SIDE-LOADING SELF-PROPELLED MATERIAL TRANSPORTING DEVICE This application is a continuation-in-part of my prior copending application Ser. No. 725,014, filed Apr. 29, 1968, now abandoned.

SUMMARY The present invention relates to a side-loading material transporting device having laterally extending jointed arms hydraulically actuated, with winch means in the heads of the arms,and stabilizing means extending laterally from said device, said arms being movable into load lifting and depositing position to load material on the vehicle or on raisedstacks, and the like, adjacent the vehicle, or into other vehicles on a lower plane such as barges.

An object of the present invention is to provide an improved side-loading material transporting device which is capable of lifting substantial elongated loads and of carrying such loads through a narrow space.

Another object is to provide an improved side-loading material handling device having a maximum bed area for carrying materials.

A further object is to provide an improved side-loading material handling device which is simple to operate and provides a maximum amount of safety in handling loads.

BRIEF DESCRIPTION OF THE DRAWINGS These and other objects of the present invention are hereinafter set forth and explained with reference to the drawings wherein:

FIG. 1 is a side view, in perspective, of the device with the arms in retracted position.

FIG. 2 is a rear view of the device, showing the arms in another position, and illustrating the movement of the arms in dotted lines.

FIG. 4 is an enlarged front view of one form of arm head, showing the winches employed in dotted line.

FIG. 5 is a fragmentary view of a fork mounted on the end of the arms.

FIG. 6 is a side elevation view of a modified form of device showing the engine location below the loading bed.

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.

DESCRIPTION OF THE PREFERRED EMBODIMENTS In the drawings, the numeral 1 designates a flat bed vehicle body having thecab 2 housing the motor and controls (not shown) and having the fixed boom supports 3, 3. A pair ofmain boom members 4, 4 are pivotally mounted on thesupports 3, 3 and thegantry members 5, 5 are pivotally mounted on the extended ends of saidmembers 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 eachsupport member 3, 3, and the hydraulic ram 8 mounted on the vehicle bed between theboom 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 theboom members 4, 4, rearwardly of thefulcrum point 10, 10 of themain boom members 4, 4 in thesupports 3, 3.

Hydraulic rams ll, 11 are mounted on the inside walls of theboom members 4, 4 and the extended ends of the pistons of said rams 11, 11 are pivotally anchored to thegantry members 5, 5.

The extended ends of thegantry 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 thesupports 3, 3.

In operation, 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 theusual line 15 andhook 16 being employed in the usual manner, and said winches 12, 12 being operable independently or together. With the booms movable as shown in FIG. 2, 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.

In the form shown in FIG. 5, afork 17 is attached to thearm 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 thevehicle 19.

A modified form of side-loading truck is shown in FIGS. 6 through 10. Such truck has abed 20 suitably supported on wheels with an engine mounted in the housing 21 centrally beneath thebed 20, acab 22 and loading means mounted to one side of thebed 20.

As in the form of device previously described, the lifting means includes arotary table support 23, with jointedarms 24 tied together by thetraces 25 pivotally mounted onsupport 23 and thewinches 26 in the heads onarms 24. Any suitable load engaging means may be used and in the modified form shownmagnets 27 are supported on thecables 28 from the winches. As shown in FIG. 6, thebed 20 has the stabilizingrams 29 on the side of the bed away fromcab 22 and support 23 similar to thestabilizers 14 previously described.

Thehydraulic rams 30 engage the transverse supportingshafts 31 to control the pivoting of themain boom members 32 with respect to thesupport 23. Thehydraulic rams 33 control the pivoting of thegantry members 34 with respect to themain boom members 32.

Thearms 24 are similar to thearms 4, 5 except that both themain boom members 32 and thegantry 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.

The telescoping structure of the arm members is best shown in FIGS. 9 and 10. Agantry member 34 is shown composed ofend members 35 and 36 with telescopingstructural means 37 extending between the end members and theram 38 extending between theend members 35 and 36 and through thestructural means 37.

The telescopingstructural means 37 includes theouter box member 39, theinner channel 40 and the means slidably supporting thechannel 40 within thebox 39. Such support means includes therollers 41 which engage the corners ofchannel 40 and therollers 42 which engage the ends of the legs of thechannel 40. Each of therollers 41 and 42 are rotatively mounted on pins which are supported by portions of thebox 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.

Thecab 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. Also, sincesupport 23 is a rotary table type of support the pivoting ofcab 22 is especially desirable to give the operator a clear view of theam 24 particularly when they have been rotated to a position other than extending across thebed 20.

While the foregoing is considered the preferred embodiments of the invention, they are by way of illustration only, the broad principle of the invention being defined by the appended claims.
