Abstract
Abstract A self propelled, articulated vehicle having a rock drilling unit mounted upon one section. The rock drilling unit is directly mounted to a ground engaging stabilizer unit which is pivotally secured to the section whereby the stabilizer unit may be raised for moving the entire vehicle from place to place. The stabilizer unit will be placed in a ground contacting position during the operation of the rock drill whereby vibration and shock is transmitted to the ground instead of to the vehicle. The vehicle is entirely self contained in that it has a compressor and other equipment necessary for the rock drilling operation.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
171 words
A self propelled mobile rock drilling vehicle comprising; an articulated frame having powered wheels on each section, means for varying the angularity between the sections to control direction during travel, a power source mounted upon one section for driving both the vehicle and an air compressor mounted upon the vehicle, an operator''s station mounted upon one section, stabilizer means mounted to one section and adapted to be placed in contact with the ground whenever the drill is in operation and be lifted clear of the ground for travel, rock drilling means mounted upon the stabilizer whereby when the rock drill is in operation the vibration and shock of the drilling operation is transmitted through the stabilizer to the ground instead of to the vehicle thereby effectively isolating the operator and controls from the vibration, and means connecting the compressor to the rock drill, whereby the vehicle may be rapidly moved from place to place and perform its function independently of other equipment and without excess vibration being transmitted to the operator.
Claim 2
Dependent Claim
171 words
A self propelled mobile rock drilling vehicle comprising; an articulated frame having powered wheels on each section, means for varying the angularity between the sections to control direction during travel, a power source mounted upon one section for driving both the vehicle and an air compressor mounted upon the vehicle, an operator''s station mounted upon one section, stabilizer means mounted to one section and adapted to be placed in contact with the ground whenever the drill is in operation and be lifted clear of the ground for travel, rock drilling means mounted upon the stabilizer whereby when the rock drill is in operation the vibration and shock of the drilling operation is transmitted through the stabilizer to the ground instead of to the vehicle thereby effectively isolating the operator and controls from the vibration, and means connecting the compressor to the rock drill, whereby the vehicle may be rapidly moved from place to place and perform its function independently of other equipment and without excess vibration being transmitted to the operator.
Claim 3
Dependent Claim
27 words
A vehicle as in claim 1 wherein the power source drives an hydraulic pump which is connected to a hydraulic motor which in turn drives the wheels.
Claim 4
Dependent Claim
23 words
A vehicle as in claim 1 wherein the power source drives an hydraulic pump which drives a motor directly connected to each wheel.
Claim 5
Dependent Claim
38 words
A vehicle as in claim 1 wherein the stabilizer means is mounted to the same section as the operator''s station and is in the form of an earthmoving blade whereby the vehicle can also serve to move debris.
Claim 6
Dependent Claim
39 words
A vehicle as in claim 4 wherein the controls for the stabilizer means, the vehicle movement and the drill operation are at the operator''s station which is located such that the operator may control all functions from one place.
Claim 7
Dependent Claim
44 words
A self propelled mobile rock drilling vehicle as in claim 1 wherein the stabilizer means is a blade and includes a platform mounted turntable to which the drill is mounted whereby the drill may be moved to a position overlying the vehicle for travel.
Claim 8
Dependent Claim
134 words
A rapidly movable self propelled rock drilling vehicle comprising; at least two articulatable sections secured together for relative movement and including means to control the relative position whereby the vehicle may be steered, a blade movable from a ground contacting position to a raised traveling position secured to the end of one of the sections, said blade having a platform upon the upper portion thereof, a rock drill mounted upon a turntable based upon the platform, a power source mounted to the vehicle and adapted to drive the vehicle, a hydraulic pump fOr other operating functions and a compressor for the rock drill, and an operator''s station upon one of the sections wherein the operator can drive the vehicle, control the position of the blade and operate the rock drill from a single position.
Claim 9
Dependent Claim
134 words
A rapidly movable self propelled rock drilling vehicle comprising; at least two articulatable sections secured together for relative movement and including means to control the relative position whereby the vehicle may be steered, a blade movable from a ground contacting position to a raised traveling position secured to the end of one of the sections, said blade having a platform upon the upper portion thereof, a rock drill mounted upon a turntable based upon the platform, a power source mounted to the vehicle and adapted to drive the vehicle, a hydraulic pump fOr other operating functions and a compressor for the rock drill, and an operator''s station upon one of the sections wherein the operator can drive the vehicle, control the position of the blade and operate the rock drill from a single position.
Claim 10
Dependent Claim
26 words
A vehicle as in claim 7 wherein the rock drill is movable to a position overlying one of the sections for travel from place to place.
