Abstract
A mobile rig on wheels with transverse motion, in particular a telescoping stacker, having a first axle mounted on a rigid vehicle frame and a second axle disposed transversely movably on the vehicle frame to describe a circular translation. Advantageously, the second axle is disposed on the vehicle frame by parallel links and the parallel links can be swivelled through vertical axes by swivel actuation device.
Claims20
A mobile rig comprising:
- a) a rigid vehicle frame having a longitudinal axis;
- b) a telescoping stacker operably mounted to said frame;
- c) a first axle mounted on said vehicle frame, said first axle supporting a first pair of wheels;
- and,
- d) a second axle mounted on said vehicle frame a distance from said first axle, said second axle supporting a second pair of wheels, said second axle movable laterally and longitudinally relative to said vehicle frame to provide parallel displacement of said second axle relative to said first axle wherein the distance between said first axle and said second axle is selectively varied.

A mobile rig comprising:
- a ) a rigid vehicle frame having a longitudinal axis;
- b) a telescoping stacker operably mounted to said frame;
- c) a first axle mounted on said vehicle frame, said first axle supporting a first pair of wheels;
- and
- d) a second axle mounted on said vehicle frame a distance from said first axle, said second axle supporting a second pair of wheels, said second axle selectively movable laterally and longitudinally relative to said vehicle frame to provide said second axle with circular translation whereby the distance between said first and second axles is selectively variable upon parallel displacement of said second axle relative to said first axle.

A mobile rig comprising:
- a) a rigid vehicle frame having a longitudinal axis;
- b) a telescoping stacker operably mounted to said frame;
- c) a first axle mounted on said vehicle frame, said first axle supporting a first pair of wheels;
- and
- d) a second axle mounted on said vehicle frame a distance from said first axle, said second axle supporting a second pair of wheels and selectively movable both laterally and longitudinally relative to said vehicle frame so that the distance between said first and second axle is adjustable while said first and second axles are maintained in parallel alignment.
