Abstract

1291318 Excavator buckets POCLAIN 25 Aug 1970 [29 Sept 1969] 40829/70 Heading E1F [Also in Division B8] A material-moving machine comprises a pivoted bucket 1 operated by a double-acting hydraulic jack 4 and having teeth 8 operated by one or more hydraulic hammers 10, the jack and the hammer or hammers being connected in parallel to a source of pressurized fluid and the arrangement being such that the bucket is pivoted with its cutting edge leading while the hammer or hammers are operated simultaneously. The jack and hammers are supplied through conduits 16, 18 and a non- return valve 17 isolates the hammers from the source of pressurized fluid when the bucket is moved in the opposite direction. The common non-return valve 17 may be replaced by a non-return valve in each of the conduits 13a, 13b, 13c leading from the hammers, Fig. 3 (not shown). The bucket may be a suspended grab bucket.
