LD Single Girder Bridge Crane

The electric hoist single girder crane is a lightweight rail-operated lifting equipment, mainly composed of an electric hoist (the core lifting mechanism for vertical movement of loads), a metal structure (the main girder typically uses I-beam steel or a combination of steel beams and plates, with end beams and other components welded/assembled for a compact overall structure), a trolley traveling mechanism (often separately driven, paired with conical motor braking, open gear transmission, with optional soft-start motors or variable frequency speed control devices for smooth starting and safe operation), a power supply device (providing electricity to the equipment), and an electrical device (integrated control and protection functions). The lifting trolley, with the electric hoist as its core, travels horizontally along the I-beam steel main girder, enabling 'vertical lifting + horizontal movement' load handling operations within the workspace. Operation modes include ground pendant control, wireless remote control, and cabin operation (with separate open or enclosed cab options), flexibly adapting to various work scenarios.
