Gantry crane
Weiyuan Heavy Duty MG Type Crane for Extreme Weather & All-Environment Safety

Product Overview
The Weiyuan Heavy Duty MG Type Gantry Crane is built with safety, structural resilience, and complete environmental protection as its core engineering priorities. Operating outdoors exposes lifting equipment to harsh weather including heavy rain, snow, salt mist, and sudden gale-force winds. The Weiyuan MG Crane addresses these risks through an IP55-rated electrical enclosure system, multi-layer marine-grade anti-corrosion paint, and comprehensive electronic and mechanical safeguards. Featuring integrated wind anemometers, hydraulic rail clamping systems, electronic anti-sway control, and overload limiters, this crane ensures zero-accident operation in high-risk outdoor worksites.
Product Advantages
Engineered for Outside Lifting: Built with weather-sealed IP55/IP65 electrical enclosures and protective rain covers for motors/brakes to prevent water, salt, and dust ingress.
Heavy-Duty Lifting Power: Integrated electronic anti-sway control provides VFD-driven smooth acceleration and deceleration, significantly reducing load swing for ground personnel.
Superior Stability and Reach: Features multi-tier wind anchoring including real-time anemometers, hydraulic rail clamps, and manual locking pins to secure the crane against storm winds.
Durable and Low-Maintenance: High-precision electronic overload limiters and dual-stage limit switches prevent structural over-stress and rail over-travel.
Customized to Your Needs: Shot-blasted steel (Sa2.5 grade) coated with epoxy zinc-rich primer and polyurethane topcoats ensures long-term resistance against rust and UV degradation.
Application Scenarios
Outdoor Stockyards: Designed for high-wind open material stockyards subject to sudden storm conditions and heavy wind exposure.
Precast Concrete Facilities: Ensures continuous casting yard loading operations regardless of rain, snow, or seasonal storms.
Heavy Industrial Plants: Operates reliably across ambient temperatures from -25°C to +40°C in mining and extraction environments.
Stone and Quarry Industry: Handles heavy stone blocks with high safety margins and automatic load monitoring in dusty environments.
Construction Sites & Ports: Ideal for coastal docks and ports requiring resistance against aggressive salt spray, humidity, and high sea winds.

FAQ
- What’s the information should I provide when inquiry?
More details or drawings, better. A: Lift capacity B: Crane arm length C: Lift height D: What material to lift E: Weather/site conditions (e.g., wind speed, coastal area, temp range). - How many operating methods for my selection?
Standard operating methods: A: Pendent controller with push buttons .B: Remote control with emergency stop. C: Enclosed cabin with safety glass. Choose any type as you like. - Can this type work in hazardous environment?
Sure! We can customize for you, acid proof, explosion proof, or extreme storm-resistant configurations, no problem for that. - What about warranty time ?
Use within the standard for the next 12 months. - How can we install the crane?
Our senior engineer can be your side to do the installation guide service, safety testing, and operator training. - May I visit your factory?
Of course. We can pick you up at train station, high-speed rail station or airport, and book hotel for you.
