A rail-guided permanent way machine is operated by means of a control device in such a way that at least one state variable (Z) of the permanent way machine is determined in dependence on an operating state, and the at least one state variable is compared to at least one pre-defined limit value (G.sub.W, G.sub.S) for monitoring a derailment safety of the permanent way machine. Thus, the derailment safety of the permanent way machine is determined in accordance with the current operating state and monitored. As a result, the permanent way machine has an expanded operating range and increased performance and thus increased efficiency.

A crane includes a jib which is mounted on the crane structure so as to be rotatable about a bearing point, a counterweight arrangement which can be positioned variably in relation to the bearing point, and a hoisting cable which runs out from a hoisting winch and is guided via the jib. A counterweight adjustment device, which is coupled to the counterweight arrangement, includes a lever element mounted rotatably about a pivot point, a hoisting cable guide arranged in the course of the hoisting cable between the hoisting winch and an upper jib section, with a first deflecting pulley arrangement mounted on the jib and a second deflecting pulley arrangement mounted on the lever element, wherein the hoisting cable is guided in an alternating manner via the first and the second deflecting pulley arrangement, and a coupling element acting on the lever element and connected to the counterweight arrangement.

A container handling vehicle picks up storage containers from a three-dimensional grid of an underlying storage system. The container handling vehicle includes a vehicle module part (P1); and a container lifting part. The vehicle module part (P1) includes a first set of wheels for moving the container handling vehicle in a first direction (X) and a second set of wheels for moving the container handling vehicle in a second direction (Y). The second direction is perpendicular to the first direction. The container lifting part extends sideways as a cantilever from the vehicle module part (P1) and includes a hoist frame (P2) with an opening (OSP) defining an access perimeter; a hoist mechanism carried by the hoist frame (P2); a plurality of lifting bands connected to the hoist mechanism and guided by the hoist frame (P2); and a lifting frame for releasable connection to a storage container, the lifting frame being suspended in a horizontal orientation from the hoist frame (P2) by the plurality of lifting bands. The lifting frame has an opening (OLF) defining an access perimeter. The access perimeter of the opening (OSP) in the hoist frame (P2) corresponds in shape and alignment to the access perimeter of the opening (OLF) in the lifting frame to allow access to items in the storage container through the respective openings (OSP, OLF) when the lifting frame has been lifted up to the hoist frame (P2) by the hoist mechanism.

The invention relates to a method for unloading, transporting and installing a railway track, which does not require the rail-carrying train to be brought closer after each cycle of unloading continuous welded rail (CWR), the train remaining parked at the end of the track already laid until all the CWR has been completely unloaded. According to the invention, the method consists of: fastening two rails to a crane of an unloading wagon and moving same through windows along the wagon, facilitating the descent thereof to the track; transferring the rails to a machine for pulling and positioning which moves along, leaving the rails supported on transport elements that move along the track already laid; transferring the rails from the track already laid to a section of sleepers; and moving the rails to their final position, using sliding elements placed on the sleepers.

A longitudinal beam of a track maintenance vehicle is connected at a beam exterior side—facing away from the opposite longitudinal beam—to a rail transport device provided for receiving rails. The rail transport device is displaceable by means of a displacement drive in the transverse direction of the machine relative to a machine frame within a displacement path s delimited by a transport—and a loading position.
