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 GMP'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:

Device	Line Speed Ft./min. (m/min.)	Line PullLbs. (kN)

7 in. Capstan	106 (32.4)	3,250 (14.45)
C.R. Reel	304 (92.6)	1,300 (5.78)
25 in. Capstan	380 (115.7)	900* (4.00*)
32 in. Capstan	486 (148.1)	700* (3.11*)

* Line pull limited to 600 lbs. (2.76 kN) typical clutch setting

A multi-disc wet brake that's spring applied and hydraulically released is rated for the unit's full pulling load. Plus, we have designed a built-in bidirectional counterbalance valve to give you "feathering" control over the load movement in either direction.
