Embodiment 1
[0016] A cab hydraulic lifting device, such as figure 1 , figure 2 As shown, it includes two electric pumps 1 connected in parallel and manual pump 2 connected in series with electric pump 1, which greatly reduces the hydraulic pulsation of the system, makes the actuator run more smoothly, and has a larger flow rate, thereby greatly shortening the turning time of the cab and saving The time required for cab overturning maintenance improves the work efficiency. The electric pump 1 and the manual pump 2 are connected by the oil pipe 3. The oil pipe 3 is made of stainless steel pipe, which is easy to form, suitable for making pipelines of different shapes, and has strong weather resistance , strong rust resistance, high strength, high fatigue resistance, the electric pump 1 is equipped with a motor 4 connected to the electric pump 1, the motor adopts 24V voltage, permanent magnet DC motor, low noise, waterproof and dustproof, high speed and overheating Protection function, high...
