Description
U Type Subway Turn Slag Hook Gantry Crane also known as subway slag flipping machine, slag flipping gantry crane, slag flipping gantry crane, etc., is a specialized gantry crane used for excavation in subway and tunnel construction projects. The U-shaped subway slag flipping hook gantry crane consists of a bridge, a large vehicle, a small car, a lifting mechanism, a hopper tipping device, an electrical control system, and other parts. Its workflow is as follows: after the slag is loaded into the hopper, it is lifted to the designated height by the lifting mechanism above the trolley, then loaded into a large cart on the ground and directly transported to the designated position. Finally, the hopper is overturned by the tipping device to successfully pour out the slag.

 

 

Working Condition
1. Metal structures and mechanical parts should have sufficient strength, stiffness and buckling resistance.
First of all, it is required that parts and metal structures are not damaged after being loaded. For parts such as steel wire ropes with complex stress states, static strength calculations are usually performed with a higher safety factor based on the main load and main deformation form. It must also be required that the deformation of the component under load is within the allowable range, that is, it should have sufficient stiffness.
2. The whole machine must have relatively high anti-overturning stability.
3. The prime mover has the power to meet other requirements, and the braking device should provide the necessary braking torque.

 

Features
1.The long-term accuracy and reliability of the subway slag-discharging gantry crane ensures long-term trouble-free operation.
2.The bridge frame of the subway slag-discharging gantry crane adopts box-type main beam and automatic submerged arc welding.
3.The control room of the subway slag-discharging gantry crane has a wide view, and all mechanisms are operated in the control room, making the work more comfortable.
4.All components of the subway slag-discharging gantry crane are standardized, serialized and universal.

Spare Parts

Main beam

The main beam is a box beam or H-beam structure, welded and formed from steel plates. The steel plate material is domestic steel (Q235B). The vertical winding is in accordance with Chinese national standards. All steel plates are subjected to shot blasting pre-treatment to achieve Sa2.5 level standardization. Before welding, the steel plates are carefully inspected and cleaned, usually by automatic welding machines (MIG or semi-automatic welding).

Ground beam

The lower beam is also a box-shaped structure, mainly composed of cover plates, webs, ribs, flange supports and other parts. The production process is similar to that of the main beam and other box beams. After the lower beam structure is completed, the bent plates are assembled according to the drawing. The flange support is welded to the lower beam after the lower beam is made to ensure the level of the flange surface. When the lower beam and the leg are assembled, the flange on the flange made on the leg is welded to the leg. The appearance quality and geometric dimensions of the lower crossbeam after production meet the requirements of the standard GB14406-93.

Trolley

Crane trolley is a load-bearing equipment that can travel along the running track, transport goods, and lift operations. It is usually used as a supporting component for large lifting equipment such as bridge cranes, gantry cranes, gantry cranes, and cantilever cranes. It is mainly used for logistics handling and heavy lifting operations in factories, docks, shipyards, and other places.

Crane remote control

Industrial wireless remote control is a remote wireless remote control device specifically used to control construction machinery or industrial equipment.
