800 tons of longmen shears, equipped with two main shear cylinders with an inner diameter of 450, can reach the standard 800 tons of shear pressure, piston rod, piston guide sleeve using medium frequency quenching process, hardness 50-55 degrees, greater to avoid the phenomenon of oil leakage caused by impact damage, piston rod plating side 0.05mm, To ensure that the oil cylinder is more and more smooth and more and more bright, the piston rod head and the tool holder are connected with the ball head, which can adjust the error by itself, and the oil cylinder will not break.

Overall cast steel tool holder, better integrity, more solid, fixed blade nut can be hidden in the interior, will not be caused by the impact of the screw deformation is not easy to disassemble,
The knife edge is 2 meters, the blade is made of Maanshan h13 material, and the h13 material cushion layer added below the blade can effectively protect the main body of the machine, and the knife change is more convenient. The four sides of the blade can cut about 10,000 tons of wool, which is suitable for small and medium-sized materials with a monthly output of about 3,000 tons.

The slide lining plate on both sides of the cutter seat uses high-force brass and adds graphite, with a hardness of 30 degrees, and the guide groove uses 65 manganese plate, with a hardness of 50 degrees, and is equipped with an oil groove, a soft and hard to reduce friction while realizing automatic lubrication, which greatly reduces the problem of slide wear; The slide adjustment function is also designed on both sides of the slide, which can adjust the gap between the upper and lower blades to solve the problem that thin materials are not easy to cut after cutting thick materials for a long time.

800 tons of gantry shear is equipped with 8 meters of material box, the cylinder push one-sided heavier door cover, the material box internal liner using nm500 wear-resistant plate, high wear-resistant strength, long service life, the use of riveting welding process, not easy to open welding drum warping edge, while the three sides of the material box designed four slides, can effectively prevent the problem of pushing head warping head card.

Hydraulic station part is also the core part of the whole machine, the power is equipped with a 92.1kw servo motor, driving a4v280 series a4v280 high-speed oil pump, a 71kw servo motor, driving a4v200 series a4v200 high-speed oil pump, large flow, lower noise, automatic start and stop, energy saving.

The inside of the tank can be sandblasted to remove rust, and 35 barrels of 46 anti-wear hydraulic oil can be filled.

The pipeline is also pickling phosphating treatment to ensure that the equipment is not stuck in the later use of valve blocking valve, plate cooling with large flow centrifugal oil pump, cooling effect is better.

The control part is controlled by plc automatic + remote control, which can be operated by one person and one excavator, saving labor and improving work efficiency.
