MHB Semi-Gantry Crane Performance
Equipment Description
Structural form: One side of the gantry features a leg (running along ground tracks), while the other side is legless (supported by overhead plant rails), maximizing space utilization; the gantry can adopt a box-type structure (superior craftsmanship, easy fabrication, excellent rigidity) or a truss structure (lightweight, low wind resistance, outstanding wind resistance), adapting to various working environments.
Control & power supply: Supports ground pendant control, wireless remote control, centralized cab control, and other modes; power is supplied via cable reels or overhead sliding lines, enabling efficient "load lifting - horizontal transfer" full-process operations.
Application Fields
Industrial manufacturing: Material handling and equipment installation in general machinery/assembly workshops, new energy equipment plants (e.g., wind/solar component production);
Warehouse logistics: Loading/unloading and stacking of medium-small cargo (components, bulk materials) in warehouses, railway freight yards, and port terminals;
Construction projects: Component hoisting at hydropower stations or construction sites (where one side has plant/high-rise structures), and auxiliary material transfer for subway/tunnel projects;
Usage restrictions: Not suitable for flammable/explosive environments, high-humidity corrosive atmospheres, or scenarios involving molten metal/toxic/flammable materials.
Product Advantages
The single-leg + overhead rail design leverages existing structures, reducing track width by ~30%, suitable for narrow workshops and "building-open air" transitional sites, significantly lowering rail installation investments.
Smart & efficient, precise operation
Standard wireless remote + variable frequency speed control enables lifting speeds up to 12m/min with <5mm positioning accuracy; single-operator capability for complex lifts; some models feature inch movement, micro-speed, zero-speed suspension, and anti-sway functions, improving precision and efficiency (e.g., 40% faster material alignment).
Multi-scenario + multi-attachments, versatile machine
Lifting capacity 1t–20t, span 3m–30m, lift height 3m–30m, duty class A3–A5; optional grabs/electromagnetic attachments for handling steel, bulk goods, timber, etc., meeting industrial/logistics/construction needs.
Safe & reliable, easy maintenance
Equipped with overload protection, travel limiters, anti-derailment devices; modular design (e.g., main/end beams connected by 10.9-grade high-strength bolts) for easy disassembly; integrated lifting/traveling mechanisms (e.g., "motor + brake + gearbox" combo drive) reduce maintenance needs and labor costs.
Eco-friendly, lightweight & energy-saving
More economical than full-gantry cranes in procurement/operation; truss gantry offers lightweight/low wind resistance; box-type gantry features mature craftsmanship; electric drives produce no emissions/low noise; some models use lightweight materials and energy-saving controls (e.g., Schneider VFDs), aligning with green production trends.
