Multiprops

PERI MULTIPROP Props can be used as individual props and in combination with the Frame MRK as a table or tower. The outer tube of the MULTIPROP prop is powder coated. The Frame MRK can be mounted on both the outer and inner tube. The integrated measuring tape and free-running collar allow accurate and fast height adjustment. The MULTIPROP prop has a fail-safe feature which prevents the inner tube from unintentionally slipping out. Markings on the outer tube facilitate the exact assembly of the MRK Frame. For any assembly work, only a hammer is required.

Technical Data For permissible load-bearing capacities, see type tests and PERI charts. Intended use 1. PERI products are exclusively technical working materials which are intended for commercial use by technically competent users only. 2. This assembly instructions serve as the basis for the project-related risk assessment and the instructions for the provision and use of the system by the contractor (user). However, they do not replace these. 3. Only PERI original components may be used. The use of other products and spare parts represent a misapplication with associated safety risks. 4. The components are to be inspected before each use to ensure that they are in perfect condition and function correctly. 5. Changes to PERI components are not permitted and represent a misapplication with associated safety risks. 6. Safety instructions and permissible loads must be observed. 7. Components provided by the contractor must conform with the characteristics required in these assembly instructions as well as all valid construction guidelines and standards. In particular, the following apply if nothing else is specified: – timber components: Strength Class C24 for Solid Wood EN 338. – scaffold tubes: galvanised steel tubing with minimum dimensions Ø 48.3 x 3.2 mm according to EN 12811- 1:2003 4.2.1.2. – scaffold tube couplings according to EN 74. 8. Deviations from the standard configuration may only be carried out after a separate risk assessment has been done by the contractor (user). On this basis, appropriate measures for the working safety and stability are to be implemented. 4 Assembly Instructions for Standard Configuration MULTIPROP System Introduction Safety instructions Additional PERI product information – type test for MULTIPROP individual props – type test for the MULTIPROP system – type test for the MULTIPROP individual props with Base MP 50 – type test for the MULTIPROP system with Base MP 50 General 1. Deviations from the standard configuration and/or intended use present a potential safety risk. 2. All country-specific laws, standards and other safety regulations are to be taken into account when are products are used. 3. During unfavorable weather conditions, suitable precautions and measures are to be taken to guarantee working safety and stability. 4. The contractor (user) must ensure the stability throughout all phases of construction. He must ensure and verify that all occuring loads are safely transferred. 5. The contractor (user) has to provide safe working areas for site personnel which are to be reached via safe access means. Areas of risk must be closed off and marked accordingly. Hatches and openings on accessible working areas must be kept closed during working operations. 6. In order to ensure better understandability, detailed descriptions are partly incomplete. The safety installations which have possibly not been shown in these detailed descriptions must nevertheless be available. Storage and transportation 1. Do not drop the components. 2. Store and transport components so that no unintentional change in their position is possible. Detach lifting gear from the lowered units only if these are in a stable position and no unintentional change is possible. 3. When moving, components are to be picked up and set down so that any unintentional toppling over, falling apart, slipping or rolling are avoided. 4. Use only suitable load-carrying equipment to move the components as well as the designated load-bearing points. 5. During the lifting and moving procedure, ensure all loose parts are removed or secured. 6. During the moving procedure, always use a guide rope. 7. Move components only on clean, flat and sufficiently load-bearing surfaces. System-specific 1. Retract components only when the concrete has sufficiently hardened and the person in charge has given the goahead for striking to take place. 2. Anchoring is to take place only if the anchorage has sufficient concrete strength. – PERI design tables – Instructions for Use for trolley and winch unit – Instructions for Use for pallets and stacking devices The structures presented in these assembly instructions are shown in the form of examples with only one component size.
