Product introduction
Yishan TY180 crawler bulldozer with hydraulic mechanical transmission is a product produced under a technology and cooperation contract signed with Komatsu, Japan. It is produced in strict accordance with the D65E-8 product drawings, process documents and quality standards provided by Komatsu, and has fully reached the design level of Komatsu.
Its extended platform frame is specially designed to withstand heavy traction work, so that the rear of the locomotive has more track land and more gravity to move forward to balance the rear load, so that the locomotive can obtain an ideal balance when performing logging and traction operations.
The low-center-of-gravity driving design of the travel system, the extra-long track ground length and 7 rollers provide unparalleled climbing ability and outstanding balance and stability, so it is more suitable for continuous bulldozing and finishing slope operations on slopes, and can obtain root height production efficiency and balance.
The Steyr WD615T1-3A diesel engine with fast response performance is combined with a hydraulic torque converter and a power shift gearbox to form a powerful transmission system, which shortens the working cycle and improves work efficiency. The liquid medium transmission can protect the transmission system from damage and prolong the service life under heavy load.
The hydraulic torque converter enables the output torque of the bulldozer to automatically adapt to the change of the load, protects the engine from overload, and does not stop the engine when it is overloaded. The planetary powershift transmission has three forward gears and three reverse gears for quick shifting and steering.

Bulldozer breakdown tips:
1. Unable to start
The bulldozer failed to start during the unsealing of the hangar.
After ruling out no electricity, no oil, loose or blocked fuel tank joints, etc., it is finally suspected that the PT fuel pump is faulty.Check the AFC air fuel control device, open the
After the air pipeline uses an air compressor to supply air to the intake pipeline, the machine can start smoothly, and when the air supply is stopped, the machine will shut down immediately, so it is concluded that the AFC air fuel control device is faulty.
Loosen the fixing nut of the AFC fuel control device, turn the AFC fuel control device clockwise with a hexagonal wrench, and then tighten the fixing nut. When starting the machine again,
It can start normally and the fault disappears.
2. Failure of fuel supply system
The bulldozer needs to be driven out of the hangar during a season-changing maintenance, but it cannot be driven.
Check the fuel tank, the fuel is sufficient; unscrew the switch at the lower part of the fuel tank, and then turn off the engine automatically after 1 minute; connect the fuel tank directly to the fuel pipe of the PT pump with the oil inlet pipe of the filter
Even if the fuel does not pass through the filter, the car still does not start when it is started again; the manual screw of the fuel cut-off solenoid valve is screwed to the open position, but it still cannot be started.
When reinstalling the filter, turn the fuel tank switch for 3 to 5 turns, and find that a small amount of fuel flows out of the oil inlet pipe of the filter, but the fuel will flow out after a while.After careful observation and repeated
After comparing, it was finally found that the fuel tank switch was not turned on. The switch is a spherical structure, the oil circuit is connected when it is rotated 90 , and the oil circuit is cut off when it is rotated 90 further.The ball valve switch does not
There is no limit device, but the square iron head is exposed. The driver mistakenly uses the ball valve switch as a throttle switch. After 3~5 turns, the ball valve returns to the closed position.
place. During the rotation of the ball valve, although a small amount of fuel enters the oil circuit, the car can only be operated for 1 minute. When the fuel in the pipeline is burned out, the machine will turn off..
