What classification of tower cranes

1, according to the structure type:
1) Fixed Crane Tower: The tower chassis by connecting member fixed to the foundation or the structure, conduct tower cranelifting operations.
2) Mobile tower crane: a running device, you can walk the tower crane.
3) self-elevating tower crane: through its own specialized equipment, increase, decrease tower section to change the lifting height of the tower crane, such as: attachment style and self overall climb (internal climbing) tower crane
Attached Tower: support means attached to the wall by anchoring the tower to the building of self-raising tower crane.
Inner climbing tower crane: Set inside the building, by supporting the structure of the special unit, the machine can be increased with the height of buildings and an elevated tower crane.
2, according to the rotary type points:
Slewing tower crane slewing ring provided at the upper portion of the tower crane tower) 1.
Slewing tower crane slewing ring set 2) in the bottom of the tower, the tower is rotated relative to the chassis of a tower crane.
3, according to the erection method points:
1) Non-self-erecting tower crane: relying on other lifting equipment for assembly into a machine tower crane erection.
2) self-erecting tower crane: relying on its own power units and agencies to achieve tower crane transport state and the working state of mutual conversion.
4, according to the amplitude points:
1) trolley tower crane: lifting trolley that run along the luffing jib tower cranes.
2) The boom luffing tower crane: luffing jib for the pitching motion of the tower crane.
3) folding jib tower crane: lifting operations as needed, jib tower crane can be bent. It can also have performance luffing boom and the trolley.
