucks can be used.
!
Forklift Truck: When lifting the rotators using a forklift truck, use the slots in the long
side of the frames for the forks. Take notice of the positions of the wheel brackets on
the frames in case they cause an imbalance when lifting the frame. Ensure that they
are both at an equal distance from the centreline of the frame, and that they are
properly bolted to the frame and will not move during lifting.
Lifting by crane:
The rotators can be lifted by using the lifting points on the
rotator wheel brackets. One lifting point on each side of the
wheel bracket should be used, (4 lifting points in all). It is
desirable that the angle between the chain and the lifting
points on the rotators makes a 60 angle (see figure 3).
Figure 3 Lifting Chain Angles
The rotators should be placed on a smooth, level, hard floor that is capable of taking the weight of the
rotator and vessel, over the contact area of the rotator with the floor.
The distances between the baseframes should be such as to match the vessels dimensions. Ideally if the
vessel is perfectly symmetrical and 1 drive with 1 idler are being used. The drive and idler should be one
third of the way along the vessel length to ensure that equal load is put onto each section. If more weight
is at one end of the vessel, then drive or idler section should be moved closer to this end to again balance
the loading on each section.

$
It is important to balance the loading equally between the drive and idler section(s).
Failure to do so may result in overloading one of the sections which will cause
problems when trying to rotate the vessel (wheels slipping). It can also result in backdriving where the vessel can continue to rotate after stopping the rotators. If observed
this must be rectified by correctly positioning the drive and idler section, failure to do
so will cause damage to the equipment.
!
WARNING! As soon as one of the direction buttons (Forward or Reverse) is pressed
then the rotators will begin to turn the vessel.
4.4.2 ADJUSTING THE WHEEL BRACKETS
The operator will need to adjust the positions of the two wheel brackets on the baseframe, so that vessels
of different diameters can be loaded.
To do this, the operator needs to;
1.
2.
3.
4.

Unbolt the wheel bracket from the baseframe.
Use a crane to lift the wheel bracket using the lifting points.
Move the bracket to the required position for the diameter of the vessel.
Bolt the wheel brackets back onto the baseframe using all the bolts, and tighten.
We recommend that the wheel brackets are always adjusted so that the axis of
rotation of the vessel, is on the centre line of the drive and idler frames of the set of
rotators.
See section 4.6 for details of the distances between the two wheel brackets
4.4.3 INCLUDED ANGLE
The distance between the wheel brackets on both the drive and idler sections will depend on the diameter
of the vessel. The included angle must be between 50 and 80, but we recommend setting the rotators up
always as close to 60 as possible.
The included angle is the angle between two lines from the centre of the rotation axis of the vessel to the
centre of each wheel on the drive or idler section. It is of importance, as the angle increases so does the
resulting load on each wheel, and consequently the load on the bearings. Also by increasing the angle
more torque, and therefore more power, is required to rotate the vessel.


You can quickly calculate the distance that the wheel brackets need to be apart in
order to achieve a 60 included angle. It is;
4.5.1 SWITCHING ON
Before switching on the rotators, check the following;




Are the wheel brackets correctly bolted down on the base-frame.
Visually inspect the wheels, motors, gearboxes, pendant, panel and cables for any signs of damage.
Are the wheels correctly positioned under the vessel?
Are there any obstructions to prevent rotation of the vessel (if one is loaded)?
!
WARNING! Do not operate the rotators if there are signs of damage, always have a
service engineer to check these over and make repairs if necessary.
Once the operator is satisfied that the rotators are in good order, plug in the mains lead to the power
supply.
!
!
WARNING! Check that the mains power supply matches the electrical voltage shown
on the panel.
WARNING! Ensure that the mains and pendant cables, do not cross lanes where
forklift trucks or other vehicles can run over them, and they do not create a tripping
hazard.
Switch on the mains power, and the Power On lamp on the control panel should illuminate.

