General purpose overhead crane

Product Overview
The Weiyuan Heavy Duty QD Hook Overhead Crane is designed for facilities where lifting safety, load control, and equipment protection are critical. Operating heavy loads overhead inside crowded workshops requires dependable mechanical brakes, accurate speed regulation, and reliable safety interlocks. The Weiyuan QD Crane incorporates a complete multi-layer safety package: electronic overload sensors with automatic cut-offs, dual-stage travel limit switches, fail-safe electromagnetic/hydraulic brakes, and Variable Frequency Drive (VFD) anti-sway controls. This ensures stable, shock-free lifting and micro-positioning over active assembly lines and valuable plant machinery.

Product Advantages
Engineered for Workshop Productivity: Smooth acceleration ramps and electronic sway suppression eliminate load pendulum motion, protecting ground personnel and machinery.
Heavy-Duty Lifting Power: Dual mechanical braking on the hoisting mechanism ensures immediate, positive load holding without drift during power cuts or emergency stops.
Superior Stability and Reach: Precise micro-speed control (down to 0.1 m/min) allows operators to gently mate heavy components, mold dies, and machine parts without impact.
Durable and Low-Maintenance: High-grade Q355B steel plate, heavy-duty forged hooks with safety latches, and polyurethane travel buffers absorb mechanical shocks.
Customized to Your Needs: We configure safety limits, cabin visibility angles, wireless remote interlocks, and warning alarm systems to match your plant’s EHS protocols.

Application Scenarios
Mold & Tooling Workshops: Delivers delicate micro-inching to align, separate, and position injection molds and stamping dies without damaging guide pins.
Precision Assembly Lines: Safely lowers heavy sub-assemblies into tight machine frames without sudden jerks or load swinging.
Steel Coil Warehouses: Transports heavy coils smoothly across storage bays without load slippage or dynamic runway shocks.
Maintenance & Repair Bays: Accurately positions heavy replacement rotors, bearings, and housings during plant equipment overhauls.
Foundry Casting Transfer: Provides dependable dual-brake holding and thermal shielding for moving hot castings and heavy molds safely.
