Description
BMG semi gantry crane consists of two main beams, an electric trolley, and a supporting leg on one side. This design allows one end of the crane to be fixed to a building wall, column or other structure, while the other end is supported by independent legs. Adopting this structure of gantry crane can fully utilize the site space. The main beam adopts a box-welded structure, and the large vehicle operating mechanism is driven separately. Semi-gantry crane operation includes ground operation, remote control operation, and cabin operation.
There are two conductive forms of semi-gantry cranes: cables and sliding contact wires. Such a structure allows the semi-gantry crane to cover a larger working area and provide an efficient material handling solution in limited spaces.

Advantages
When purchasing a marine travel lift for sale, it is recommended to conduct a professional evaluation in the following four areas:
Space-Saving Asymmetric Design
One end of the crane mounts directly to an existing building column or wall bracket, while the other runs on a ground-level rail . This eliminates the need for a full portal structure, saves valuable floor space, and reduces civil foundation costs .
Heavy Load Capacity & Structural Rigidity
The double-girder box-section structure provides exceptional bending and torsional rigidity, with lifting capacities ranging from 5 up to 320 tons . FEA-verified design ensures deflection stays within L/1000 under full rated load, delivering stability even under demanding conditions .
Versatile Operation & Precision Control
The crane supports ground pendant, wireless remote, and cabin operation . Equipped with variable frequency drive (VFD) technology and inverter-controlled hoisting, it enables smooth start/stop, precise positioning (up to ±10 mm), and optional features like micro-speed and electronic anti-sway for accurate load handling .
Robust Construction for Continuous Duty
Engineered for work duty classes A5 to A7, the BMG crane is built for intermittent to intensive production cycles . High-tensile steel construction, shot-blasted and epoxy-primed for corrosion resistance, ensures a service life exceeding 20 years&
