Recently, with the good market reputation of the Group's road wreckers , and high cost-effective and high-quality services, it has again won the bid for the high-speed system in Heilongjiang Province. It is reported that many of the successful bidders for the KFM5444TQZ are heavy-duty wreckers in the north of the traffic suspension platform. The swing- type structure of the suspended platform is the first in China for the transportation in the north , and after more than ten years of market verification, continuous improvement has been made. The product technology is now very mature. . The advanced slewing bearing mechanism enhances the smoothness of the turntable, improves the operational safety factor, and prolongs the service life of the equipment. At the same time, the technology adopted by the crane is based on the structural form of the truck crane produced by our company. It consists of three arms. The cross section of the outer arm is a hexahedron strip box structure. The cross section of the boom is large, and the weight of the boom is increased to 40 tons. It greatly enhances the use of booms; the inner arm and inner arm are installed, and the telescopic cylinder and pulley block control the expansion and contraction; the hydraulic control rotary drive is used as rotary power to drive the main arm to rotate ± 360° through the turntable, and the main arm elevation angle ranges from 0 to 65. °, the tilt angle is controlled by two amplitude cylinders. The boom support cylinder adopts the design structure of American CENTRUY, and the effective amplitude angle is greater than other domestic similar products. Especially when working sideways, the work efficiency is significantly increased by 20%. The product's rotating boom system also serves as a counterweight.
