| 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 18 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. |
| 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. Single phase units are available on loads up to 2000 lbs. All motors are TEFC flange mounted and confrom to NEMA, EEMAC or IEC specifications. |
| Gear Reducers |
| All Jeamar lifting winches utilize high-efficiency helical worm or worm gear reducers plus high-capacity, anti-friction bearings for long life, low noise and high output torque. |
| 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. |
