  • FIG. 7 is an elevation view of one of the modified arms having both extensible gantry and boom.
  • FIG. 8 is a plan view illustrating the pickup of a load and the movement of the cab so that the operator can face forward during movement of the device and the load during lifting operations.
  • FIG. 9 is a side view of the extensible gantry.
  • FIG. 10 is a sectional view of the roller support for movement of the telescoping sections of the gantry taken along line 10-10 in FIG. 9.
  • the numeral 1 designates a flat bed vehicle body having the cab 2 housing the motor and controls (not shown) and having the fixed boom supports 3, 3.
  • a pair of main boom members 4, 4 are pivotally mounted on the supports 3, 3 and the gantry members 5, 5 are pivotally mounted on the extended ends of said members 4, 4, forming the gantry boom.
  • Supporting members 6, 6 maintain the main boom members in horizontal alignment, and hydraulic rams as 7, 7 adjacent each support member 3, 3, and the hydraulic ram 8 mounted on the vehicle bed between the boom members 4, 4, have the extended ends of their ram piston arms mounted on the transverse supporting shaft 9.
  • the shaft 9 is in the ends of the boom members 4, 4, rearwardly of the fulcrum point 10, 10 of the main boom members 4, 4 in the supports 3, 3.
  • Hydraulic rams ll, 11 are mounted on the inside walls of the boom members 4, 4 and the extended ends of the pistons of said rams 11, 11 are pivotally anchored to the gantry members 5, 5.
  • the extended ends of the gantry members 5, 5 form the head of the gantry, having the hydraulically operated winches 12, 12 which actuate the cat heads l3, 13.
  • a pair of hydraulic rams act as stabilizers l4, l4 and are mounted on the vehicle bed 1, on the side opposite the supports 3, 3.
  • the controls in the cab permit the loading arms to be employed in loading pipe, steel beams, lumber and the like from the side, the jointed structure permitting picking up a load from a stack, barge or car, or the like, and placing same on the truck in the desired location, the cat heads, with the usual line 15 and hook 16 being employed in the usual manner, and said winches 12, 12 being operable independently or together.
  • the load may be taken from or deposited on stacks below or above the level of the truck bed, the dual arms providing adequate power as well as control of the load being lifted.
  • a fork 17 is attached to the arm 18, in lieu of the catheads. With the arm being jointed, the load may be lifted from any location and maintained level as it is loaded on the vehicle 19.
  • FIGS. 6 through 10 A modified form of side-loading truck is shown in FIGS. 6 through 10.
  • Such truck has a bed 20 suitably supported on wheels with an engine mounted in the housing 21 centrally beneath the bed 20, a cab 22 and loading means mounted to one side of the bed 20.
  • the lifting means includes a rotary table support 23, with jointed arms 24 tied together by the traces 25 pivotally mounted on support 23 and the winches 26 in the heads on arms 24. Any suitable load engaging means may be used and in the modified form shown magnets 27 are supported on the cables 28 from the winches.
  • the bed 20 has the stabilizing rams 29 on the side of the bed away from cab 22 and support 23 similar to the stabilizers 14 previously described.
  • the hydraulic rams 30 engage the transverse supporting shafts 31 to control the pivoting of the main boom members 32 with respect to the support 23.
  • the hydraulic rams 33 control the pivoting of the gantry members 34 with respect to the main boom members 32.
  • the arms 24 are similar to the arms 4, 5 except that both the main boom members 32 and the gantry members 34 are extensible. By constructing such members of telescoping structural members and means for extending and retracting the structural members, the flexibility of the loading means is substantially extended.
  • Such structure allows loading from and unloading to positions higher, lower and farther from the truck than would be possible with short fixed arms but retains the advantage of minimizing the extention of the arms out from the truck when the arms are in fully retracted posltlon.
  • a gantry member 34 is shown composed of end members 35 and 36 with telescoping structural means 37 extending between the end members and the ram 38 extending between the end members 35 and 36 and through the structural means 37.
  • the telescoping structural means 37 includes the outer box member 39, the inner channel 40 and the means slidably supporting the channel 40 within the box 39.
  • Such support means includes the rollers 41 which engage the corners of channel 40 and the rollers 42 which engage the ends of the legs of the channel 40.
  • Each of the rollers 41 and 42 are rotatively mounted on pins which are supported by portions of the box 39 on both sides of the rollers.
  • FIG. which clearly illustrates the roller support of the telescoping means is a typical section, there being a plurality of such roller stations to assure sufficient strength for supporting all loads imposed thereon.
  • the cab 22 as best shown in FIG. 8 is pivotally mounted on the bed so that the operator can face in the direction of movement when driving the truck and can face the load during loading and unloading of the truck.
  • This pivoting of the cab to allow the operator to see what he is doing without difficulty greatly improves the safety of the improved side-loading truck of the present invention.
  • support 23 is a rotary table type of support the pivoting of cab 22 is especially desirable to give the operator a clear view of the am 24 particularly when they have been rotated to a position other than extending across the bed 20.
