Base Jack Manufacturer

Scaffolding base jack 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.

Base Jack is usually considered a temporary structure entered by internal or external workers. Many workplaces are uneven, and adjustable base jacks help to provide a safe and level working surface at a variety of working heights on the ground.
A scaffolding leveling jacks is a base jack used to hold scaffolding in place horizontally. The scaffolding leveling 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 scaffolding 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.

These are all adjustable and therefore the greatest advantage of these products. This was done under the scrutiny of experts, thus ensuring superior performance.

 

The dimensions of a U-Head Jack must match the width of mainstream beams (such as wooden or aluminum beams):
Standard Width: Commonly 150mm or 170mm.
Side Wing Height: Typically 100mm or 150mm, used to prevent the beam from slipping under load.
Steel Plate Thickness: Core standards require between 6mm and 8mm to prevent deformation under heavy loads.

The socket base jack (also known as an adjustable socket base jack or sleeve-type base jack) is primarily used at the base of construction scaffolding and heavy-duty shoring systems (such as ringlock, cuplock, and frame scaffolding).
Its key feature is a sleeve welded onto the base plate; the threaded rod allows for height adjustment via a nut, while the sleeve provides a guided connection for the scaffolding upright. This effectively prevents lateral displacement at the base of the upright, significantly enhancing the shoring system's resistance to overturning and its overall stability.

The base jack scaffolding 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.

 

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

A scaffolding leveling jacks 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. scaffolding screw jack 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 scaffolding screw jack 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 scaffolding jack up and down to make the surface smooth.
