Ramsey Winch SCH-4900 - Manual (Page 4)

WARNINGS:
STAY OUT FROM UNDER AND AWAY FROM RAISED LOADS.
STAND CLEAR OF CABLE WHILE PULLING. DO NOT TRY TO GUIDE CABLE.
DO NOT EXCEED MAXIMUM LINE PULL RATINGS SHOWN IN TABLE.
DO NOT USE WINCH TO LIFT, SUPPORT, OR OTHERWISE TRANSPORT PERSONNEL.
A MINIMUM OF 5 WRAPS OF WIRE ROPE AROUND DRUM BARREL IS REQUIRED TO HOLD THE LOAD.
WINCH MOUNTING
NOTE: The winch must be mounted so that the cable reels in in the required direction as noted on page 6.
NOTE: Remove and discard the (4) 1/2” capscrews from the foot mounting holes in the end bearings.
These capscrews hold on the foot mount spacers during shipping and should not be used for mounting.
It is most important that this winch be mounted securely so that the three major sections (the motor end, the cable
drum, and the gear-housing end) are properly aligned. Excessive bushing wear is a symptom of misalignment.
When installed mid-mounted, at least one tie plate should be attached to the mounting feet at the bottom of the winch
to maintain alignment. When installed foot-mounted, at least one tie plate should remain mounted at mid point of
winch to maintain alignment. It is always preferable to use both tie plates in the installed configuration.
When mounting the winch, the mounting hole patterns described on page 6 should be used. The mounting surface
must be flat within 0.015 inch and sufficiently stiff to resist flexing. If a steel plate is used for foot mounting it should
be .750 inch thick. For this mounting application eight (8) 1/2-13NC x 2-1/4” Lg. Gr. 5 capscrews with lockwashers
will be needed to mount winch. Note that the supplied foot-mount spacers (.88” thick) must be installed between the
winch and the mounting plate. Capscrews should be torqued to 85 ft-lb. (115 Nm).
CAUTION: IF LONGER BOLTS ARE SUBSTITUTED TO MOUNT WINCH OR TO MOUNT A ROLLER GUIDE AT
THE SIDE MOUNT PADS, GRADE 5 OR BETTER BOLTS SHOULD ALWAYS BE USED, AND BOLT LENGTH
SHOULD BE SUCH THAT A MAXIMUM OF .56 INCH THREAD LENGTH ENGAGEMENT IS ACHIEVED IN THE
TAPPED HOLES IN THE SIDES OF EACH END BEARING.
