What is Base Jack?

Scaffolding screw base jack base is made of screw tube and sheet metal plate, and assembled with casted nut. The application is support scaffolding system, ringlock scaffolding system, cuplock scaffolding system, kwikstage scaffolding system, haki scaffolding system, tube&clamp scaffolding system and also formwork system, adjusting the construction system height flexibly.

Construction is usually carried out at a height above the ground. Scaffolding is used to provide a stable and secure working platform for construction workers on the ground or where ladders or lifting devices cannot reach. 

Scaffolding is usually considered a temporary structure entered by internal or external workers. Many workplaces are uneven, and scaffolding adjustable base jacks help to provide a safe and level working surface at a variety of working heights on the ground.
A base jack is a scaffolding base jack used to hold scaffolding in place horizontally. The adjustable screw jack is mounted on a stable base and contains a large adjustable screw for moving scaffolding up and down. After scaffolding is built, use base jack scaffold to level the working platform before use. Adjustable U-Head Jacks are designed to be used in conjunction with adjustable system scaffolding. The main function of adjustable U-Head jack is to hold timber beams securely in place.

Base Jack Classification:

♦ The base jack is used at the bottom of the vertical steel rod and the bottom plate is at the bottom. The bottom plate can be folded or not folded.

♦ According to the lead screw material, can be divided into hollow base jack and solid base jack.

♦ The screw of hollow base jack is made of thick wall steel pipe, which is light in weight.

♦ The base of solid base jack adopts round steel bar, which is heavy in weight.

Scaffolding hollow adjustable base jack made by high strength steel structure in hollow tube diameter 35/38/48mm with screw thread. Usually used at the bottom of scaffolding system verticals, it makes the whole scaffold system more stable.

Scaffolding adjustable U-head jack is designed for use in combination with adjustable system supports. The main function of the Scaffolding adjustable U-head jack is to hold the wooden beam in place. The Scaffolding adjustable U-head jacks we offer are of high quality standard, and these have a pure zinc plated finished, thus adding to its gloss. These are all adjustable and therefore the greatest advantage of these products. This was done under the scrutiny of experts, thus ensuring superior performance.

Scaffolding base plate is a type of footplated for scaffold system and tube&clamp scaffolding. The spigot for scaffolding base plate can be made from round rod or scaffolding hollow tube. The size of scaffolding base plate can be divided into 50mm, 110mm, 120mm, 140mm, 150mm and so on according to EN74 / BS1139 standard and can customize according to your requirements. Depending on the usage and size of spigot, scaffolding base plate can be in insert type and socket type.

If the building is built on expansive soil, therefore, with regular movement, a scaffold screw jack can replace concrete piers between solid wood columns and girders that support the floor joists.

A scaffolding base jack is a metal support column that can be adjusted to make the floor level. It consists of two heavy steel tubes, one inside the other. The inner tube is threaded and adjusted up and down by turning a large wing nut. Screw jacks are fixed with nails to the underside of the girder and to wooden blocks on top of the concrete wharf.

1. In this process a hydraulic jack and a short column are used to support the floor.

2. Use hammers, nail pullers and sledgehammers to remove existing supporting posts and nails.

3. Place the scaffolding adjustable screw jacks under the beams and the wooden blocks on the concrete piers in the middle.

4. Adjust the scaffolding screw base jack so that the top and bottom panels are flush with the top and bottom wood surfaces.

5. Drive the 16 -penny nail through the hole in the plate and into the wooden frame.

6. Lower the hydraulic jack and transfer the floor load to the new scaffolding screw jack.

7. Adjust the adjustable base jack scaffold up and down to make the surface smooth.

The base jack scaffold is widely used in combination with scaffolding systems for building, hall, bridge, high-rise building inside and outside the row of scaffolding, used for electromechanical installation, hull construction, decoration engineering activity platform, building a simple roof, temporary site dormitory, warehouse, temporary observation platform, etc.
