XLC260 Crawler Crane Technical Specifications
Crawler crane models: XLC260
Max rated lifting capacity: 260t
Max lifting moment: 1430t.m
Machine structure
The structure and purpose of this machine are as follows:
No. | Mechanism name | Usage | Layout location |
1 |
Main lifting mechanism | It can be used as main hook winch when working with heavy main
boom, heavy main boom with arm end pulley, fixed jib (including
shield), tower jib, tower jib with arm end pulley and light main
boom. | The bottom section of the main boom is close to the root |
2 |
Auxiliary lifting mechanism | [1] When the heavy-duty main boom with arm end pulley and fixed jib
(including shield) is used, it is used as a secondary hook winch [2] When the tower jib (including arm end pulley) is used, it is
used as a tower boom luffing winch |
The bottom section of the main arm is close to the upper part |
3 | Single pulley lifting mechanism [optional] | When the tower arm is working with arm end pulley, it is used as
auxiliary hook winch | Front of turntable |
4 | Luffing mechanism | Main boom luffing | Behind the turntable |
5 | Slewing mechanism | Crane slewing | Front of turntable |
6 | Traveling mechanism | Machine traveling | 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.
6.Lifting mechanism
The lifting mechanism includes the main lifting mechanism, the
auxiliary lifting mechanism and the single pulley lifting mechanism
(optional). The lifting mechanism is driven by a motor with a
planetary gear reducer, and the main hook or auxiliary hook is
lifted and lowered through the drum, guide pulley and lifting
pulley group.
The lifting mechanism has a built-in planetary reducer and adopts a
normally closed brake to realize the "spring brake/hydraulic
release" function, which is safe and reliable. The drum adopts a
double-fold multi-layer winding drum made of ductile iron, which
has good vibration absorption, ensures that the wire rope is wound
in multiple layers without tangling, and effectively extends the
service life of the wire rope.
The lifting mechanism uses an independent steel core, high breaking
tension, high extrusion resistance and anti-rotation special steel
wire rope, with a rated single rope tension of 13.5t, a wire rope
diameter of φ26 mm, and the main, auxiliary and single pulley
lifting rope lengths are 620m, 455m and 250m respectively.
7.Luffing mechanism
The luffing mechanism includes the main luffing mechanism and the
tower arm luffing mechanism. The main luffing mechanism is
independently driven by a double drum and is installed in the
middle of the turntable through a pin shaft.
The main luffing mechanism is driven by a motor to drive the
planetary gear reducer, and the main arm luffing is achieved
through the drum and the luffing pulley set.
The main luffing mechanism has a built-in planetary reducer and
adopts a normally closed brake to achieve the "spring
brake/hydraulic release" function, which is safe and reliable.
The main luffing drum is equipped with a ratchet locking device,
and the ratchet is driven by a hydraulic cylinder to achieve
multiple locking protection.
The main luffing drum is made of ductile iron with double-folded
multi-layer winding double drum, which has good vibration
absorption, ensures that the wire rope is wound in multiple layers
without tangling, and effectively extends the service life of the
wire rope.
The main luffing mechanism uses a high breaking force wire rope,
with a rated single rope tension of 10.8t, a wire rope diameter of
φ26mm, and a length of 275m.
The tower arm luffing mechanism and the auxiliary lifting mechanism
are the same device, which is installed at the bottom section of
the main arm. The tower arm luffing is achieved through function
switching.
