Product Description

Electric single girder gantry crane is a versatile lifting solution widely used in various industrial settings. Single girder gantry crane is a new type of crane equipment developed according to the daily production needs of small and medium-sized enterprises, production workshops to cooperate with machine production, warehouse loading and unloading and material transportation. It is mainly suitable for ports, mold manufacturing, machinery manufacturing, mines, civil construction sites and places where lifting is required. Single girder gantry crane is usually used for material transportation and construction personnel up and down in construction. It is mostly used for loading and unloading or grabbing materials in outdoor open places and indoor objects to realize the automation of object lifting operations. It can greatly reduce manpower, save enterprise production and operation costs, and improve work efficiency.

This type gantry crane is supported by two legs, which can move on wheels or rails, providing stability and allowing for movement across the workspace. This crane is an ideal solution for medium and low-level material handling. Single girder gantry cranes can be designed with low headroom hoists, standard wire rope hoist, direct-connected end beams, open-tooth end beams, etc. to meet different plant and budget requirements.

Characteristics

Main Beam (or Girder): The main horizontal beam that spans across the gantry crane and supports the hoist and trolley. It can be a single or double girder design, depending on the lifting capacity and span requirements.

Legs (Support Columns): Vertical structures that support the bridge beam and transfer the load to the ground or wheels. Legs provide stability to the crane and are typically designed to handle high loads. Gantry cranes may have either fixed or telescoping legs, allowing height adjustments.
End Trucks: Located at the ends of the bridge, end trucks house wheels or rollers that allow the crane to move along the gantry rails. They provide stable, horizontal travel along the length of the

Hoist and Trolley: Hoist raises and lowers the load. Hoists on gantry cranes are often electric wire rope or chain hoists. Trolley moves along the main beam and carries the hoist, providing lateral movement of the load.

Runway Rails or Wheels: For fixed gantry cranes, runway rails are tracks on the ground that guide the crane’s movement along a straight path. For portable gantry cranes, wheels are attached to the legs, allowing free movement on flat surface.

Advantages

1 Cost-Effective: Single girder gantry cranes are generally more affordable than double girder models, making them a cost-effective solution for many applications.
2 Simpler Design: The single girder design simplifies installation and maintenance, reducing overall downtime and costs.
3 Flexibility: The crane can be adapted to various settings and tasks, making it a versatile choice for many industries.
4 Space Efficiency: Single girder cranes can operate in smaller spaces compared to double girder cranes, making them suitable for facilities with limited headroom and floor space.

Application

1 Manufacturing Plants: Used for lifting and moving heavy machinery, components, and materials within the plant.
2 Warehouses: Ideal for loading and unloading goods, as well as organizing and stacking inventory.
3 Construction Sites: Utilized for handling construction materials and equipment, facilitating efficient material transport.
4 Shipyards: Employed for loading and unloading ship components, cargo, and materials.
5 Maintenance Facilities: Used for lifting and positioning heavy parts during repair and maintenance operations.
