A safety device for a mobile crane has: a permitted work range setting unit that, in accordance with whether or not the overhang angle of each outrigger is a reference overhang angle and the overhang length is the maximum overhang length, sets the permitted work range/non-permitted work range of a crane boom; and a load-specific work range setting unit that, in accordance with whether or not each of the outriggers overhang lengths is a maximum overhang length, sets a maximum RTL work range which is a range, within the permitted work range, in which crane work at a maximum rated total load can be carried out. The crane work capacity on the side of the outrigger having the maximum hangover length with high supporting capacity can be fully utilized within a range over which safety can be ensured.

A work machine includes a base, a mount coupled to the base, wherein the mount is configured to support an arm. The arm is pivotally coupled to the mount, and includes a boom and an engagement mechanism positioned at the head of the boom. The mount is configured to raise and lower the arm relative the base. The engagement mechanism may include an extendable grabber to interface with one or more objects and lift and position the objects using the mule. The work machine may include a leveling system coupled to the base. The leveling system is configured to stabilize the base in an approximately level position, and includes a plurality of outriggers positionable between a stowed position and a deployed position. A first total width of the work machine in the deployed position is greater than a second total width of the work machine in the stowed position.

A rough terrain crane is equipped with dashboard cameras and digital cameras for capturing bird's-eye view image thereof. The equipment performs, when a load factor reaching 90%, a process of recording start for starting image data recording with the digital camera and a process of storing measurement value for recording a load factor concurrently with the process of recording start. The image data is recorded with the digital camera associated with the above activation condition, among the digital cameras installed in the rough terrain crane.

The present invention relates to a support structure for a vehicle provided with a cargo crane having a crane base, said support structure comprising a support beam connectable to said crane base and a support leg, wherein a proximal end of said support leg is connected to said support beam at a pivoting point, such that, said support leg is pivotable around said pivoting point relative to said support beam. The support structure further comprises an actuating device connected to the support leg for pivoting said support leg relative to said support beam, wherein said actuating device is configured to arrange said support structure in at least a tunnel mode and a diagonal mode, by adjusting an extension of said actuating device, such that in the tunnel mode, a distal end of said support leg is positioned to abut against a supporting surface on which the vehicle stands and in the diagonal mode, a knee of the support structure or at least a part of a lateral side of said support leg is positioned to abut against the supporting surface on which the vehicle stands.

A device monitors for bearing capacity failure of a mobile work machine. The work machine has a number of stabilisers. Each stabiliser has a support foot having a support foot plate. When the mobile work machine is in a supported state, the support foot plate of at least one support foot is arranged on a base surface surrounding the work machine or on a base plate. The device for bearing capacity failure monitoring has a number of sensors for sensing a change in position of at least one support foot plate and/or at least one base plate. The device has an evaluation unit, which has a data connection to the number of sensors and is designed to detect a bearing capacity failure on the basis of a change in position of the at least one support foot plate and/or the at least one base plate that has been sensed by means of the number of sensors.
