U Head Jack
Key Selling Points

U Head Jacks are critical accessories for modern scaffolding and formwork systems, offering strength, adjustability, and versatility. One of their main advantages is the U-shaped head design, which provides a secure resting point for beams, ledgers, or planks, ensuring that supported structures remain stable during construction or maintenance work.


The adjustable screw mechanism allows precise vertical height adjustment, enabling quick leveling on uneven surfaces or during formwork setup. This feature improves operational efficiency and reduces labor effort while maintaining safety standards.


Durability and load-bearing capacity are key strengths. High-quality U Head Jacks are made from heavy-duty steel capable of supporting substantial loads, making them suitable for multi-level scaffolding, concrete formwork, and industrial maintenance platforms. Corrosion-resistant finishes, such as hot-dip galvanization or painting, ensure long-term use in harsh environments, including outdoor construction sites or humid conditions.


Safety is further enhanced through robust screw threads, wide base plates, and stable U-shaped tops, which prevent slippage or misalignment under load. U Head Jacks are compatible with various scaffolding and formwork systems, including frame scaffolding, Ringlock scaffolding, and modular formwork setups, offering versatility for different projects.


Overall, U Head Jacks combine strength, adjustability, safety, and durability, making them indispensable for engineers, contractors, and site managers who require reliable support for scaffolding and formwork applications.

Technical Parameters

U Head Jacks are manufactured to meet strict international safety and quality standards. Typical technical parameters include:


Material: High-strength steel

Screw Adjustment Range: 150 mm to 500 mm (varies by model)

Load Capacity: 3–5 tons per jack, depending on size and application

U Head Width: 100–200 mm (accommodates different beam sizes)

Base Plate Diameter: 120–160 mm for stability

Surface Treatment: Hot-dip galvanized or painted for corrosion protection

Compatibility: Frame scaffolding, Ringlock scaffolding, modular formwork systems

Type: Adjustable screw jack with U-shaped head and base plate


The adjustable screw allows fine vertical alignment, ensuring the supported beams or ledgers are level and secure. The wide base plate distributes loads evenly, preventing sinking or tilting on uneven surfaces. The U-shaped top accommodates beams, planks, or ledgers of different sizes, providing versatility across multiple scaffolding and formwork applications.


Regular inspection of the screw threads, U-head top, and base plate is recommended to maintain safety and structural integrity. Proper installation ensures secure load transfer and prevents deformation or tilting under heavy loads.

Product Knowledge

U Head Jacks are essential components for scaffolding and formwork support, designed to provide vertical load transfer and stable resting points for beams or ledgers. The U-shaped top ensures that horizontal elements, such as timber beams, steel ledgers, or planks, are securely held in place, reducing the risk of misalignment or slippage during construction.


The jack’s working principle combines adjustable height and load distribution. The threaded screw allows precise vertical adjustment to level structures, while the wide base plate spreads the load across the ground. The U-shaped head distributes weight evenly across beams or ledgers, ensuring structural stability for supported slabs, scaffold platforms, or formwork components.


Compared with standard base jacks, U Head Jacks provide enhanced versatility by accommodating horizontal elements of various sizes, making them suitable for slab formwork, beam support, industrial platforms, and temporary scaffolding setups. They are particularly valuable in high-rise buildings, bridges, industrial construction, and projects requiring multi-level formwork.


Durable construction and corrosion-resistant coatings ensure that U Head Jacks maintain performance in challenging environments. They are reusable across multiple projects, offering long-term cost-effectiveness. Proper installation, height adjustment, and routine inspection of threads and U-head tops are critical to ensure safety, stability, and optimal performance.


When used correctly, U Head Jacks provide safe, adjustable, and reliable support, improving productivity, reducing labor effort, and maintaining structural integrity across scaffolding and formwork applications.
