The Model UV-25 Universal Swivel Sheave is designed
to swivel 360° and accept wire rope up to 9/16, in. (14
mm) diameter. The maximum-rated winch line pull for
underground applications is 25,000 pounds-force
(111,205 N-force); and for over head applications 14,000
pounds-force (62,000 N-force). The unit weighs 130 lbs.
(59kg).

GMP has designed and manufactured the Model
UV-25 sheave consistent with sound engineering and
manufacturing procedures. However, because of the na­ture of the product's use, extreme caution should be ex­ercised during installation and operation.
Use only the recommended mounting sockets and bolts
described on page 4 of this manual. Check each mount­ing bolt for tightness periodically depending on the
amount of use.
Make certain that the body structure to which the
sheave is to be mounted is sufficiently strong to with­stand the 25,000 pounds maximum allowable load to the
sheave.

Never load the UV-25 Swivel Sheave or the wire rope
beyond their rated capacity.
The Model UV-25 Swivel Sheave should not be used
when the required rope diameter exceeds 9/16 in.
(14mm).
Stand clear of loads suspended by the winch line. Do not
stand inside of angles formed by the winch line. As
much as possible, do not stand where there is the danger
of being struck by the wire rope if it should fail or snag.
Never place hands on a moving winch line. Always
stand clear of moving winch line. To prevent entangle­ment in moving parts and possible serious injury, do not
wear loose-fitting clothing when working around the
swivel sheave, wire rope and winch.
Wire rope (winch line) passing through the swivel
sheave may be old, damaged or weakened by such de­fects as kinks, cuts, extreme bends or loops. Such condi­tions are potentially dangerous and detrimental to safely
operating the sheave. The wire rope must be routinely
inspected at regular intervals and replaced when worn.
Make certain that the eye at the end of the winch line is
properly spliced or swaged.
It is imperative, and the responsibility of the operating
company, that the crew be properly instructed about the
safe working capabilities and operational limitations of
the sheave, the winch and especially the winch controls.
The operator should never leave his position at the con­trols while the winch line is under load.
