The steel structure is completely hot-dip galvanized. A high adaptability to given structures can be achieved by project-related assembly of the climbing scaffold units. Wall formwork and brackets are connected together to form complete units to be shifted by crane. Owing to the move-off carriage on the CS 240 L bracket, the formwork can be retracted up to approx. 8 cm (depending on type of formwork). The formwork may also be tilted by means of a separate tilting device. All required fair-faced concrete finishes can be realized by using the proper type of 2 formwork (either frame panel or timber beam wall formwork). Depending on the width of the scaffold, the Climbing System is applicable to heights of more than 100 m over ground and allows a maximum formwork height of up to 5.40 m. The application is based on vertical formwork on both sides of the concrete to be placed tied with through wall ties. The standard statical proof for the Climbing Scaffold has been prepared and is available. A separate design calculation for special cases has to be worked out when necessary. The proof of the anchoring (suspension) of the climbing brackets can be taken from the relevant documents. Using the CS 240 L System, the German Standards DIN 4421 (8/82) for falsework, DIN 4420, Part 1 (/90) for working and safety scaffolds, and the accident prevention regulations of the BBG must be adhered to. The following instructions for erection and use comprise detailed information on handling and use of the listed and depicted products used in accordance with the prescriptions. The function-related instructions stated in this assembly manual have to be strictly obeyed to. Deviations from this always require a separate statical proof. All nationally valid prescriptions and regulations regarding safety and health on construction sites have to be adhered to. Safety regulations of the professional association and/or other relevant authorities have to be taken notice of, too. Use only original parts supplied by HÜNNEBECK which are in an immaculate and undamaged condition. Therefore, all components have first to be checked visually to make sure that they are from the HÜNNEBECK company and are not damaged before they will be installed. Damaged parts have to be sorted out and replaced by new ones. For repairs, only original parts of the HÜNNEBECK GMBH have to be used as spare or replacement parts. Combined use of our temporary edge protection system with components from other manufacturers is a source of risk and requires a careful check and evaluation. The technical details stated within the scope of these Instructions for Assembly and Use are intended to enable the user and/or erector to apply the system

30 6.0 Anchoring Installing the anchor for next lift (lead cone) Without drilling through the shuttering skin. (using the nailable disk) 1. The nailable disk has to be nailed to the shuttering skin (plywood). 2. The tie cone with the tie rod and counter plate can now be screwed on the threaded bolt of the nailable disk. The formwork element is loosened from the wall when dismantling. The nailable disk remains to be fixed to the tie cone and must be unscrewed with a hexagon socket screw key (w.a.f. mm). Fasten bracket bearing roll with hexagon fit bolt M 27. Drilling a through hole in the plywood. (using the fit bolt M 27 x 90) The shuttering skin must be provided with a through drill hole (28 mm dia.) at the correct level. The fit bolt M 27 is to be unscrewed and removed and the formwork loosened from the wall when striking the wall element. Then the lead cone (for next lift) is to be screwed to the plywood by using the fit bolt M 27 from behind the shuttering skin. A small plywood pad with a drill hole (28 mm dia.) is needed between the rear side of the plywood and the head of the screw as an adjustment piece (by site). After this, the bracket bearing roll is fastened with the heaxagon fit bolt M 27. Recovering the tie cone. After unscrewing the hexagon fit bolt, the tie cone can be turned and removed from the concrete wall by means of a hexagon socket screw key (w.a.f. 27).
