- Ensure that there are no obstructions around the machi-
ne which could prevent the machine, the wire rope and
the anchor points from operating in a straight line.
- Never use the JOCKEY ™ wire rope as a sling.
- Never apply a load to the loose wire rope exiting from
the JOCKEY ™ machine.
- Never subject the controls to sharp knocks.
- Do not operate the JOCKEY
™ machine so that the talu-
rit pressing of the wire rope hook fouls the machine side
case.
- Never attempt to reverse the rope completely through
the machine whilst under load.
12. TROUBLESHOOTING
1) The forward operating lever moves freely and does
not operate the mechanism : the machine has been
overloaded and the shear pin has sheared. See section
8.2 for replacing the shear pin (Jockey
™ J5).
2) Pumping :
A lack of lubricant in a machine sometimes brings about
a condition known as ‘pumping’ which is not at all dan-
gerous but which is inconvenient. This situation occurs
when the jaw which is gripping the rope becomes locked
onto it preventing the other jaw from taking over the
load. As the operating lever is moved in one direction
the machine travels a few centimetres, but when the
operating lever travels in the other direction the machi-
ne moves back the same distance in sympathy with the
jaw which is locked onto the rope. The JOCKEY
™ machi-
ne should be thoroughly lubricated and it will recom-
mence working normally. If necessary, operate the
machine in reverse direction over a short distance to
help lubrication of the mechanism.
3) Jerkiness :
This is also a symptom of lack of lubrication. The JOC-
KEY
™ machine should be thoroughly lubricated. Follow
the instructions for ‘pumping’ above.
4) Blockage :
If the wire rope becomes blocked in the machine, gene-
rally because a damaged section of wire rope is stuck
within the jaws, it is imperative to stop operating the
machine. The load should be taken by another machine
on a separate wire rope, or by another means, whilst
ensuring that all safety precautions are taken. When the
blocked machine is no longer under load, it may be relea-
sed and removed. Should this not be possible, return the
machine and wire rope to an approved repairer.
13. REGULATORY CHECKS
Company with salaried personnel operating a JOCKEY ™ or JOCKEY ™ J5 lifting and pulling machine
are required to apply the labor regulations governing safety.
It is also the responsability of every company to ensure that their employees have been fully and
properly trained in the safe operation of their equipment.
Check that the labels are in place.
Replacement labels can be supplied on request.
