Scaffolding hollow jack is a key leveling component applicable to various scaffolding systems, including coupler-type steel tube scaffolding and ringlock scaffolding. According to its structural characteristics, it is mainly divided into four types: solid base jack, hollow base jack, U-shaped jack, and standard-type jack. This component has a standard length ranging from 300mm to 1000mm. By rotating the adjusting nut, precise height adjustment can be achieved, which effectively solves the problem of scaffold stability caused by uneven construction sites.
Scaffolding Hollow Jack
Description:
Scaffolding hollow jack is a key adjustment device ensuring the safety of scaffolding construction. As a core component connecting the ground and the scaffolding structure, its performance directly affects the stability of the entire support system. This component is made of high-quality Q235B carbon steel. A 4mm-thick square base plate (with standard sizes of 150×150mm or 200×200mm) is welded at the bottom, and the surface of the base plate is provided with anti-slip to enhance friction. Through a precision-machined trapezoidal thread transmission mechanism (with a pitch of 8mm), combined with an adjusting nut forged from steel, precise lifting adjustment can be realized, with an adjustment accuracy of ±1mm. Its innovative double-nut anti-loosening design can effectively prevent thread slippage caused by construction vibration. It is widely used in construction, bridge engineering, and other fields, making it an ideal choice for ensuring safety, improving efficiency, and reducing costs in modern building construction.
