The Growing Crane Industry

With the emergence of new technologies, new processes and new products in the industry, it is also necessary to continuously formulate new standards to apply. The standards in China's mobile crane standard system that are equivalent to and modified to adopt international standards should be revised in time with the changes in international standards. Standards formulated with reference to foreign standards should also be appropriately revised after analysis with changes in foreign standards.

The hydraulic transmission luffing drive device of the crane has the characteristics of compact structure and can withstand two-way force, but its piston, cylinder and push rod have certain precision, so it is necessary to strengthen the maintenance. Use a torque wrench to install the connecting bolts, so that the pre-tightening force is relatively uniform. Since the gantry crane is prone to vibration during operation, it is necessary to regularly check whether the bolts are loose. Hydraulic-driven brakes should always check the amount of hydraulic oil, and add an appropriate amount when it is insufficient.

The mechanism movement limit with accurate positioning of the crane, the torque and lifting capacity limiter with high repeatability; the unique and reliable trolley anti-break shaft device and the trolley anti-rope safety device; the driver's cab is independent and side-mounted, with good vision and large internal space. The linkage console is equipped with a soft chair, which is convenient and comfortable to operate; the overall shape of the whole machine is of the international popular style, which is beautiful and generous;
