Winch Drums
Drums are steel fabricated and designed to specific loading capacity. Drums are sized according to ASME B30.7.2006 to provide a minimum pitch diameter of 15 times the nominal rope diameter.
Direct Drive
A simple, direct-drive design increases the efficiency of the winch and eliminates drive chains or bull gears, to maximize power output.
Any Position
An open-base design permits mounting in horizontal or vertical positions. Loads can be pulled through the base itself, which is particularly useful in limited-space installations.
All Ball & Roller Bearings
Friction load loss is reduced to a minimum through the use of ball and roller bearings. No bushings means higher efficiency and more power for pulling.
Power In - Power Out
For added safety, all winches are fully reversible. This gives the operator complete control of the winch load in both directions at all times.
Gear Reducers
All Jeamar hauling winches have high-efficiency helical gear reducers plus high-capacity, anti-friction bearings for long life, low noise and high output torque.
Electric Motors
The full range of Jeamar's heavy duty hauling winches is available with 3-phase motors in any standard voltage at 50 or 60 Hz. Winch models NHS 550, NHS 1100 and NHS 1900 are single phase in any standard voltage at 50 or 60 Hz. All motors are TEFC flange mounted and conform to NEMA, EEMAC or IEC specifications. Note that when hauling on incline, it is essential that a brake be used.
