Product Description
Tower crane Mast Section 

Mast section is composed of standard joints which are formed by group welded of angle steels with the structure of long square space trusses.

Every two standard joints of tower body are connected firmly by Level 10.9 M27 high-strength bolts and screws. Inside each standard joint there is a ladder with the same length so as to facilitate manipulation and maintenance personnel getting on and off tower crane.

There is one rest platform every three joints. All standard joints have interchangeability. By changing the number of tower body standard joints installed, the crane will reach different lifting heights.

Two groovy footsteps are welded respectively on two main chords on the same side of standard joints. This position of main chords has been strengthened. 
While doing jack-up work, with the expansion of jack-up cylinder, shaft heads at two ends of jack-up beams and climbing claws of jack-up set frame fall into the footstep groove successively according to the procedure, so as to make jack-up set frame elevate vertically along with tower body.

When two cycles of motion are completed, the jack-up set frame will elevate one standard joint height. Accordingly, at this time, one standard joint could be added.

Repeat motion like this to make tower body achieve required height. When disassembling the tower crane, the reversed procedure is adopted to lower the height of tower body step by step
