Common diagnostic methods for fault handling of straight arm high-altitude work platforms

During long-term use, high-altitude work platform vehicles are inevitably prone to some malfunctions. Therefore, when we discover a malfunction in the high-altitude work platform vehicle, we must promptly diagnose and handle it.

In people's lives, the assistance and support of straight arm aerial work platform vehicles are indispensable everywhere. With the help of various straight arm high-altitude work platform vehicles, our work and life can become more warm and convenient. The straight arm aerial work platform vehicle is not a divine made perpetual motion machine, and it can also get sick and have mood problems. There are many ways to identify and find its abnormal work. The straight arm aerial work platform truck will make some noises during the operation process, and different noises reflect the real-time working conditions of various parts of the straight arm aerial work platform truck.

1. The straight arm aerial work platform truck makes a clattering sound

This sound indicates that the bearing speed of the lifting mechanism of the straight arm aerial work platform vehicle has changed, and there are ripples on the surface of the parts. Improving the appearance of the bearing raceway can reduce the occurrence of this sound.

2. The straight arm high-altitude work platform truck makes a pitter sound

This sound is composed of vibrations and collisions between the persistence device and the rolling elements. When subjected to torque, load, or large radial clearance, it is easy to produce a pitter sound. Improving the precision of the persistence device, selecting bearings with small clearance or applying preload to the bearings, reducing torque load, minimizing device errors, and selecting good smooth oil can reduce the occurrence of this sound.

3. The straight arm aerial work platform makes a buzzing sound

The buzzing sound emitted during startup or shutdown indicates that the pump station is operating without load and experiencing abnormal axial vibration. This is mainly due to the unstable vibration caused by the poor performance of shaft centering, which affects the axial vibration.
