L68B1 Mast Section How to adjust the height of tower crane rental equipment
During the construction, some high-rise buildings must use tower rental equipment. When in use, some height adjustments are required for tower lifting equipment. However, because in some high-rise buildings, how to control the equipment to prevent accidents is a very important issue.
The lifting weight of the tower varies with the amplitude. The product of the lifting weight and amplitude is called the load torque and is the main technical parameter of the crane.
Through the rotary mechanism and the rotary support, the lifting height of the tower is large, and the inertial quality of the rotary and walking is large. Therefore, it needs to have good speed regulation performance. In particular, the lifting mechanism requires light loading, heavy loading, slow loading, and installation. In place of micro-motion. In addition to the resistance speed regulation, it also uses Eddy current brakes, FM, pole change, controllable Silicon electromechanical joint speed regulation.
In order to ensure safety, tower cranes have good safety devices such as load, amplitude, height, load torque and other restrictions, as well as stroke limit switches, tower top signals, wind detectors, wind clamping rails, climbing ladders, walkways, etc.. Point the arm frame and arm lever and pin shaft. Prepare two support frames or sufficient pillow blocks, assemble the reloader frame in the order specified in the instruction manual, place it on the support frame or pillow, and then assemble the arm frame lever on the reloader frame.
The variable size car equipped with a car repair platform is loaded into the two string rods under the lifting arm. Install the corresponding amplitude indicator every 10 meters, and check that all pins and opening pins of Heqi's heavy arm pull rod are interspersed with firm. Hang up the heavy arm assembly: first in the ground test hanging, grasp the center of gravity, and then formally suspended, with the pin shaft with the root of the rotary support frame side hinged.
