Inspection of crane cart track and trolley track

The large and small vehicles of the bridge crane must run on the track. In order to ensure the safety of the operating mechanism of the large and small vehicles, it is generally required to check 2 to 4 times a year. The editor will share with you the content and standards of inspection items for crane carts and trolley tracks.

The track inspection items and contents are as follows:

Check item		Check content	judgement standard
rail road	Rail	Check for cracks, sunken head, deformation, and side wear	No cracks, obvious sag, deformation and severe wear
	Rail fastening bolts	Check whether the connecting bolts are loose or fall off	No looseness and fall off
	Connecting plate and backing plate	Check whether the bolts are loose or fall off; whether the connecting plate and backing plate are shifted, defective or fall off	No looseness or fall off; no displacement, defect or fall off
	Buffer and car stop	Check for damage and misalignment; whether the installation is loose or falling off	No damage or dislocation; no loosening or falling off
	Rail joint	Check the rail joints for misalignment and gap changes	There must be no obvious dislocation and gap changes
	Rail welding installation	Check the weld for cracks and cracks	No cracks or cracks
	Geometric error	Check the deviation of gauge, track centerline, track top height, etc.	Each deviation should not exceed the specified value

According to the inspection results, necessary adjustments can be made to the track pressure plate, fish plate, bolts, etc. If it is determined that the trolley track needs to be replaced, it is not allowed to use oxygen-acetylene flame to cut the track, pressure plate or weld to prevent the deformation of the main beam caused by local heating of the upper cover plate of the main beam during flame cutting. A grinding wheel or other tools can be used to shovel the weld and disassemble the track.

To check the timely removal of the oil on the track, prevent Crane and trolley running wheel slip is now like.

The track is the basis for the smooth operation of the crane or the trolley. With the impact and vibration generated during the operation of the crane, it may cause the loosening of the track installation, the falling off of the connecting parts, the deformation, the crack, and the out-of-accuracy index. These defects in turn affect the normal operation of cranes or trolleys. Through inspection and adjustment, conditions can be provided to ensure the normal operation of the crane.
