Definitions

  • the present invention relates to a lifting system, for example for roadside emergency means or other.
  • the space occupied by an emergency vehicle may be an impeachment for the positioning of a second emergency vehicle which would allow lifting the overturned vehicle in an optimal manner.
  • the invention particularly makes available a lifting system, comprising: a main frame, a platform pivotally associated with the main frame according to a first rotation axis, a first crane fixed to the platform in eccentric position with respect to the first rotation axis, and a second crane pivotally associated with the platform beside of the first crane and with respect to a second rotation axis, which is parallel and eccentric with respect to the first rotation axis.
  • One aspect of the invention provides for the lifting system to comprise an orientating unit for the first crane, adapted to put the platform into rotation with respect to the first rotation axis, and a second orientating unit for the second crane, adapted to put the second crane into rotation with respect to the second rotation axis, in which the orientating unit for the first crane is independent from the orientating unit for the second crane.
  • the system is particularly flexible and adaptable to any condition of use.
  • a further aspect of the invention provides for the first crane and the second crane to be associated with the platform in positions which are diametrically opposed with respect to the first rotation axis.
  • the distribution of the weights is optimized over the platform, and therefore over the support bearings of the platform, thus allowing a more homogeneous wear of the rotating components.
  • the first crane and the second crane may comprise respectively a first telescopic arm and a second telescopic arm.
  • the cranes have a relatively large radius of action while remaining highly compact.
  • the lifting system may comprise a cart supported by wheels to which the main frame is fixed.
  • the lifting system may be easily transported to bring it where it is required.
  • the first rotation axis may be eccentric with respect to a vertical centreline plane of the cart containing the longitudinal axis of the cart itself.
  • both cranes may be positioned on one side of the cart, thus allowing both to align them to the longitudinal axis of the cart and to take advantage of the maximum radius of action available to both cranes.
  • the lifting system to comprise a motor provided with wheels and associated with the main frame, in which the platform is interposed in a plan view between the motor and the cart.
  • a lifting system comprising a main frame 2 and a cart 3, which is supported by at least one pair of wheels 31 and is fixed to the main frame 2.

  • the system 1 may comprise levelling means adapted to stabilise and/or tilt the main frame 2 with respect to the ground on which the system is resting.
  • the frame may be possible to tilt the frame so that when the system is in use, the first rotation axis Z1 is substantially vertical.
  • first rotation axis Z1 is eccentric with respect to a vertical centreline plane of the cart 3 containing the longitudinal axis of the cart itself.
  • first rotation axis Z1 is positioned between said vertical centreline plane of the cart 3 and a longitudinal side of the cart itself.
  • the platform 5 has a volume in transverse direction, i.e. perpendicular to the longitudinal axis of the cart 3, which is smaller than the volume in transverse direction of the cart 3.
  • the volume in transverse direction of the platform 5 is substantially equal to 0.7 and 0.9 times the volume in transverse direction of the cart 3, preferably 0.8 times the volume in transverse direction of the cart 3.
  • the platform 5 is disc-shaped and the rotation axis Z1 passes through the centre of such disc.
