Estimating the term…
A working apparatus includes a body, an engine, a front axle and a rear axle, the axles each carrying ground engaging wheels or tracks on which the apparatus may move over the ground, the apparatus further including an operator's cab mounted on the body, and there being at least one working arm supported at or adjacent one end on the body at a position for movement relative to the body, the arm being adapted to carry a working implement at or adjacent a second end thereof, and wherein one of the front and rear axles is suspended from the body by suspension means which is adjustable independently of the other axle to raise the body to a fully raised position in which a plane in which an uppermost part of the body lies, is at a maximum height above the ground and a fully lowered position in which the is at a minimum height above the ground.
A working apparatus including a body, a power operated motive means, a front axle and a rear axle, the axles each carrying ground engaging means on which the apparatus may move over the ground, the apparatus further including an operator's cab mounted on the body, and there being at least one working arm supported at or adjacent one end on the body at a position for movement relative to the body, the arm being adapted to carry a working implement at or adjacent a second end thereof, and wherein one of the front and rear axles is suspended from the body by suspension means which is adjustable independently of the other of the axles to raise the body relative to the one of the front and rear axles only to a fully raised position in which a plane in which an uppermost part of the body lies, is at a maximum height above the ground and a fully lowered position in which the plane is at a minimum height above the ground.
A working apparatus including a body, a front axle and a rear axle, each axle carrying a pair of ground engaging means, one at or towards each end of the axle, front axle mounting means mounting the front axle relative to the body, and rear axle mounting means mounting the rear axle relative to the body, the working machine being operable in at least two operating modes in each of which the machine may move over the ground namely a first mode in which the front and rear axles are suspended from the body by their respective mountings such that the front and the rear axles are movable relative to the body in response to irregularities in terrain, and a second mode in which one of the front and rear axles is suspended from the body by the respective axle mounting means whilst the other of the axles is constrained to oscillate about a longitudinal axis which is substantially fixed relative to the body in response to irregularities in terrain.
A working apparatus including a body, a front axle and a rear axle, each axle carrying a pair of ground engaging means, one at or towards each end of the axle, front axle mounting means mounting the front axle relative to the body, and rear axle mounting means mounting the rear axle relative to the body, the working machine being operable in at least two operating modes in each of which the machine may move over the ground namely a first mode in which the front and rear axles are suspended from the body by their respective mountings such that the front and the rear axles are movable relative to the body in response to irregularities in terrain, and a second mode in which one of the front and rear axles is held generally rigid relative to the body by the respective axle mounting means whilst the other of the axles is constrained to oscillate about a longitudinal axis which is substantially fixed relative to the body in response to irregularities in terrain.
A working machine including a body, a front axle and a rear axle, each axle carrying a pair of ground engaging means, one at or towards each end of the axle, front axle mounting means mounting the front axle relative to the body, and rear axle mounting means mounting the rear axle relative to the body, the working machine being operable in three alternative operating modes in each of which the machine may move over the ground namely a first mode in which the front and rear axles are suspended from the body by their respective mountings such that the front and the rear axles are movable relative to the body in response to irregularities in terrain, a second mode in which one of the front and rear axles is suspended from the body by the respective axle mounting means whilst the other of the axles is constrained to oscillate relative to about a longitudinal axis which is substantially fixed relative to the body in response to irregularities in terrain and a third mode in which one of the front and rear axles is held generally rigid relative to the body by the respective axle mounting means whilst the other of the axles is constrained to oscillate about a longitudinal axis which is substantially fixed relative to the body in response to irregularities in terrain.
A method of operating a working apparatus which includes a body, a power operated motive means, a front axle and a rear axle, the axles each carrying ground engaging means on which the apparatus may move over the ground, the apparatus further including an operator's cab mounted on the body, and there being at least one working arm supported at or adjacent one end on the body, the working arm being moveable relative to the body and being adapted to carry a working implement at or adjacent a second end thereof, and wherein at least one of the front and rear axles is suspended from the body by suspension means, the method including adjusting one only of the front and rear suspension means, to move the body relative to the ground between a fully raised position in which a plane in which an uppermost part of the body lies is at a maximum height above the ground and a fully lowered position in which the plane is at a minimum height above the ground.
An axle adapted to carry a pair of ground engaging means, and to mount a suspension component, wherein the axle includes an axle body part, having a first formation by means of which a mounting member may be secured to the main body part, and the suspension component is attached to the main body part via the mounting member.
A working apparatus having a front axle carrying ground engaging means and a rear axle carrying ground engaging means, at least one of the axles being an axle adapted to carry a pair of ground engaging means, and to mount a suspension component, wherein the axle includes an axle body part, having a first formation by means of which a mounting member may be secured to the main body part, and the suspension component is attached to the main body part via the mounting member.
