QTZ100 Tower Crane

QTZ100(TC6013) QTZ100(TC6013) tower crane instructions (hereinafter referred to as the crane) is jinan construction machinery co., ltd. in accordance with national standards, the development of new construction crane. The machine is a horizontal boom, trolley luffing, upper slewing jack-up multi-purpose crane. Its standard arm length is 50 meters, the extension arm length can reach 55 meters and 60 meters, the maximum lifting weight is 8 tons, and the rated lifting torque is 960 kN. m, with a maximum lifting moment of 1000 kN. Meters. The main features of the machine are as follows:
Climbing frame is mainly composed of sleeve frame, platform, hydraulic jacking device and standard section introduction device. The sleeve frame is set outside the standard section of the tower body, and the upper end is connected with the lower support by bolts.6.93 meters, with a cross section of 2.3 meters × 2.3 meters, is a frame structure welded by steel and steel plates. In order to facilitate the safety needs of the jacking installation, there is a special working platform. Sixteen adjustable rollers are installed on the inner side of the climbing frame along the main chord of the tower body and supported on the outer side of the main chord of the tower body. On the cross beam of the climbing frame, weld two ear plates and the hydraulic system oil cylinder to bear the jacking load of the oil cylinder. The lower part of the climbing frame is equipped with two swinging climbing claws operated by the lever principle, which are used as the weight of the climbing frame to support the upper structure in the process of recovering the piston of the hydraulic cylinder and introducing the standard section.
The upper and lower chords of the jib are square tubes made of two angle steel welding. The whole jib is triangular in section and high1.2 meters, 1.4 meters wide, with a total length of 63.20 meters, is divided into ten sections, and the sections are connected by pins, which is convenient for disassembly and assembly. In order to improve the lifting performance and reduce the weight of the boom, the boom adopts double lifting points and variable cross-section space truss structure. The trolley traction mechanism and hanging blue are placed in the first section of the boom for easy installation and maintenance. The first section of the boom root is connected with the rotating tower body by a pin shaft.
