Product Advantages
- Proven and reliable traditional crane design
- Light crane deadweight and compact structure
- Lower initial investment and operating costs
- Simple operation and convenient maintenance
- Flexible hoist and control configurations
- Suitable for general industrial lifting operations
Box Girder
The main girder is fabricated from quality steel plates, typically using 8 mm and 10 mm steel plates according to the crane design and load requirements. The box-girder construction provides dependable structural strength while maintaining a relatively low crane deadweight.
The steel structure is treated to Sa 2.5 before painting. Industrial yellow, orange, and customized colors are available. The standard coating system has a total thickness of approximately 80 μm.
Electrical Hoist
Electric Wire Rope Hoist
Electric Chain Hoist
According to the required capacity and operating conditions, the overhead crane can be equipped with an electric wire rope hoist or an electric chain hoist. The hoist travels along the lower flange of the main girder to provide lifting and cross-travel movement.
End Carriage
The end carriages support the main girder and allow the complete crane to travel along the runway rails. The motor, gearbox, wheels, and travel speed can be configured according to the crane capacity and operating requirements.
Safety Protection
Overload Protection
Travel Limit Switch
End Buffer
Electrical Protection
The standard crane safety system can include overload protection, hook limit protection, overvoltage protection, cross-travel and long-travel limit switches, end buffers, and emergency stop protection.
Typical Applications
- Manufacturing workshops
- Warehouses and logistics facilities
- Machinery assembly and maintenance
- Equipment installation and repair
- Material storage and transfer
- General light and medium-duty lifting
Optional Rail and Power Supply Systems
Crane Rails
Available rail models include 24 kg/m, 38 kg/m, 43 kg/m, QU70, and QU80. The appropriate rail will be selected according to the crane capacity and wheel load.
Conductor Busbar
Different conductor rail and busbar systems are available. We will recommend a suitable power supply system based on the crane configuration, runway length, and local electrical requirements.
Information Required for a Quotation
Please provide the following information so that we can prepare a suitable crane solution:
