Is suitable for the maintenance of railway vehicles, mining, construction engineering support, the general lifting and decline. it is easy to carry& maintain, safe and reliable, it is widely applied to the mobility of the lifting operation. Such as replace the bushing for railway vehicles, installation support to steel structure, heavy machinery assembly for hull keel, dismantling round pieces of lifting for automobile. All the above can be solved safely and reliably by the products.. Screw jack, also known as mechanical jack, by the human resources through the screw, screw or nut sleeve as the top lifting parts. Jack screw threads on the self-locking function support weight, simple structure, but the transmission efficiency is low, slow return. auto reducing screw jack has no self locking function, and is provided with a brake. Loosen brake, weight can be decreased rapidly, shorten the return time, but this jack structure is complex. The lower part installed on the horizontal screw, so that the weight can be moved in short distance. Ò»,Product Features: A new series of national stereotypes products. It has a compact structure, small size, light weight, easy to carry, widely used in factories, warehouses, bridges, docks, transportation and construction and other departments of the lifting operation. 1. spiral principle, simple operation, the longest working life 2. light and convenient, durable, easy to use, girls can operate it easily 3. the steel structure, no oil and gas operation, ensure safety first 4. work in any angle, the diagonal, cross or reverse. It¡¯s not compared ¶þ, Mechanical Principle The claw promote Rotary ratchet gap rotation while the handle is pulled, the small bevel gear drives the big bevel gear, that makes the weight lifting screw rotation. And finally, achieve the aim of lifting, dropping or tension. But it is not as simple as hydraulic jack. Èý,Attention 1. Always try to keep the body surface cleaning, regularly
