Shantui bulldozer SD42-3 is composed of Shantui absorbing world advanced technology, and successfully used to complete a number of scientific research designing company independent research and development, is the first domestic bulldozer maximum power, the bulldozer assembly independent design of electronically controlled gearbox, roller type K floating installation device, with the international advanced the level of anti roll and anti litter, with damping system of cab, fuel automatic filling system and other advanced equipment, are filled in the domestic blank.
Transmission system:
Drive system for hydraulic mechanical transmission, using self-produced three single-phase Shantui element torque converter, three forward three after the power shift gearbox planetary gear structure; central transmission with a spiral bevel gear, the wet multi disc spring. Hydraulic separation, normally closed type steering clutch friction, floating belt type hydraulic power steering, brakes, steering and braking hydraulic linkage implementation; final drive using a straight gear, a planetary gear reducer two, splash lubrication.
Engine：
Shantui SD42-3 large crawler bulldozer with Cummins KTA19-C525 turbocharged engine, providing higher power and cooling, 310KW rated power and rated speed 2000rpm, strong power, the rigid three point support installation. The inlet temperature is low, to ensure sustainable and efficient operation of engine; cylinder block and cylinder head using the integrated design, Water Leakage, avoid oil leakage phenomenon, a relatively small number of parts, lower failure rate; can adapt to all kinds of difficult and complicated operating environment.
Walking mechanism
The walking mechanism adopts K type elastic suspension connecting trolley, and frame pivot; combined type high strength seal lubricated track, rail backbone section assembly structure; driving wheel, roller, roller guide wheel are made of low alloy steel casting or forging, and the surface heat treatment, including roller, supporting round by the floating seal for permanent lubrication. The track tensioner is a hydraulic cylinder, which can adjust the tightening degree of the track by injecting grease into the oil cylinder.
Bulldozing device and Ripper by hydraulic control. The standard rotary belt tilt cylinder large capacity 16m3 semi U type blade, giant single tooth scarifier adjustable angle. PPC pilot hydraulic system is used.
Single tooth Ripper
The large angle single tooth Ripper with adjustable angle has super penetration; the high strength beam, bracket and heat treated tooth bar and tooth tip provide more durable reliability and service life. It can be used not only for loose clay and hardened frozen soil, but also for stripping operation of hard work such as gravel, hardened salt mine, bedding rock and so on.
Half U shovel
Using the high performance materials of high strength and low alloy welded box type structure, the blade has good cutting force and excellent durability, can adapt to various complicated working environment.
Anti rolling cab
Adopting hexahedral cab, increasing internal space, having wide field of view, damping and sealing technology, can reduce vibration, dustproof and low noise effect; adopt integrally cast instrument panel, adjustable front and rear seats of cab.
In accordance with ergonomics, speed change, steering, throttle control on the left side, the work device is placed on the right side, using PPC pilot control operating system, flexible and flexible operation.
SD42-3 has a new product and new idea, can in the competition to highlight the differences and advantages, accelerate the internationalization process of the market to Shantui bulldozer.
