constant support given to contractors and help provided with new tasks for current projects. For all construction projects, PERI can provide everything from one source. Eelised • Maximum reduction in the number of special parts Only a few different components are used for the whole system: - 3 core components (Climbing Rail RCS, Steel Waler Universal SRU, Heavy-Duty Spindle SLS) - accessories such as scaffold tubes and couplings For the complete construction kit, there are only a few type connections with particular advantages: - few different connecting parts such as pins and cotter pins - standardized loads according to type of connection - simple and easy on-site assembly • Perfect adjustment to project requirements - SRU steel walers (16 lengths from 72 cm up to 6 m) - RCS climbing rails (5 lengths from 2.5 m up to 10 m)

Each valve or pump is actuated by a cam follower, which rises or falls as the cam rotates beneath it. The camshaft is built together of a number of camshaft sections. The sections are assembled by means of flange couplings, which are joined together with bolts and nuts. Furthermore, the camshaft sections have, for each cylinder, one cam for operation of the fuel pump, one for the exhaust valve, and one for the indicator drive. The cam for the indicator drive is in two parts, which are assembled by means of two bolts, whereas the coupling flanges and the fuel pump and exhaust valve cams are shrunk onto the shaft by heating. The camshaft is carried in underslung bearings, which are fitted in the housing
