Abstract
A traveling assembly, especially a wheel suspension, for a vehicle capable of rolling and stepping or walking travel upon a regular or uneven surface, e.g. for cranes, excavators, construction, earth-moving, mining and other machinery in which wheels are articulated at the ends of legs which, in turn, are pivotally connected to a support structure. The legs themselves are formed with telescoping support elements which can be extended and retracted while a fluid-pressure cylinder can be provided to pivot the arm which is articulated to the lower end of the leg and which carries the wheel.

- means for extending said ram from said leg;
- a lever articulated at one end to a lower portion of said leg;
- a wheel journaled on an opposite end of said lever;
- and
- actuating means connected to said lever for swinging said wheel between a position wherein said wheel is drawn away from the ground and a position wherein said wheel supports said leg on the ground.
