8/18/2023 0 Comments Screw base jack![]() How frequently will the jack need to move the load? Remember that heat builds up between the machine screw and nut during normal operation. How fast do you need to move the load? Sometimes double lead machine screw jacks or ball screw jacks are a better choice in a given application.ģ. The speed at which the load will be moved is a limiting factor. Consider the travel speed of the DYNAMIC load. How high do you need to lift the load? Choose a jack whose lifting screw is stout enough to handle the load at full rise.Ģ. When jacks are loaded in compression one must consider the load carrying capacity of the lifting screw ( column load). But the selection of the best jack for the application requires further consideration.ġ. Jacks are rated based on their static thrust capacity from 250-pounds to 250-tons. What You Need To Know To Specify Screw Jacks In Industrial Application We have a hassle-free process for delivering what you need. ![]() Joyce offers premium finishes, outdoor paint process, and custom finishes to meet your specifications. Choose from a variety of boot materials and designs for the jacks you select ( translating, keyed, or KFTN). Nuts Each type of adjusting nut has a light or heavy size.Boots and special finishes are available for Joyce Screw jacks. The configuration of the screw for construction, the production process of the manufacturers in various places are similar, the configuration is different, and the configuration can be distinguished from five aspects:ġ) Chassis: The thickness and size of the chassis are different in different regions and manufacturers.Ģ) Reinforcing ribs: Whether there are reinforcing ribs in the connecting part of the screw rod and the chassis, generally according to the requirements of the project, the longer top supports of the screw are directly equipped with reinforcing ribs, and the shorter bottom supports are rarely equipped.ģ) The length of the screw is generally from 40 to 70, and the thickness of the screw is generally φ28, φ30, φ32, φ34, φ38mm.Ĥ) There are two production processes for adjusting nuts equipped with support: iron castings and stamping forming parts. The hot-rolled screw has a beautiful appearance and slightly higher cost the cold-rolled screw has a less beautiful appearance and has a slightly lower cost. According to the production process of the screw, the solid jack can be divided into hot-rolled screw and cold-rolled screw. The wheeled jacks are generally galvanized and are used in the lower part of the movable scaffold to facilitate the promotion of the construction process ordinary jacks are used in the construction of engineering buildings to support stability.Ĥ. According to whether it has wheels or not, it can be divided into: ordinary top support and leg wheel top support. The lead screw of the hollow jack is made of thick-walled steel pipe, which is lighter the solid jack is made of round steel, which is heavier.ģ. According to the material of the screw, it can be divided into two types: hollow jack and solid jack. ②The bottom support is used at the lower end of the steel pipe in the construction of the construction project, the chassis is at the lower part, and the chassis can not be folded Ģ. ① The upper support is used on the upper end of the steel pipe, the chassis is at the upper end, and the chassis has hemming According to the part used, it can be divided into top support and bottom support With the rapid development of real estate and three-dimensional transportation in recent years, the amount of roof support has also made rapid progress.ġ. It is most used in the construction process of concrete pouring of construction. The application of jack base: It is used with steel pipes and scaffolds in the construction process to adjust the height of scaffolds and pipe structure, balance supporting weights, and load-bearing.
