The Weihua L-type single-girder gantry crane is a general-purpose, medium-capacity lifting device. It features a compact structure, provides ample workspace, and is mainly used for loading and unloading operations in open areas and warehouses.
1. The L-type single-girder gantry crane is suitable for general loading/unloading, hoisting, and lifting operations in open-air freight yards and along railway lines. 2. Due to its structural characteristics, the L-type gantry crane reduces the overall height of the machine while maintaining a certain lifting height, saving costs. 3. It features light deadweight, low wheel load, and reliable performance.
Structural & Design Features
Manufacturing Process: The main girder uses CNC cutting for blanking and advanced welding processes such as submerged arc welding.
Core Structure: Features an L-type structural design, where two columns are connected to the rear of two bases with rollers, forming a stable “L” shaped support. The main girder (gantry) is mounted on these two columns, and the bridge mainly adopts a box-type welded structure, providing good strength and rigidity.
Travel Mechanism: The crane travel mechanism typically uses separate drives, meaning the drive wheels under each leg operate independently, offering flexible steering.
Advantages & Features
Stable Structure
The L-type structure is stable, with light deadweight, low wheel load, and reliable performance, contributing to operational safety.
Flexible & Efficient
Multiple control modes (ground, remote control, cabin) adapt to different needs. Combined with flexible drive forms, it effectively enhances loading/unloading efficiency.
Reliable Manufacturing
Weihua products undergo strict quality control and process assurance. We are a leading company in the industry.
High Cost Performance
As a product with a high degree of standardization and generalization, it offers good economy while meeting常规 requirements.
