Description

Technical Field

[0001] This utility model relates to the field of crane technology, specifically to a gantry crane with a pergola-type electric hoist. Background Technology

[0002] The truss-type electric hoist gantry crane is a lightweight gantry crane with a truss structure (truss beam). It features light weight, strong wind resistance, and a large span, making it suitable for material handling operations in open-air yards, construction sites, and precast component factories. In open-air yards, it can be used for stacking and unloading materials such as steel, timber, and stone. In bridge construction, it can assist in the hoisting of precast beams and pier construction. In wind power equipment, it can be used for the temporary lifting of large components such as blades and towers. In warehousing and logistics, it can be used in conjunction with electric hoists to achieve efficient cargo turnover.

[0003] Existing gantry cranes with electric hoists cannot adjust the height of their outriggers, which may cause safety hazards and operational obstacles. When operating on uneven ground, if the ground is tilted or there is local settlement, the outriggers cannot be adjusted to compensate, which will cause the entire crane to tilt. This can lead to problems such as the main beam being out of level, the electric hoist getting stuck or derailing, uneven stress on the outriggers, local overload of the structure, weld cracking, or outrigger deformation.
