Main technical parameters of tower crane

1. Tower crane structure

2. Tower crane foundation

(1) Cast-in-place concrete foundation:

(2) Assembled concrete foundation:

The assembled foundation is composed of several prefabricated concrete components and can be reused many times. Before the tower crane is installed, after each component of the assembled foundation is hoisted into place, the components are connected into a whole by tensioning with steel ropes.

(3) Special basis:

3. Steel structural parts

4. Mechanism of tower crane

(1) Lifting mechanism:

(2) Rotary mechanism:

IACM, three-dimensional modeling drawing of slewing bearing

The slewing mechanism is a working device that realizes the rotation of the boom around the center line of the tower crane, so that the hoisted object can move in a horizontal circle around the center line of the tower crane, thereby expanding the operating range of the tower crane into a space.

(3) Amplitude mechanism:

The luffing mechanism includes a trolley-type luffing mechanism and a boom-type luffing mechanism.
