Semi gantry crane is actually a special bridge crane. Users can choose double girder type or single girder type according to the lifting capacity. Under normal circumstances, a single girder semi gantry crane can be employed to handle stuff with lifting weight less than 50t and span less 35m. If it needs wide gantry leg, high speed operation, to lift heavy pieces and long pieces, use should choose double beam gantry crane.
Features:
1. All steel plates are processed by pretreatment production line: Shot blasting – Painting – Paint Drying, Eliminate stress in steel plate, and increase Adhesion between paint and steel plate and anti-corrosion.
2. Adopt Germany Messer plasma CNC cutting machine to cut steel plate with high efficiency and accuracy (±1mm).
3. Rolling drum with seamless steel with pressure 1250t. Auto welding and heavy duty CNC lathe for processing.
4. Double gun gantry submerged arc welding for end beam processing.
5. Welding robot for main beam welding, MAG welding for inside seam welding, Ar+CO2 Mixed protective gas.
6. X-ray flaw detection, Ultrasonic flaw detection for welding seam.
7. High temperature quenching and quenching and tempering treatment for wheels to release internal stress.
8. Annealing furnace (1000mm*4000mm*4000mm) for annealing of trolley, rolling drum, balancing beam, wheel group and spreader.
9. Anti-sway system can be equipped according to customers' requirement.
The semi gantry crane is designed as a highly versatile piece of equipment, well - known for its wide - ranging applications.
1. Structural and Operational Features
Enabling Universal Use
It typically features a single - sided support structure, which gives it a unique combination of stability and flexibility. This design allows it to be easily installed and operated in various settings. Constructed from sturdy materials, it can withstand the rigors of continuous use and heavy - duty loads. The crane is equipped with efficient hoisting mechanisms, ensuring smooth and precise movement of materials.
2. Applications in Open Ground
Outdoor Material Handling
In open ground areas, such as construction sites or large - scale logistics yards, the semi gantry crane proves invaluable. It can quickly load and unload trucks filled with building materials like bricks, sand, or large pre - fabricated components. When used for grabbing materials, its grab attachment can scoop up loose materials like gravel or scrap metal. The crane's ability to move freely across the open ground, covering a significant area, enables efficient handling of large - volume materials, streamlining outdoor construction and logistics operations.
3. Applications in Warehouses
Indoor Material Management
Within warehouses, the semi gantry crane plays a crucial role. It can be used to transport pallets of goods from the receiving area to storage racks. Its single - sided design is especially useful in warehouses where space may be limited on one side. It can precisely position items on high - level storage racks, optimizing the use of vertical space. Whether it's handling small - sized products in a retail warehouse or large machinery parts in an industrial warehouse, the semi gantry crane's versatility allows for seamless inventory management and efficient material movement within the indoor storage environment.
