Zhongyuan Heavy Industry: Causes of Abnormal Heating in Crane Motors

Through long-term experience, Zhongyuan Heavy Industry has found that prolonged overheating of crane motors significantly reduces the lifespan of cranes and may lead to a series of operational failures, even causing accidents. Therefore, timely control and protection against motor overheating are crucial. Below, Henan Zhongyuan Heavy Equipment Co., Ltd. will explain the causes of abnormal motor overheating.

If the cranes manufactured by Zhongyuan Heavy Equipment are used too frequently, the motors are prone to overheating. This is especially true during frequent start-stop operations, which often leave the crane in a state of starting, braking, and reversing. The load becomes unstable, fluctuating between heavy and light, and the motor frequently endures significant impact forces, often leading to overload conditions. Zhongyuan Heavy Equipment reminds everyone that during crane startup, excessive current causes power losses much greater than those during rated-speed operation. Additionally, the heat dissipation coefficient decreases at this time, leading to a sharp rise in motor temperature with multiple startups. Moreover, during high summer temperatures, the temperature difference inside and outside the motor is small, resulting in poor heat dissipation. Prolonged operation under these conditions makes motor overheating more likely.

Henan Zhongyuan Heavy Equipment Co., Ltd. believes that crane motor overheating is closely related to usage frequency. Therefore, after a period of operation, timely heat dissipation work should be performed to ensure the equipment operates in a better state for ** operations.
