Double rod large Excavator hydraulic cylinder is a large cylinder with pistons on both sides of the piston rod, usually a double night pressure drive, which can maintain uniform and repetitive motion.
When the working device is fully recovered, it will move When the working device is not fully retracted, the bucket is easily hit by rocks, and the piston of the hydraulic cylinder will generate a large load, causing internal damage to the cylinder and cracks around the pin shaft.
2. Digging with walking force. When hydraulic oil is mixed with water, it is easy to emulsify and deteriorate, and entering the hydraulic system can cause parts to rust. Rust residue will flow in the hydraulic system for a long time, which will affect the hydraulic system, so the action of the large and small arms and bucket will weaken.
3. The cylinder piston rod extends to the excavation limit. When the large oil cylinder retracts to the end position for operation, the working cylinder and frame will generate a large load, and the impact of the bucket teeth and various shaft pins will cause damage to the cylinder and affect other hydraulic components.
