LH Electric Hoist Double-Girder Overhead Crane
Product Introduction
The LH Electric Hoist Double-Girder Overhead Crane is an electric overhead crane equipped with an electric hoist for lifting and material handling operations.
The crane features a compact overall structure, low required headroom, relatively low self-weight and low wheel loads. It is designed for material transfer, assembly, maintenance, loading and unloading operations in industrial facilities.
The LH crane is available in multiple lifting capacity configurations to meet different material handling requirements. It can be used in machinery workshops, auxiliary workshops of metallurgical plants, warehouses, stockyards and power plants. It can also be used as an alternative to conventional double-girder overhead cranes in production workshops of light textile and food industries.
The crane is available with ground control or cab control. The operator’s cab can be provided in open or enclosed configurations, with left- or right-side installation options. Different entrance arrangements, including side, end and top entry, are available according to operating requirements.
The LH crane is suitable for light- and intermediate-duty applications and can operate at ambient temperatures from -25°C to +40°C. It is not intended for use in environments containing flammable, explosive or corrosive media.

Note: The technical data above is based on the available source specification. Some motor model and basic-dimension values in the original document are presented in a low-quality scanned format and should be checked against the original technical drawing before publication. The lifting capacity should also be selected according to the specific crane configuration rather than being interpreted as a single capacity for the entire LH series.
Working Principle
The electric hoist performs the lifting and lowering of loads through the main and auxiliary hook systems. The hoist and crab travelling mechanism move the lifting equipment horizontally along the crane girders, while the crane travelling mechanism moves the complete crane along the runway rails.
The LH crane can be operated from the ground or from an operator’s cab. The cab configuration can be selected according to the operating environment and control requirements.
Applications
The LH Electric Hoist Double-Girder Overhead Crane is designed for material handling and lifting operations in various industrial facilities.
Typical applications include:
- Machinery processing workshops
- Auxiliary workshops of metallurgical plants
- Warehouses
- Stockyards
- Power plants
- Light textile production workshops
- Food production workshops
- Industrial facilities requiring material transfer, assembly, maintenance, loading or unloading
The crane can also be used as an alternative to conventional double-girder overhead cranes for suitable light- and intermediate-duty applications.
The crane should not be used in environments containing flammable, explosive or corrosive media.
