The overhead travelling crane safety

The overhead travelling crane safety: A overhead travelling crane safety is a trolley running on a beam rail, lifting heavy objects is carried out on one side of the main girder, weight will produce a rollover torque for overhead travelling crane trolley.  A vertical against the rail wheel or level and the rail wheel to produce resistance to overturning moment makes the trolley balance, not tilting. However, only in this way can’t guarantee in the storm, outside impact, wheel broken, etc. under the condition of safety maintenance. Therefore, this type of crane shall be installed with safety clasp. Safety clasp, according to the trolley wheel and rail type is different, also designed different structure.

In the process of overhead travelling crane safety use safety clasp need to pay attention to maintenance inspection, so as not to affect the normal work of the safety clasp.

1. Safety buckle in rail gap should comply with the design requirements.

2. Bolts should be no loose, dislocation, weld cracking, safety buckle no abnormal deformation and damage.

3. When the small trolley along the girder span runs, safety clasp between rail and web girder can't have any jam, blow grind web phenomena occur.

4. Inspection, should test to function as the basic method, visual analysis and operation test.
