Method for controlling height of work machines
A method for controlling a height of a work machine (100, Figure 1) is provided. The method includes:- i) determining an expansion or retraction event of a fluid cylinder 122; ii) moving a valve 210 to a first condition in response to the expansion or retraction event to disallow fluid communication...

Zusammenfassung: | A method for controlling a height of a work machine (100, Figure 1) is provided. The method includes:- i) determining an expansion or retraction event of a fluid cylinder 122; ii) moving a valve 210 to a first condition in response to the expansion or retraction event to disallow fluid communication between an accumulator 212 and an end chamber 170, 172 of the fluid cylinder 122; iii) receiving a pressure signal associated with a fluid pressure at the end chamber 170, 172 upon completion of the expansion or retraction event to cause a proportional pressure control valve 218 to move and equalize a fluid pressure of the accumulator 212 with the fluid pressure at the end chamber 170, 172 of the fluid cylinder 122; and iv) moving the valve 210 to a second condition pursuant to an equalization of the fluid pressure of the accumulator 212 with the fluid pressure at the end chamber 170, 172 of the fluid cylinder 122 to allow the fluid communication between the accumulator 212 and the end chamber 170, 172 of the fluid cylinder 122. |
