Drums are steel fabricated and designed to specific loading capacity. Drums are sized according to ASME B30.7.2007 to provide a minimum pitch diameter of 15 times the nominal rope diameter.
A simple, direct-drive design increases the efficiency of the winch and eliminates drive chains or bull gears to maximize power output.
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.
HIGH SERVICE FACTORS
Jeamar winches are designed and manufactured for continuous, heavy-duty operation with a minimum service factor of 1 (one).
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.
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.

When a hauling winch is used to move loads on an incline, it is essential that a brake be used.
