Vaino J. Holopainen, East Sullivan, New Hampshire (USA) Material transport device

This invention is concerned with a material handling device, however, it is concerned in particular with a device for industrial transport processes and for excavation, with an additional unit assigned as a working device to an articulated vehicle is ο

As for the manufacture of equipment for material handling concerns, for example, of equipment for the Erdau.shub or for industrial transport, so has Over the years, the use of hydraulically operated auxiliary units as work equipment has always increased more reinforced. Unfortunately, from that moment on, "attached to the ancillary equipment to the back of an ordinary Agricultural tractors have been put on, developing the devices in the wrong direction accomplished by the fact that today's devices resemble the devices of the older version and differ from them differentiate between older devices only in that the tractor, the tractor and the accessories have become larger. The function of the devices has not changed, so that the application of the various additional equipment used as tools a variety different types of vehicle has made necessary and makes it necessary to which the additional equipment must be mounted. Now the device is more likely to face the problem, not just a big one Variety of vehicle types and additional units that are assigned to these vehicle types as additional devices, to have to manufacture. He also stands on top of that

still, facing a spare parts problem, because to meet customer demands To be able to satisfy the manufacturer, but also the dealer, a very large number of spare parts need to keep in stock. In addition, because today's material handling equipment is based on a simple Extrapolation of the earlier primitive constructions are constructed, the puncture remained the same, even if today's material transport devices are in the Are able, greetings? Moving loads. The way to transport material has changed in all of them Not changed in years. Additional units as additional devices, for example, "hydraulic Ausleger-Ladeschaufoln and Eint.iuchstangcn-Ladeschauf are in theirs Use restricted to vehicles of the currently available construction in an extreme Woise, so can Then dig vertical trenches only with difficulty, we.nn the FVihrzeug steep on a sloping slope got to. In addition, it is difficult to produce smooth sides on an embankment if there are the vehicle is in a fixed and stationary position because the angle or the angular position is dex * cutting edge changed when the additional device is rotated or panned. Furthermore, preliminary searches, additional devices of various designs to use with dom same equipment, essentially leading to a significant mismatch to this can lead to »that the device is not very useful, because of its mounting on the wrong vehicle. One of the problems or one of the adverse effects for example with the Einsoitz one hydraulic

The fact that it is impossible to dig a trench close in a wall or close to a building, because the mass of the vehicle prevents the center line of the detaching combination or the immersion rod combination from coming close to each other on the wall, so that, in other words, it will be necessary to dig this trench a considerable distance outside the wall. ? Λι create tests, these problems or disadvantages from a so-called on to rite "SideShif (-Device" or Seitenverschiebungsvorrlchturig from the world, not as vü have therefore proved ig 1 J · satisfactory because Diesi; Since onvorschiobungsvorrichtungen not designed for heavy lusts are, because these side-shifting devices are complicated and in operation they are difficult, if they are exposed to the dirt and dust during the practical excavation process Conventional and hydraulically powered loader buckets are somewhat limited because neither the angular position of the bucket can be changed nor the effective length of the shaft to which the bucket is attached can be changed in any way. It is impossible using the conventional hydraulic loader bucket, for example To "level slopes" because the angular position of the Blade cutting edge with swinging around the vertical axis at the rear end of the vehicle changed.

Implementation of leveling and smoothing work the cutting edge of the bucket 26 can be aligned parallel to the surface of the embankment.

Fig. K now shows how the connecting element 13 and the telescopically extendable boom 2k can be used to achieve an extremely great depth when excavating earth, but also to achieve ρinor extreme piercing work during the completion of the end faces of a hole. The first part '} & dos connecting element 13 is gonoigt about its axis, in such a way that the swaying point for the boom is displaced forwards

is, on the other hand, the telescopically extendable logerarm is then extended by extending it. In many situations, the telescopic movement of the Aus Loger can be used to guide you To achieve a certain scratching effect, bring the bucket over a certain line

FIG. 5 shows how the device can be used to dig a trench that is led very close to a wall k2 or a building. The vehicle 11 is set up so that its rear part Ik and its front part Part l6 form a large angle, with the wheels of the vehicle being very close to the wall or wall k2 ο Then the additional unit or the implement 12 is pivoted by means of the third part kl belonging to the connecting element 13 into a position in which the boom 2k is aligned parallel to the wall in which the loading shovel continues

is aligned with its cutting edge in the right leg to the wall and is very close to this wall. In this state it is possible to dig a trench parallel to the wall surface. The excavated earth can be loaded into a truck that is parked outside the vehicle and thus also outside the wall. The VJ. hl pivoted about the pivot point of the third part, the pivoting or tipping of \ us1oger and plunger rod is carried out in the usual manner. If the two vehicle parts are swiveled out in opposite directions, it is possible from this position to dig a trench in the form of a wide strip.

May have been, Fig. 6, wio Oine loading shovel mounted k3 ^ i the vehicle 11, and through the intermediary of a connecting element between the two parts, which then work as Matorialtransport device. The stabilizer Jk and the hydraulic linear drive 35 are removed. In this embodiment, a loading shovel is hj pivotally connected to the ends of the planing HUSSEREN k 5 connected with the if ei are in turn with their other ends pivotally ¹ en part of a base structure in k9 · connection. A lever k6 is connected at one end to the upper part of the loading shovel Hh via a connecting lever kj , whereas the other end of the above-mentioned lever 46 is connected by means of a hydraulic linear drive k8 to a projection k9 which is guided upward from the platform. Another hydraulic linear drive

^. _Λ ·. ΠΗ066

connects the approach 49 with the middle part of the lever arm k6. In each case two sets of these last-mentioned drives, levers and rocker arms are attached to the two opposite sides of the center line of the vehicle.

Fig. 7 shows a material transport device which is mounted in the form of an additional unit, ie as a jib crane, on the vehicle and the connecting element 13. A jib 53 is pivotable with a projection 13 from upwards. The hydraulic linear drive 55 connects the extension 5 ^ with dom extension * ¹ 53, it can change the angular position of the extension in this way , which are driven and held by (not shown) Linoarantriobon.
