| 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 15 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. |
| Ball & Roller Bearings Throughout |
| 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. |
| Gear Reducers |
| All Jeamar air winches have high-efficiency helical reducers plus high-capacity, anti-friction bearings for long life, low noise and high output torque. Totally enclosed reducers make them weatherproof. |
| Air Motors |
| Jeamar air motors are fully reversible vane type. Positive starting and precise control are central features of the motors, which have been designed for long life and low-cost operation. They can be stalled indefinitely under load without harm to the motor. Note that when moving loads on an incline, it is essential that a brake be used. |
| Control Valve |
| Control valves feature proportional flow with spring return to neutral for "deadman" operation. Valves control the winch speed by varying air flow to the motor. With the control released, air flow is cut off, stopping the winch. Controls are supplied loose to allow for mounting that is appropriate to the application. *Load Calculations: For detail on pulling railcars or pulling up grades, please call or emailus and we will gladly work with you in providing the best solution. |
