OPERATING THE WINCH

TM 9-2320-273-10

OPERATING THE WINCH

Do not pull up on control no. 2. This position is for

operating equipment that is not used on the M915

series vehicles.

CAUTION

Observe the drum to ensure that the wire rope is not

completely paid out. Never operate the winch with less

than four turns of line on the drum.

NOTE

The rated winch pull is set by limiting the hydraulic

system relief valve pressure to a maximum of 2100 psi

which provides 45,000 lb (20,250 kg) pull on the bare

drum. As the winch drum is loaded with line, the

effective line pull is reduced. The line pull per cable

layer with 7/8-inch wire rope is:

1st layer 45,000 lb (20,250 kg)

2nd layer 39,265 lb (17,810 kg)

3rd layer 34,775 lb (15,773 kg)

4th layer 31,210 lb (14,156 kg)

5th layer 28,310 lb (12,841 kg)

a. Lower pusher axle.

b. Have a crew member disconnect the wire rope clevis from its anchor.

c. Pull up on winch control lever no. 2 to the middle position

d. To pay out the line, pull up and hold the winch control lever no. 1 in the full up

position. The winch will unwind in low speed. Have your crew member walk the

end of the wire rope out.
