1.2.4.1 

If the direction of the wire rope is not indicated on the winch, determine as follows: 
Engage the locking pawl and disengage the brake system. Rotate the winch drum using 
either the handwheel or hand ratchet. The only allowable direction for the drum to rotate is to 
reel in the wire rope onto the drum at the bottom.

1.2.5 

Check to ensure that there is enough clearance between winch drum and mounting surface. Check 
to make sure there is enough clearance for proper operation of the handwheel and FASST Winder

. 

Rotate the FASST Winder

 back and forth checking for clearance issues (see fig. #2).

1.2.6 

Maintain a fleet angle no greater than 1-1/2 degrees from winch drum to lead sheave (see appendix 
5). The proper fleet angle helps to minimize wire rope damage by assisting the wire rope to wind 
uniformly onto the drum.

1.2.7 

Using sufficient tack welds, secure the base bars to the deck or doubler plate. This will prevent the 
winch from becoming misaligned from heat distortion during the application of the seal weld.

1.2.8 

Next apply a seal weld to the mounting fixture to permanently secure it to the deck. The seal weld will 
prevent corrosion from occurring between the mounting fixture and mounting surface.

1.2.9 

Inspect the winch immediately following installation. This inspection will give a good starting record of 
the winch condition so that future inspections can be compared.

CAUTION

Remember that the weld has to be strong enough to withstand loads equal to or greater than 

the capacity of the winch and ultimate capacity of the wire.
