Lifting machinery is an important tool and equipment for modern industrial enterprises to realize the mechanization and automation of the production process, to reduce the heavy manual labor and improve the labor productivity. Cranes are an important material basis for mechanized operations and are the main fixed assets in some industrial enterprises. For industrial and mining enterprises, port terminals, station depots, construction sites, as well as marine development, space navigation and other departments, the crane has become a major factor in the production, in the production of efficient work, constitute a reasonable organization of mass production and mechanized water operations Based, is one of the important signs of modern production. In one of the key positions to increase one or two lifting equipment, labor productivity will grow exponentially.
In the actual production, we will always encounter some heavy objects such as machine tools, heavy boxes, downhole track and so on in the absence of lifting equipment to move or lift the situation, it is difficult to achieve only by the workers, At this time we need to use the jack. Jacks are closely related to our lives and are widely used in various industries such as construction, railway, vehicle maintenance and so on. Therefore, the development of jack technology will directly or indirectly affect the normal operation and work of these departments. Spiral jack is a jack, spiral jack is by the human through the screw auxiliary drive, its compact structure, low cost, easy to use to carry; to long-term support heavy objects, the maximum weight has reached 100 tons, widely used.
Spiral jack use mechanical transmission, mainly include screw, handle, base, screw sets, rotating rods, parts and other assembly made of. Spiral jack The appearance of the spindle with chromium can increase the service life; its height is low, suitable for general narrow space operation requirements, Yang Cheng short, can be used several times the pad, it is by the man through the screw auxiliary drive, its structure Compact, low cost, easy to use and carry; can support heavy objects for a long time, the maximum weight has reached 100 tons, the use of more extensive.
