Definitions

  • the invention relates to the field of dual controls for motor-vehicle-mounted hydraulic cranes, and more exactly, to a duplicate control station of the type which comprises a set of handles that operate a horizontally disposed directional control valve by way of respective rods.
  • the control valve handles and the duplicate handles are located at opposite sides of the motor vehicle.
  • Conventional dual control vehicle-mounted hydraulic cranes are located between cab and body, and can be worked from either side of the vehicle, by way of a directional control valve of the type provided with a system of levers and manually operated horizontal handles.
  • a duplicate set of handles is provided at the side opposite that to which the control valve is fitted.
  • the dual controls are linked by rigid tie-rods crossed one over the other such that the positions of the control valve and the duplicate handles remain the same.
  • each handle of the duplicate set of controls is connected to a respective rod by way of a linkage element, and each such linkage element is coaxial with and rotatable independently of the remaining elements.
  • One advantage of the invention consists in the extreme simplicity of the duplicate control station, a feature which both ensures marked economy and guarantees practical, faultless operation of the hydraulic crane's dual controls.
  • Another advantage is that of the facility of keeping control rods substantially parallel with each other, which limits the number of likely breakdown hazards inasmuch as there is no need whatever for complex linkage systems of the type required in conventional crossed rod connections.
  • a hydraulic crane 10 of the type in question is usually bolted to the platform 9 of a motor vehicle, or truck, between the body 7 and the cab 8.
  • the crane 10 is manoeuvred manually by the operator, who works a hydraulic directional control valve 2 located at one side of the vehicle.
  • 4 denotes a duplicate control station, that is, a duplicate set of controls located at the opposite side of the vehicle, from which the control valve 2 is operated by way of a set of rods 3 running across the vehicle.
  • the duplicate control station 4 consists in a set of linkage elements 5 (the drawings show five, denoted 51, 52, 53, 54 & 55), one to each of the duplicate handles 1 (denoted 11, 12, 13, 14 and 15 respectively); such elements are coaxial with each other, and freely rotatable in relation to one another.
  • the innermost element 55 is supported at each end by a U-shaped component 6 issuing from the main frame of the crane 10, and capable of no other movement than rotation about its own axis.
  • the ends of the element 55 adjacent to the uprights of the U-shaped component 6 are integral, on the one hand, with the end of a first duplicate control handle 15, and on the other, with a crank 155 to which the respective rod 35 is attached.
  • the linkage element denoted 51 is tubular in shape, and ensheaths the stretch of the element denoted 55 between the first handle 15 and the crank 155.
  • This element 51 is freely rotatable in relation to that denoted 55, and its two ends are integral, on the one hand, with the end of a second duplicate handle 11 positioned adjacent to the crank denoted 155, and on the other, with a crank 151 to which the relative rod 31 is attached.
  • a linkage element denoted 54 ensheaths the stretch of the element denoted 51 between its control handle 11 and crank 151, and is integral with a third duplicate control handle 14 at the one end, adjacent to the crank denoted 151, and at the other, with a crank 154 to which the relative rod 34 is attached.
  • This element 54 is ensheathed by the element denoted 52, and the latter ensheathed in its turn by a further element 53.
