Product Overview
1.Boom combination
The main boom length is 19m~94m (standard 64m), and the boom
sections are composed of: bottom boom 1×10.5m, transition boom
1×7m, connecting section 1×1.5m, intermediate section 3×3m
(standard 1 piece), intermediate section 1×6m, intermediate section
3×12mA, intermediate section 2×12mB (optional), and arm head pulley
set 1 piece. The main boom can be equipped with a single pulley at
the arm end.
The tower boom length is 24m~66m (standard 42m), and the boom
sections are composed of: bottom boom 1×9m, intermediate section
1×6mA, top boom 1×9m, intermediate section 1×6mB, intermediate
section 3×12m (standard 1 piece), front bracket 1×9m, and rear
bracket 1×9m. The tower boom can be equipped with a single pulley
at the tower boom.
The length of the light main boom is 65.5m to 104.5m (optional
standard 95.5m), which is composed of the main boom section and the
tower boom section. The light main boom can be equipped with a
tower boom single pulley.
The length of the fixed jib is 7m to 16m (optional standard 7m),
and the boom section consists of: bottom section boom 1×4.5m, top
section boom 1×2.5m, middle section 1×3m (optional), middle section
1×6m (optional), fixed jib bracket 1×7m. The fixed jib can be
equipped with a fixed jib single pulley.
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:
No. | Mechanism name | Usage | Layout location |
1 | Main lifting mechanism I | HB/1,HBS/1,LB/1,LBS/1,HW/1,HWS/1,
HBW/1,HF/1,HFS/1,HBF/1,HBFS/1,TBF/1, TBFS/1 as main hook winch | The lower part of the main boom is close to the middle |
2 | Main lifting mechanism II |
HWS/3, HBW/3, HBFS/3, TBFS/3 as third hook winch | The lower part of the main boom is close to the root [optional] |
3 | Auxiliary lifting mechanism | 【1】HBS/2, LBS/2, HFS/2, HBF/2, HBFS/2, TBF/2, TBFS/2 as auxiliary hook winches 【2】Tower boom luffing winch for tower working conditions | The lower part of the main boom bottom section is close to the
front |
4 | Luffing mechanism | Main boom luffing winch | Center and rear of the turntable |
5 | Slewing mechanism | Luffing mechanism | Front of turntable |
6 | Traveling mechanism | Slewing mechanism | Crawler drive wheel |
The main lifting mechanism and the auxiliary lifting mechanism can
realize the joint lifting of the main and auxiliary hooks under
shield working conditions.
