Rebar tensioning jack selection and use

A tensioning jack plays a key role in the construction of precast concrete products such as hollow core floor slabs. They ensure high quality and durability of the products through proper tensioning of the reinforcement. Among the most popular models on the market stand out PAUL jacks.

Features of PAUL jacks

PAUL jacks are used for tensioning wire, steel reinforcement and steel strands. They are used both in precast concrete factories and construction sites. These devices differ in tensioning force, working stroke and number of reinforcement bars to be tensioned simultaneously.

The main types of PAUL jacks, rebar tensioning device selection and use include:

• Single-hose mini jacks: designed for small reinforced concrete members and are easy to use.
• Two-hose jacks: equipped with a hydraulic wedge anchor to ensure reliable anchoring without release losses.
• Four-hose jacks: allow gripping, tensioning, locking and retracting with two buttons.

Choosing a jack

When choosing a rebar tensioning jack, it is important to consider the following characteristics:

• Purpose: for steel rebar, wire or ropes.
• Method of movement: stationary or mobile models.
• Type of attachment and fixing: depends on the specific tasks and working conditions.

PAUL jacks offer high performance and compliance with the specified parameters. Rebar tensioning device selection and use, provide uniform tension along the entire length of the rebar, which contributes to the quality and durability of precast concrete.

Use of PAUL jacks

For proper use of the jack, the manufacturer’s recommendations must be followed:

1. Connection to the hydraulic power pack: PAUL jacks work with NG50 hydraulic power packs or NG15 mini pumps.
2. Installation and fixing of the reinforcement: the reinforcement material is fixed in the jack and tensioned to the required force.
3. Anchoring and fixing: after tensioning, the reinforcement is fixed with anchoring products.

Advantages of PAUL jacks

There are many advantages to using PAUL jacks:

• High performance: fast and efficient tensioning process.
• Quality and reliability: ensures even tensioning of the rebar.
• Convenience in work: compact size and ease of operation.

TDM company offers a wide range of PAUL jacks, the device for tensioning reinforcement the choice and use, which meet the highest standards of quality and efficiency. When selecting equipment, it is important to consider all the specifications and requirements of a particular project to ensure the best possible quality and long-lasting results.

Choosing the right rebar tensioning jack is the key to successful performance of production work and long service life of reinforced concrete structures.
