Crawler crane models: XGC150-I
Maximum rated lifting capacity:150t
Maximum rated lifting moment:790.8t.m
6.Lifting mechanism
The lifting mechanism is driven by a motor to drive a planetary
gear reducer, and the main hook or auxiliary hook is lifted and
lowered through a drum and pulley set.
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 lifting mechanism uses a high breaking force wire rope with a
wire rope diameter of φ26mm.
7.Luffing mechanism
The luffing mechanism is driven by a motor to drive a planetary
gear reducer, and the luffing of the main arm is achieved through a
drum and a luffing pulley set.
The luffing mechanism has a built-in planetary reducer and a
normally closed brake to achieve the "spring brake/hydraulic
release" function, which is safe and reliable.
The luffing drum is equipped with a ratchet locking device, and the
ratchet is driven by a hydraulic cylinder to achieve multiple
locking protection.
The luffing mechanism uses a high breaking force wire rope with a
wire rope diameter of φ22mm.
8.Slewing mechanism
The slewing mechanism and the slewing bearing are driven by
internal meshing and arranged at the front of the inner side of the
turntable. The motor drives the planetary gear reducer to drive the
slewing bearing to achieve 360°rotation.
The slewing mechanism has a built-in planetary reducer and adopts a
normally closed brake to realize the "spring brake/hydraulic
release" function, ensuring that the slewing has extremely high
braking safety.
The slewing mechanism is also equipped with a mechanical slewing
locking device to achieve locking protection of the slewing
mechanism.
The slewing mechanism has free sliding function.
9.Slewing bearing
The slewing bearing has the characteristics of large load-bearing
capacity, small slewing resistance, wear resistance and long
service life.
10.Cylinder assembly
In order to realize the self-assembly and disassembly function, the
important pins that need to be disassembled, such as the connection
between the boom and the turntable, and the connection pins between
the frame and the crawler beam, are all connected by power pins. It
is also equipped with a mast lifting cylinder, a counterweight
lifting cylinder (optional) for the power of the counterweight
disassembly and assembly, and an outrigger cylinder for the main
engine to disassemble and assemble the crawler frame. The driver's
cab is equipped with a flip cylinder and a rotation cylinder.
11.Control room
The control room adopts bionic design, with wide field of vision
and comfortable and convenient operation.
12.Frame
The frame is a box-type radial structure, welded with high-strength
steel plates, with good overall rigidity and high strength.
