The hydraulic cylinder of the dump truck operates on Pascal's Law as its core principle. As the actuator of the hydraulic system, it converts hydraulic energy into linear reciprocating mechanical energy. During lifting, the power take-off drives the hydraulic pump to output high-pressure oil, which enters the rodless chamber of the cylinder through the reversing valve. Under sealed isolation, a pressure difference is created, pushing the piston and piston rod to extend. Combined with a check valve to maintain pressure, this achieves stable lifting of the truck bed. During descent, the reversing valve opens, allowing the oil to flow back to the tank. The piston rod retracts under its own weight and load. The cylinder body integrates a buffer and venting structure to avoid impact at the end of the stroke and ensure smooth operation, making it suitable for reliable lifting and lowering control under heavy-duty conditions.

Our dump truck hydraulic cylinder adopts heavy-duty telescopic structure, with high-strength cylinder body, reliable sealing and good pressure resistance. It runs smoothly, has strong load capacity and long service life, which can effectively ensure stable lifting and safe operation of tipper trucks under harsh working conditions.

• Please ensure the hydraulic oil is clean and of specified grade to avoid seal damage and system blockage.
• Do not overload the hydraulic cylinder beyond its rated pressure and stroke to prevent deformation or oil leakage.
• Regularly check sealing parts, pipe connections and fastening bolts for any looseness or wear.
• Avoid impact and lateral force during operation to protect the piston rod and cylinder body.
• Do not disassemble the cylinder at will; maintenance should be carried out by professional personnel.
• Keep the piston rod surface clean and scratch-free to ensure good sealing performance.
• Operate the lifting system gently to avoid sudden movement which may cause equipment failure.
