Crane end carriage is one of the important components of the crane structure. It is part of the crane bridge system. Its main function is to carry the crane's traveling mechanism and support the overall operation of the crane. Crane end carriage bears the load of the entire crane bridge system, the weight of the crane itself and the weight of the load. It has sufficient carrying capacity and stability to ensure that the crane will not be deformed or damaged during operation. This crane end carriage cooperates with the track and wheel system, so that the crane can run smoothly and accurately along the track. Its design must ensure good contact between the wheel and the track. It supports the crane's power drive system and control system. During operation, the crane's traveling mechanism, drive motor and other equipment are fixed on the end beam. Some protective structures are designed on the end beam to protect the crane's internal electrical system, mechanical system, etc. from external environmental influences.
