A modular lifting system, including an enclosable lifting device support structure. The enclosable lifting device support structure includes a deployable top, a plurality of lateral sides, a base coupled to the plurality of lateral sides, and a plurality of extension arms. The deployable top is configured to support a lifting device on a first side of the deployable top. The plurality of extension arms are configured to extend and support the deployable top when the deployable top is deployed.

A system for rotating a vessel may include a container assembly. An exemplary container assembly may include a head end frame that may be spaced apart from and interconnected with a tail end frame. An exemplary container assembly may be configured to encompass and hold the vessel or a portion of the vessel. An exemplary system for rotating a vessel may further include a linear actuating mechanism that may be coupled to a bottom edge of the tail end frame. An exemplary linear actuating mechanism may be configured to drive a translational movement of the bottom edge of the tail end frame along a first axis. An exemplary system for rotating a vessel may further include a double-pivot link that may be pivotally connected between a top edge of the head end frame and a fixed revolute joint. An exemplary double-pivot link may be configured to rotate the top edge about the fixed revolute joint responsive to the translational movement of the bottom edge of the tail end frame along the first axis.

A grabbing device having a plurality of jaws which can be moved between an open position and a closed position to enable the device to grasp an object(s). The technology finds particular application in the forestry industry and moving logs.

Group online communication and collaboration has become part of people's daily life. Therefore, it is critical to provide a meeting initiator to efficiently present his/her information, and control his/her presented information. It is also critical for the speed and efficiently to process the meeting initiator's requests for his/her presented information to be quickly reaching to other meeting participants during a meeting. This invention facilitates a unique user interface (UI) for the meeting initiator to efficiently present information and to control presented information through a unique withdrawing (un-post) operation. Specially, this invention deploys dynamic workspaces technology together with post and un-post (withdraw) operations that greatly improves the speed and efficiency for processing the meeting initiator's requests and for monetizing the meeting activities.

An arrangement with a lock and an anchor for forming a lifting connection for lifting a load. The anchor has a pin connectable to the load, and an anchor head that adjoins the pin and projects beyond the pin transversely to its longitudinal extension. The lock has an elongated hole with an insertion section and a holding section adjoining the insertion section and differing in its clear width from the insertion section. The elongated hole has a cross section in its insertion section such that the anchor head, in an insertion position, can be guided through this cross section, and the anchor inserted into the insertion section is rotatable around the longitudinal axis of the pin. The anchor head cannot be guided out of the insertion section in a locking position which is rotated by a certain angular amount around the longitudinal axis of the pin relative to the insertion position. The anchor is only displaceable in its locking position in the holding section and, when inserted therein, cannot be rotated around the longitudinal axis of the pin by the angular amount back into the insertion position.

There is disclosed a system and methods of use for quickly and efficiently excavating, cross-cutting, splitting, and loading or stockpiling tree stumpage and other tree or organic materials, as well as for performing ground cleanup operations. One embodiment provides a stump harvester for attachment to a distal end of an excavator arm. The stump harvester may include front and back jaw assemblies configured to pivot between open and closed positions. The back jaw assembly may include a knife arm having a cutting blade that extends along a majority of a front side of the knife arm. A centerline plane may bisect a cutting edge of the blade. The front jaw assembly may include a planar-aligned dual anvil configured to sheath the cutting edge of the blade when the front and the back jaw assemblies move into the closed position. Other embodiments are disclosed.
