Specification

Advantage
Automatic impeller blasting and spraying assembly line
Adopt the world first-class automatic spraying assembly line. The large structure parts are dealt with impeller blasting before spraying. That remove steel surface oxides and welding spatters effectively, eliminates the internal stress producing in welding process, increases the parts’ anti-figure strength and steel surface hardness, increases painting adhesion and prolong the service life of the product maximizes efficiency and saves energy.

Strict quality examination
The strict quality test, raw material test, test of welding, checking welding quality of appearance, assembly and adjustment of jib, tower head and pivot in factory.

We have professional packing person to pack and put the tower crane in the container or on to the truck.


Components
Mast: the main supporting tower of the crane. It is made of steel trussed sections that are connected together during installation.

Slewing unit: the slewing unit sits at the top of the mast. This is the engine that enables the crane to rotate.

Operating cabin: the operating cabin sits just above the slewing unit. It contains the operating controls.

Jib: the jib, or operating arm, extends horizontally from the crane. A "luffing" jib is able to move up and down; a fixed jib has a rolling trolley that runs along the underside to move goods horizontally.
