PERI provides solutions to meet all requirements for shoring systems, from simple slab props through to spatial load-bearing scaffolds – and always compatible with PERI slab formwork systems. Here, too, further potential for improvement was fully exploited – for example, improving the ergonomics and safety, increasing the load-bearing capacity as well as the development of new areas of application.
PEP Ergo: tubular steel props with maximum load-bearing capacity and practical details
The PEP Ergo range of props has been supplemented by five additional tubular steel props. This includes the PEP Ergo E-300 and PEP Ergo E-400 which feature an unprecedented load-bearing capacity for tubular steel slab props of up to 50 kN. The props are characterized by their low self-weight and through numerous, intelligent detailed solutions. For example, the easy loosening of the nut through the innovative G-hook, a large adjustment range of 12 cm, the integrated safety clearance, the triple-winged nut with hardened bearing surface and the stamped measuring tape. In total, the product group´s nine props now optimally cover the complete range of applications for daily construction site operations with a minimum of different prop types.
PERI UP Rosett Flex heavy-duty props: the new heavy-duty prop comprised of lightweight system components with hydraulic lowering and prestressing
The system components of the PERI UP Rosett Flex modular scaffolding can now also be used for heavy-duty props. The middle section of the 4-leg suppport consists of standard system components of the modular scaffold. New components are head and lowering spindles as well as a connecting plate. The TR head spindle has an adjustment range of 55 cm while the HD lowering spindle is used as a base spindle and serves as a housing for the lifting cylinder of the hydraulic unit. The UJC connecting plate transfers the forces from the prop into the lowering spindle. The dedicated HD hydraulic unit allows a stroke length of 68 mm.
The heavy-duty prop is used for the safe transfer of concentrated loads of up to 200 kN. These loads occur in shoring as well as for building redevelopment. The hydraulic cylinder in the base allows the deformation-controlled lowering of the props in 10-mm increments and the torque-controlled lowering of props under load by reading off in kN on the manometer. Likewise, the hydraulic allows the systematic, torque-controlled pre-tensioning of the prop up to 200 kN which is required for shoring in reconstruction projects. All components can be transported by hand, and using standard system components to the greatest possible extent makes the solution extremely cost-effective.
PERI UP Rosett Flex: the MDS shoring tower with integrated safety
On the basis of the PERI UP shoring system and supplemented by a few additional components, PERI has developed a shoring tower which provides a very high level of safety during assembly and dismantling. For assembling the MDS shoring tower, scaffolders work whilst standing in a safe position in the centre of the tower with the help of a newly developed platform. This platform is the key element during the assembly because it accelerates the handling while at the same time providing delivering a high degree of safety as all levels of the shoring tower are assembled and dismantled with protection automatically provided by a guardrail in advance. The MDS shoring tower can only be extended upwards if the leading platform has been suspended on the next higherpositioned ledger. As a result, the scaffolder is secure during every stage of the assembly without requiring any additional anti-fall equipment. In addition, the supply of materials is carried out safely inside the tower. The PERI UP Rosett Flex MDS shoring tower is used in "classic" shoring operations with leg loads of up to 50 kN. In the direction of the frame, the width is 125 cm; in the longitudinal direction, the dimensions can be freely selected in accordance with the static and geometrical requirements. Furthermore, all other system components of the PERI UP Rosett Flex modular scaffolding can also be used.
