How to keep balance for goliath crane travelling?

Stable crane travelling is related to the compact design of equipment parts, especially the design of supporting legs. Supporting leg is an important part of the crane. The part that the legs connect with main girder is within the scope of plane of crane frame and legs. If the leg can’t move smoothly, it mainly shows as following, the leg is out of shape, the top of the leg backwards or move in synthetic lateral direction. To keep the crane travel in stable, these two factors must be strengthened.

First is the connection of legs and main girder. Four rigid legs and two flexible legs are in need. They are used to balance the crane and trolley’s braking force.

The constraining force of leg end is also essential for stable travelling. If the leg’s pressure approaches critical state, the legs becomes out of balance, thus the leg’s rigid and flexible degree is very strict.

How to reduce noise of goliath gantry crane?

In general, there are three factors those cause the noise. First is the parts friction noise. This is mainly caused by processing error. Related parts impact, frit and make noise during work. Second, too much pressure leads noise. The crane relies on the cone valve’s vibration to rotate, the cone valve’s vibration relies on pilot valve cavity pressure before beating. Once the pressure is not stable, it can lead noise. Third, hydraulic impact makes noise. It is the energy source of system vibration. Once mechanical parts resonant, this can lead too powerful hydraulic impact and noise.

The workers grasp basic information and knowledge about the crane system, the crane is equipped with controlling system, these can help reduce noise.
