Abstract

1463677 Endless-track vehicles; adjusting track width POCLAIN 19 Sept 1974 [25 Oct 1973] 40877/74 Headings B7H and B7D [Also in Division E1] In a telescopic beam for connecting an endless-track frame to the main frame of a shovelling machine or for forming a telescopic jib on a mobile crane, an hydraulic ram 16 is connected between two slidably-engaged beam sections 2, 3 for varying the relative position of the sections, a locking pin 11 carried by the section 3 is spring-loaded for engagement with either of two apertures 8 in the section 2 to lock the sections in first and second relative positions, and a pivotable element 4 connecting the ram 16 to the section 2 is arranged so that pivoting of the element consequent upon operation of the ram 16 to vary the relative position of the sections 2, 3 results in one of two fingers 10 carried by the element being introduced into the appropriate aperture 8 to automatically disengage the locking pin 11 from that aperture so that the sections can be moved from the first to the second position or vice versa. In Fig. 4 endless-track frames 25 are each connected to the central main frame 2 of a shovelling machine by a pair of telescopic beams 1, the inboard sections 3 being common to the beams on opposite sides of the vehicle. By selective operation of the rams 16 to vary the lengths of the beams on one or both sides it is possible to obtain three effective track widths.
