2. Product Introduction
The LQ Series European Style Single Girder Overhead Crane is a lightweight-to-medium lifting equipment designed per FEM/DIN European standards. Optimized for compact structure, light weight, and low headroom, it maximizes workshop space utilization. Ideal for factories, warehouses, yards, and workshops, it efficiently handles material handling with high stability and reliability.
3. Key Features
• Optimized Lightweight Structure
Box-type girder designed via finite element analysis; lighter than conventional cranes, reducing wheel pressure and workshop load, cutting civil engineering costs.
• High Space Utilization
Low-headroom design minimizes the crane's height, increasing hook lifting height to fully utilize vertical workshop space.
• Smooth & Quiet Operation
Equipped with three-in-one geared motors and precision wheels; smooth travel, low noise, improving working environment.
• Modular & Easy Maintenance
Modular components simplify installation and maintenance; key parts are easily accessible, reducing downtime.
• Advanced Safety Protection
Complete safety devices: lifting height limiter, travel limit switch, overload protection, emergency stop, and buffer for safe operation.
• Flexible Control Modes
Supports pendant control, wireless remote control, and cabin control (open/closed type).
• Energy-Saving & Eco-Friendly
Efficient drive system reduces power consumption; long service life, low maintenance, aligning with green production.
