A grappling apparatus usable with a vehicle is provided. The grappling apparatus includes a connection assembly, a grappling assembly and a stabilizing assembly. The connection assembly connects the grappling apparatus to the vehicle. The grappling assembly has an upper claw assembly and a lower claw assembly. The upper claw assembly has a first plurality of manipulator arms and a walking gear. The lower claw assembly has a second plurality of manipulator arms and a stabilizer gear. The walking gear is meshable with the stabilizer gear and the first and second plurality of manipulator arms are operably connected to the walking gear and the stabilizer gear so as to be moveable between a closed position and an open position. The stabilizing assembly has a stabilizer bar operably connected to the second plurality of manipulator arms and the vehicle so as to stabilize the at least one stabilizer gear.

A device for securing logs from harvested timber to a transport vehicle, or logging truck, using log wrappers. The log wrapper securement device can be located in the inspection cavity of a forestry grapple. The forestry grapple is attached to a log loader. The log wrapper securement device includes a base plate sized and shaped to replace the inspection plate covering the inspection cavity. The base plate includes a slot sized and shaped to receive a portion of a chain end link or other chain links of the log wrapper, which can be inserted manually. The loader operator can remotely control the actuator to secure the chain link and release it, once the log wrapper is positioned over the other side of the logging truck. The log wrapper securement device can potentially reduce injuries and save lives.

A shovel includes a lower traveling body, an upper turning body turnably mounted on the lower traveling body, an object monitoring device attached to the upper turning body, an attachment attached to the upper turning body, a hook attached to the attachment, and a hardware processor. The hardware processor is configured to switch the operating mode of the shovel to a crane mode based on information obtained by the object monitoring device.

A control system configured to control movement of a hydraulically operated crane assembly and a crane tool of a work vehicle with a primary power source and a hydraulic working system. The control system configured to calculate a deviation between an actual value and a predetermined target value of a lifting movement of the crane assembly, and configured to control the crane assembly to fulfill the predetermined target value.

A grapple for mounting to a boom of a boom crane includes a body member for mounting to the end of a boom of a boom crane including a first wing member and a second wing member and opposing first and second jaw members. Each jaw is hingably coupled to the body member, and hinges with respect to the body member by the action of a hydraulic cylinder. A first end of the hydraulic cylinder is coupled to the jaw member and a second end of the hydraulic cylinder is coupled to a portion of one of the wing members. The first and second wing members extend to position the second end of each hydraulic cylinder rearward of an end of the boom of the boom crane or a coupling between the body member and the boom of the boom crane.

A mobile conductor lift comprised of multiple lightweight subassemblies that may be rapidly assembled manually or using handheld tools by a small crew of workers and that is capable of being quickly and easily placed into multiple potential configurations and in either horizontal or vertical orientations for lifting energized or deenergized conductors away from power poles in order to provide room for work to be performed by workers on such power poles or on other equipment connected to such power poles.

Embodiments of the present disclosure disclose a drive for an electric clutch if a winch. The drive comprises a pusher block having a first end, a second end, and a transmission component arranged on a central portion of the pusher block to drive a transmission shaft; a first driving unit connected to the first end to drive the first end to reciprocate between a first position and a second position; and a second driving unit connected to the second end to drive the second end to reciprocate between a third position and a fourth position. The drive enables switching of the transmission shaft between a high speed mode, a low speed mode, and an idle mode. A winch including the drive is also disclosed.
