The present invention addresses the problem of providing a crane and an information-sharing system with which it is possible to: display information pertaining to an entire range of operations, including a range of operations outside of an imaging region of a camera; and share, between a plurality of operators, information input in the entire range of operations. The present invention is equipped with a control apparatus (20), a display apparatus (crane-side display terminal (58)/display terminal (59)), and a sensor (GNSS receiver (53)) that acquires the coordinates of a camera (51), the control apparatus (20) acquiring map information M within the range of operations of a crane (1), and being capable of displaying the map information M on the display apparatus ((58)/(59)) and displaying, at a position on the map information M corresponding to the coordinates of the camera (51), an image I captured by the camera (51).

There is provided a crane that is assemblable and disassemblable and is capable of changing a monitoring range for periphery monitoring according to an assembly state of the crane.

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 telescoping boom includes a boom actuator having a fixed part and a movable part, the movable part configured to move along a length the fixed part, a rotary actuator operably connected to the movable part and configured to rotate relative to the movable part, a coupling pin connected to and configured to rotate with the rotary actuator, and a telescoping boom having a plurality of boom sections including a base section and one or more telescoping sections configured for telescoping movement along a longitudinal boom axis relative to the base section. A rotary extension and locking system is mounted on at least one telescoping section and is configured for selective coupling to the boom actuator and selective locking with a nearest outwardly adjacent boom section.

A mobile crane includes: a lower traveling body including a pair of crawlers; an upper slewing body supported on the lower traveling body slewably about a slewing axis; a tiltable attachment including a boom tiltably supported on the upper slewing body; and a physical quantity detector. The lower traveling body has a reaction force receiving part for receiving a reaction force from the ground at a position away from the slewing axis in a boom direction in a state where the pair of crawlers are in contact with the ground, the boom direction coinciding with a horizontal component of a direction in which the boom extends from the upper slewing body, and the physical quantity detector detects a physical quantity which changes in accordance with a change in the reaction force received from the ground by the reaction force receiving part.

A crane includes a carrier unit having a chassis, tires connected to the chassis, a carrier deck and outriggers. A superstructure is mounted on the carrier unit, the superstructure includes a telescoping boom. A slope sensor is operably connected to the carrier unit and configured to detect a pitch and/or a roll of the carrier unit during a lift operation. The crane further includes a system for monitoring a load lifted by the telescoping boom. The system is configured to determine the current load lifted by the telescoping boom, receive pitch and/or roll information of the carrier unit from the slope sensor, adjust coordinates of the crane in a coordinate system based on the pitch and/or roll information, determine a transformed operating radius using the adjusted coordinates; and compare the load lifted to a rated capacity at the transformed operating radius.

A crawler crane includes: a seating switch that detects whether an operator is in a driver seat; a turn angle potentiometer that detects the turn position of a boom; and a controller. The controller is provided with a boom turn restriction control unit for performing a boom turn-restricting control whereby the boom is not allowed to turn within a predetermined angular range above the driver seat on the basis of the output from the turn angle potentiometer. The boom turn restriction control unit includes a restriction-canceling unit that cancels the boom turn-restricting control performed by a turn-restricting unit if a preset restriction-canceling condition is met. The boom turn restriction control unit cancels the boom turn-restricting control if the seating switch does not detect an operator. Ease of operation and work can thus be improved in a remote operation mode and the like.

A height adjustment assistance device includes an initial state determination part for determining whether a suspended cargo has been lifted from a ground at a start of lifting work, a height detection part for detecting a height of a counterweight from the ground, a storage part for storing an initial height, a calculation part for calculating a target value for correcting the height of the counterweight from the ground based on the initial height and a post-work height, a notification part for notifying an operator of information regarding the target value, and a length adjustment device for adjusting a length of a hanging member by operating in a manner to change the length of the hanging member extending from a tip of a mast to the counterweight.

There is provided a crane for enabling easily carrying out an operation of a boom such as raising and lowering, telescoping, or turning, by displaying a range wherein a hook may be moved or may not be moved in a direction approaching a vehicle part of the crane. The crane includes: a vehicle; a boom positioned upon the vehicle; a wire rope being suspended from a base end side of the boom toward a leading end side thereof; a hook being hung from the leading end side of the boom and raised and lowered by winding and unwinding the wire rope; a camera for photographing an image including the hook; a display device for displaying the image; and a control device connected to the camera and the display device, the control device being for processing information. On the basis of the length of the boom or the height of the hook, the control device computes an inner boundary which is a boundary between a range where the hook may move, and a range where the hook may not move, in a direction approaching the vehicle. The display device displays an image wherein images indicating the inner boundary are superimposed on the image photographed with the camera.

An elongated pull element (14), in particular for an element of an expandable heavy equipment (1) comprises a bundle of load bearing fibers/fibres (41) extending along the length of the elongated pull element (14), and stiffening means (54) comprising an exoskeleton for increasing the bending stiffness of the elongated pull element (14), compared to the bending stiffness of the load bearing fibers/fibres (41).
