(1) The load shall not be less than 110% of the rated load nor more than 125% of the rated load, unless otherwise recommended by the manufacturer or a qualified person.
(2) The winch shall have a minimum of five wraps of rope on the drum during the load test.
(3) The load shall be applied to the winch and held by the winch brake(s).
(4) A written report of the test shall be prepared and placed on file by the final stage manufacturer.
SECTION 7-2.3: MAINTENANCE
6) 7-2.3.1 Preventive Maintenance
A preventive maintenance program shall be established. The maintenance program shall be based on the winch manufacturer’s or a qualified person’s recommendations. Maintenance records should be made available.
7-2.3.2 Maintenance Procedure
(a) Before adjustments and repairs are started on a winch, the following precautions shall be taken:
(1) Requirements of ANSI/ASSE Z244.1 for lockout/tagout shall be met for the maintenance activity to be undertaken.
(2) Drum pawis shall be engaged, or other means shall be provided to prevent inadvertent rotation of the drum.
(b) After adjustments and repairs have been made, the winch shall not be returned to service until all guards have been reinstalled, limit devices reactivated, and maintenance equipment removed.
7-2.3.3 Adjustments and Repairs
(a) Adjustments and repairs shall be performed by a designated person in accordance with the instructions of the manufacturer or a qualified person.
(b) Replacement parts should be purchased from the original manufacturer or shall have qualities at least equal to the original parts.
7-2.3.4 Lubrication
(a) All moving parts of the winch for which lubrication is specified should be regularly lubricated. Lubricating systems should be checked for proper delivery of lubricant. Care should be taken to follow manufacturer’s recommendations as to points and frequency of lubrication, maintenance of lubricant levels, and types of lubricant used.
(b) Unless equipped for automatic or remote lubrication, all rotating machinery should be stopped while lubricants are being applied.
(c) Special attention shall be given to rope sections that are normally hidden during visual inspection, such as sections passing over sheaves.
(ti) Any condition resulting in appreciable loss of original strength shall be noted and a determination shall be made as to whether continued use of the rope would constitute a hazard, such as the following:
(1) reduction of rope diameter due to loss of core support or internal or external corrosion
(2) a number of broken outside wires and the degree of distribution or concentration of such broken wires
(3) worn outside wires
(4) corroded or broken wires at end connections
(5) corroded, cracked, bent, worn, or improperly applied end connections
(6) kinking, crushing, cutting, or unstranding
(c) All rope that has been idle for a period of a month or more shall be given a periodic inspection jsee (d)] by a designated person before it is placed in service. A dated report of the condition shall be filed.
7-2.4.3 Rope Replacement
(a) No precise rules can be given for determination of the exact time for rope replacement, since many variable factors are involved. Once a rope reaches any one of the specified removal criteria, it may be allowed to operate to the end of the work shift, based on the judgment of a qualified person. The rope shall be replaced after that work shift, at the end of the day, or at the latest time prior to the equipment being used by the next work shift.
(b) Removal criteria for rope replacement shall be as follows:
(1) broken wires
(a) in running ropes, six randomly distributed broken wires in six rope diameters or three broken wires in one strand in six rope diameters.