Conventional Rotators Model RDA-CR20UL
Check that the emergency stop buttons are not pressed in, and then press the reset button.
The machine is now ready to operate.
4.5.2 OPERATING THE ROTATORS
Once the operator is happy the rotators are correctly aligned and the wheel brackets are in the correct
position, they may then load the vessel on the rotators. This must be done steadily, so as not to shock load
the rotators. If the rotators are shock loaded then this will cause damage to the drive chain.
Ensure that no protuberances on the vessel can strike objects around the rotators, or the floor during
rotation.
The operator should then set the speed potentiometer knob (see figure 2) to the desired speed.
Then press the desired travel direction (GREEN or YELLOW button) the rotators will then start to turn the
vessel.
4.5.3 WELDING
It is important that the user is aware of the earthing requirements of their welding procedure, and that
this is correctly connected to the vessel before welding. Standard rotators are not designed to earth the
vessel during welding.
!
WARNING! When welding, the vessel MUST be earthed independently of the rotators.
Earthing through the rotator will cause serious damage to the rotator sets.
The only exception to this would be, for special steel wheel rotators which have been
fitted with an earthing point. In which case it is essential that the earth cable is
connected properly at this earthing point, before welding.

It is good practise to keep the rotators clean. Any arc sparks, flux or slag that falls onto
the rotators should be removed as soon as is possible.
4.5.4 STOPPING THE ROTATORS
To stop the rotators, press the RED stop button on the hand pendant. This will stop rotation. Rotation will
start again when a direction button is pressed.
If necessary the rotators can be stopped using the Emergency Stop Button on either the panel or hand
pendant. This should only be used in an emergency.

Conventional Rotators Model RDA-CR20UL
4.6 COMMON MISTAKES WHEN USING CONVENTIONAL ROTATORS
1. Placing multiple drives under one vessel. This is only possible if special Master and Slave
synchronised control panels have been supplied with the rotators. In which case the master panel
controls the slave drive.
2. Parts of the vessel come into contact with the rotators, floor or objects in the vicinity during
rotation. This can cause damage to the rotators and cause the wheels to slip or overload the units.
3. No proper earthing during welding. This can cause the electrics on the rotators to short out.
4. Emergency Stop button is depressed. If a switch is pressed in, the operator must find out who
pressed it in and for what reason, before restarting the machine. There may be a hazard that
someone else has seen and stopped the machine for.
5. The distance between the wheel brackets is too large, thus
causing more load to be put through each wheel. This in turn can
cause the rotators to be overloaded.
Figure 5 Wheel Brackets Too Far Apart
6. Wheel brackets are too close together.
I
This is a very unsafe position. During rotation the
vessel could now roll off the rotators causing very
serious injury to anyone in the vicinity of the rotators.
It can also happen if there is an out of balance load
i.e. the centre of gravity of the vessel is offset from
the axis of rotation. The rotators should never be
operated at an included angle of less than 46.

7. If the drive and idler units are not aligned parallel to each other then the vessel can creep
lengthways and even fall off the rotators. This can also cause wear and damage to the wheels of
the rotator. See Figure 7 below for correct alignment details.

4.7 BREAKDOWNS
If the rotators stop working, then the equipment must only be repaired by qualified service personnel.

If there are repeat faults, then this could indicate a problem with the machines. Inform
the person on site that is responsible for service and maintenance.
4.8 CLEANING
These rotators require no special cleaning instructions. The rotators should not create any pollution to the
environment around them during normal operation, although, the welding process being carried out on
them may pollute the rotators.

!
It is good practise to keep the rotators clean. Any arc sparks, flux or slag that falls onto
the rotators should be removed as soon as is possible.
WARNING! Rotators must be electrically isolated before cleaning. Any electrical
components must not come in contact with water or other cleaning fluids.

