20110056099 | METHOD AND APPARATUS FOR CONTROLLING THE DEPTH OF CUT OF A TRACKHOE BUCKET - An apparatus for controlling the depth of a hoe bucket, including a hoe bucket defining a cutting edge, an elongated member pivotably connected to the bucket, an actuator operationally connected to the elongated member, an electronic controller operationally connected to the actuator, and a position sensor operationally connected to the cutting edge and operationally connected to the electronic controller. The actuator may be energized to pivot the elongated member to a position adjacent the cutting edge for engaging ground, and positioning of the elongated member adjacent the cutting edge prevents the cutting edge from digging ground. | 03-10-2011 |
20110088920 | ATTACHMENT SYSTEM AND LEVELER ATTACHMENT FOR A MECHANICAL HOE - A screed assembly for attachment to the boom arm of a mechanical hoe, including a first elongated member, an elongated ground-engaging structural member extending therefrom, a hoe connection interface and a hydraulic boom connection interface on the first elongated member, and a blade-engaging assembly operationally connected to the first elongated member. An elongated blade portion is pivotably connected to the blade-engaging assembly, a first pivot actuator is operationally connected between the first generally elongated portion and to the blade-engaging assembly, and a second pivot actuator operationally connected to the blade-engaging assembly and the elongated blade portion. Energization of the first pivot actuator pivots the blade engaging assembly relative to the first elongated member and energization of the second pivot actuator pivots the blade relative to the blade-engaging assembly. | 04-21-2011 |
20120066941 | ELONGATED NARROW TRENCHING SCOOP ATTACHMENT FOR A BACKHOE AND METHOD FOR USING THE SAME - An elongated digging attachment for an excavator, including a recessed main body portion, a connection assembly connected to the main body portion, and a ground engaging portion connected to the main body portion and oppositely disposed from the connection assembly. The recessed main body portion defines a concave curvature, the recessed main body portion and the ground engaging portion define a scoop, and the scoop has an aspect ratio of at least about 1:3. | 03-22-2012 |
20120186837 | FIREFIGHTING ATTACHMENT FOR AN EXCAVATOR AND METHOD FOR USING THE SAME - A back hoe attachment for insertion into a burning structure for delivering a water spray, including an elongated hollow tube portion having a tube distal end and a tube proximal end, an elongated blade portion connected to the elongated hollow tube portion and disposed generally parallel to the elongated blade hollow tube portion, a water hose connection interface connected to the tube proximal end, a water diverting portion operationally connected to the tube distal end, and a back hoe connection interface portion operationally connected to the elongated blade member. | 07-26-2012 |
20140222301 | APPARATUS FOR ADAPTING A HOE BUCKET FOR DEPTH CONTROL - A kit for modifying a digging bucket for controlling the depth cut, including an elongated member operationally connectable to a hoe bucket defining a cutting edge, an actuator operationally connectable to the elongated member, an electronic controller operationally connectable to the actuator, and a position sensor operationally connectable to the cutting edge and operationally connectable to the electronic controller. The actuator may be energized to pivot the elongated member to a position adjacent the cutting edge for engaging ground. Positioning of the elongated member adjacent the cutting edge prevents the cutting edge from digging ground. | 08-07-2014 |
20140237866 | APPARATUS FOR ADAPATING A HOE BUCKET FOR DEPTH CONTROL - A kit for modifying a digging bucket for controlling the depth cut, including an elongated member operationally connectable to a hoe bucket defining a cutting edge, an actuator operationally connectable to the elongated member, an electronic controller operationally connectable to the actuator, and a position sensor operationally connectable to the cutting edge and operationally connectable to the electronic controller. The actuator may be energized to pivot the elongated member to a position adjacent the cutting edge for engaging ground. Positioning of the elongated member adjacent the cutting edge prevents the cutting edge from digging ground. | 08-28-2014 |
20150081176 | APPARATUS AND METHOD FOR ENHANCED GRADING CONTROL - A method of operating a digging machine, including damping the response of a boom hydraulic cylinder operationally connected to a boom arm and actuating a bucket hydraulic cylinder operationally connected to a bucket. | 03-19-2015 |
20160017571 | VALVE SYSTEMS AND METHOD FOR ENHANCED GRADING CONTROL - A method of operating a digging machine, including operationally connecting a sensor to a bucket, operationally connecting an electronic controller to the sensor and to each respective hydraulic cylinder, operationally connecting a valve system to the hydraulic cylinder and to the electronic controller, inputting a desired post excavation landscape contour into the electronic controller, inputting locations of underground objects into the electronic controller, automatically actuating a bucket hydraulic cylinder operationally connected to the bucket, and automatically controlling the bucket hydraulic cylinder to dig within predetermined parameters. | 01-21-2016 |
