Car Lift Introduction

Double-column car lifter is a car repair and maintenance units commonly used special lifting equipment, widely used in cars and other small trucks maintenance and repair.

Double column lift is divided into symmetrical and asymmetrical two. The arms of the four arms of the symmetrical lift are approximately equal, so that the center of the car (or the center of mass) is in the middle of the column, and the column of the asymmetric lift is rotated backwards by an angle (about 30 °) The rear arm is slightly shorter. When the car is parked in the proper position of the asymmetric lift, the position of the car is moved backwards, so we can easily move in and out of the door.

Hydraulic double-column lift is currently the most commonly used in the auto repair industry, the most widely used lift, the current market share of about 70-80%. Can be divided into single-cylinder, double-cylinder.

Single cylinder is driven by a hydraulic cylinder, the market is less used.

Double cylinder is driven by two hydraulic cylinders, more commonly used, knights are now produced double column lift are double cylinder type.

From the transmission mechanism to divide the hydraulic lift can be divided into chain drive, direct drive type

Chain drive

The hydraulic cylinders installed in the two pillars on both sides push the chain connecting the column and the lift head so that the slider mounted on the lift head slides along the column to move the lift up and down.

The use of wire rope as a synchronization device to maintain the synchronization of the entire lift. The arm is connected to the lifting head in the column, and when the lifting head moves up and down, it drives the arm to move together.

Direct drive

Lift head directly connected to the cylinder, when the cylinder is working directly to drive the lift head to run. Without any transmission mechanism, simple structure. Greatly reduce the friction and wear and tear, increased safety performance.
