Heavy Duty Lifting Winch



Drums are steel fabricated and designed to specific loading capacity. Drums are sized according to ASME B30.7.94 to provide a minimum pitch diameter of 18 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.

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.

For added safety, all winches are fully reversible. This gives the operator complete control of the winch load in both directions at all times.

The full range of Jeamar's heavy duty lifting winches is available with 3-phase motors in any standard voltage at 50 or 60 Hz. Winch models NLS 400, NLS 900, NLS 1400 and NLS 2000 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.

All Jeamar heavy duty lifting winches utilize high efficiency helical worm or worm reducers.

Jeamar winches are designed and manufactured for continuous, heavy-duty operation with a minimum service factor of 1 (one).

Standard on all heavy duty lifting winches, the electromagnetic brake is a disc type that is activated automatically in the event of a power interruption. The brake will stop the winch and hold the load securely. Due to the high ratio of the worm gear, it has the effect of a secondary braking system in accordance with the requirements of OSHA.
