Scaffold screw jacks are adjustable leveling parts of scaffolds. It is fabricated with adjustable screw stems, jack nut handles with inner threads, and screw jack plates. In scaffolding construction, scaffold screw jacks are able to adjust to a required height easily by rotating the jack nuts.
A scaffold screw jack is also called leveling jack, scaffold screw legs, or scaffold feet. There are many types of scaffold screw jacks: jack base, U head jacks, forkhead jacks, J head screw jacks, etc.
Among them, the base jack is one of the most common scaffold screw jacks. It is a type of scaffold screw jack with a base plate. Thus the base jack is also called a threaded base plate, jack base plate, jack base, etc.
An adjustable base jack is used to level the scaffold height under the scaffold verticals or starter(ring lock system).
The base plate sizes of the scaffold screw jack base are customized. While the most used base plate sizes are 150x150mm, 140x140mm, 120x120mm, etc.
Scaffold screw jack height is customized. You can choose the screw jack max adjusting height. You can also require the overall height of the scaffold screw jacks.
For construction scaffolding safety, the scaffold screw jack nut is always stopping at 150mm from the top (or 1/4 of overall height) to avoid running out in scaffold working.
There are many types of scaffolding jack nuts. Include:
Among them, the cast iron type of jack nut is the most required. The reason is
Cast steel and drop forged screw jack nuts are more expensive in cost than cast iron ones. In addition, the inner screws of the screw jack nut need a machinery threading.
According to the scaffold screw jack nut weight, there are light, heavy, and medium weight screw jack nuts.
Scaffold screw jacks are able to be finished in painted, zinc-plated (cold galvanized), or hot-dip galvanized. Hot-dip galvanized(HDG) scaffolding jacks are the most durable in long-term use.
According to the threaded way of the screw jack scaffolding, you can find square threaded and round threaded scaffolding screw jacks in Wellmade.
Square threaded scaffold jacks are with 6.35mm (4 TPI – four teeth per inch) teeth distance. While the round threaded scaffold jack is with 8mm teeth distance.
According to the teeth distance, we called round threaded scaffold jack base coarse threaded jack scaffolding, or quick threaded scaffolding jack stand.
Wellmade quick threaded screw jack bases are popularly used in Europe and Australian markets for the following features:
Wellmade scaffold screw jack diameters are designed according to your scaffolding standards dimensions. Basically, the scaffolding screw jack’s diameter needs to be smaller than the inside diameter of the scaffolding poles. While the screw jack nut support circles must be bigger than the outer diameter of the scaffold vertical parts. Wellmade has professional engineers to help you design the correct scaffold screw jacks for your construction.
The scaffolding screw jacks’ load capacities are different at different heights. Wellmade always gives you ideas about your scaffold screw jack load weight by real test in our test house.
Wellmade is a professional scaffold screw jack supplier in China. We manufacture different types of scaffolding screw jacks according to your scaffolding construction.
As adjustable scaffolding leveling stands, there are basically two types of scaffold screw jacks: the bottom type of scaffold screw jacks and the top type of screw jack scaffolding. Bottom scaffold screw jacks are used at the bottom of the scaffolding in construction. While top screw jacks are used at the top of the scaffolding to support slabs, beams in concrete formwork, and shoring system.
Bottom scaffolding screw jacks are called adjustable jack base or base jacks. It is fabricated with threaded screw jack stems, scaffold jack nut, and base plate. Among them, the jack nut is adjustable handles. It makes the screw jack base run to different levels.
In the construction, it is used as feet of the scaffolding in construction. Adjustable screw jack bases are used popularly in uneven construction ground. It is easy to adjust the scaffolding horizontally at the same level. Thus, the scaffold jack base is also called bottom screw jack scaffolding or leveling jacks, leveling feet, etc.
During the scaffolding level adjusting, you can use the scaffold evens to measure the horizontal level. The same level of scaffolding material is the base regulation of scaffolding construction. It ensures your scaffolding tower safety and stable.
Top type scaffold screw jacks are placed at the top of the scaffold towers during the construction. It is required a lot in shoring scaffold system support, including slab formwork support, beam formwork structure support, etc.
