The QDX Lightweight Double Beam Bridge Crane, (also know as the European-style bridge crane) features a compact structure and lightweight design, which can effectively reduce building headroom requirements and wheel pressure, its overall weight is approximately 15-30% lighter than traditional cranes, offering high efficiency and energy saving, while enabling precise lifting in limited spaces.

Technical Parameters

Lifting capacity	Generally 5-100t; Maximum tonnage limited by lightweight design.
Lifting height	The vertical distance from the lowest position to the highest position of the hook. The common lifting height is 12~20m.
Span	10-35m; Design shall be strengthened for large span;
Working level	A5-A6; Suitable for medium and high frequency operation;
Lifting speed	0.5~15 m/min (frequency conversion); Low-speed precision/high-speed no-load;
Control mode	Remote control+cab (optional); Support IoT remote monitoring;
Voltage	Non-standard customization.

LOW HEADROOM OVERHEAD CRANT PARTS

Compact Structure: Optimized cross-sections of the main and end beams reduce self-weight while enhancing headroom utilization for improved efficiency.
Optimized Space Utilization: Offset arrangement and side-mounted electric hoist design, increase lifting height and save valuable plant headroom.
Low Wheel Pressure: Strategic wheel load distribution and stiffness adjustments significantly lower wheel pressure, minimizing wear on plant floor/tracks and reducing foundation costs.
Increase overall handling capacity: Boost material handling throughput(tied to load capacity of 1-20 tons and efficient operation in restricted areas for better workflow).

European modular components

European modular components

Three-in-one drive motor (motor+brake+reducer integration) and maintenance-free wheel set are adopted, with low failure rate.
Intelligent expansion

Capable of integrating PLC control, anti-rolling system and automatic positioning, compatible with intelligent plant requirements
Energy conservation and environmental protection

The energy consumption is 15% - 20% lower than that of the traditional crane, and the noise is ≤ 75dB
