Product Description
GENERAL MACHINE PRODUCTS 70329 CAPSTAN DRIVE NEW Capstan Drive
Gives your mobile hydraulic equipment the capacity to
run our line of power reels and capstans. So, even when
your vehicle doesn’t have a winch, you can still afford
the benefits of GENERAL MACHINE PRODUCTS ’s highly productive cable placing
tools, like our 32 in. Torque Limiting Capstan or our
universal C.R. Reel, using this economical device.
Our Capstan Drive features a Bell standard 2-7/16 in. (62
mm) bayonet shaft and a highly efficient planetary gear
reduction that rotates on roller bearings and is powered
by a compact, continuous duty single stage motor.
At maximum flow of 15 gpm (57 l/m) and operating
pressure of 2250 psi (15 500 kPa), the capstan shaft can
achieve 58 rpm and develops 13,000 in. lbs. (1469 N-m)
of torque. That translates into the following line speeds
and line pulls:
