Scaffolding U-Head Jack

Scaffolding U-Head Jack,also known as adjustable support,is a core accessory used to adjust the height of the scaffolding,support heavy objects and balance the structure in building construction.

Here's a closer look:

Structural composition

It is composed of three parts:chassis,lead screw and adjustment nut.Some models also come with stiffeners,sliding collars and splint systems,among others.

classify

According to the use part:it can be divided into upper support,bottom support and pipe support.The upper support is used at the upper end of the column steel pipe,and the chassis is at the upper end and has folded edges;The bottom support is used at the lower end of the column steel pipe,and the chassis is in the lower part,which can be without folding edges;The tube buttocks were stuck on parallel steel tubes and the chassis had half-moon notches.

According to the lead screw material:it can be divided into hollow top support and solid top support.The lead screw of the hollow top support is made of thick-walled steel pipe,which is lighter in weight;The lead screw of the solid top support is made of round steel and is heavier.

According to whether it has wheels or not:it can be divided into ordinary top support and leg wheel top support.The wheel top support is generally galvanized and used for the lower part of the movable scaffolding,which is convenient for pushing;Ordinary top support is used in engineering building construction and has stable support.

Specifications

Lead screw diameter:Φ28,Φ30,Φ32,Φ35,etc.(solid top support),and the diameter of the hollow top support is generallyΦ32-Φ48mm.

Lead Screw Length:Usually between 400-700mm.

Chassis size:Specifications and manufacturers vary from place to place.

Load capacity:single-point static load-bearing≥20kN(ordinary type),reinforced type can≥50kN.

use

It is used in conjunction with steel pipes and scaffolding during the construction process,which plays a role in adjusting the height of scaffolding and pipe frames,balancing the support of heavy loads,and bearing the load.
