Abstract

Plow apparatus for work vehicles, particularly of the type which travel on rails, including at least one plow plate pivotally mounted on a respective end of the vehicle in a manner such that the plow plate can be pivoted through an angle of about 180.degree. between a front plowing position in the track of the vehicle and a slide plowing position on the side of the vehicle. The plow plate is pivotally mounted about a vertical axis which is laterally offset to one side of the center-line of the vehicle. In this manner, as the direction in which the vehicle is driven is changed, the plow plate can be pivoted from the front plowing position to the slide plowing position and vice versa. Preferably, such a plow plate is mounted on each end of the vehicle, each plow plate being pivotable about a vertical axis which is offset to the opposite sides of the vehicle center-line.

Dependent claims

In combination with a work vehicle such, for example, as a work vehicle which travels on rails, said work vehicle having first and second ends constituting front and rear ends depending on the direction of movement of the vehicle and a center-line extending in the direction of movement thereof, a plow assembly comprising:

at least one plow plate;
means for pivotally mounting said at least one plow plate on one of said first and second ends of said vehicle so that said plow plate is pivotable through an angle of about 180.degree. between a front plowing position in the track of the vehicle and a slide plowing position on the side of the vehicle about a vertical axis which is laterally offset to one side of said vehicle center-line;
and
means for pivoting said at least one plow plate,
whereby as the driving direction of the vehicle is changed, said plow plate can be pivoted from the front plowing position to the slide plowing position and vice versa.
