Analysis of Car Jack Use

Jack can be divided into the rack jack, screw jack (Mechanical) and hydraulic (pressure) Jack and inflatable Jack (pneumatic) four. Use the matters needing attention: The car fully fixed up a car. This is very important, if a car without the vehicle completely fixed, it is possible for vehicle sliding caused by slipping phenomenon in support of. The correct mode of operation is: 1, manual transmission models to pull the handbrake, the gearbox hang into the 1 gear or reverse gear (don't forget to start); 2, automatic transmission models is to pull the handbrake, and transmission up to P block position. 3, the lifting operation of the jack in the car.

Because Jack family cars is often a separate branch of a wheel, so if it is parked on the slope of the ground, change the relative position of Jack rises and body may have a point of view, in the angle of the slope is larger on this point will have a greater change, easy to slip or damage. If the fault happens in the slope, suggest the use of brick or wood tools such as click wheel to prevent them from sliding.

 To tie in with the use of soft road plate. Jack must be used on a hard flat surface, if it is relatively soft ground, such as dirt or sand road, in the use of Jack is recommended before the planks or flagstone mats in the jack under the operation, decrease the pressure, to prevent jack into the loose soft ground.

Must be supported on the chassis of the support point. When using the jack to attention must be supported on the chassis for supporting point, support by family cars often on the inside of the side skirts, two fin like both sides of the chassis, in front of the back 20 cm, 20 cm in front of the rear wheel.

The fins are protruding from the chassis plate, can withstand the pressure of relatively large. If you do not follow the correct mode of operation, the jack on the chassis plate, is likely to cause unnecessary damage to the chassis, and supported on the lower arm suspension is not correct operation, if Jack slipping vehicles fell, chassis and Jack will harm.

Lifting. Many domestic car jack rocker is a split structure, rotating and supporting the wrench and sleeve links, so in the process of lifting jacks, force should be uniform, not too fast or too hard.

 Finally to remind, is the use of such as car jack is only support routine replacement of tires or check suspension, cannot replace the lifting machine is greatly repair work, no body or arm reach under the body, The loss outweighs the gain. danger. Another experience to recommend to you, in the jack lifting, can remove spare wheel or tire into under the body, a temporary insurance, even if Jack problems will not cause a greater loss.
