Product Overview


Slewing bearing

It adopts three-row roller spur gear external meshing slewing bearing or elliptical raceway double-row ball slewing bearing, which has high strength, large bearing moment, high precision, long service life and convenient maintenance.


Cylinder assembly

The connection between the boom and the turntable, the frame and the crawler beam, and the counterweight tray and the turntable are all connected by power pins driven by cylinders; the mast lifting cylinder, outrigger cylinder, and track tensioning cylinder make installation and disassembly more convenient; the control room is equipped with a cylinder to realize the vertical flipping and horizontal rotation of the control room.


Control room

The leopard-head-shaped control room designed according to ergonomic principles has a gorgeous appearance, a wide field of vision, and is comfortable and convenient to operate.


Frame

The frame is a box-type radial structure, welded with high-strength steel plates, with good overall rigidity and high strength.


Crawler traveling device

The crawler travel device is divided into left and right crawler travel devices, which are composed of crawler frame, crawler shoe, supporting roller, driving wheel, guide wheel, sprocket wheel, travel mechanism and tensioning device.

Crawler frame: symmetrical on both sides, 1 piece each. The box-type structure welded with high-strength steel plates, the frame installation and positioning is equipped with parallel pads, which has good guiding and wear-resistant effects.

Driving wheel: connected to the planetary reducer housing with high-strength bolts.

idler wheel: adopts double flange design, built-in floating seal, self-lubricating.

Tensioning wheel: adjust the tension of the crawler through the oil cylinder and adjustment pad.

Sprocket wheel: the sprocket wheel has a built-in floating seal and self-lubricating.

Crawler shoe: installed on the crawler beam.

Travel mechanism: normally closed planetary gear reducer, strong travel power, extremely high flexibility and maneuverability. Multi-plate wet normally closed brake, spring brake, hydraulic release.


Hydraulic system

The load-sensitive LUDV system with hydraulic pilot proportional control is used, which has precise speed, sensitive operation and good micro-movement. The main valve can realize compound operation of multiple actions, with compact structure and convenient maintenance.

Special rotary closed system design, smooth start and stop, good micro-motion, excellent proportional characteristics, strong resistance to load change interference, meet the requirements of fine lifting operations.
