Problems solved by technology

Due to the need for pick-up and handling cranes to travel with the load, this means that outriggers often cannot be used

Embodiment Construction

[0093] figure 1 , figure 2 and image 3 The pick and carry crane 10 is shown. The crane 10 has a front body 12 which is the front portion of the crane 10 . Front body 12 is pivotally arranged 30 (at figure 2 and 3 ) is pivotally connected to the rear body 14 of the crane 10 . The pivot point 30 is provided with a movable linkage (in this case a hydraulic link, but other linkages are also known) to control the pivot angle of the front body 12 relative to the rear body 14 . Adjusting the pivot angle using a movable linkage assists in turning the crane 10 .

[0094] When the front body 12 is pivoted relative to the rear body 14, a roll line 34 is defined (see Figure 4 ).

[0095] In the illustrated embodiment of the pick and carry crane 10, the roll line 34 is an imaginary longitudinal axis that passes at the point where the outer tire T1 of the front body passes through the wheel 20 to the ground and the outer tire T3 of the rear body passes through The points at whi...

Abstract

A method and corresponding system for controlling the operation of a mobile crane, the operation comprising a user input comprising a command to change the configuration of the mobile crane, the method comprising the steps of: determining a current tipping moment of the mobile crane, the tipping moment comprises a moment around a tipping line of the mobile crane; predicting the effect of the user input on the tipping moment of the mobile crane; and altering the response to the user input if the predicted impact of the user input is increasing the tipping moment of the mobile crane by more than a predetermined amount. Another aspect relates to a user interface for displaying to a user an effect of a user input on a tipping moment of a mobile crane, the user interface displaying a safe range of the effect of the user input and a non-safe range of the effect of the user input, which may lead to a tipping of the mobile crane.

Description

technical field [0001] Embodiments relate to controlling the operation of mobile cranes, particularly pick and carry cranes. Background technique [0002] A pick and carry crane is a crane that can move (ie travel) while having a load suspended on the boom of the crane. Some pick and carry cranes are capable of traveling on public roads at highway speeds, where they are classified as special purpose vehicles. Pick and carry crane designs can vary depending on the crane application. Some pick and carry cranes are designed for greater operational flexibility than other crane types. For example, when the pick and carry crane is articulated, the entire crane can fit within the crane's slew circle. This design feature may enable the use of an articulated pick and carry crane in tight or confined spaces to lift and move loads, such as loads on the floor of a manufacturing facility. [0003] Pick and carry cranes can also take the form of "taxi cranes", ie the crane travels wit...
