Professional wire tensioning unit for the production of prestressed concrete

The modern construction industry requires the implementation of materials that simultaneously reduce contractor costs and improve the operational characteristics of finished facilities. Prestressed concrete is the optimal solution to this business challenge. This building material is massively used worldwide and has become an industry standard in Ukraine and CIS countries over the past decades. A key element of the technological process at precast concrete plants is the wire tensioning unit. It is this specialized equipment that compensates for the natural inability of concrete to withstand significant tensile stresses, multiplying the strength and durability of the final product.

The essence of prestressing technology and the role of specialized hydraulic equipment

The main distinguishing feature of manufacturing prestressed concrete products is the preliminary laying and stretching of steel reinforcement. A reliable wire tensioning unit stretches the metal strands or rods to strictly specified parameters, after which the concrete mixture is poured over them. Once the concrete has finally set, the reinforcement is released. At this moment, the tension force is transferred to the concrete mass, artificially compressing it and keeping it in this state. The created compressive stress allows the manufacturer of the reinforced concrete product to completely avoid destructive tensile stress during operational loads.

Depending on the technical equipment of the enterprise, reinforcement tensioning equipment can carry out the process in several ways: mechanical using a hydraulic jack, electrothermal by heating the metal with current, and a combined electro-thermomechanical method.

Industrial application of prestressed concrete in modern commercial development

Today, prestressing technologies cover almost all areas of capital construction. The method is actively implemented in the construction of residential buildings, commercial offices, large-scale production shops, warehouses, and spacious retail areas. The use of powerful rebar tensioning systems allows for the creation of structures with uniform strength that can span huge distances without additional supports. This opens up limitless possibilities for architects: the absence of the need for frequent internal partitions allows for free space planning and flexible variation of building contours in a horizontal section for any customer tasks.

Key economic and technical benefits of prestressed structures for business

The implementation of prestressing technology brings measurable commercial benefits to manufacturing and construction companies:

• Saving reinforcing materials: A modern wire tensioning unit makes it possible to reduce metal consumption by 50%, which proportionally reduces the overall material intensity of construction by up to 27%.
• Reducing the weight of erected buildings: The use of prestressed elements allows reducing the total weight of the finished structure by 40%, which significantly reduces the critical load on the foundation.
• Increased strength and seismic resistance: The concrete’s resistance to cracking increases by 2-3 times compared to non-prestressed structures. Buildings become more resilient to regular loads and safer in zones with high seismic activity.
• Increasing overall profitability: From an economic point of view, development projects made of prestressed concrete demonstrate high profitability, bringing 35% more net profit from sales compared to traditional construction methods.

Reliable European equipment for stable production of reinforced concrete products

The stable output of high-margin reinforced concrete products requires fail-safe European equipment. The Finnish company TDM Engineering Oy supplies proven solutions from the German concern Paul Maschinenfabrik directly from the warehouse.

Our range includes mobile hydraulic power packs, tensioning jacks for wire and multi-wire strands, as well as reliable anchor grips of open type “A”, closed type “F”, and coupling chucks of type “K”. The jacks differ in variable tensioning force, working stroke, and the number of simultaneously tensioned rods.
