Track Type Dozer with Ripper , Elevated Sprocket Heavy Equipment Bulldozer

335HP Power Big Crawler Bulldozer SD8B for Engineering Construction and Mining with CAT technology

SD8B is elevated sprocket, track-type bulldozer. Its undercarriage system is elastic suspended, elevated sprocket, hydraulic direct drive, and hydraulic controls. SD8 dozer can be equipped with S-blade, single shank ripper. Main structure uses high strength plate and is suitable for working in stony, worse earth condition. The cab is installed ROPS device and comfortable seat.

Main specifications

Steering and braking clutch

Steering and braking clutch are adjustment-free, oil-type, multi-disc clutch. The braking clutch is pressed by spring, separated hydraulic, constant meshed type. Steering clutch is hydraulic pressed, non-constant engaged clutch. Steering and braking acts simultaneously, operated manually to realize steering slowly, sharply and braking. The braking of entire machine can be realized through the pedal. Braking rod is designed to keep the undercarriage system in braking condition and guarantee the machine not to slip on slope when starting the engine.

Torque converter

Power separating, hydraulic-mechanic drive, single stage torque converter is used in SD8 elevale sprocket bulldozer.

Transmission assembly

It integrates center drive, transmission and speed changing control valve into one component. It can be assembled or disassembled as assembly or as a part. It is very convenient to service. Transmission is multi-stage planetary drive to realize modular assembling and disassembling. Gear the shift can be changed among 1st gear, 2nd gear, 3rd gear forward or reverse rapidly, through multi-functional control valve.

Final drive

Final drive is two-stage planetary reduction gear mechanism. It is mounted at outside of steering and braking clutch. Combined sprocket segment is very convenient for assembling, disassembling and service.

Undercarriage system

SD8 dozer utilizes elastic-mounted undercarriage. The track is triangle shape. The sprocket is elevated. Through floating function of continuous auxiliary suspension device, the machine can travel near obstacle on the ground to improve travelling stability and comfortable of the driver. Ground contact area is increased. Performance of travelling and traction is raised.

ROPS cab

The cab is hexagonal thin wall box-type structure. Glass is mounted at six sides with wide viewing range. Pulling and pushing glass is mounted at back side. Air conditioner can be installed according to the requirement of customer. The structure of Rops is rigid. It can protect the driver efficiently when the bulldozer is in special condition. Adjustable operator ' s seat bias to right 15 ° and fuel tank, engine hood, track are tilting, the driver can has a good front and rear sighting range.

Implement hydraulic system

Implement hydraulic system can control lifting, lowering and tilting of the blade. It also can control the moving of ripper. It mainly consists of oil pump, cylinder, valve group, oil tank line and controlling parts. Implement pump is two group vane type pump. The main specification is as following:

Hydraulic system of tractor

It is composed of oil pump, transmission control valve, steering and braking control valve, sequence valve, torque converter outlet relief valve, filler and oil line, etc. Main pump is three group gear pump. The main performance is as following:
