The lifting capacity of the tower crane varies with the amplitude. The product of lifting weight and amplitude is called load moment, which is the main technical parameter of this crane. Through the slewing mechanism and slewing support, the tower crane has a large lifting height and a large inertial mass for slewing and walking, so it needs good speed regulation performance. The special lifting mechanism requires light load and fast speed, heavy load and slow speed. Bit fretting. In addition to resistance speed regulation, eddy current brakes, frequency modulation, pole change, thyristor and electromechanical combination are often used.

Main Specifications

TIPS: Inspection points of tower cranes:

(1) Check the condition of the metal structure, especially the high-strength bolts. Its connecting surfaces should be cleaned of dust, paint, traces and rust, and tightened with torque hands or special wrenches according to the requirements of assembly technology.

(2) Check whether the bearing clearance of each mechanism transmission system, including each working transmission mechanism, is appropriate, whether the gear meshing is good, and whether the brake is sensitive.

(3) Check the abrasion of the wire rope and the pulley, whether the anti-dropout device and the fixing of the rope end are reliable.

(4) Check whether the electrical components are good, the degree of closure of the contact points, and whether the connection is correct and reliable.

(5) Check if the walking wheel is in good contact with the track and whether the rail clamp is reliable. Whether attachment bolts and clamping blocks are firm and reliable when installing attachment devices and internal climbing devices.
