General purpose overhead crane

Product Overview
Safety, operational precision, and asset protection are the foundational pillars of the Weiyuan QD Hook Double Girder Overhead Crane. Operating heavy machinery overhead inside a busy workshop requires zero tolerance for operational error. The Weiyuan QD Crane incorporates a comprehensive multi-layer safety barrier, combining electronic overload protection, dual-stage travel limit switches, emergency stop circuits, and heavy polyurethane buffers. Featuring intelligent VFD controls and optional electronic anti-sway algorithms, this crane prevents load swinging, protecting factory personnel, floor machinery, and valuable loads during every move.

Product Advantages
Comprehensive Mechanical & Electrical Protection: Equipped with high-precision load cell overload limiters, dual-stage travel switches, and emergency stop systems to prevent structural over-stress.
Electronic Anti-Sway Precision Control: VFD stepless speed controls and sway suppression algorithms minimize load pendulum motion, ensuring smooth transport over active workspaces.
Fail-Safe Dual Braking System: Open winch trolley mechanisms feature heavy-duty disc or block brakes that automatically engage upon power interruption to hold loads securely.
Ergonomic & Clear-Vision Operation: Air-conditioned cabins with safety glass and ergonomic joysticks or handheld wireless remotes ensure clear operator line-of-sight.
Durable Electrical Architecture: Siemens/Schneider electrical components housed in dust-proof IP54/IP55 control panels guarantee reliable, fault-free signaling.

Application Scenarios
High-Density Assembly Workshops: Safely transports heavy parts over active assembly lines without risking sway damage to ground equipment.
Mold & Stamping Facilities: Precision micro-speed control enables exact die alignment during mold changing operations.
Steel & Coil Warehouses: Smooth acceleration and braking prevent heavy steel coils from slipping or shifting during cross-bay transport.
Foundry & Casting Bays: Reliable dual brakes and thermal shielding protect personnel during hot metal or heavy casting transfers.
Maintenance & Service Bays: Accurately positions heavy replacement parts into tight machine tolerances during plant overhauls.

FAQ

1. What’s the information should I provide when inquiry?
   More details or drawings, better. A: Lift capacity B: Crane span C: Lift height D: Material to lift E: Specific safety requirements (e.g., anti-sway, dual brakes, cabin type).
2. How many operating methods for my selection?
   Standard operating methods: A: Pendent controller B: Wireless remote with emergency stop. C: Ergonomic cabin control. Choose any type as you like.
3. How does the anti-sway system improve workshop safety?
   The VFD anti-sway system controls acceleration and deceleration ramps to eliminate load swinging, allowing safe movement over floor equipment and workers.
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, safety system commissioning, and operator 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.