5.0 MAINTENANCE AND SERVICING
This chapter should be read by all service engineers that will be working on these rotators.
5.1 GENERAL
!
!
WARNING! During all maintenance or repair procedures, the rotators must be
electrically isolated. Do this by switching off the main electrical supply and unplugging
the mains cable.
WARNING! After disconnecting the power there may be some residual charge in some
components in the panel. Wait a few minutes after disconnecting the mains power
before commencing work on any electrical elements of the machine.
5.2 INSTALLATION
Before first use, or after maintenance or repair work, or after a period of the rotators being in storage,
they will need to go through this installation procedure.
Before the rotators were despatched from the factory, they will have been fully tested on correct
functioning and therefore they can be directly put into operation without the need for any further test
time. We would though recommend that the operations of all controls are tested before the equipment is
put into the production process.
Before starting up, check the following;







All moving parts can freely move (wheels)
Check oil level in the gearbox (see appendix D for Lubrication of the gearboxes)
Check the integrity of all cables, mains and hand control pendant, make sure there are no cuts etc.
Check the hand pendant controls all operate correctly.
Check the Emergency Stop on the Pendant works, and locks all other controls so the machine cannot restart
then reset on the panel.
Check the Emergency Stop on the Panel works, and locks all other controls so the machine cannot restart
then reset on the panel.
Check the steel framework to ensure it is straight and free from damage.
5.3 FIRST TIME RUN IN
In order for the worm gearbox to reach its optimal efficiency, when first installed the rotators should be
run in both directions for the following periods of time.



At least 8 hours running with no load on the rotators
10 hours running with one third loading.
15 hours running with two third loading.
After running in for the above the rotators can be run with full loading.

The Gearbox oil should be flushed out and changed after the first 100 hours of
operation. After this period follow the lubrication guide in Appendix D.

5.4 STORAGE
There are no specific requirements for storage other than they are stored in a cool dry place. After a long
period of storage the machines will need to be checked over thoroughly before being put into use again.
!
$
WARNING! After storing or transporting the rotators in a cold climate and moving
them into a warm location, there may be a build up of condensation within the
machine and electrical controls. To prevent damage, allow the machine to adjust to
the new environment temperature.
Do not store these rotators outside unprotected. The rotators should be sheeted, and
bare metal areas, bearings, gears and shafts suitably greased to prevent corrosion.
5.5 REPAIR AND MAINTENANCE
These rotators are designed and constructed to the highest standards, using high quality components. As
such this equipment should expect to have many years of operational life with only a minimal amount of
regular maintenance.
To continue the longevity of the equipment, all efforts should be made to keep the rotators clean and free
from dirt or waste from the welding process.
In addition the gearbox oil levels should be checked regularly and kept at the correct levels, see Appendix
D, for more information on gearbox maintenance.
At least one per year the whole installation should be inspected with particular attention paid to the
following;
 Poor electrical contacts
 Switches and controls
 Loose mechanical parts, ensure all fixings are correctly tightened
 Condition of tyres on wheels (if fitted)
 Condition of solid steel wheels (if fitted)
 Check wheels rotate truly (i.e. no eccentric rotation around the axles).
 Metal corrosion
 Fame damage
 Check for signs of damage to the wheel bearings.
 Follow maintenance procedure for the gearboxes in Appendix D
 Check all cables for damage (mains, pendant and also any visible cable running from the panel to
the motors).
 Check the emergency stops and also the correct functioning of the panel door isolator.
 Remove guards and check the condition of the spur gear and pinion on the drive wheels.
If there is any excessive damage then the parts should be removed and replaced with new.

APPENDIX D – GEARBOX MAINTENANCE
 INSPECTION AND MAINENANCE
To ensure these rotators have a long service life you should regularly check and change the oil in the
gearboxes. Also the following maintenance checks should be regularly carried out.
1. Except for the first oil change, the oil in the gearbox should be changed every 2500 hours or 6 months.
2. Check if the seal is leaking or irregular.
3. Check if there are any unusual noises during operation. If yes, the bearing may be broken.
4. Check the breathing hole of gearbox is obstruction free.
5. To aid cooling of the gearbox it is recommended that the external housing is kept clean.
6. Check the bolts, re-tighten any that are loose.
 LUBRICATION
The gearboxes on the rotators were filled with the proper quantity of lubricant before leaving the factory.
Please see the following table of recommended oils to use in the gearboxes. Note do not mix oils of
different brands. Instead drain the oil from the gearbox before refilling with a different brand.
