Bundling, Forklift Stillage & Container Top-Up Specs
Adding 20–50 articulated swivel jacks inside standard facade container packages is a smart upgrade for hilly urban regions (Istanbul, Switzerland, coastal Mediterranean).
Structural Engineering Details, Fleet Compatibility & Field Performance
Eliminating Eccentric Spindle Bending on Steep Slopes
When a fixed base jack rests on slopes steeper than 5%, only one edge of the plate touches the ground, inducing dangerous bending moments in the threaded rod. Our articulated U-yoke seats the entire plate flat on the slope while keeping the Ø38 mm spindle dead plumb.
4-Corner Anchor Bolting Against Down-Slope Sliding
Sloped bearings generate horizontal shear forces along the ramp surface. Four corner holes in the swivel plate accept SM-K541 M10×75 concrete screws to lock each foot positively against downhill slip.
Pitched Roof Towers, Bridge Abutments & Heritage Terraces
Ideal for heritage spire restorations perched on sloped roofs, bridge abutment formwork, and terraced hillsides where timber wedge shimming is prohibited by HSE engineers.
