  • the pivoting action is effected by pin in socket connections 23, 24. It will be observed that the axis of pivot for ail pin in socket connections 19, 20, 23, 24 is at right angles to horizontal axis 14 and this relationship remains throughout all pivot angles of the grab 10 (refer to Fig. 2).
  • Pads 21, 22 present a flat surface 25, 26 respectively adapted to be urged against a peripheral surface of garbage bin 11.
  • the flat surfaces 25, 26 are inclined so as to face generally towards the centre of the area generally defined by the cradle arms 15, 16 and fingers 17, 18.
  • the cradle 12 is pivotally connected to a reference surface 27 by axle 28 so as to be pivotable about horizontal axis 14 with respect to the reference surface 27.
  • the longitudinal axis of the axle 28 is aligned with horizontal axis 14 which, in turn, is generally aligned with the longitudinal axis of base portion 13 of cradle 12.
  • the cradle 12 can be urged to pivot about longitudinal axis 14 by the action of linear actuator 29 acting upon a free end of link arm 30.
  • Link arm 30 is affixed to axle 28.
  • Linear actuator 29 is affixed to reference surface 27.
  • Reference surface 27 can be, for example, a side portion of a refuse collection vehicle or the end of a collection arm which, in turn, is connected to the refuse collection vehicle.
  • the flat surfaces 25, 26 of the pads 21, 22 are constructed from neoprene so as to reduce surface damage to bin 11 and also minimise the risk of slippage of the bin 11 when retained within and by grab 10.
  • Other interior surfaces which will come into contact with the exterior surface of bin 11 can also be constituted from neoprene for the same reasons.
  • Figs. 3 and 4 illustrate the manner in which bins of various cross sectional shape and orientation can be accommodated by grab 10.
  • Finger linear actuators 31, 32 act upon fingers 17, 18 respectively about pin in socket connections 19, 20 with reference to cradle arms 15, 16 whereby the angle subtended between an inside surface of arms 15, 16 and an inside surface of fingers 17, 18 can be decreased as the linear actuator 31, 32 respectively extends.
  • Fig. 5 provides a hydraulic circuit suitable for operation of linear actuators 29, 31, 32 when these actuators are implemented as hydraulic rams.
  • the grab 10 can be operated as follows:- The grab 10 is usually stored in the vertical position, thereby reducing the protruded length from the reference surface 27. In this position, the grab fingers 17, 38 are in the open position.
  • the operator By releasing the release button 36, the operator can stop and hold the position of the components at any time. Therefore, he can normally depress the grab button until the cradle had reached the horizontal position, then release it until he has extended the loader next to the bin 11.
  • embodiments are:- reduced protrusion from the side of the vehicle;
  • Fig. 6 illustrates a grab 40 according to a second embodiment of the invention pivotally attached to an arm assembly 41 whereby the grab 40 can be raised and caused to pivot to a substantially vertical alignment for the purposes of dumping the contents of a bin 42 (retained by the grab 40) into a mobile refuse collector 43 to which arm assembly 41 is attached.
  • the grab 40 according to the second embodiment is shown in more detail in Figs. 7, 8 and 9 and will be seen from these drawings to comprise a cradle 44 comprising a reference or base portion 45 from both ends of which extend outwardly, in parallel, a first arm 46 and a second arm 47.
  • first grab finger 49 Pivotally attached to first arm 46 by pivot 48 is first grab finger 49. Pivotally attached to second arm 47 so as to pivot about pivot 50 is second grab finger 51. Fingers 49, 51 are caused to move and pivot with respect to pivots 48, 50 respectively by a finger actuation assembly 52 attached to respective first arm 46 and second arm 47.
  • Finger actuation assembly 52 comprises a linear actuator 53 whose actuation rod 54 is pivotally connected to a grab finger support arm 55 by means of articulated
  • Finger actuation assembly 52 further includes a collar 57 which includes a guide 58 offset from respective pivots
  • Articulated connection 56 is adapted not to pass through guide 58.
  • linear actuator 53 moves from its retracted position shown in Fig. 7 to a first extended position shown in Fig. 8 at which position articulated connection 56 abuts collar 57 and will not pass through guide 58.
  • actuation rod 54 urged by linear actuator 53 has caused the grab finger support arm 55 to move through guide 58 so that grab fingers 49, 51 adopt an extended position relative to arms 46, 47 and reference/base portion 45 of cradle 44.
  • Linear actuator 53 continues to urge actuation rod 54 away from linear actuator 53. This urging is transferred to the abutment of articulated connection 56 with collar 57 causing collar 57 to pivot about pivots 48, 50 respectively. As illustrated in Fig. 9 this action causes articulated connection 56 to break towards an acute angle.
  • the brackets 59, 60 allow grab fingers 49, 51 to realign themselves so as to maximise their contact area with bin 42.
  • Bin 42 is now retained within cradle 44 of grab 40 and can be lifted in the manner illustrated, in sequence in Figs. 11, 12, 13 and 14 by arm assembly 41.
  • Arm assembly 41 is freely pivotally connected to end 64 of arm assembly 41 by pivot support 63 so as to pivotable from a substantially horizontal position (as illustrated in Fig. 11) to a substantially vertical position (as illustrated in Figs. 13 and 14) about pivot 65.
  • grab 40 is stored in a substantially horizontal position beneath mobile refuse collector 43 as illustrated in Fig. 10.
  • Fig. 10 also illustrates the manner of movement of end
  • the grab assembly can be stored in a limited space beneath a vehicle and/or that the parallel alignment of the first arm 46 and second arm 47 allow bins 42 placed closely side by side to be selected individually for attention by the grab 40.
  • the grab has particular, but not exclusive, application for use in conjunction with arm assemblies connected to mobile refuse collectors whereby bins or containers
  • containing refuse material can be selected from the kerb side, retained by the grab and caused to have their contents dumped into the mobile refuse collector.

Abstract

Mécanisme de préhension (40) permettant de saisir un conteneur ou une benne (42). Le mécanisme (10, 40) comporte un berceau (12, 44) comprenant une partie inférieure ou de référence (13, 45), à partir de laquelle s'étendent un premier (15, 46) et un deuxième (16, 47) bras, à partir desquels s'étendent, à leur tour, des doigts de préhension (17, 18) ou (49, 51). Le mécanisme est conçu pour s'aligner selon l'une des deux positions possibles du fait que le berceau (12, 44) se déplace à partir d'un alignement essentiellement horizontal jusqu'à un alignement essentiellement vertical par rapport à l'axe horizontal selon lequel le berceau est monté pour pivoter.
