| Electromagnetic Brake |
| Jeamar's disc-type electromagnetic brake is automatically activated in the event of a power interruption. The brake will stop the winch and hold the load securely. The brake is standard on lifting winches; optional on hauling winches. |
| Rotary Limit Switches |
| Connected directly to the winch drum, the rotary limit switch regulates the number of turns of the drum. The switch allows precise control over the amount of rope to be wound and unwound. This feature is particularly useful for repetitive applications. |
| Grooved Drums |
| In installations where space is restricted, grooved drums assist with level winding. For critical push-pull type applications, grooved drums ensure that equal diameters are maintained during winding and unwinding operations. Grooved drums also eliminate excessive rope friction. |
| Pressure Roller |
| With a grooved drum, good spooling must be maintained and the rope must be seated firmly in the grooves, a condition normally achieved by maintaining tension on the rope. When tension cannot be maintained, Jeamar offers a unique pressure roller that acts to hold the rope firmly in the grooves. |
| Free Spooling System |
| A manually operated lever clutch is available to disengage the drum, allowing the rope to be pulled out freely. The clutch is a jaw type equipped with a device to lock the clutch in the engaged position during load-pulling operations. Coupled with each free-spooling system is a drag brake that is automatically applied to stop the drum rotating once the appropriate amount of wire rope has been wound off. |
| Variable Speed and Torque Limitation |
| All Jeamar winches can be supplied with a variable frequency drive package which allows variable-speed operation when critical load placement is required. The variable frequency drive controls the amount of current the motor can draw, limiting the amount of torque the electric motor can produce, limiting the line pull as required. |
| Large Drums |
| Large-capacity drums are available for installations using greater-than-normal amounts of rope. |
| Explosion Proof |
| Fully explosion-proof motors, brakes and controls are available for applications in highly sensitive or volatile |
| Corrosion Resistance Package |
| This feature, ideal in hostile environments, protects the motor, brakes and all moving parts. |
