The BMG semi-gantry crane is composed of double main beams, an electric trolley and single-side supporting legs. Its unique structural design enables one side of the crane to anchor onto building walls or structural columns, while the other side is supported by standalone gantry legs. This layout maximizes on-site space utilization. The main beam adopts an integral box welded structure, and the travelling mechanism is equipped with independent driving units.
This semi-gantry model supports three operational modes: ground handle control, wireless remote control and cabin operation. It offers two optional power supply methods, including cable reel and sliding contact wire. With flexible structural layout, the crane covers a larger working range and delivers efficient material handling capabilities for space-limited sites.
It is widely applicable for cargo loading, unloading and transshipment at mining yards, railway freight stations and open-air warehouses. Compatible with multiple auxiliary lifting devices, it can complete various special hoisting tasks.
Equipped with contactless modular speed regulation technology, the crane supports micro-speed and dual-speed operation. Both travelling and lifting movements run extremely smoothly, with simplified electric control logic that delivers performance close to variable frequency systems. The control handle adopts 12V and 380V dual voltage design for flexible adaptation.
Ideal for industrial plant deployment, the crane excels at hoisting heavy machinery and equipment components, especially in narrow and confined working areas. It also serves as an efficient handling solution for cargo loading, unloading and stacking in logistics warehouses.
Built with box-type double beams and π-shaped welded support legs, the whole structure features high rigidity and superior operational stability compared with conventional designs.
Two flexible power supply modes are available: cable reel and sliding contact wire, providing diversified options to match different site conditions.
The electric trolley adopts special-shaped steel rail power supply cables, effectively improving overall hoisting stability and working performance.
Centralized mechanical and electrical control is realized in the operating cabin, making daily operation more convenient and flexible with simplified control procedures.
