SL type manual single-girder crane

The SL type manual single-girder crane is a type of overhead crane that achieves lifting and horizontal movement of goods through manual operation. It is an industrial equipment for material handling driven by human power, suitable for work scenarios without power supply or with light loads.

Structural Composition

The structure of the SL type manual single-girder crane mainly includes the following parts:

• Bridge: This is the main structure of the crane, typically composed of a main girder and end carriages. The entire machine operates suspended from the lower flange of an I-beam rail.
• Crane Travel Mechanism: The component that drives the entire crane to move longitudinally along the workshop rails.
• Manual Trolley and Hand Chain Hoist: The manual trolley is installed on the main girder and is driven by a manual chain to achieve lateral movement. The hand chain hoist is responsible for the final lifting operation; the two work together to complete the three-dimensional movement of heavy objects.

Its working principle is very direct: All actions, including the longitudinal movement of the crane, the lateral movement of the trolley, and the lifting/lowering of the load, are achieved entirely by the operator pulling the chains.
