Adjustable U-Head Jack for Scaffold Shoring and Height Leveling

Heavy-duty U-head jack designed for precise height adjustment and load distribution in scaffolding systems, compatible with Ringlock, Cuplock, and tube-and-clamp setups.
Forged from Grade S355JR carbon steel with hot-dip galvanized coating (≥80μm), ensuring corrosion resistance for construction, industrial, and marine environments.
Dual-threaded screw mechanism provides ±150mm vertical adjustment range, supporting vertical loads up to 30kN with minimal deflection.
U-shaped saddle design securely holds scaffold beams, formwork, or steel plates, preventing slippage during concrete pouring or heavy equipment operations.

product details

Applications

Critical for vertical alignment and load transfer in scaffolding shoring systems for high-rise buildings, bridges, and tunnel construction.

Used to stabilize formwork during concrete casting, ensuring flatness and structural integrity in slabs, columns, and walls.

Deployed in industrial maintenance platforms, temporary event stages, and mezzanine floors requiring adjustable height support.

Technical Specifications

Design Advantages

Precision Adjustment: Acme-threaded screw with hexagonal nut allows fine-tuning (±5mm increments) for exact height alignment.

Anti-Slip Design: U-shaped saddle with serrated inner surface grips beams securely, even under dynamic loads.

Durability: Reinforced base plate and welded seams withstand repeated adjustments and heavy impacts.

Industries & Use Cases

Civil Engineering: Essential for bridge deck supports, precast concrete element installation, and seismic retrofit projects.

Industrial Construction: Used in steel mill maintenance, power plant boiler access, and shipyard dry dock scaffolding.

Event Infrastructure: Provides adjustable support for temporary stages, lighting towers, and exhibition hall flooring.

Quality Assurance

Rigorous testing includes load fatigue simulation (50,000 cycles), salt spray resistance (2,500 hours per ASTM B117), and weld penetration checks.

Certifications: CE, UKCA, ISO 9001:2015, and OSHA 1926.451 compliance.

OEM services for custom branding, bulk packaging, and technical drawings (AutoCAD/PDF formats).
