Mechanical transmission type
Typical power route: engine → clutch → gearbox → drive shaft/chain → drive wheels → tracks.
1. The engine generates power.
2. The clutch controls the engagement and disengagement of power.
3. The gearbox determines the forward, reverse, and speed gears.
4. The driving wheels drive the tracks to achieve complete machine movement.
Features: Relatively simple structure, low cost, easy maintenance, commonly found in entry-level models weighing around 300-500 kg.
Hydraulic/Hydrostatic Drive Type
Typical power route: engine → hydraulic pump → high-pressure hydraulic oil → left/right hydraulic motor → drive wheels → track.
1. The left and right tracks can be controlled separately.
2. Low speed and high torque, suitable for mud, slopes, and complex working conditions.
3. Smooth operation, high-end models can reduce traditional mechanical shifting.
Track steering principle
The tracked Mini Dumper achieves steering by the speed difference between the left and right tracks. When driving straight, the left and right tracks are in the same direction and speed; When turning left, slow down or stop on the left side, and turn right
Continue to drive on the side; Some hydraulic models allow the left and right tracks to rotate in reverse, achieving near stationary rotation.
Principle of hydraulic tipping bucket
The engine drives the hydraulic pump, and the hydraulic oil enters the tipping bucket cylinder through the control valve. When the oil cylinder extends, lift the hopper to complete the pouring process; After the oil cylinder retracts, the hopper resets.
Power route: Engine → Hydraulic Pump → Control Valve → Hydraulic Cylinder → Hopper Tipping.
