Abstract
In a double articulated vehicle, such as for use in low overhead clearance areas, a front and rear frame are pivotally mounted to an intermediate carriage in such a way that both frames will turn in the same direction upon actuation of the steering mechanism. A cab is removably mounted on sound suppressing shock mounts on the side of the intermediate carriage with the floor of the cab substantially coterminous with the bottom of the carriage and with the roof of the cab substantially coterminous with the highest projections on the front and rear frames. The cab will face in a direction transverse to the lengthwise centerline of the vehicle and be protected by and from the wheels on one side of the vehicle.
Claims12
In a double articulated vehicle having a carriage with a top, a bottom, a front, a rear and two sides, said carriage having a longitudinal axis running lengthwise from the front to the rear thereof, a front frame pivotally connected to the front of said carriage, a rear frame pivotally connected to the rear of said carriage in line with said front frame, said pivotal connections lying on said longitudinal axis of said carriage, a pair of wheels drivingly connected to said rear frame, a pair of wheels drivingly connected to said front frame, and means for interconnecting said front and rear frames for simultaneous turning, in combination a cab having a front window and side windows, means for removably mounting said cab on one of said sides of said carriage with said front window facing transverse to said longitudinal axis of said carriage, said cab having an upper extremity defined by the upper extremities of said front window and said side windows which upper extremity lies in a plane that is substantially coterminous with the highest fixed projection on the vehicle.
A double articulated vehicle having a carriage with a longitudinal axis running the length thereof, said carriage having two sides lying substantially parallel to said longitudinal axis, a front frame pivotally connected to said carriage, a rear frame pivotally connected to said carriage, a cab having operator enclosing sides with the upper edges of said enclosing sides defining an upper extremity to said cab, means for mounting said cab on one of said sides of said carriage with the front of said cab facing in a direction transverse to the longitudinal axis of said carriage, said cab having said upper extremity lying below the highest fixed structural projection on the front frame, rear frame and carriage.
In a double articulated vehicle having a carriage with a pair of opposite sides, a front frame pivotally connected to said carriage, a rear frame pivotally connected to said carriage, a pair of wheels drivingly connected to opposite sides of said rear frame, a pair of wheels drivingly connected to opposite sides of said front frame, means for interconnecting said front and rear frames for simultaneous turning, a cab, means for removably mounting said cab on one of said sides of said carriage with the front of said cab facing in a direction transverse to said carriage, said last-named means comprising interfitting lugs and flanges on said cab and on said carriage, resilient means mounted in each of said lugs, and pins passing through said flanges and through said resilient means in said lugs whereby shock and sound from the vehicle will not be transmitted through said resilient means to said cab and wherein the extremities of said cab is within the outline of said front and rear frames and within the turning radius of the wheels on the side of said vehicle upon which the cab is mounted.
A double articulated vehicle having a carriage with a longitudinal axis running the length thereof, said carriage having two sides lying substantially parallel to said longitudinal axis, a front frame pivotally connected to said carriage, a rear frame pivotally connected to said carriage, a cab having a front, a back, and two sides with the upper edges of said front, back and sides defining an upper extremity to said cab, means for mounting said cab on one of said sides of said carriage with the front of said cab facing in a direction transverse to the longitudinal axis of said carriage, said cab having said upper extremity lying substantially coterminous with the highest major fixed projection on the front frame, rear frame and carriage.
