Product Introduction
XG bulldozer which has excellent power, reliability and a long service life. Through the introduction of Japanese D65A-8 bulldozer technology, at the same time absorb the advantages of D60A-8. XG crawler bulldozer has been developed by the domestic design. The TY320 bulldozer adapt Cummins diesel engine which provides an output of 235 kW 320HP with excellent productivity.
Product Advantage
Powerful and efficient power core: The Cummins engine equipped is renowned for its high reliability and excellent fuel economy, ensuring that the bulldozer can continuously and stably output even under heavy load conditions.
• Humanized operating environment: Equipped with an arc-shaped six-sided air-conditioned cab, it offers a wide field of vision and good sealing performance, effectively blocking noise and dust. The ergonomically designed control system and adjustable seats help reduce the labor intensity of the operators.
• Reliable transmission and driving system: Equipped with a power shift gearbox and a wet steering clutch, it ensures smooth gear shifting and high transmission efficiency. The sturdy walking mechanism ensures durability and passability under harsh construction site conditions.
• Safety Assurance: An independent rollover prevention device (ROPS) has been designed, providing additional safety protection for the driver.

Product Uses
•Large-scale mining: This is the core application area of TY320 235. Its powerful engine and solid structure (such as the bulldozer shovel, track plate, etc. made of high alloy materials 5) can efficiently carry out heavy tasks such as ore stripping, pushing and transportation, and waste dump management 28.
• Major infrastructure construction: In the initial stage of large-scale projects such as highways, railways, airports, and ports, TY320 can be used for large-scale land leveling, roadbed filling, and cutting excavation, etc., quickly opening up the working face for subsequent construction.
• Energy and water Conservancy projects: In the construction of water conservancy hubs, reservoir DAMS and other projects, a large amount of earthwork and stonework need to be handled. TY320 is capable of undertaking the tasks of earthwork excavation, transportation and compaction.
• Farmland renovation and large-scale land leveling: It is applicable to basic construction and renovation projects of large-scale farmland, such as reclaiming wasteland, building terraced fields, and conducting large-scale land leveling, effectively enhancing land utilization efficiency.
Product Operate Guide
check before startup
1. Daily inspection: Check whether the oil levels of engine oil, coolant, hydraulic oil, etc. are normal, and inspect whether all components are loose or damaged.
2. Safety Confirmation: Ensure that the gearshift lever is in neutral (N) position, the brake pedal is locked, and the control levers of the scraper and the soil loosener are locked and lowered to the ground.
startup and preheating
1. Start the engine: Turn the key to the "Start" position. Each start should not exceed 10 seconds. If it fails, wait for 2 minutes. After startup, the key automatically returns to the "ON" position.
2. Preheating operation: After starting, let the engine run at low speed without load and check if the oil pressure gauge on the instrument panel indicates within the normal range. 5. After the water temperature gauge indicates the normal range, load operation can be carried out.
It is strictly prohibited to operate at high speed and high load immediately after starting, as this will seriously wear out the engine.
️ basic driving
1. Start: Lift the shovel to 40-50 centimeters above the ground, release the brake lock, select the desired gear, and gently press the deceleration pedal to start smoothly.
2. Steering: Gently pull the steering lever. On flat ground, pull the joystick of the direction you turn to. Special note: When turning on a slope, the operation method may be opposite to that on flat ground. When turning right on a downhill slope, you need to pull the left directional pole.
3. Speed change/Reversing: Speed changes can be made while walking, but deceleration should be carried out before reversing (forward/backward) to reduce impact.
FAQ
A1: This is the first step to ensure safety. Please be sure to check:
• Oil level: Check if the oil levels of engine oil, coolant, fuel, and hydraulic oil are between the upper and lower marks on the dipstick.
• Leakage situation: Check for any traces of oil or water leakage on the ground and under the machine.
• Safety devices: Confirm that the gearshift lever is in "neutral (N)" and all control levers are in the "locked" or "neutral" position
A2: Strict daily maintenance can greatly reduce malfunctions.
• Maintenance per shift (8-10 hours) : Clean the entire machine, check the fasteners, inspect the oil-water separator and drain the water.
• Regular maintenance (refer to the official manual) : Replace the engine oil, oil filter, fuel filter, hydraulic oil filter and air filter strictly in accordance with the cycles specified in the operation manual. This is the key to ensuring the lifespan of the equipment.
A3: This might involve the walking system:
First, check the simple items: whether the transmission oil level is normal and whether the filter is clogged.
• Complex causes: It may involve problems with the transmission itself, the steering clutch or the brake band. Such problems require diagnosis by professional maintenance personnel.
A4: This is usually a problem with the hydraulic system:
First, check: whether the hydraulic oil level is too low, whether the hydraulic oil filter element is clogged, and whether there is any obvious leakage in the hydraulic pipeline.
Further analysis: If the above is normal, possible causes may include a decline in the efficiency of the hydraulic pump, jamming of the control valve core, or internal leakage in the cylinder. Professional testing equipment is needed for pressure testing to determine.
A5: This is usually a sign that there is a problem with the single-sided steering clutch or brake.
• Initial operation: You can try to conduct a left and right steering test on a safe open ground to feel if the pulling forces on both sides are consistent.
Important Notice: Deviation during driving may affect the accuracy and safety of the operation. It is recommended to contact the service personnel as soon as possible for adjustment or maintenance.
