The floor transmission jack is the simplest equipment with a small lifting height (less than 1m). It uses a steel top lifting device as a working device and lifts the heavy lifting equipment in the stroke through the top bracket or the bottom bracket. Jacks are mainly used in factories, mines, transportation and other departments as vehicle repairs and other lifting, support and other work. Its light, strong, flexible and reliable structure allows one person to carry and operate.
Floor transmission jacks must be used on hard, flat surfaces. If it is relatively soft ground, such as mud roads or sandy roads, it is recommended to use jacks or slabs of wood under jacks before using jacks to reduce pressure to prevent jacks from falling into place. To the soft ground. In sand and even desert road conditions, when using jacks, large areas of wood must be used under the jacks.
When using the floor transmission jack, be sure to support the dedicated support point on the chassis of the vehicle. The support point of the family car is usually on the inside of the side skirt, like the two fins on both sides of the chassis, about 20 centimeters behind the front wheel, and the rear wheel. The front is about 20 cm. This fin is highlighted on the chassis plate and can withstand relatively large pressures. If you do not operate in the correct way, putting the jack on the steel plate of the chassis may cause unnecessary damage to the chassis. In addition, the support on the hanging lower arm is also an incorrect operation. If the jack slips and the vehicle falls, the chassis and Jacks will be damaged.
The general floor transmission jack is only used to support conventional tire replacement or inspection suspension and cannot be used in place of the lift to perform significant maintenance work. It is forbidden to probe the body or arm under the vehicle body to avoid danger. In addition, after the jack is fully lifted, the spare tire or the removed tire can be placed under the vehicle body to make a temporary insurance. Even if the jack has a problem, it will not cause greater losses.
