Mast Section,Standard Section,Body of Tower Crane
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

Automatic impeller blasting and spraying assembly line
The company adopts the world first-class automatic spraying
assembly line.
The large structure parts are dealt with impeller blasting before
spraying.
That effectively removes steel surface oxides and welding spatters,
eliminates the internal
stress in welding process, increases the parts'anti-fatigue strength
and steel surface hardness, and increases painting adhesion,
so that it prolongs the service life of the product, maximizes
efficiency, and saves energy.