In the shoring scaffolding system, top head scaffold screw jacks are used as scaffold connectors between the scaffold and concrete formwork beams. You can find the top head scaffold screw jacks are able to work with all types of formwork beams. Include timber beams like h20 beam, steel formwork beams like steel hollow section, and aluminum beams like aluma, etc.
At the same time, the top head scaffold screw jack is compatible with all formwork systems, Including steel, steel -ply and aluminum formworks in the slab and beam concrete.
According to the top head screw jack types. You can find the following types of scaffold top head screw Jacks here:
More than jack base and top head screw jacks, there are other 2 types of screw jacks in scaffolding. One is a universal jack, another one is a swivel jack base.
The universal jack is a type of scaffold screw jack without the base plate or top head. When it joins with a fixed base plate, it will be a scaffold base jack. While you can use the universal screw jack joint with a fixed U head, then a top head scaffold screw jack is formed.
A swivel screw jack is a type of jack base. Different from normal fixed scaffold jack base. the swivel screw jacks are used on a sloped(inclined) basis.
Bar screw jacks are also called solid scaffold jack stands in scaffolding. While tubular scaffold screw jacks are called hollow-type screw jacks.
In fabrication, bar screw jacks are made from round bars. According to the diameter of the solid scaffold jacks, there are OD26mm to OD48mm.
Hollow-type scaffold screw jacks are manufactured by scaffold tubes(round steel pipes). According to the steel raw material, there are seamless scaffold screw jacks and seam (welded tube) scaffold screw jacks.
Scaffold screw jack with socket base plate includes two parts. One is a universal jack, another one is a socket base plate. Between the universal jack and socket base plates, there is a bolt or rivet to fix them well.
There are two types of scaffold screw jack with socket base plates. One is OD48mm for Crab 60 shoring system. Another one is OD38mm for the slab cuplock formwork system.
The OD48mm socket plate screw jacks are the leveling feet for OD60mm Crab 60 scaffolding standards. While cuplock scaffolding screw jack with socket plates are able to be used at the top of cuplock standard to connect with the cuplock formwork system drop head and decking beam.
The socket scaffold screw jacks are able to be hot-dip galvanized, E-galvanized, or painted.
In the heavy-duty scaffold shoring frame system, you can use scaffold screw jacks with a washer lock. The washer lock scaffold screw jacks are always in OD48mm diameter for OD57 or OD60mm scaffold poles.
Adjustable scaffolding wheels are a set of scaffolding parts integrated with a scaffold castor wheel and a scaffold leveling jack base.
You can ask for rubber type, plastic-type, PU type, or cast steel type scaffolding wheels. While the scaffold jack base types and sizes are customized according to your construction request too.
Adjustable scaffolding wheels are used a lot in movable and mobile scaffold systems and towers. Wellmade offer you 5″, 6″, 8″, 10″, and 12″ adjustable scaffolding wheels for your lightweight and heavy-duty work.
Wellmade Manufactures Standardize Scaffold Screw Jacks. We also offer Customized Scaffold Screw Jack for Your Special Requirement.
According to Scaffolding Systems, Wellmade’s Scaffold Screw Jack Threaded Diameter Would be OD26mm to OD 48mm.
Wellmade’s Scaffold Screw Jack can be Zinc-plated ( E-galvanized) or Hot Dip Galvanized for Different Durable Requirements and Construction Project Budget plans.
Our Scaffold Screw Jacks are Popular Used In All Constructions and Buildings: Onshore and Offshore Construction, Civil Construction, Industrial and Commerical Construction.
Scaffold screw jack sizes are always customized in diameters, adjustable height, overall height, base plate, u head, and forkhead sizes, etc.
The most used scaffold screw jack includes 24″ scaffold jacks, 1-3/8″ and 1-1/4″ scaffold screw jacks. Both of them are used as scaffold stands or scaffold feet of the scaffolding poles.
Scaffold screw jack steel grade is mostly S235. While you can ask for C45 steel or S355 steel grade if needed.
