2.Boom luffing member

It adopts high-strength pull plate structure with high safety factor; the pull plate transition adopts a balanced beam structure with uniform force; the single pull plate is equipped with a "peach" shaped connecting hole, which is easy to install, labor-saving and efficient.

3.Mast

The mast is composed of a box-shaped double-limb structure with a reinforced crossbeam between the two limbs, which provides good stability. The mast lifting cylinder can rotate around the connection hinge of the turntable to realize the lifting and lowering of the mast.

4.Turntable

The turntable is the key bearing structure for connecting the upper and lower vehicles. It adopts a double-sided "I" beam box frame composite structure welded from high-strength steel plates. The control room, main luffing mechanism, engine system, hydraulic main pump, hydraulic valve, electric control cabinet, mast, main boom bottom section, upper counterweight and other components can be connected to the turntable at different positions.

5.Machine structure

The structure and purpose of this machine are as follows:

The main lifting mechanism and the auxiliary lifting mechanism can realize the joint lifting of the main and auxiliary hooks under shield working conditions.
