Shaxian screw jack

Shaxian Screw Jack Screw jack, also known as mechanical jack, is driven by manpower through a screw pair, and the screw or nut sleeve is used as the lifting component. Ordinary screw jacks rely on the self-locking effect of threads to support heavy objects. They have a simple structure, but have low transmission efficiency and slow return. The thread of the self-lowering screw jack has no self-locking function and is equipped with a brake. By relaxing the brake, the weight can quickly descend on its own, shortening the return time. However, this kind of jack has a complicated structure. Screw jacks can support heavy objects for a long time, with a maximum lifting capacity of up to tons, and are widely used. After the horizontal screw is installed on the lower part, the heavy object can also be moved laterally in a small distance.
1. Scope of application
This product belongs to the category of lifting tools and is a multi-purpose product. It is suitable for rail vehicle construction, construction engineering support and general lifting and lowering of heavy objects. Due to its compact and lightweight structure, this product is easy to carry and maintain, so it is widely used in mobile lifting operations. In addition to the above functions, it can also disassemble bearings, gears, pulleys and other workpieces in a variety of mechanical equipment. It is currently used in machinery and automobiles. An indispensable lifting tool in the maintenance industry. Its spiral is not limited by direction and is currently a more advanced disassembly tool than the hydraulic series.

3. Structural performance
This product mainly consists of a main frame, a base, a pair of large and small bevel gears, screws, nuts, lifting sleeves, thrust bearings, ratchet sets, cross arm pull feet, etc.
The screw jack adopts the mechanical principle. After pulling the handle back and forth, pulling out the claw will push the ratchet to rotate in the clearance. The small bevel gear drives the large bevel gear to rotate the lifting screw, so that the lifting sleeve can be lifted or lowered to achieve the desired effect. The purpose of lifting force.
4. How to use
Precautions before use:
Estimate the lifting capacity, choose the appropriate jack model, and avoid overloading.
Check whether the jack is normal.
Determine the center of gravity of the lifting object and select the jack's focus point. At the same time, the softness and hardness of the ground must be taken into consideration, and tough wood should be used to avoid the risk of tilting when lifting.
