In the modular scaffolding system, the Scaffold U Jack is a crucial adjusting component, and the selection of U Head Jack Size (U-type head size) directly affects construction safety and support efficiency.
Why is size important?
The size of the U-shaped head determines the contact area with the wooden beams and steel beams. A too-small U-shaped head may cause concentrated force and the crushing of the wooden beams; a too-large U-shaped head may make installation difficult or cause interference with the crossbars. Our U Head Jack uses 4-5mm thick-walled steel pipes. The U plate offers multiple sizes and thickness options, and can be welded with 2-4 triangular reinforcing ribs, significantly enhancing the structural stability under heavy-load conditions.
Product Core Advantages
Steel Scaffolding Screw Jack is a multi-functional adjustable component. It is installed on the top of the scaffolding to support the cross beams. It is composed of a screw rod, a U-shaped plate and a locking nut. To meet high load requirements, some models are welded with triangular reinforcing plates at the U-shaped head to prevent deformation.
This jack offers both solid and hollow types of screw rods, and is widely used in engineering and bridge construction. It perfectly integrates with mainstream modular systems such as Ringlock, Cuplock, and Kwikstage. It also serves as both a lifting support and a base support, achieving the dual functions of one item.
