230HP mini crawler dozer, SD23 small bulldozer for sale with weichai engine

Product Features
Drive system
The reliable power-shift transmission, the steady hydraulic torque converter and the stage-II spur-tooth final drive could perform the effective power output and produce the high efficiency.
Hydraulic torque converter could protect the drive system against the sudden torque impact and the vibration.
Planetary type transmission with power shift has the forward three gears, reverse three gears, and the clutch with high diameter, high capacity and oil-cooling type, featuring high efficiency.
Chassis system
The final drive is of low drive type, providing the strong driving force and the effective gradeability.
The balance beam is floatingly connected to the trolley through the rubber damper, not only lowering the impact load transferring to the chassis system also raising the swinging angle of left and right trolleys. That profiles the work terrain, furthering the trafficability on the uneven road.
The standard four rollers and one track (sprocket roller, idler roller, track roller, carrier roller and track) come from Shantui. In addition, track type chassis has the high reliability and the load-bearing capacity, suitable for all kinds of complex working conditions and with the processing technologies reaching the advanced world standard.
Cooling system
The independent engine radiator, the chassis oil cooler, the coolant matching with the Chongqing Cummins engine and the air cooler provide the excellent cooling performance and the simple maintenance for this bulldozer, ensuring machine works continuously.
Structure
The main frame of box type adopts the quality material and the strength castings and enjoys the high impact load and torsion, able to work continuously even under the harsh conditions. In addition, the quality welding seam could ensure the main frame works in its life cycle.
Drive environment
The operator will feel more safe and comfortable due to the new hexahedral cab that provides the big room and the expanded outlook and the vibration damper, as well as the electronic monitor mounted according to the user requirements.
According to the man-machine engineering, the driver’s seat and handle could be easily adjusted upward, downward, forward and backward. In addition, the speed control, the steering wheel and the accelerator are on left side and adopt the cable type. The working equipment is on right side and adopts the servo-control system, realizing the flexible process and relieving the fatigue.
Accessories for working parts
The standard straight shovels have the excellent durability due to the high cutting force, high-strength structure and high-performance material and thus are available for all tough environments. Besides, the angle shovels and semi U-shovels are available to users.
Large single-tooth ripper with the adjustable penetration angle is used to loosen the soil layers such as the clay and the frozen soil and to peel off the solid surface such as the gravels and the hardened salt mine. The work efficiency and the super penetration are guaranteed with the strength beam, the frame and the tempered tooth bar and tip.
Besides the standard equipments, the special accessories and equipments such as the comb plough are optional to meet the requirements from different users. In addition, the comb plough is suitable for SD32F logging bulldozer.
Safety
The safe warning lamp, the reversing alarm, the horn, the excellent brake and the distinctive painting could effectively protect the periphery personnel and enhance the safety in all-weather operations. In addition, the seatbelt, the handles and the safe signs give the security protection to the operators.
The side guard could effectively protect the engine and the radiator from being blocked and damaged due to the foreign particles, making the entire machine more beautiful.
The standard antifreeze could raise the boiling point and lower the freezing point, effectively preventing against the scales depositing on the engine and the radiator, beneficial to the engine cooling and the protection.
In addition, the sport bars for litters and others are optional and could protect the operators in emergency.
Maintenance and Service
The eye-catching signs say accurately when to maintain the machine. In addition, this battery is maintenance-free. In addition, the open-type hood could have the inside parts exposed as much as possible, easily realizing the inspection and the maintenance.
This maintenance cost is much lower than others due to the reliability and thus the long Mean Time Between Failures (MTBF).
Shantui perfect service network, as well as timely, thoughtful and warmhearted service, could give your assurance to use this machine, satisfying the expectancy for Shantui products.
