RMD Kwikform has launched Tetrashor, a lightweight modular propping system that can deliver a loading capacity of up to 400 kN. The system has been designed for the building refurbishment and civil engineering markets, finding applications in dead shoring, façade retention, propping and needling, supporting precast concrete bridge beams and structural steelwork frames and restraining tall single and double-sided formwork.
The system’s 400 kN loading capacity means a minimum number of props are required, helping to reduce costs and assembly time for contractors. At the same time, it has been designed with lightweight components, so the product can be easily carried about by workers, without the need for a crane. With a weight of only 30 kg/m, Tetrashor delivers an excellent strength-to-weight ratio.
Tetrashor’s versatility is a key feature. It can be used horizontally, vertically and inclined. The Tetrashor prop can also be used as a group of four to create a Tetrashor tower, providing a loading capacity of up to 1600 kN for heavy, concentrated loads. Tetrashor is compatible with RMD Kwikform’s market leading range of falsework systems too, including Megashor, Rapidshor and Superslim.
The system also features an innovative ‘KwikStrike’ load release mechanism, so workers can release loads in a quick and controlled manner. Testing has proven that activating KwikStrike requires only two or three hits from a hammer; removing loads can be a long and exhausting process with other systems. Not only does this help to reduce labour, effort and time, but it minimises noise, safety risks and damage to equipment too. A range of hydraulic jacking options are available with Tetrashor, enabling the controlled application, monitoring and release of loads should the application demand precision.
Available in five different prop variants to suit most applications, Tetrashor offers a strong and assured propping solution, while still meeting the contractor’s need for a system that can be easily manoeuvred about on site.
