Description

Truck Bank - Banke för lastfordon Technical field of the invention

The present invention relates to a bank for a truck, preferably a forwarder or a similar vehicle, which includes a handle mounted on the vehicle and a load support attached to the outer end of the arm.

Technology background

The maximum width of the forwarder is the width between the supports, which makes it more difficult to move forward without the load. Light timber may require a large load area and also width to provide full load, but for heavy timber, full width may be unnecessary, and mobility will be improved if the width can be reduced as needed.

Objective of the Invention

It is an object of the invention to enable the loading area and the width of the forwarder to be adjusted.

Detailed Description of the Preferred Embodiment of the Invention

CVJ

Figure 1 shows a conventional frame-controlled forwarder, comprising a load section having three bank pairs and load supports 11, 12, 13 and a crane 14. The front portion of the load section has an end 15 which protects the cab.

Fig. 2 shows the load section of a forwarder. The load portion is not consistent with the load portion of the forwarder shown in Figure 1 and has two pair of racks 16, 17 and 18, 19 containing four similar load supports 20-23, all of which are shown in two different positions in this figure. Banks are attached pa-5 to the middle beam 24.

Figure 3 shows a bank 17 in which the load support is in one of its alternative positions. The bank 17 consists of a shank 25 and a load support consisting of an inner part 26, 27 and an outer part 28. The inner part consists of two connecting parts or shank 26, 27 pivotally mounted to pivot about axes I and II. The outer portion 10 of the load support is pivotally mounted on two connecting portions 26, 27 to pivot about two axes III and IV. The four axes form a parallelogram so that the outer part of the load support always becomes parallel when the inner part 26, 27 of the load support is rotated about the axes I and II. The four axles are parallel to the longitudinal axis of the vehicle. Fig. 4 shows the inner part 26, 27 of the load support, which is swung open in its horizontal end position, where the connecting part 26 rests against the stops 30 on the arm 25. When the load support is raised in Fig. 3, it can be locked into the holes 31 in the connecting member 26 and the corresponding holes 33 in the arm 25 by the plugs 32. The raised position is defined such that the connecting member 26 rests on the shaft pin 34 34 forming the shaft II.

Figures 2-5 show the top 28 of the load support in a tubular form. It can be fitted with extensions as shown in Figure 1.

Figure 5 illustrates a longitudinal section of the bank 17, with the load support 26, 27, 28 shown in both positions. Figure 6 is a cross-sectional view of the connecting members 25 26, 27 and a space is formed therebetween for the gas spring 35, one end of which is secured to the holder 36 secured to the connecting member 26 and the other end to the connecting member 37 pivotally attached. one when the inner part 26, 27 of the load support is moved from one end position to the other, whereby the gas spring 35 bistably forces the inner part of the load support x 30 to one of its end positions when the inner part 26, 27 is centered by external force. To provide external power, the crane mattress crane 14 is used, which is a viable solution since no "fine motor
