Abstract
Abstract An excavating machine equipped with a shovel at the end of a jib pivotally fastened to a vehicle frame has an approximately Ushaped front axle assembly including a normally horizontal beam projecting far from the frame and carrying vertically adjustable columns on which the front idler wheels may be pivoted in the upright plane of the U-shape. Rear legs of adjustable height are similarly spread far apart to permit the machine to travel on oppositely inclined lateral slopes of a ditch during excavation work.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
210 words
In an excavating machine having a normally horizontally extending frame, a platform rotatable on said frame about an upright axis, a jib having one end pivotally fastened to said platform and carrying an excavating tool at the other end thereof, and supporting means for holding said frame in a position upwardly spaced from the ground, the improvement in the supporting means which comprises: a. a front axle assembly at one end of said frame, said assembly including 1. a normally horizontally elongated beam member projecting beyond said frame in two opposite directions and having two free ends, 2. an elongated column member vertically extending downwardly from each of said free ends, 3. a wheel mouNted at the lower end of each column member for rotation about an axis extending in said directions, the length of the column member being greater than the diameter of the wheel mounted thereon; b. two leg assemblies at the other end of said frame, said leg assemblies being spaced from said front axle assembly transversely of said direction; c. securing means securing said beam member to said frame for longitudinal movement; and d. connecting means for fixedly connecting said beam member to said frame in a plurality of positions offset longitudinally of said beam member.
Claim 2
Dependent Claim
