McKissick® Hoist Block, Derrick, Series: M-491S, 3/4 in Maximum Cable, 12 ton, 14 in Sheave Outside Dia, Sealed Tapered Roller Bearing, Roll Forged Sheave
- Features
| Forged steel swivels, tees, yokes and shackles are quenched and tempered |
| Sheave lubrication through center pin for easy maintenance |
| Recessed side plate design reduces the gap between the sheave rim and the side plate, allowing the sheave assembly to be captured in the block if loss of center pin occurs |
| Sealed tapered roller bearings extend the life of the center pin and bearings and allows for faster line speeds than recommended with standard snatch blocks |
| Shackle fitting swivels for easy positioning |
| Suitable for hoisting personnel, contingent upon all employees, including the winch operator, being trained to follow applicable federal, local and industry standards |
| All blocks 14 in and larger are furnished with McKissick® roll forged sheaves with flame hardened grooves |
