Definitions

  • FIGURE 1 represents in front elevation counterbalance means in accordance with the invention
  • FIGURES 2 and 3 represent respectively in front and ice side elevation counterbalance means in accordance with the invention.
  • a bracket-shaped platform 8 is fitted with guiding and supporting rollers 9 which run in slotted or grooved ways in the arm 3.
  • a pulley 10 is rotatably mounted in the arm 3 at its upper end.
  • a cable 11 secured by one end to the bracket platform 8 runs over the pulley 10 and at its other end is attached at 12 to a fixed part 2 of the vehicle.
  • a heavy mass 13 is mounted on and secured to the platform 8 (but may be interchangeable with other blocks of different sizes and weights).
  • a weight 29 extending transversely of the upright limbs of the frame 24 is mounted on hydraulic rams 30 and slidable on the outer sides of the limbs of the frame.
  • the weight 29 is lifted towards the upper end of the frame 24, and if this frame is in (or is moved to) an extended position the weight applies a substantial torque to the vehicle to counterbalance a torque derived from a crane or like lifting means extending from the opposite side of the vehicle and lifting a load, e.g. a pipe.
  • Crane-like lifting and lowering means provided with a counter-balance device comprising a boom mounted for pivotal movement between a substantially vertical position, and a position inclined to the vertical, a weight mounted on, and movable along said boom, a first hydraulic means adapted, when actuated, to swing said boom about its pivot irrespective of the position of said weight on said boom, and a second hydraulic means adapted to move said weight along said boom irrespective of the in.- clination of said boom.
  • Crane-like lifting means with a counterbalance device wherein the boom is an inverted U-shaped frame mounted on a pivot adjacent to the lower ends of its legs, and the weight is carried by a support extending transversely of the legs of said frame, and movable longitudinally along said legs.
  • a vehicle comprising a weight-lifting crane on one side of said vehicle, and on the other side of said vehicle a counterbalance device comprising a frame pivoted at its lower end of said vehicle, and movable about its pivot between substantially vertical, and outwardly inclined, positions, a weight mounted on, and movable longitudinally of, said frame, first hydraulic means connected between said vehicle and said frame, adapted when actuated to swing said frame about its pivot, and second hydraulic means connected between said weight and said frame, adapted when actuated to displace said weight along said frame.
