Both rotary and spring balanced arms are made from aluminium extruded profiles. Each pendant version consists of one (two, three, four) rotary arm connected with the swing compact spring balanced arm. The spring arm mechanism allows adjustment of the arm´s loading kapacity 5-28 kg.Rotary joints are equipped with the slip rings allowing the rotation of the arms for 360°. From these poles 3 ones are always designated for transmission of electricity, the remaining ones are for data transmission.When the uninterrupted (optic) cables are used or the unlimited rotation is not needed, the rotary angle is limited by stops.When the uninterrupted (optic) cables are used, the maximum dimension of the terminal plug of the data wire must be defined in accordance with holes in SPR and other installations inside SPR. The inside dimensions to the critical points are: a) pantograph permeability – rectangle 22x12 mm b) spring arm outlet – round cut Ø 22 mmRegarding the smooth wire drawing the maximum recommended terminal plug for one cable is 20 x 10 mm.
SPR 10 ARE MANUFACTURED IN FOUR CEILING VERSIONS (SINGLE, DUO, TRIO, QUATTRO).
