摘要： A mini-size universal hydraulic excavator capable of performing independently many operating processes, such as digging, pushing, grabbing, drilling and chipping, having essentially three main sections, namely, a chassis carrying traveling device 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 having a boom, a bucket arm, and a bucket. A hydraulic chipper can be 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 having a bucket body, a scraper, and a bucket arm so that the bucket can have sufficient bucket capacity in a relatively greater excavating revolving angle range. Specially-set accessory operating equipment oil lines are used to drive all the hydraulic operation equipments except the bucket.
