XLC220 Crawler Crane Technical Specifications
Crawler crane models: XLC220
Max rated lifting capacity: 220t
Max lifting moment: 1239t.m
Ⅰ.Product Overview
1.Boom combination
The boom of the XLC220 crawler crane is made of large-section, thick-walled, large-diameter, high-strength seamless steel pipes as chord and belly tubes, supplemented by high-strength steel plates welded in sections to form a four-chord space truss structure with equal cross-section in the middle and variable cross-section at both ends.
The maximum lifting capacity of the heavy-duty main boom is 220t/5m (multiplier 18), and the maximum lifting torque is 177t×7m=1239t.m. The main boom length is 17m~83m, and the boom sections are composed of: bottom section boom 1×6m, transition section boom 1×6m, top section 1×5m, middle section 1×3mA and 1×3mB, middle section 1×6mA and 1×6mB, middle section 2×12mA and 2×12mB. The main boom can be equipped with a single pulley at the arm end.
The maximum lifting capacity of the tower auxiliary boom is 80t/10m (multiplier 6). The tower arm is 18m to 63m long, and the arm sections are composed of: bottom arm 1×1.5m, transition arm 1×4.5m, top arm 1×3m, middle section 1×3mB and 1×3mC, middle section 1×6mB and 1×6mC, middle section 1×12mB and 2×12mC, front bracket 1×5.8m, rear bracket 1×5.5m. The tower arm can be equipped with a single pulley.
The length of the light main boom is 19.5m to 88.5m, and it is composed of the main boom section and the tower boom section.
The maximum lifting capacity of the fixed auxiliary boom is 75t/7m (multiplier 6). The length of the fixed auxiliary boom is 9m to 30m, and the boom section consists of: bottom section boom 1×1.5m, transition section boom 1×4.5m, top section boom 1×3m, middle section 1×3mB and 1×3mC, middle section 1×6mB and 1×6mC, middle section 1×12mB, and bracket 1×5.8m. Among them, the 9m fixed auxiliary boom can also be used in shield working conditions with the heavy main boom 17m and 20m. The maximum lifting weight of the main hook alone is 200t, the maximum lifting weight of the auxiliary hook alone is 67.6t, and the maximum lifting weight of the double hook compound alternating lifting is 113.1t.
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.
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. It can be connected to the lower vehicle through a slewing bearing, with high overall strength and good stability. The control room, main luffing mechanism, engine system, hydraulic pump group, hydraulic valve, electric control cabinet, mast, main boom bottom section, upper vehicle counterweight and its self-disassembling cylinder (optional) can be connected to the turntable at different locations.
