At this year's bauma, PERI provided significantly more space for showcasing the PERI UP scaffolding solutions in the specially designed 4,000 m² exhibition hall than was the case in 2010. The complete range of scaffolding applications was presented along with new system components and numerous further developments. The exhibition offered prospective customers the best opportunity to learn more about the proven and innovative technology as well as PERI services in greater detail. The entire week of the fair in Munich was characterized by an extremely positive feedback from the industry.
The wide range of exhibits provided scaffolding experts the perfect opportunity to intensively address the optimized solutions which are based on the very latest system technology and the best engineering capabilities. In addition to many live demonstrations, numerous visitors from home and abroad were delighted to have had the chance in particular to take part in technical discussions in with the PERI specialists - especially regarding PERI planning and services.
The positive feedback was overwhelming and the purpose-built PERI hall on the Open-Air Area North was extremely well frequented throughout the week. In addition to PERI´s scaffolding technical advisers, experts from all areas fielded a multitude of questions concerning PERI UP scaffolding technology: the team responsible consisted of the product managers, engineers with their vast experience in project planning and experts from logistics, training and development - through impressive product demonstrations and personal discussions, they provided numerous details and passed on specialist knowledge about the PERI technology and optimized planning solutions.
PERI provides overall concepts comprised of scaffolding systems, engineering and competent jobsite support with great emphasis being placed on cooperative partnerships with our customers. The diversity of feasible solutions using PERI UP was also very apparent during the week of the fair: access means for construction sites and public sector projects, flexible and adaptable working platforms for the industrial sector, movable suspended scaffolds, compact lattice girders for refurbishment contracts, facade scaffold with the guardrail in advance as well as the entire spectrum of shoring activities - all applications were presented, many of which included demonstrations. Live and hands-on was the motto and every user had the opportunity to become familiar with the technology on the specially prepared demonstration area. Safe and fast assembly and dismantling along with access options for a broad range of requirements was the main focus during the week. In addition, new system components were also presented for use in industry as well as for the LGS weather protection roof.
A new trolley is used to realize movable suspended scaffolds on steel girders. It is intended for suspended scaffolding which is mounted, for example, on the underside of oil platforms or bridges on I-shaped steel profiles. The trolley is suitable for flange widths ranging from 200 mm to 320 mm and flange thicknesses up to approx. 40 mm. The rollers are bearing-mounted and allow connections to inclined girders of angles up to 15°. The system spacings of the scaffold are retained when using the UFS trolley in spite of the variable distances between the steel girders: as the position of the standards vis-á-vis the girder axis can be continuously adjusted by up to 125 mm, this always results in system dimensions in 25 cm increments for the scaffold sub-structure.
The LGS lattice girder system has established itself as a reliable and easy-to-use lightweight weather protection roof - supplemented by components for support and ridge formation. For closing the scaffold construction with sheeting, PERI has now developed a considerably faster solution. In addition, the new brackets ensure that working conditions on the roof are much safer.
Closing the construction with sheeting is now much easier and faster because the optimized Keder tracks along with the new Keder couplings reduce friction and thus the amount of physical effort required. In addition, a new eave element with a radial gradient allows the sheeting to be pulled more easily together and tightly closed also in the support areas of the protection roof. Another new feature is that through the integrated smooth-running mechanism, the sheeting can be evenly pulled across the complete width on rollers. Through this new solution for the installation of the covering, transport of the Keder sheeting is also simplified.
Furthermore, PERI has developed new system components that ensure safe access to the protection roof. For this, the new brackets are mounted on the LGS element with 3.00 m spacings, whilst safe walkways along the truss girder are formed with proven UDI decks and standard guardrails. When working under the roof, the use of personal protection gear against falling is therefore not necessary. The pre-assembly of the brackets is carried out together with the roof segments on the ground - to a very large extent without tools. Then the complete units are lifted by crane into the required position. Access is possible through the load-carrying system and support construction.
Comprised of lightweight individual components, the steel ULS Flex lattice girder is primarily intended for those applications where the long length of single-piece lattice girders means installation cannot take place. The girder consists of five lightweight individual components with a maximum length of 1.50 m and a top weight of 15.4 kg. The quick and easy assembly with pins and cotter pins - without any tube coupling connections - makes the new lattice girder extremely practical for every construction site. Due to its compact dimensions and low individual weights, the ULS Flex system parts fit through narrow manholes and small freight elevators - an important aspect, for example, during renovation work in old buildings. The girder can be adapted in 25 cm increments and bridging lengths from 3.00 m to 9.00 m are possible.
PERI provides solutions to meet all requirements in shoring operations, from simple slab props through to spatial and heavy-duty falsework. 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. For the heavy-duty shoring, new systems have been developed in the past three years which have already been successfully proven at a number of job sites. Shortly after being showcased at the last bauma, the VARIOKIT heavy-duty shoring tower, for example, was successfully used in summer 2010 as shoring for bridge construction as well as for supporting extremely heavy precast concrete elements. This heavy-duty tower has now been complemented by a suitably matched heavy-duty truss girder.
Also presented for the first time was the MDS shoring tower which provides a very high level of safety during assembly and dismantling. During assembly, scaffolders work whilst standing in a safe position in the centre of the tower with the help of a newly developed platform. The PERI UP Rosett Flex MDS shoring tower is used in "classic" shoring operations with leg loads of up to 50 kN.
Also new is that the system components of the modular scaffolding can now also be used for heavy-duty props which is utilized for the safe transfer of concentrated loads of up to 200 kN. The middle section of the 4-leg support 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 support for the lifting cylinder of the hydraulic unit. The dedicated HD hydraulic unit allows a stroke length of 68 mm and 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.
