A tool for demolishing a column, including a tool frame defining an interior work space. The interior work space is sized and shaped to at least partially surround a portion of the column. A support frame is disposed in the interior work space of the tool frame, the support frame including a tool support that is displaceable within the interior work space. A milling tool is rotatably disposed on the support frame and displaceable therewith to engage the column when the tool frame is positioned around the portion of the column. A hydraulic cylinder is attached between the tool frame and the support frame and configured to forcibly displace the support frame and milling tool within the interior work space. A motor is configured to rotate the milling tool.

Column demolishing tool

A tilt bucket may include a front structure having an outer surface, the front structure including a base plate with a bottom surface. The tilt bucket may include a bottom edge and a curved wrapper extending between the base plate and the bottom edge. A ratio of a maximum distance between the curved wrapper and a first line extending from the bottom edge to the tangent point on the outer surface of the front structure, taken substantially perpendicularly from the first line, relative to a length of the first line, may be about 0.64 to 0.70.

Tilt bucket profile and front structure

A vibratory compactor for a work machine, includes a support frame that defines an interior space and includes a base disposed at a lower end thereof configured to contact a work surface. A guide member is attached to the support frame. A vibratory mechanism includes a vibratory housing and includes a contact plate. The contact plate is configured to compact the work surface. An excitation device is configured to vibrate the contact plate. A guide opening is formed through the vibratory housing configured to movably receive the guide member and to permit the vibratory mechanism vertical movement relative to the support frame. At least one biasing member is disposed between the support frame and the vibratory housing and generates a selected force between the support frame and the vibratory housing when the base is in contact with the work surface.

A machine bucket may include a torque tube having an outer surface. The machine bucket may also include a support plate coupled to the torque tube. The support plate may include a bottom surface. The machine bucket may further include a base edge including a cutting edge. The machine bucket may also include a curved wrapper located between the support plate and the base edge. A ratio of a maximum distance between the curved wrapper and a first line extending from the base edge to the outer surface of the torque tube where the bottom surface of the support plate intersects the outer surface of the torque tube, taken substantially perpendicularly from the first line, relative to a length of the first line, may be about 0.61 to 0.63.

Machine bucket

A machine bucket may include a wrapper. The wrapper may form a portion of a receptacle for holding material. The wrapper may include a curved upper portion defining an arc. The curved upper portion may have a central angle value (&#x3b8;) of between approximately 109.5&#xb0; and 110.5'. The wrapper may also include a curved lower portion defining an arc. The curved lower portion may have a central angle value (&#x3b8;) of between approximately 44.5&#xb0; and 45.5&#xb0;. Such a machine bucket finds particular utility collecting and transporting material that is adherent to itself and the surfaces of the bucket.
