IV. Main Metal Parts List
 1.Mast Section：

External Dimensions
1645×1645MM   

Overall Height:2800MM

The mast composition consists of a quantity of standard sections.The number of standard sections is determined by the height of the crane. Standard section consists of main chord, horizontal brace and tilting brace, which are welded to a spatial trussing.

2. Jib
 

The hoisting jib is non-uniform section and isosceles triangle type, the upper and lower chord is a square tube welded by two angle bars, the tilted brace  and horizontal brace are made of seamless tube. Both the upper and the outside surface of the lower chord are kept horizontal and vertical, thus,the lower chord can also be used as a rail for jib trolley.

3.Tower Cap

The cat head is a triangular spatial trussing.
The front and rear chord is welded as a
square tube by two angle bars, the brace
of which is made of the seamless tube.

Its bottom is connected with the slewing
tower by pin roll. The front and rear side
of which are installed with pulling plates
that hinged to tie bar of the hoisting jib
and the counter jib respectively. The upper
part of the cat head has a platform, the
installation person can stand on it to
disassemble the crane and thread the hoisting wire rope.

4.Upper and lower pedestal are case structure welded by plate.

5.Counter Jib

The counter jib is a spatial trussing composed of four angle bars. The hoisting mechanism locates at the rear of the counter jib and the counter blocks are located at the tail.

6.Frame
 

Space frame structure welded
by channel steel, angle steel
and steel board

7. Jib Tie Bar

Tie bar of the jib is welded by the solid round steel.
