Vehicles are disclosed for the internal transport of heavy-load coils. The vehicle may include a drive unit and a loading device coupled thereto. The loading device may be configured to hold a plurality of heavy-load coils. An articulated steering system may be formed between the drive unit and the loading device. The vehicle may include separating elements connected to the loading device, which may be movable parallel to a vehicle longitudinal direction. The separating elements may be configured to secure heavy-load coils of different widths against tilting.

A slew bearing includes a stationary bearing ring to be fixed to a base, and a moveable bearing ring to be fixed to a moveable object, wherein the stationary bearing ring and the moveable bearing ring are configured to enable rotation of the moveable bearing ring relative to the stationary bearing ring about a rotation axis. A main axial bearing and an auxiliary bearing are provided between the stationary bearing ring and the moveable bearing ring, wherein the moveable bearing ring includes one or more main portions and one or more auxiliary portions, which one or more main portions are moveable relative to the one or more auxiliary portions between an operational position, in which the main axial bearing transfers the axial loads between moveable bearing ring and stationary bearing ring, and a raised maintenance position, in which the auxiliary axial bearing transfers the axial loads between moveable bearing ring and stationary bearing ring and the main bearing is allowed to be inspected and/or maintained so that the slew bearing during inspection and/or maintenance is still operational.

A crane support system includes two spaced apart longitudinal members couplable with a vehicle frame. Two spaced apart groups of tubes are coupled with and extend between the longitudinal members and outboard relative to one member to define an outboard subassembly portion. A tower frame is mounted atop the outboard subassembly portion. A first brace extends angularly between the groups of tubes, the brace extending from a one of the groups forward relative to the vehicle frame toward the other group aft relative to the vehicle frame and toward the tower frame. A horizontal arm extends transversely beneath the outboard subassembly portion. A vertical support has a top end coupled with the arm and a bottom end couplable with an outrigger. A second brace extends angularly between the vertical support and the arm for transferring bending moment and/or shear from the cantilever to the outrigger via the vertical support.

A holding device for use with a telescopically extensible crane boom (57) in order to keep a load handling tool (4) in a given parking position in relation to the crane boom. The holding device (1) comprises: an attachment (10) to be fixed to an end of a telescopic crane boom section of the crane boom; a tool holder (15), which is detachably mountable to the attachment (10) and configured for engagement with the tool in order to support it against the crane boom and keep it in the parking position, the tool holder being provided with a sliding member (28), through which the tool holder is configured to slidably rest against an external surface on the crane boom; and a locking mechanism (16) for locking the tool holder and the attachment to each other when the tool holder is mounted to the attachment.

This invention relates to a crane comprising an undercarriage and a turntable rotatable with respect to the undercarriage with a counterweight and a mounting point for the attachment of a winch, wherein the counterweight includes at least one winch pick-up means for the temporary attachment of a winch to be mounted on the turntable, wherein the winch can be attached to the winch pick-up means such that the winch can be pivoted about a vertical axis.

A boom attach/detach device includes a boom, an extensible cylinder, and a boom supporting device. At least a part of the boom supporting device is arranged more to a boom front end side than an upper slewing body. When the extensible cylinder conducts extension and contraction operation in a state where coupling between the upper slewing body and the boom by a boom foot pin is cut off, the boom supporting device supports the boom to enable a rear end portion of the boom to move in a boom axis direction. The boom can be attached or detached with ease without a need to use a separate power device from a crane to suppress increases in size, in mass, and in cost of an upper slewing body.
