A crane system, a crane, and a mobile unit capable of easily coping with a case where electrical equipment such as an obstacle light fails are to be provided. A crane system includes a crane body and a mobile unit movable around the crane body. The mobile unit includes an obstacle light and functions as an obstacle light for the crane body.

A boom system including a hoist boom pivoted to a machine base; a stick boom having a proximal end pivoted to the hoist boom and a distal end configured to carry a working tool; at least one hydraulic hoist cylinder mounted between the machine base and the hoist boom; a first stick cylinder mounted between the hoist boom and the stick boom; a second stick cylinder mounted similarly and mechanically linked with the first stick cylinder; and a hydraulic circuit for supplying hydraulic fluid to the hoist cylinder and stick cylinders, wherein the hydraulic circuit includes a hydraulic conduit line connecting a base end of the at least one hoist cylinder with a base end of the second stick cylinder to allow hydraulic fluid to shunt between the base ends of the hoist cylinder and the second stick cylinder.

Embodiments of a vacuum material handler or lifting device and system of this disclosure provide a modular design that allows a power pack to be mounted directly to the pad or remotely mounted on host equipment to minimize lift weight. The pad, which includes an integral, pad reservoir, may be arranged, to accept a rotator or a tilting mechanism for position when used on mobile equipment. The power pack is independent of the pad and can be transferred to multiple pads, thereby permitting a single power pack to service the different pads. The control mechanism may reside on the pad to further facilitate modularity. Safety checks used for remote operation may be used to minimize the risk of danger in the event of remote vacuum hose or vacuum failure.

A spreader for lifting an intermodal transport container includes a main beam extending in a longitudinal direction, the main beam formed of a first, upper C-beam of a relatively thicker material thickness and a second, lower C-beam of a relatively thinner material thickness; and an indicator configured to provide an indication if a distance in a transversal direction between a pair of twist-locks is set in a wide-body position when lowered onto respective lifting castings provided with top openings separated by a transversal distance corresponding to a standard position.

A connecting arrangement by which an electric load, which can be displaced in at least one direction of travel in relation to a feeder device, is supplied, by a cable, with electrical energy and/or data. The feeder device has at least one connection member for connecting to a corresponding connecting element of a cable carried by the electric load. An energy-supply system supplies the electric load. A simplified automatic connection of the cable to the feeder device by a connecting arrangement has a manipulator for connecting the connecting element to the connection member. A related energy-supply system has such a connecting arrangement and a related method has the following steps: a) positioning the connecting element in relation to the feeder device, b) using a manipulator to grip the connecting element and/or the cable, and c) using the manipulator to connect the connecting element to the connection member.
