Swivel Screw Jack

In heavy industrial and commercial construction, achieving a perfectly plumb scaffolding tower on sloped surfaces, bridge embankments, or staircases presents a severe engineering risk. The adjustable swivel screw jack sits at the absolute baseline of your scaffolding grid, acting as the primary load-bearing screw jack that adapts dynamically to inclined topography. Standard solid flat screw jacks fail on sloped ground because an angled footprint induces devastating bending moments on the vertical standards; our specialized articulating screw jack solves this problem completely by absorbing angular forces and transferring loads purely along the vertical axis.

Comprehensive Size Matrix (Engineered for Exact Slope Adaptation)

Worksite gradients demand precise clearances to ensure scaffolding runs remain completely level without exposing an unsafe length of thread on the screw jack. We manufacture a comprehensive matrix of exact-fit sizes to accommodate various slope angles and elevation shifts:

Unmatched Engineering & Structural Advantages:

• 0 to 45-Degree Pivot Articulation: Engineered for highly complex civil topographies, every SRE swivel screw jack features a heavy-duty, high-shear pinned hinge mechanism. This allows the screw jack base plate to pivot smoothly up to 45 degrees, matching the exact slope of the terrain while maintaining a rigid, perfectly vertical stem orientation.

• Thickened Footprint Load Distribution: Our screw jacks are welded to a thick, cold-rolled 150mm x 150mm x 5mm MS base plate. This expansive footprint evenly disperses massive vertical load pressure across mud-sills, preventing screw jack slippage and ground gouging.

• Precision-Machined 4TPI Threads: Safety and assembly speed must go hand-in-hand. The high-efficiency 4TPI (Threads Per Inch) pitch allows field crews to make rapid, millimeter-perfect height adjustments to the screw jack while maintaining maximum thread-to-nut friction and load-bearing lock capacity.

• Customizable Jack Nut Metallurgy: To match your specific project budgets and weight requirements, we supply every screw jack with either Forged Jack Nuts for extreme impact resistance and heavy-duty industrial shoring, or Casted Jack Nuts for reliable, cost-effective performance on standard commercial scaffolding setups.

Step-by-Step Screw Jack Installation Efficiency (Designed for EPCs):

Time on site directly impacts overall project margins. The SRE Swivel Screw Jack is engineered to eliminate field friction. Erection crews simply position the articulating screw jack base plate flat against the sloped ground or timber sill, insert the 4TPI solid threaded stem into the vertical standard tube, and rotate the heavy-duty nut to level the bay. The self-cleaning thread geometry on the screw jack easily sheds mud, scale, and concrete slurry, ensuring smooth, rapid adjustments over years of continuous field rotations.

📦 Bulk Procurement & Global Export Supply

SRE understands the intense logistical demands of utility-scale infrastructure projects and large rental fleets. Every Heavy-Duty MS Swivel Screw Jack undergoes rigorous batch testing for pivot fluidness, thread accuracy, and weld strength before being prepared for transit. We offer highly competitive, tier-based wholesale pricing structures for major domestic EPC contractors, alongside robust, palletized packaging configurations engineered to deliver your screw jack orders globally with zero damage.
