JAYPRO MODEL TW-800M

TorkWinch® MANUAL BACKSTOP WINCH

The basketball backstop positioning winch shall be a worm gear type designed to hold backstop at any
position when raising or lowering the backstop. The winch housing will be made of a laser cut and
formed steel designed for ease of mounting. Worm gear shall be a special self lubricating
Teflon/carbon/molybdenum composite material providing a 30 to 1 ratio. Thrust of the worm gear shall be
absorbed by hardened steel roller bearings mounted in a machined carbon steel support housing. Worm
gear shall contain a load activated uni-directional brake to prevent back driving or “creeping” down of the
backstop. Input shaft shall not extend beyond winch housing to reduce the possibility of injury from an
extended type shaft. Input shall be a 7/8" round with internal locking pin for use with a special socket
type handle provided, or with an optional (specify: JAYPRO Model ED-901 Portable electric winch
operator or Jaypro Model CD-85W Cordless operator. Winch housing must be capable of receiving and
engaging a special anti-torque safety bracket when a portable electric operator is used to reduce
possibility of injury when using an electric operator. Winch housing shall be finished with durable black
powder coat.

The cast aluminum cable storage drum shall be grooved for a 1/4" 7 x 19 aircraft cable to facilitate
smooth take-up of the cable and proper spooling of the cable. Drum shall be directly supported at the
cable-winding diameter for maximum strength and rigidity. Drum shall be supplied with a pressure roller,
with torsion spring tensioning, to ensure that the cable “tracks” in the grooves even under slack cable
conditions insuring that the cable does not spool and become frayed loosing strength.

Winch shall be provided for wall mounting with (2) 2" X 8" X 30" long yellow pine wood pad(s) for
mounting to gymnasium walls when required. Pad shall have chamfered edges and shall be finished with
two coats of natural clear gloss lacquer.

TW-800M winch shall have a two (2) year unconditional warranty on all parts and labor for defects in
material and workmanship. Any winch without this warranty does not meet these specifications and
should not be considered equal.
