High-Quality Adjustable U-Head Jack for Scaffold Shoring and Height Leveling Manufacturer, Factory

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.
