General purpose overhead crane
Weiyuan 40 Ton Explosion-Proof Double Girder Overhead Crane
Product Overview
The Weiyuan 40 Ton Explosion-Proof Double Girder Overhead Crane is engineered for hazardous environments requiring strict ignition protection and continuous heavy-duty lifting. With a robust double-girder box structure, explosion-proof hoist and electrical system, and precise trolley/bridge drives, it provides stable handling, long-span coverage, and compliance with safety requirements in petrochemical, gas, paint, and grain-dust plants. Multiple control modes and configurable duty classes allow adaptation to different bay layouts and load cycles.
Product Advantages
- Explosion-Proof Safety Architecture
Explosion-proof hoist, motors, junction boxes, switches, and cabling; anti-spark design on moving interfaces; earthing and protective bonding for hazardous zones. - Heavy-Duty Double-Girder Structure
High rigidity and low deflection support accurate positioning at full 40 t capacity over long spans. - Smooth, Precise Motion
Matched motors and reducers for bridge/trolley; optional VFD enables soft starts, reduced swing, and finer creep speeds. - Configurable To Site Standards
Spans, lifting heights, controls (pendant, remote, cabin), power supply, and duty class tailored to process needs and local codes. - Maintainability & Documentation
Modular assemblies, clear cable routing and labeling, wiring diagrams, inspection videos, and test reports support installation and lifecycle service.
Application Scenarios
- Petrochemical & gas processing: reactor vessels, exchanger bundles, skids
- Paints, solvents, and coatings workshops: drum and tote handling
- Grain, feed, and biomass plants: combustible dust zones
- Energy, battery, and fine-chem facilities: sensitive process bays
- General hazardous areas (Zone-classified): maintenance and overhaul lifting

FAQ
1. What’s the information should I provide when inquiry?
More details or drawings, better. A: Lift capacity B: Crane arm length C: lift height: hook travel distance D: What material to lift E: power source or other specials you give us will be more appreciated.
2. How many operating methods for my selection?
Standard operating methods: A: pendent controller with push buttons .B: remote control with push buttons. Choose any type as you like.
3. Can this type work in hazardous environment?
Sure! We can customize for you, acid proof or explosion proof, no problem for that.
4. What about warranty time ?
Use within the standard for the next 12 months.
5. How can we install the crane? Our senior engineer can be your side to do the installation guide service and training.
6. 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.
