Abstract
An undercarriage having tracks or the like is attached thereto is provided for moving the undercarriage along the ground. A turret is attached to the undercarriage along a first substantially vertical axis so that the turret can rotate. A backhoe is pivotally attached to the turret along a second substantially vertical axis. A trencher is operatively attached to the turret and occupies an area adjacent the undercarriage. Structure is provided for preventing the backhoe from moving into an area occupied by the trencher.
Claims12
An excavator comprising:
- (a) an undercarriage;
- (b) a turret operatively attached to the undercarriage, said turret being capable of unlimited rotation around a substantially vertical axis;
- (c) a backhoe operatively attached to said turret;
- (d) a trencher operatively mounted to said undercarriage;
- and
- (e) a first component on the turret and a second component on the trencher wherein the first and second components cooperate to restrict the rotation of the turret such that the turret cannot rotate into a zone where the backhoe interferes with the trencher.
3 more elements
An apparatus comprising:
- (a) an undercarriage;
- (b) means operatively attached to said undercarriage for moving the undercarriage along the ground;
- (c) a turret operatively rotatably attached to the undercarriage along a first substantially vertical axis;
- (d) a backhoe operatively pivotally attached to the turret along a second substantially vertical axis;
- (e) a trencher operatively attached to the undercarriage and occupying an area adjacent the undercarriage;
- and
- (f) means operatively attached to at least one of the turret and the undercarriage for automatically preventing the backhoe from moving into an area occupied by the trencher.
4 more elements
An excavator comprising:
- (a) an undercarriage;
- (b) a turret capable of unlimited rotation around a swivel axis defined in the undercarriage including a stop;
- and
- (c) a chain trencher including a trencher attachment frame for mounting to the undercarriage, the trencher attachment frame including at least one component that cooperates with said stop on the turret to restrict the rotation of the turret whenever the trencher is mounted to said excavator.
1 more element
An excavator comprising:
- (a) an undercarriage;
- (b) a turret operatively attached to the undercarriage, said turret being capable of unlimited rotation around a substantially vertical axis;
- (c) a backhoe operatively attached to said turret;
- (d) a trencher operatively mounted to said undercarriage;
- (e) a sub-frame selectively attached or detached from said undercarriage, said sub-frame having the trencher operatively attached thereto;
- (f) a pair of stop members operatively attached to the sub-frame;
- and
- (g) a pair of stop brackets operatively attached to the turret for contact with respective ones of said stop members when the turret rotates, whereby the rotation of the turret is limited when the sub-frame is attached to the undercarriage.
