Abstract

1303487 Controlling garage lifting platforms CECCATO & C SpA 5 June 1970 [21 Oct 1969] 27184/70 Heading B8H [Also in Division F2] A garage lifting platform actuated by a jack 1 has four supports 3 (only one being shown). Fluid pressure is supplied by a pump 7 driven by an electric motor controlled by a circuit illustrated in Fig. 2 (not shown). Control valve 13 and distributer valve 16 have a common operating lever 20. The control valve 13 has two positions: "consent" and "refusal"; the distributer valve has three positions: "ascent" (s); "descent" (d) and "mechanical locking " (p). The valves 13, 16 are so interconnected that one of the operations s, d or p can be pre-selected by the valve 16 only when the control valve 13 is set to " refusal " (i.e. no operation allowed) whereupon moving the control valve 13 to "consent" initiates the operation.
