CABIN TITL SYSTEM
The hydraulic pump is connected to the lifting cylinder with a hose, and the rocker action of the hydraulic pump provides pressure to the lifting cylinder. The direction of the oil circuit is changed through the reversing valve, and the hydraulic pump makes the lifting cylinder complete the turning and homing action of the car cab, so as to facilitate the maintenance and maintenance of the car engine. The hydraulic lock is in the hydraulic system. When the oil pump stops supplying oil, or when the reversing valve is in the neutral position, the load-bearing cylinder bears unfixed forces in two directions, and the pressure oil in the cylinder is easy to leak from the gap of the reversing valve. Therefore, Installing a hydraulic lock between the reversing valve and the oil cylinder can maintain pressure, prevent leakage, ensure the stability of the load-bearing cylinder piston, and ensure the normal operation of the machine.
