Weiyuan Heavy Duty MG Type Gantry Crane with Storm Protection & Fail-Safe Safety Systems

Product Overview
The Weiyuan Heavy Duty MG Type Gantry Crane is designed to maintain structural stability and operator safety under severe outdoor weather conditions. Operating a large gantry crane outdoors presents risks from sudden wind gusts, rainstorms, and heavy cyclic loading. The Weiyuan MG Crane addresses these hazards with a mechanical and electrical safety package: digital wind anemometers that automatically interlock with travel drives, hydraulic rail clamping mechanisms, manual storm anchor pins, and electronic overload protection. Built with rigid Q355B steel box girders and IP55 weatherproof components, this crane provides stable, controlled lifting in high-wind regions, coastal ports, and demanding industrial yards.
Product Advantages
Engineered for Outside Lifting: Equipped with motor rain covers, enclosed cable reels, IP55 electrical enclosures, and marine-grade anti-corrosion paint to handle rain, humidity, and temperature shifts.
Heavy-Duty Lifting Power: Dual main box girders and high-torque winch drives provide steady hoisting power, preventing load drift during high-tonnage lifting operations.
Superior Stability and Reach: Incorporates an automatic anti-wind protection package: when wind speeds exceed safe limits (e.g. 12 m/s), an audible alarm sounds and hydraulic rail clamps lock the crane directly to the rails.
Durable and Low-Maintenance: High-strength forged steel components, dual-stage limit switches, and polyurethane travel buffers protect structural welds and mechanical drives from impact damage.
Customized to Your Needs: Weiyuan tailors the crane’s wind-load design calculations, braking torque, foundation anchor points, and control systems to meet local seismic and environmental building codes.
Application Scenarios
Outdoor Stockyards: Provides safe material handling in open, wind-exposed storage yards for steel profiles, plates, and pipes.
Precast Concrete Facilities: Safely lifts and positions long, heavy concrete beams and panels with minimal wind-induced load swing.
Heavy Industrial Plants: Operates safely near coastal or high-wind industrial zones, moving large machinery assemblies between outdoor bays.
Stone and Quarry Industry: Reliably handles heavy stone blocks in dusty, open quarry environments with continuous overload monitoring.
Construction Sites: Delivers dependable lifting for structural steel frames, rebars, and heavy precast units on major infrastructure job sites.
