The performance of the winch shall be tested using the following procedures. Lubricate the winch. The winch shall be bolted to a sui

40、table foundation. The test load shall cause a minimum line pull as specified in table I. The line pull shall remain constant for a length of at least 30 ft. With the ratchet mechanism engaged, the load shall be winched for 30 ft and then the crank(s) shall be released. The effort required shall not

41、exceed 25 lbs per crank. No playout of the line is allowed. The handbrake shall be engaged and the ratchet shall be released. Using the handbrake only, controlled playout of the line shall be allowed, stopping and holding the load at approximately 5 ft increments for a total of 30 ft. This procedure

42、 shall be repeated for a total of 15 cycles. One cycle of the test shall be completed except the load shall be winched to within 5 ft of the winch so that the drum is spooled to capacity (input force on the crank(s) may exceed 25 lbs). Any evidence of damage, operating difficulties, or malfunctions

43、shall constitute failure of this test. 5. PACKAGING 5.1 Packaging. For acquisition purposes, the packaging requirements shall be as specified in the contract or order (see 6.2).
