Overhead crane end truck
 The  installation of end truck (also called end carriage) in the crane is a very  special and important part, which is used to support the bridge to maximize the  stability of the overhead crane (bridge crane), It is made of new innovation  material of Q235B steel.
 The  end truck for overhead crane is very important. It is responsible for load  shifting in operation and is a key part of the whole overhead crane. Wheels and  end beams are part of it. The upper cover plate, the web and the lower cover  plate comprise of the end beam, which has a connecting plate and an angle steel  for reinforcement. The internal installation of the overhead crane's end frame  should be strengthened to improve the stability of the end beam. In the design  of overhead traveling crane, the size of the end truck should be designed  according to the size of the main girder, wheelbase and wheelbase of the trolley.  When carrying out the installation of overhead cranes, the end truck are  usually connected to the main girder and then connected to the connecting points  of both ends of the beam.


As  an important force component of the overhead crane, the crane end truck can  gnaw the rail due to its manufacture, installation and  improper operation. It needs to be maintained regularly during use.
 Common  crane end truck (end carriages) problems
 The  main reason for the wheel gnawing is the deformation of the end truck. Once the  end truck is deformed in the horizontal section, crane bridge will deflect  during the operation. The main beam and end frame will weld joint in the  manufacturing, which will relieve the deflection degree. The principle is that  the main beam of the weld is connected more. When the overhead crane is  installed and welded, the end truck will bend outward because of the uneven  force, reducing the deflection phenomenon.
 The  increase plate can be used when making the end frame, and its purpose is to  increase the rigidity of the wheel installation position. In the dusty  environment, there is a gap between the wheel and the machine, and the  maintenance work is not in place, environment as high humidity or corrosive gas  may corrode the plywood, If the plate thickness continues to decrease, the  wheel will be skewed when running, resulting in serious rail biting.
