Abstract

1,167,061. Endless-track vehicles. RAYMOND INTERNATIONAL Inc. 4 Jan., 1967 [13 Jan., 1966], No. 430/67. Addition to 1,123,631. Heading B7H. [Also in Division E1] The derrick described and claimed in the parent Specification is improved or modified in that the means for moving the traction units relative to each other in a lateral direction comprises arm supports 106, 116, Fig. 3, pivotally connected to the traction units 26 and the base 12 by pins 110, 114, 116, 120, the pins 114, 118 on either side of the base being interconnected by a collapsible supporting link e.g. an hydraulic piston-and-cylinder unit 122. Alternatively, the means aforesaid comprises for each traction unit a pair of arm supports 138, Fig. 5, pivotally connected to the said unit and the base by pins 142, 146, bolts 154 for attaching a bearing member 144 to a web 152 on the traction unit being inserted and secured when the traction unit is to be locked in a desired position relative to the base and extracted when said unit is to be moved so as to allow the member 144 to slide along the web.
