Patent ID: 7318292

Claim:
A method for attenuating the motion of a hydraulic cylinder ( 10 , 11 ) of mobile work machinery comprising the steps of: a) registering the speed of the hydraulic cylinder ( 10 , 11 ) prior to its reaching a respective limit of travel and determining whether the speed exceeds a predetermined value; b) reducing the speed of the hydraulic cylinder ( 10 , 11 ) if the speed exceeds the predetermined value prior to reaching one of the limits of travel of the hydraulic cylinder ( 10 , 11 ), and c) moving the hydraulic cylinder ( 10 , 11 ) to the respective limit of travel at reduced speed, wherein said step (c) of reducing the speed is accomplished by the steps of (i) throttling the inflow to, and/or the outflow from, the hydraulic cylinder ( 10 , 11 ) by a flow control device ( 4 , 5 , 6 ), and ii) changing the point in time (P 7 , P 7 ′) when throttling commences depending on the registered speed.
