A victim retrieval apparatus for use with a vehicle. In some embodiments, the rescue basket comprises one or more wheels. The articulating head of the boom comprises a rotatable pulley for receiving the rescue line and is able to allow the vehicle to be parked in any position necessary while rescuing the victim. A knot-passing pulley enables a safety line (with emergency brake device) to be coupled to the basket thereby ensuring the safety of the victim in the basket at all times. The rescue basket comprises a remote control for controlling the winch speed that is able to be located at the winch itself, or be of a hand-held nature and attached at the rescue basket instead of at the vehicle if visual contact is problematic.

The shoe derailment device for use in derailing a conductor shoe assembly of a bridge crane from a conductor rail assembly generally has a wedge head provided at a longitudinal end of a body made of an electrically insulating material, the shoe derailment device being securable to the conductor rail assembly in a derailment position in which the shoe derailment device is positioned outside an operating zone of the bridge crane, with the wedge head facing the operating zone in a manner that if the conductor shoe assembly is moved outside the operating zone, into the area occupied by the shoe derailment device, the conductor shoe assembly is derailed from the conductor rail assembly as the conductor shoe assembly engages the wedge head and is maintained in a derailed state by the electrically insulating material when the conductor shoe assembly is engaged with the body.

The disclosure relates to a mobile crane, in particular an rough terrain crane, comprising a boom mounted so as to be pivotable about a horizontal pivot axis, a hydraulic luffing cylinder by means of which the boom can be luffed up and down about the pivot axis, a hydraulic control block for controlling the luffing cylinder and a first safety valve which is connected between the control block and the luffing cylinder and is configured to seal off a load-bearing cylinder chamber of the luffing cylinder in a blocking position. According to the disclosure, the crane further comprises a second safety valve, which is connected in series between the first safety valve and the control block and is configured to seal off the load-bearing cylinder chamber of the luffing cylinder in a blocking position.

Provided is a weight capable of being easily attached to and detached from a load suspended-load rope. The weight is disposed to detect overwinding of a load suspended-load rope suspended from a derricking member of a construction machine. The weight includes a weight body, which has a cylindrical shape enclosing the load suspended-load rope, configured to be suspended from the derricking member through a string-like part. The weight body is formed with a rope insertion space that allows the load suspended-load rope to pass through the rope insertion space in the radius direction of the suspended-load rope. The rope insertion space includes an oblique slit part, which has a shape oblique to the center axis.

A hoist lifting system having planning and monitoring of components. The system monitors one or more components and may have a processing structure and memory storing instructions to configure the processing structure to: receive hoist machine data; determine a rotation speed of a bearing, a travel speed of a rope, a load on the bearing, a friction in the at least one bearing based on the hoist machine data; and store the rotation speed, the travel speed, the load, and the friction in a maintenance database in memory. The hoist lifting system may have the processing structure determine a wear of one or more components.
