The Spiral Jack consists of a metal connected into a diamond-shaped hinge and a diamond that connects the diamond's opposite face. By using the wrench to turn the screw, you can achieve the effect of raising or lowering. Scissors jacks as standard equipment for most vehicles when you need to replace tires. However, it is worth noting that trucks and high-clean vehicles are equipped with different types of jacks due to their chassis weight and height and both. This particular type of jack is operated by converting the rotary motion into a linear shape because when the jack is placed between the solid ground and the vehicle chassis, the rotation of the screw causes the expansion or contraction of the diamond shape and then converts it into an upward Force or downward force.
Compared with the hydraulic jack, scissor jack than hanging capacity and building type has obvious advantages. So if money is a problem, you can consider using scissors jacks. Scissors jacks also require minimal maintenance, which requires simple lubrication of the screws. Due to the presence of hydraulic systems, ground jacks may require more maintenance, and these hydraulic devices must check for leaks, so maintenance costs may be higher.
On the other hand, the weight of the scissor jack is lighter and the jack may wear more quickly over time. If you like to do automatic maintenance and repair at home, this may be a major drawback. In addition, the scissors jack although the shape is very strong, but under extreme loads may be more prone to failure. So you may have to consider what you want to lift to avoid the disaster. It is difficult to use a jack frame with a scissors jack because the maximum lift height of the jack is usually insufficient to allow sufficient clearance of the jack frame to slide under the vehicle. Therefore, we do not recommend the use of scissors jacks for any type of general maintenance work.
If you feel that only need to carry out simple repairs, you need to lift your car, replace a new tires, scissor jacks may be what you need. For other large operations, small investment in hydraulic flooring jacks is absolutely worthwhile.
