Abstract

1310170 Supporting device for mobile excavators and cranes WEIMAR-KOMBINAT VEB 23 June 1970 30407/70 Heading B7J A supporting device, for mobile excavators and cranes, comprises a central carrier 1 upon which are pivotably mounted two outer carriers 3 which house hydraulically extensible and retractable arms 4; the arrangement is such that on extension of the arms 4 by piston and cylinder devices 6, the carriers 3 pivot downwards until pivotable support feet 5 on each arm find secure hold on the ground, the pivoting movement of the carriers being limited by stops 7 and 8 and the carriers being locked by pivoted catches 9. Upon retraction, the arms 4 contact and release the catches 9 to allow upward pivoting of the carriers 3.
