A potentiometer is a type of variable resistor used to measure angular position or rotation. In tower cranes, it helps monitor and control the movement of the boom, trolley, and hoist by providing accurate feedback on position and speed.
1.Precision Control：Ensures smooth and accurate positioning of loads.
2.Safety：Helps prevent overtravel, collision, and dangerous sway.
3.DurabilityBuilt to withstand harsh outdoor and industrial environments.
4.Long Service Life：Reduces downtime and maintenance costs.
1.Slewing Moton：Monitoring rotation angle of the crane.
2.Trolley Travel：Controlling horizontal movement along the boom.
3.Hoisting Mechanism：Tracking cable drum position and load height.
4.Limit Switching：Preventing mechanical overrun at extreme positions.
Based on our product specs (see image), here’s what sets our potentiometers apart:
