Product Introduction
YJZ series hydraulic straightening machine is mainly used for the straightening and repairing of U-shaped steel, I-beam and column in coal mine. It can also produce U-shaped steel and I-beam arch ballast of various specifications. It adopts hydraulic transmission and has the advantages of explosion-proof, small size, compact structure and movable use. Because the machine is mobile and the electrical part can be flameproof, the machine can be operated directly underground, greatly reducing the capacity and cost of U-shaped steel, I-beam beam, column lifting repair and downhole reuse. And reduce the unsafe factors in the process of transportation. If the coal mine maintenance department is equipped with this product, it can disassemble and repair all kinds of equipment, which greatly improves the efficiency of maintenance operations. In order to improve the stability of the equipment and increase the working space, the straightening machines above 150 tons are now changed to split structure.
