Swivel Base Jack

Swivel Base Jack

1. Product Overview

Swivel Base Jack, also known as adjustable scaffolding screw base jack, is an essential bottom support component for ringlock scaffolding, frame scaffolding and all kinds of construction scaffolding systems. Made of solid Q235 steel with hot-dipped galvanized surface treatment, this adjustable screw jack is designed to level scaffolding on uneven ground, balance load bearing and stabilize the whole scaffold frame during building, bridge and engineering construction. The swivel square base plate can rotate freely to fit sloped floors, mud ground and rough construction sites, solving the leveling problem perfectly.

2. Key Structure

1. Threaded Screw Rod: Full-length trapezoidal thread, smooth rotation, large adjustment range, support customized lengths from 1.0m to 3.5m.

2. Swivel Nut / Wing Nut: Two-side butterfly nut for easy manual height adjustment without tools.

3. Rotatable Square Base Plate: Thickened galvanized steel base, 360° swivel design, evenly disperse heavy pressure, prevent sinking on soft ground.

4. Anti-slip Reinforcement Clamp: Reinforced positioning structure to lock the screw firmly, avoid slipping under heavy construction load.
