A lifting and transporting device for lifting a load and transporting the same transversely to the lifting direction. The lifting and transporting device being for use in manufacturing a screwed flange connection. The lifting and transporting device having a frame for picking up and lifting a load, a holder for holding the load and comprising a hoist for lifting and lowering the holder with the load attached thereto, includes a tensile anchor which is operatively connected with the bolting tool and in a state of the lifting and transporting device mounted on a flange can releasably be connected with the flange or with at least one screw bolt connection and is designed to limit the lift-off path of the bolting tool in the hoisting direction to a specified amount in the case of a fracture of the screw bolt connection to be pretensioned or of the connection of the bolting tool with the screw bolt connection to be pretensioned during the pretensioning of this screw bolt connection.

A crane, particularly a rubber-wheel container crane includes a frame which has, on opposite sides of its lower part, main beam structures at both ends of which, i.e. in the lower corners of the crane, there are two successive rubber wheels or wheel arrangements through which the crane is supported by its moving carrier. These wheels are supported by the main beam structure rigidly and in an unsuspended manner.

The invention relates to container carriers that are used in ports and terminals. The invention comprises a method, an apparatus and a computer program product for moving a container carrier. The method comprises the steps of lowering the container, causing to disengage the weight of the container and the spreader off the wheels, tuning the wheels to an orientation suitable for a carousel or skew maneuver, lifting the container and starting a carousel or skew maneuver.

A continuous container crane device may include a first track having a continuous shape and a second track having a continuous shape. Preferably, the first track may be substantially parallel to the second track. One or more trolleys may be movably coupled to the first track and to the second track so that the trolleys are configured to move in a continuous movement path (starts and finishes at the same place) defined by the first and second track. Each trolley may include a lifting mechanism that may be coupled to a container spreader which may be removably coupled to shipping containers for the transport of shipping containers to and from trucks with a chassis trailer, all types of intermodal railroad flat cars, ships and other water traveling vessels, container storage lots, etc.

A substrate transfer device includes a housing accommodating a carrier for storing a substrate, a carrier lifter moving the carrier in a vertical direction relative to an upper surface of the housing, a vertical stabilization unit connected to a lower part of the carrier lifter and reducing a vertical vibration of the carrier, a rotation stabilization unit connected to a lower part of the vertical stabilization unit and reducing rotation of the carrier, and a carrier holder connected to a lower part of the rotation stabilization unit. The carrier holder holds the carrier. The vertical stabilization unit includes an upper plate connected to the carrier lifter, a lower plate connected to the rotation stabilization unit, and a buffer disposed between the upper plate and the lower plate. The buffer contracts or relaxes to reduce the vertical vibration of the carrier.
