Partial lifting operation with the boom, lifting mechanism, luffing mechanism, balance weight and turntable, etc.; alight and walk part of the support. Alighting connection between the use slewing. Crane is generally required down legs, increasing the bearing surface, and the body leveling, to ensure the stability of the crane. Boom structure in the form lattice boom and telescopic arm two kinds. CD1, MD1 series electric wire rope hoist system in the original CD, MD based on the type of improved products. It has a compact, lightweight, safe and reliable, a large degree of component commonality, interchangeability, high lifting capacity, easy maintenance, etc., are widely used, popular lightweight lifting equipment. The hoist and trolley-style fixed categories. Fixed on a fixed foot, down, left, right, divided into different positions A1, A2, A3, A4 four types can be directly mounted on the housing use, Trolley has run function, can be installed on the track used. CD1 type is single speed hoist, MD1 two tranches for the normal speed and slow lifting. The former wire rope pulley luffing, or take a long folding arm length, the length of the larger; latter multi-section telescopic boom box-shaped cross-section, and a luffing telescopic hydraulic cylinders. Driving conditions due to small size, the need to adapt to rapid transfer of the site. Working body can be mechanical, hydraulic and electric. Hydraulic has a compact structure, convenient operation, easy electric single girder crane overload protection and speed advantages. Tire cranes for loading and unloading heavy and often installation, lifting weight is small, do not hit the leg work, and even travel with load. Has good mobility, transfers and convenient features for mobile operations, widely used. The basic technical parameters: Starting weight, lifting height, amplitude, load torque and machine weight. Tire crane boom rated lifting weight by limiting the strength and stability of the machine, with the magnitude of change, in order to prevent overloading must be equipped with torque limiter. Since traveling faster truck cranes, transfer and flexible, chassis and parts supply more convenient, etc., particularly telescopic boom truck cranes, has developed rapidly. Tire Crane is improve mobility and cross-country towards further development directions. Multilateral shaped cross-section telescopic boom, box-shaped radiant chassis, movable counterweight and other new tire cranes continue to emerge. Zhenyu Shandong Heavy Industry Machinery Co., Ltd.
