  • Each of the rods 38 is connected to the arm 32, 34 in which it is received so that extension and retraction of the rod, by the application of fluid pressure to one side or the other of the piston in the cylinder 36, will extend and retract the arms 32, 34.
  • Each arm 32, 34 terminates in a collar 44 in which a jack cylinder 46 is secured.
  • the cylinder 46 which is vertically oriented, has a piston (not shown) with a rod 48 extending downwardly therefrom.
  • a pad 50 is secured to the rod 48 for engagement with the ground when the outrigger box is mounted on the crane, and the rods 48 extended to their normal supporting positions. 2 depicts equally as well either the rear outrigger support or the central outrigger support.
  • the truck carrier 12 has eight pairs of lugs 56 depending therefrom. Four pairs of lugsdepend from the rear of the carrier and support one outrigger support 28 at an operating position P1; four pairs of lugs depend from the central region of the carrier and support another outrigger support 28 at an operating positionPZ. Insofar as the details of the mounting construction, and the details of the outrigger support 28, are concerned, FIG. DEPICTS EQUALLY AS WELL EITHER THE REAR OUTRIGGER SUPPORT OR THE CENTRAL OUTRIGGER SUPPORT.
  • the center of the lower surface 60 of the truck carrier is indicated by the longitudinal axis A (extending from front to rear of the vehicle).
  • One pair of lugs depends from the surface 60 at each corner of an imaginary rectangle R lying in surface 60.
  • the lugs, each of which has a circular opening 61 therethrough, lie in planes perpendicular to axis A.
  • the rectangle R lies square, and centered,with respect to axis A as indicated in FIG. 2.
  • the outrigger box 30 has, at each corner, an upstanding ear, or lug 62, which, when the outrigger box is moved into mounting position on the crane, will each extend (in planes perpendicular to axis A) between one of the pairs of lugs 56 at the corners of the rectangle R.
  • Each lug 62 has a circular opening 64 therethrough.
  • Each actuator 70 is each connected between two of the pairs of lugs to extend parallel to axis A.
  • Each actuator 70 has a flange 72 at each end which is connected to the inner lug 56 of the pair.
  • each actuator extends from the rear lug of the front pair of lugs, to the front lug of the rear pairs of lugs which lie directly behind the front pair.
  • each actuator 70 has a housing 74 with a cylindrical chamber 76 therein.
  • a snap ring 78 centrally mounted in the wall of chamber 76 divides the chamber into two halves, each half receiving a piston 80 therein.
  • Each piston 80 has an internal chamber 82 which receives a second piston 84.
  • Piston 84 has a piston rod 86 connected thereto which extends through piston 80.
  • a cylindrical plunger, or latch, 88 is secured on rod 86 outside the piston 80.
  • each actuator 70 securely fastens one end of the outrigger box to the carrier. and the two actuators together securely fasten the outrigger box for use as a truck carrier support.
  • each outrigger box has two cylinders 36 for the extension of the arms, or tubes, 32, 34.
  • the cylinder lines connected to each end of the cylinder 36 are connected to quick-disconnect plugs 100, I02 mounted on the truck (FIG. 5).
  • the operation of the actuators 70 is effected by connecting lines 92 and 96 to disconnect plugs 100, 102 respectively as shown in FIG. 5.
  • the actuator lines 92, 96 are disconnected from the plugs 100, '102 and the lines for the outrigger cylinders 36 are then connected to these plugs.
  • a circuit for supplying fluid under pressure selectively to the disconnect plugs 100, 102 is shown in FIG. 5.
  • a pump 104 driven by motor 106, pumps fluid from reservoir 108 into line 110 under pressure.
  • Line 110 contains a pressure regulating valve 112 which bleeds fluid through return line 114 to reservoir 108 as necessary to maintain a predetermined pressure in line 110.
