Patent
CA 2037202
A mini-size universal hydraulic excavator which is capable of performing independently many operating processes, such as digging, pushing, grabbing, drilling and chipping, comprises essentially three main sections, namely a chassis carrying traveling devices and pivotally connected with an earth-moving means, a complete swivel upper carriage provided with a power generator and a driver's seat, and an excavating arm comprising a boom, a bucket arm, a bucket, etc. The hydraulic chipper can be used by being connected to the main machine without the necessity of removal of the bucket and the earth-moving means, so that chipping and site clearing can be carried on simultaneously solely by one single machine. A backhoe bucket carrying a scraper employs a multi-bar linkage mechanism comprised of a bucket body, a scraper, a bucket arm, etc., so that the bucket can have sufficient bucket capacity in a relatively greater excavating revolving angle range. The specially-set accessory operating equipment oil lines are used to drive all the hydraulic operation equipment except the bucket.
