QDX European-style double-girder overhead crane
Equipment Description
The drive system often employs a **"three-in-one" drive unit** (integrating motor, reducer, and brake, featuring hardened gear surfaces for high transmission efficiency). The electrical system incorporates variable frequency speed control technology, enabling independent control of lifting, trolley, and other mechanisms for smooth, stepless speed adjustment. It also supports remote operation and smart monitoring (e.g., operational status, fault alerts). Some models are equipped with cadmium-plated slide rails, anti-vibration contactors, and other components to further enhance operational stability and durability.
Application Fields
Factory workshops (e.g., steel plants, machinery plants, plastic plants): Handling heavy machinery components, raw materials, and assembly line workflows.
Warehousing/logistics centers or ports/terminals: Stacking and loading/unloading goods, as well as cross-regional transportation of containers, coal, ores, and other bulk commodities.
Construction engineering/rail transit sectors: Hoisting and installing prefabricated components (e.g., bridge girders) and rail equipment.
Cleanroom facilities and smart workshops: Maximizing limited space for automated, precision production needs (e.g., precision instrument assembly workshops).
Product Advantages
Low self-weight and wheel pressure (approximately 30% lower than traditional cranes), with minimal hook-to-ground/wall clearance and reduced headroom requirements. This expands operational space in existing facilities (increasing lifting height) while reducing building height and material costs for new facilities.
Energy-efficient and smoother operation
Variable frequency speed control ensures gentle starts (reducing impact loads on equipment and materials), with low overall power consumption and significant energy savings. The "three-in-one" drive and other high-efficiency transmission designs minimize energy loss, reduce noise, and align with green production standards.
Smart precision with comprehensive safety
Advanced electrical systems support remote/automated control and precise positioning (minimal repetitive errors). Some models integrate anti-sway hooks and dual brakes, along with overload protection, anti-tip devices, and phase-loss protection for full operational safety.
Easy maintenance, lower lifecycle costs
High-quality standardized components (e.g., Class F insulation, IP54-rated motors) minimize failures. The maintenance-friendly structural design reduces upkeep needs, extends service life, and significantly lowers long-term operational costs.
