Our Winch 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 18 times the nominal rope diameter.
Electric Motors
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.
Braking Systems
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.
