strength in order to avoid turn being transmitted from the old rope into the new rope. Alternatively a length of
fibre or steel rope of adequate strength may be reeved into the system for use as a pilot/messenger line. Do not
use a swivel during the installation of the rope.
Monitor the rope carefully as it is being pulled into the system and make sure that it is not obstructed by any part
of the structure or mechanism which may cause the rope to come free.
Failure to monitor during this operation could result in injury.
This entire operation should be carried out carefully and slowly under the supervision of a competent person.
When coiling a rope on a plain (or smooth) barrel drum ensure that each lap lies tightly against the preceding
lap. The application of tension in the rope greatly assists in the coiling of the rope.
Any looseness or uneven winding will result in excessive wear, crushing and distortion of the
rope.
When multi layer coiling has to be used it should be realized that after the first layer is wound on a drum, the
rope has to cross the underlying rope in order to advance across the drum in the second layer. The
points at which the turns in the upper layer cross those of the lower layer are known as the cross-over points
and the rope in these areas is susceptible to increased abrasion and crushing. Care should be taken when
installing a rope on a drum and when operating a machine to ensure that the rope is coiled and layered
correctly.
Limit switches, if fitted, must be checked and re-adjusted, if necessary, after the rope has been installed.
Record the following details on the Certificate after installation has been completed: type of equipment, location,
plant reference number, duty and date of installation and any re-rating information/signature of competent
person. Then safely file the Certificate.
Run in’ the new rope by operating the equipment slowly, preferably with a low load, for several cycles. This
permits the new rope to adjust itself gradually to working conditions.
Unless otherwise required by a certifying authority, the rope should be in this condition before
any proof test of the equipment or machinery is carried out.
Check that the new rope is spooling correctly on the drum and that no slack or cross laps develop. Apply a back
tension in the order of 2% to 5% of the strength of the rope in order to achieve tight and even coiling especially
on the first layer..
Where multi-layer coiling is unavoidable, succeeding layers should coil evenly on the preceding layers of rope.
Irregular coiling usually results in severe surface wear and rope malformation, which in turn is
likely to cause premature rope failure.
Ensure that the as-manufactured condition of the rope is maintained throughout the whole of the handling and
installation operation.
4.4 START UP SEQUENCE
1. Check lubricating oil level and fill up if necessary;
2. Make a few trials without load before fitting the wire to check a correct operation of the system;
3. Fit the wire as described in section (4.3);
4. Make a few lifting trials with reduced load to check the correct operation of the brake and the limit
switches (optional), pay attention to excessive or unexplained noises;
5.
Check for correct working of the load limiting device (optional).
