Product Overview
Slewing mechanism
The slewing mechanism and the slewing bearing are driven by external meshing and arranged in front of the turntable. The motor drives the planetary gear reducer to drive the slewing bearing, which can achieve 360° rotation.
The slewing mechanism has a built-in planetary reducer and a normally closed brake to achieve 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 a free sliding function.
Slewing bearing
It adopts elliptical raceway double-row ball slewing bearing with high strength, large bearing moment, high precision, long life and easy 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 new generation of 1.25m wide extra-large cab has a fully open design, gorgeous appearance, wide field of vision, and comfortable and convenient operation.
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.
Electrical System
The electrical system mainly includes the following parts: engine control, auxiliary equipment, hydraulic system control, torque limitation and safety monitoring, data display, etc.
Composition of electrical system: conventional electrical system and PLC control system.
Conventional electrical systems include power supply, starting control, control room air conditioning, audio, lighting, wipers, etc.
The PLC control system includes the control of main and auxiliary winches, slewing, main boom luffing and other actions, and engine status monitoring. All actions are controlled by PLC logic using CAN-bus technology.
