Car Scissor Lift Operation And Maintenance

Scissor lift mainly includes the small car scooter, ultra-thin small car lift and large scissors car lift, scissor lift speed is moderate and does not occupy the car pit position, for the Some models are relatively fixed, work intensity (such as in the bus) repair area is undoubtedly the best choice. And because the structure is simple, good synchronization, commonly used as a four-wheel locator platform.

1. Installation requirements

Scissor car lifts the two platforms to install the ground plane to be in the same level, which is due to the size of the scrapped car lift mechanical insurance is connected with the upper and lower cylinder connection, and only then can guarantee that the same benchmark When the insurance is locked, the two lifting platforms are at the same level.

2. Drop operation

Operation down the operation, and some manufacturers have a down delay function, you can directly press the drop button, and some manufacturers of electronic control part of the non-drop delay function, you must first press the up button, until the insurance teeth off the lock position and then press Drop button.

3. Maintenance

Most of the scissors lifter use differential cylinder to ensure that the main \ secondary platform synchronization, it uses the master cylinder cavity and vice tank under the chamber to achieve the same volume, for the manual fill of the scissor lift may be due to manual ball valve Leakage or main / deputy cylinder internal leakage, resulting in the main \ deputy platform is not synchronized, should open the ball valve active charge, if the charge is too frequent (interval less than a month), should check the hydraulic system, replace the cylinder seal or ball valve; For electric charge, should be a priority check two-way solenoid valve spool, and then check the cylinder.

4. security check

Scissor lift bracket connection must be regularly checked, if found loops loose, fasteners loose, must be tightened in time. In the past two years, most manufacturers have adopted self-locking lock nuts, external support to use closed-loop connection, reducing the impact of lateral force on the bracket connector, effectively preventing the loose parts of the bracket.
