An Enhanced Lift Assist Device is described. The device allows a user to lift and manipulate large, heavy or bulky items by applying force to the item as opposed to traditional control methods such as buttons. This force based system provides ease of movement of the item, making it appear much lighter than it actually is. The Enhanced Lift Assist Device also includes an adjustable base that allows for change of orientation of the device that may include leveling or self-leveling functionality, allowing the device to be operated in non-traditional environments that require leveling or operational adjustments for proper functioning.

The invention relates to a mobile crane with a two-part jib and to a method for aligning the boom system of such a mobile crane. The invention relates to a mobile crane with a multi-part flight boom, wherein a first jib part is hinged to the main boom in a rockable manner, and at least one second jib part is secured to the first jib part in an articulated manner. A bracing which is guided from the upper chassis to the jib is provided for aligning the jib, said bracing running over at least one intermediate bracing support mounted on the first jib part to the at least one second jib part.

There is provided a crane including a main body, a tower derrickably supported by the main body, a jib derrickably supported by the tower, an assist member that assist the jib to move along a ground, and a determination unit that determines whether or not the jib is stopped when the tower is lowered in a lowering work state where the jib is assisted by the assist member.

A hoisting crane or multi configurations crane system for use on an offshore vessel, such a vessel and methods for operating are disclosed. The hoisting crane comprises a boom having a proximal portion, an intermediate portion and a distal portion. An extension mechanism is provided that is configured to allow the distal portion to he slid relative to the intermediate portion from a retracted configuration to an extended configuration. In the retracted configuration, the intermediate portion is arranged substantially within the distal portion.

A vehicle crane, such as a mobile crane, includes a main jib and a main jib extension that is mounted thereon and can be luffed by at least one luffing cable. The vehicle crane includes at least one anchoring support that is arranged on the main jib and guides the luffing cable in order to anchor the main jib to provided improved load-bearing capacity.

A mobile crane comprising a telescopic boom which has a main casing with linearly moveable inner casings. Guying equipment can be added to the telescopic boom, where at least one securing region arranged on the main casing is provided for the fixing of the guying equipment. In order for the adding and removal of the guying equipment to and from from mobile crane to be carried out more easily and safely, at least one coupling region is arranged on one of the inner casings for adding and/or removing the guying equipment and which can be connected to the same. In this way, the guying equipment can be received directly from a transport unit by the at least partially extended telescopic boom, the guying equipment can be moved onto the main casing by retracting the telescopic boom and coupled to the same.
