The Kwikstage Solid Base Jack is a heavy-duty leveling component designed to provide stable support for scaffolding uprights on uneven surfaces. Constructed from cast iron with a hot-dip galvanized base plate and a threaded steel adjusting screw, this base jack offers superior load-bearing capacity and height adjustability. The solid steel screw (M30 diameter) allows precise height correction up to 200mm, while the 250x250mm base plate distributes load evenly across soft or irregular ground.
Exceptional Load Capacity: Rated for 50kN static load, with a safety factor of 4:1, making it suitable for heavy-duty industrial scaffolding.
Fine Adjustment: The 5mm pitch screw allows height increments of 2.5mm, enabling precise leveling for platforms requiring strict horizontal alignment.
Anti-Rotation Design: A keyway slot in the base plate prevents the screw from rotating during adjustment, enhancing user safety and efficiency.
Ideal for projects requiring ground-level stabilization, the Solid Base Jack is used in:
1. Construction sites with uneven terrain or soft soil
2. Temporary scaffolding on asphalt or grass surfaces
3. Industrial scaffolding around machinery pits or drainage channels
4. Bridge scaffolding requiring adjustable support for varying pier heights.
Q: Can the base jack be used on concrete floors?
A: Yes, the flat base plate works on hard surfaces, though anchoring is recommended for high-wind areas.
Q: What is the minimum height setting?
A: 150mm (fully retracted), with maximum extension to 350mm. Custom lengths available on request.
Q: How to prevent screw jamming in wet conditions?
A: Apply a light grease to the threads and wipe clean after use. Avoid over-tightening when the base is loaded.
Q: Is it compatible with all Kwikstage uprights?
A: Yes, fits all 48.3mm OD uprights with standard base plate sockets.
