Bosch Rexroth has also applied the LIFD control concept using conventional load sensing valves (non-LIFD controls) and electronics.
For example, Rexroth has a full line of LIFD control valves for general applications as well as control valves tailored to specific machine applications.
Overall, the advantages of LIFD control include easier operation, as the operator no longer must compensate for changing load or flow conditions, and this improved control allows faster working cycles with the same pump size and predictable movement of the machine at ally engine speed.
Controls of directional valves, like the Rexroth SX, M6 and M7 series, operate according to the LIFD principle, allowing fast and precise operations with simultaneous movements of several actuators at different load pressures.
The Gradall Co., headquartered in New Philadelphia, Ohio, was one of the first to introduce LIFD technology into its XL Series of hydraulic excavators.
The LIFD or flow control concept of the Gradall XL series allows operation of the hydraulic drive of the entire machine with only one main pump in the single-circuit system.
