A grappler assembly having an assembly framework and a grappler device that is supported by the assembly framework. The grappler device has at least one pair of grappler arms that engages with a desired section of a tree to be removed. The grappler assembly incorporating its own independent power module for supplying hydraulic power to the grappler device and controlling operation of the at least one pair of grappler arms, and the power module is mounted solely to the assembly framework.

A container-handling vehicle for picking up storage containers from a three-dimensional grid of an underlying storage system includes a vehicle body and at least one lifting device with a lifting frame with gripper elements for releasable connection to a storage container, and a transmitter for communicating instructions for controlling the gripper elements. The lifting frame includes a first rechargeable power supply for supplying energy to the gripper elements. The container handling vehicle has at least one second rechargeable power supply configured to charging the first rechargeable power supply when the lifting frame is in a top most position. The at least one second rechargeable power supply is connected to at least one upper charger connector and the first rechargeable power supply is connected to at least one lower charger connector. The at least one lower charger connector is attached to the upper side of the horizontal lifting frame and is connected to the first rechargeable power supply.

A system for servicing a nuclear reactor module comprises a crane operable to attach to the nuclear reactor module, wherein the crane includes provisions for routing signals from one or more sensors of the nuclear reactor module to one or more sensor receivers.

A lifting fixture comprises a lifting affordance slidingly coupled to an upper horizontal beam assembly, a lower assembly comprising two spaced-apart horizontal beams defining an intervening gap, and a substantially vertical structural assembly connecting a first end of the upper beam assembly to a first end of the lower assembly. The horizontal beams include arrays of threaded holes for receiving various adapter plates. The first horizontal beam assembly comprises a motor driving a power threaded lead screw engaged to a lifting affordance such as a lifting eye. The motor may be controlled by wireless remote control. The lifting fixture allows lifting of an object stored beneath an overhead obstruction to be manipulated using a crane whose lifting axis is offset to the side of the overhead obstruction.

A crawler type crane having a base carrier unit having a control unit associated therewith and an upper portion assembly having a boom portion coupled at end to the base carrier unit and to a jib portion at an opposed end. The boom portion includes one or more selected boom sections that are articulatable relative to each other. The crane also includes a multi-function attachment unit that is coupled to the jib portion and has a grappling unit for grasping a work piece and a saw attachment unit for cutting the workpiece. The crane can also include a first fluid regulating device coupled to the jib portion for regulating a fluid to the jib portion and to the multi-function attachment unit and a second fluid regulating device coupled to the boom portion for regulating a fluid to the winch element and to the multi-function attachment unit.

The invention concerns an arrangement for the guidance of flexible lines that run from a crane arm (3) through its end section (2) to a tool (4), that is suspended at the crane arm through a link arrangement (5) and a frame that is a component of a rotator (6) for rotation around a vertical first axis (A) and in a cardan manner around second (B) and third (C) horizontal axes, For the discrete and protected passage of hoses, it comprises a first holder (35) in an opening (3A) of the end section (2), a second holder (38) in a central region of the rotator (6), a first hose package (1A-1D) that extends between the said first (35) and second holders (38), a penetration (26) in a central region of the rotator (6) and permitting hydraulic fluid to pass through the rotator (6) and onwards to a lower part (18) of the same at least one of the said second (B) and third (C) horizontal axes comprises an “open joint”.
