A system and method for controlling a grapple is described in embodiments herein. A variable pressure control may be implemented that controls the pressure applied to a load held by the grapple. An interlock mechanism may be employed on the felling grapple that disables the operation of components of the felling grapple such as a feller. A grapple release mechanism may be activated to release the pressure applied to the load in the event of a malfunction in the felling grapple.

The invention relates to a control method for controlling an actuating device in a handling machine, comprising: comparing (24) a magnitude representative of the movement speed executed or to be executed in response to a movement request signal to a threshold representative of a maximum authorised speed and controlling an actuating device according to the result of said comparison, so as to: execute or sustain (25) the movement of a handling arm as long as the magnitude representative of the speed of the movement executed or to be executed is less than said threshold, and prevent or stop (26) the movement of the handling arm as soon as the magnitude representative of the speed of movement executed or to be executed is greater than said threshold.

A boom extension monitoring system is provided that uses a combination of sensors to determine an absolute location and a relative location of the boom. As the boom extends or retracts, the monitoring system can determine the absolute location of the boom as the sum of the absolute at relative distances. These distances can be obtained through a combination of a grid, low-resolution sensors, high-resolution sensors, counters, processors, and other components according to various embodiments described herein. A process to obtain the total boom extension of multiple telescoping beams by monitoring the extension of a single beam element is also described.

The present invention relates to a crane having a boom at which at least one load receiving means is arranged in a raisable and lowerable manner, wherein an overload protection device has detection means for detecting the outreach and the load on the at least one load receiving means, and wherein a monitoring device for monitoring the overload protection device is provided and has determination means for determining a tensioning force holding the boom and/or induced in a guy cable. The invention furthermore also relates to a method for monitoring the overload protection device of such a crane. Provision is made in accordance with the invention that the monitoring device determines online in crane operation a tensioning torque from the continuously determined tensioning force, determines a lifting torque from the continuously detected outreach and the continuously detected load, determines a dead torque while making use of stored crane data, compares the sum of the named lifting torque and the named dead torque with the named tensioning torque and then, if a difference found in the comparison exceeds a tolerance threshold, emits an error signal and/or shutdown signal.

One variation of a method for monitoring lift events at a construction site includes: deriving a lifting profile from a first timeseries of load values, output by a load sensor coupled to a crane hook, during a first time period; deriving an oscillation characteristic from a first timeseries of motion values, output by a motion sensor coupled to the crane hook, during the first time period; identifying a type of an object carried by the crane hook during the first time period based on the lifting profile and the oscillation characteristic; selecting a load handling specification for the object based on the type of the object; accessing a second timeseries of motion values output by the motion sensor during a second time period; and, in response to the second timeseries of motion values deviating from the load handling specification, activating an object motion alarm for the object.

A method for determining stability of a vehicle having a load suspended from the vehicle is provided. The method can include obtaining measurements from a plurality of sensors positioned on the vehicle, obtaining a measurement from a vehicle accelerometer operative to determine an inclination of the vehicle, determining a position of the load suspended from the vehicle, determining a slung load of the load suspended from the vehicle, using the determined slung load and the determined position of the load suspended from the vehicle, determining tipping moments acting on the vehicle, determining righting moments acting on the vehicle and determining a tipping stability based on the determined tipping moments and determined righting moments.
