Fault Diagnosis Method for Telescopic Boom Crane with High Working Platform

The articulated boom lift platform vehicle emits some sounds during operation, with different noises reflecting the real-time working conditions of various parts of the articulated boom lift platform vehicle. To be more specific:

1. The telescopic boom高空work platform emits a clattering sound.

This noise highlights a change in the bearing rotational speed of the lifting mechanism in the telescopic boom lift, as well as surface ripple on the parts. Improving the surface condition of the bearing raceways can reduce the occurrence of this noise.

2. The articulated boom lift platform emits a dripping sound. This sound is caused by the vibration and impact of the holder and the roller. When subjected to torque, load, or a large radial clearance, a dripping noise is more likely to occur. To reduce this sound, improving the precision of the holder, using bearings with smaller clearances, applying pre-load to the bearings, reducing torque and load, minimizing installation errors, and using high-quality lubricating oil can be effective.

3. The telescopic boom lift emits a humming sound.

The humming sound during startup or shutdown indicates that the pumping station is operating without load. However, the station is experiencing abnormal axial vibration, which is primarily an unstable vibration caused by the influence on axial vibration when the shaft alignment performance is poor.
