The middle rise car lift is a kind of lift that can be widely used in repair shops. It has the characteristics of compact structure, beautiful appearance, and easy operation. It only needs to use this kind of safe and reliable lifting equipment to lift the car to a certain level. The height of the car can be used to maintain and repair the engine, chassis, transmission, etc. of the car. As the number of private cars increases, the demand for scissor car lifts will also increase. The main performance parameters of the scissor car lifts are: the rated lifting load is 4t; in the case of a load of 2t, it takes 60s to lift from the lowest position to the highest position; when the down button is pressed to make the three-position four-way valve right, the vehicle It takes 40s to drop from the highest position to the lowest position; the motor power is 1.5kW; the lifting height of the lift at the lowest position is 150mm, the maximum lifting height is 1300 mm, and the working stroke is 1150 mm.
The transmission system of the small mid rise scissor car lifting mechanism is driven and controlled by the hydraulic system. The hydraulic cylinder installed on the lifting arm realizes the up and down movement, and pushes the shaft connected to the lifting arms on both sides to make the pulley installed at the upper and lower positions roll along the slideway , to realize the up and down movement of the lift. The main parts of the equipment are: control mechanism, transmission mechanism, executive mechanism, balance mechanism and safety lock mechanism.
Analyzing the force of the scissor lift at different lifting heights shows that under a given load, when the lift is lifted to different heights, the thrust of the cylinder required is different, and the force on each lifting arm and shaft is also different.
