Abstract

1443205 Mining equipment COAL INDUSTRY (PATENTS) Ltd 21 June 1974 [27 July 1973] 35851/73 Heading E1F A boom assembly 18 for a mining machine suspended from an overhead track 3 has a bracket 30 for mounting a rock breaking tool 37 or a bucket 36. A carriage assembly 6 is mounted on the track 3 by shoes 9 and 10 and comprises components 7 and 8 pivotally connected to one another by a pin 5 to negotiate misalignment in the track. The component 7 has a slideway 12 on which is slidably mounted a slide assembly 13; having a support 16. The support 16 is -mounted for pivotal movement in a horizontal plane and pivotally carries the boom assembly 18, the end of the latter being rotatable about its longitudinal axis.
