Motorized Gantry Crane

Electric chain hoist cranes are compact, lightweight, and reliable lifting devices commonly used for light to medium-duty lifting tasks. They utilize a high-strength chain as the lifting medium and are ideal for precise positioning of loads in workshops, warehouses, and small industrial applications. These cranes are typically mounted on monorails, jib cranes, or workstation cranes, offering flexibility and ease of use in confined or limited spaces.

Compared to wire rope hoist cranes, electric chain hoist cranes are more suitable for lighter loads, cost-sensitive projects, and applications where space-saving, low maintenance, and portability are key priorities. With options for pendant or remote control, they support smooth and safe lifting with simple operation and easy installation.

Main Components

  • Electric Chain Hoist: The primary lifting component, featuring an electric motor to operate the lifting chain and ensure efficient load movement.

  • Load Chain: Constructed from high-strength alloy materials, this chain facilitates controlled, smooth vertical lifting and lowering operations.

  • Trolley: The trolley holds the hoist and moves horizontally across the crane girder, available in both single girder and double girder configurations.

  • Girder: The main structural support beam, which can be designed as a profile girder or box girder, supporting both the hoist and trolley.

  • Hooks: Robust forged steel hooks built to meet industrial safety standards for secure lifting and lowering operations.

  • Control System: Includes a pendant control with a festoon system for wired control, with the option for wireless remote control for greater operator flexibility.

  • Travel Motor & Drive: The crane’s travel motor provides smooth, precise horizontal movement with stepless speed control.

  • Power Supply System: The system uses either a drag chain or cable system to deliver a steady and reliable power supply to the hoist.
