An attachment for a machine having a handle, operable to perform various groundworking functions, generally consisting of an arm member pivotally connectable to the handle of the machine, an extendable strut pivotally connected to the arm member and pivotally connectable to the handle when the arm member is connected to the handle of the machine and at two tools, any selected one of which is detachably mountable on the arm member.

A work machine for achieving efficient coordinated operations by a plurality of kinds of operating units, comprising first and second swivel driving members and first and second swivel joints, wherein a first swiveling base bearing a first operating unit and a second swiveling base bearing a second operating unit can swivel around a common swiveling axis independently relative to a traveling base.

A winch attachment for a backhoe replaces a bucket normally carried on the backhoe boom to allow the backhoe to engage in winching operations. The winch attachment includes a winch bracket which is detachably secured to the mounting bracket on the end of the boom where the bucket is normally mounted. The winch bracket includes a pivotally mounted frame carrying the winch drum and cable so that the winch can be pivoted to the side when necessary. Quick connect hydraulic couplings are applied to t...

Disclosed is an excavating machine, representatively a tracked excavator, having a boom stick portion on which both an excavating bucket and a hydraulic breaker are mounted for hydraulically driven pivotal movement between first and second limit positions. The bucket may be operated independently of the breaker for digging operations. Similarly, the breaker may be operated independently of the bucket for refusal material-breaking operations. The same excavating machine may now use the bucket and...

The current invention describes a tool mounting device that permits a rotating attachment of a tool to an excavator arm in such a way that the tool can be used for work in relatively small work spaces, independent of the alignment of the excavator arm and the excavator.

An excavating machine, representatively a tracked excavator has a boom stick portion on which both an excavating bucket and a hydraulic breaker are mounted for hydraulically driven pivotal movement between first and second limit positions. The bucket may be operated independently of the breaker for digging operations. Similarly, the breaker may be operated independently of the bucket for refusal material-breaking operations. The same excavating machine may now use the bucket and breaker in a rap...

A crane-excavator apparatus and method is provided. More particularly, the present invention relates to a mobile apparatus adaptable for use as a crane and as an excavator, and an associated method. The crane includes a lower crawler adapted for use with an excavator, an upper body adapted for use with an excavator, a boom adapted to engage a crane body, and an adapter for engaging a receptacle of the excavator upper body. Typically, the receptacle would accept an excavator boom. The adaptor and...

An excavator assembly 10 including an excavator body having a pair of tracks 12 an 13, a cab 14, an articulated boom 15 and a trenching or cutting attachment 16 mounted at the end of the boom 15. The trenching or cutting attachment comprises a blade 17 mounted to a box-like drive mounting 18 with the box-like mounting 18 having on an opposite side thereof an excavator mounting 19 element so that the attachment can be detached from the excavator. A swivel arrangement is provided for swivelling th...
