Jack base
Jack base refers to an adjustable base plate that is used to provide a stable and level foundation for the scaffold. It is typically placed at the bottom of the scaffold's vertical standards (or uprights) and is adjustable in height to accommodate uneven ground or floor surfaces. The jack base allows for precise leveling of the scaffold, ensuring that it is stable and secure during construction or maintenance activities.
The adjustable nature of the jack base makes it a versatile component in frame scaffolding systems, as it can be used to compensate for variations in ground elevation and provide a solid footing for the scaffold structure. This helps to enhance safety and stability, particularly when working on uneven or sloped surfaces.
Adjustable screw jack base can be used in engineering construction, bridge construction, and used with all kinds of scaffold, play the role of top and bottom support. The surface treatment :hot dip galvanized or electro galvanized . Head base is usually U type,the base plate is usually square or customized by customer.
