The screw jack is used as a starting base for a scaffold where the supporting surface of the scaffold is on a slope. Adjustable base jack enables accurate levelling of the scaffolding on uneven ground and infinite adjustment on sloping ground.
A screw jack, also known as a leveling jack or screw leg, plays the role of providing a steady and balanced foundation for your scaffolding platform. These jacks feature a fixed base plate measuring 4″ X 4″, which serves as a foot. To ensure stability, this base plate can be easily fastened to a wooden mud sill using nails or screws. The jacks offer the flexibility to raise the scaffolding platform by up to 12″, allowing for precise leveling.
Imagine these jacks as giant screws, where the scaffolding frame rests on a nut that can be adjusted by rotating it either clockwise or counter-clockwise. With a height of 18″, the jack extends approximately 6″ inside the scaffolding frame even when raised to the maximum 12″ position. To secure the jacks to the scaffolding frames, you can use either a toggle pin or a span pin.
Our jacks are crafted from durable steel and coated with Zinc to ensure resistance against rust. To meet the safety standards set by OSHA, we subject the jacks to rigorous testing. During our compression test, the scaffolding frames reached their limits at around 40,000 lbs, but the jacks performed exceptionally well and did not fail.
Scaffold screw jacks, also known as adjustable jacks, scaffold standards, scaffold screws, scaffold legs, scaffold jack supports, or jack scaffolding, serve as leveling legs for scaffolding, ensuring a stable and even scaffold platform.
Our GW EQUIP scaffolding screw jacks are highly versatile and can be used in various scaffolding systems, including ringlock system scaffolding, cuplock system scaffolding, kwikstage scaffolding, quick lock scaffold, scaffold tube and clamp system, shoring frame system scaffold, traditional frame scaffolding systems, ring shore system, crab 25, and crab 60 shore system, among others.
To enhance the durability of the scaffold screw jacks, we offer different options such as zinc plating (E-galvanized), hot-dip galvanizing (HDG), and painted finishes.
Rest assured, all our scaffold screw jacks undergo rigorous testing according to EN 12810 standard regulations to ensure their safety load capacity. Additionally, we provide the option for custom jack scaffolding manufacturing with your company logo and name.
