Cric à vis de haute qualité Factory Pricelist
Screw jacks can be used to lift heavy objects, such as cars, machinery and equipment. Its advantage is that lifting operations can be completed in a small space, and it is suitable for confined or limited Spaces.
Description du produit :
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 top lift. Ordinary screw jacks rely on thread self-locking to support heavy objects, simple structure, but low transmission efficiency, slow return. The screw thread of the self-dropping screw jack has no self-locking effect and is equipped with a brake. Relax the brake, the weight can quickly fall by itself, shorten the return time, but this jack structure is more complex. Screw jacks can support heavy objects for a long time, and the maximum lifting weight has reached 100 tons, which is widely used. After the horizontal screw is installed in the lower part, the heavy object can be moved horizontally for a small distance.

Introduction du produit :
Screw jacks can be used to lift heavy objects, such as cars, machinery and equipment. Its advantage is that lifting operations can be completed in a small space, and it is suitable for confined or limited Spaces. At the same time, the screw jack can realize the continuous rise of the top rod by constantly rotating the screw rod, which has high efficiency and is not easy to be affected by the external environment.
Caractéristiques :
The screw jacks are mechanically operated, tightly meshed and interlocked. Manual rotation, one side of the gear drives the three-ring gear operation at the same time, but also consider the rise and fall of the threaded spindle
1. Light weight, easy to carry.
2. Capacity increased from 3.2 tons to 100 tons.
3. High quality, the most competitive price.
4. Large lifting weight, is the ideal large tonnage mechanical jack
5. Used in automotive, industrial, agricultural, Marine recreation and construction applications where lifting, pushing, spreading, bending, pressing or straightening is required.
