The L-shaped single-girder gantry crane is an effective and flexible lifting device, suitable for medium and small material handling. This gantry crane features a compact structure and simple operation. The main girder adopts an L-shaped cross-section, offering high strength and stiffness, enabling it to bear heavy loads. The L-shaped design reduces the weight of the main girder while ensuring strength, improving overall performance. Its lifting mechanism typically uses CD/MD electric hoists for lifting and moving goods. In addition to the wire rope hoist, users can also choose electric trolleys as the lifting mechanism to achieve greater load capacity. The electric hoist can move laterally along the main girder, enabling precise positioning of goods. One side of the leg is a rigid leg, rigidly connected to the main girder, providing stable support; the other side is a flexible leg that can be adjusted to accommodate track deviations and uneven ground.
It can meet various lifting height and span requirements. The L-shaped single-girder gantry crane is an ideal choice for factories, warehouses, workshops, and other locations.
The L-shaped structure saves space, especially suitable for environments with limited height and area.
Span, height, and lifting capacity can be customized as needed to adapt to various working conditions.
Made of high-quality steel and advanced welding technology, ensuring the equipment is sturdy and durable.
