Abstract
Disclosed is a skid device for a vehicle to facilitate use of the vehicle on soft or boggy ground. The device is operable between a retracted position in which the ground facing surface is spaced apart from the ground, to enable the vehicle to be driven in normal conditions, and a deployed position in which the device is lowered, to support some of the weight of the vehicle and prevent the vehicle's wheels or tracks from sinking or digging into the soft ground.
Description
I
Title: Tracked or Wheeled Vehicle with Skid The present invention relates to a tracked or wheeled vehicle with a skid.
Tracked vehicles such as excavators are often used on soft ground. In wet conditions, the tracks can sink deep into the ground making it difficult to drive the vehicle forward or backwards or, in extreme cases, rendering the vehicle immobile. The same can apply to wheeled vehicles.
The invention seeks to provide a solution to this problem.
According to the present invention there is provided a vehicle comprising: a) a vehicle body, b) spaced tracks and/or wheels projecting below the vehicle body to engage the ground, and c) at least one skid between the tracks and/or wheels, the or each skid being moveable from a first upper position above the ground to a second lower position to engage the ground, in use, the or each skid in the second lower position reducing the ground pressure on the tracks and/or wheels and skidding along the ground as the tracks and/or wheels drive the vehicle body.
The or each skid may be moved from the first to the second position by a hydraulic or mechanical device. The or each skid may be connected to the vehicle body by at least one telescopic shaft allowing the skid to be moved from the first to the second position and vice versa.
The or each skid may have turned up ends to ride over undulations in the ground surface.
An embodiment of the invention will now be described with reference to the accompanying drawings in which: Figure 1 shows a rear view of a tracked excavator with a skid in a first upper position, Figure 2 shows a rear view of a tracked excavator with a skid in a second lower position, and Figure 3 shows side view of the skid.
Referring to Figures 1 and 2 there is shown a vehicle in the form of a tracked excavator 1.
Excavator 1 has a vehicle body 2 with a chassis 3. A pair of spaced tracks 4A,4J3 project below the vehicle body 2 to engage the ground.
A skid 10 is provided between the tracks. Skid 10 is moveable from a first upper position above the ground (see Figure 1) to a second lower position to engage the ground (see Figure 2).
In use, skid 10 in the second lower position reduces the ground pressure on the tracks preventing the tracks from sinking into the ground, and skid 10 slides along the ground as the tracks drive the vehicle body 2.
Referring now to Figure 3, skid 10 has mined-up ends 11A,11B to ride over undulations in the ground surface. Skid 10 is connected to chassis 3 by four telescopic shafts 12A,12B,12C12D (12C not shown) which may be mechanically or hydraulically operated. Shaftsl2A,12B,12C12D allow the skid 10 to move from the first to the second position and vice versa. Instead of four shafts as shown, more or less shafts may be provided.
Skid 10 could be built into new vehicles or retro-fitted to existing vehicles.
The invention may take a form different to that specifically described above. For example more than one skid may be provided. Also the vehicle could be a wheeled vehicle.
Further modifications will be apparent to those skilled in the art without departing from the scope of the present invention.
