Definitions
- the slide frame 116 is retained for sliding along and for clamping engagement with the main frame 14 by means of complementary counterfaces on the respective frames. These counterfaces take the form of a transverse guide rail 70 at the top front of the main frame 14 which is received in a recess 72 in the underside of the projection 40 of the slide frame 16 and a guide groove 74 in the lower rear of the main frame 14 into which is disposed a forward projection 76 of the slide frame 16.
- a mechanical digger including a mobile vehicle, a transverse main frame supported on the vehicle and having guide means extending transversely therealong, and a slide frame mounted for movement along said guide means
- the improvement comprising releasable clamping means for selectively clamping the slide frame to said main frame including at least one hydraulically loadable piston carried by said slide frame, control valve means for selectively connecting said piston to a source of fluid pressure or to a fluid return including a valve bore intersected by axially spaced supply and exhaust bores and having an inlet for connection to a source of fluid pressure, said supply and exhaust bores being respectively in fluid communication with said piston and return, a first valve seat and check valve in said valve bore between said inlet and supply bores and a second valve seat and check valve in said valve bore between said supply and exhaust bore, bias means urging said first and second check valves against the first and second valve seats for preventing slow between the inlet and supply bores and the supply and exhaust bores, respectively, said bias means having a force lesser than the inlet
