Single girder overhead crane end beam
| Quantity: | |
|---|---|
The end beam of a single-girder crane is the core load-bearing and traveling component of the single-girder crane. It connects the main beam and the operating mechanism, directly determining the overall operating stability and safety performance of the equipment. It is widely applicable to various industrial crane scenarios.
