Scissor Jack 2 Ton, is a jack, because the structure is like a scissors, used to be called scissors jack. Its structure looks like a scissors, used to be called scissors jack. Scissors jack is the major domestic automobile factory car products, the principles are different. From the metal plate made of the upper pole and the lower pole composition. The cross section of the upper strut and the lower bar are rectangular in the cross section of the teeth and the vicinity thereof, and the metal plates on both sides of the opening are bent inwardly. The teeth on the upper and lower struts are made of metal plates bent on both sides of the opening, and the tooth width is greater than the thickness of the metal plate.
The scissors jack is based on the isosceles triangle of the waist and the shortened bottom edge will raise the geometric principle of the high line. It is through the screw and nut to adjust the upper and lower sides of the isosceles triangle to enhance and drop the height of the bottom. Like the ladder of ordinary life, when the ladder of the arms of the angle of the smaller the higher the ladder, the same way the ladder of the arms of the larger angle of the lower ladder.
Scissor jack Uses: Based on the special structure of the shear jack jacking weight will not be too big, are generally about 2T load. So you do not expect it to jack up the truck. As the scissors jack is a mechanical jack, do not be careful of the phenomenon of oil spill, we can also cross to use. It is suitable for mechanical maintenance, especially the use of car repair, stable and reliable, carrying capacity.
All the car mechanics know that the scissors jack is unreliable. All mechanical lifts are likely to fail and they will suddenly become violent at the time of the load. That's why jacks are used for any car that you actually have to crawl. If the "support" column fails for any reason, either because Jack gave the way or was knocked down, or because the ground was given a little bit after the rain, or an animal was brushing on the pillar at the wrong time You have roughly equivalent to a small car to the ground. The more water in the tank, the greater the force involved, the greater the likelihood of failure. Considering that you have a bunch of logs directly on the tank, I am afraid to be safe when receiving their bounties.
