WalvoilALSsystem, the efficient management of lifters
Adaptive Load Sensing (ALS), awarded with the Technical Innovation at EIMA 20/21, is a system made up of a directional valve, an electronic joystick and an electronic control unit, with customizable software. This is a technology developed by Walvoil, (a Reggio Emilia – based company specialized in the industrial sector) in partenrship with Dieci, has the function to modulate the value of the "Stand-by margin" by automatically seeking the conditions of maximum efficiency. The hydraulic systems - explains the manufacturer with a technical note - are the real beating heart of modern agricultural machinery, in particular of telescopic handlers. To ensure the full operation of the vehicle, the hydraulic pumps generate a higher pressure level than what is actually required by the users: the preset value of the "Stand-by margin" facilitates control, but involves a loss of energy, weighing on the vehicle's fuel consumption, consequently increasing its environmental impact. Instead, as confirmed by the operational tests, the Adaptive Load Sensing enables a significant reduction in fuel consumption.
The tests - we read in the note issued by Walvoil - were carried out on the telescopic loader of the Agriplus series produced by the Dieci company of Montecchio Emilia (Reggio Emilia), and showed a 28% reduction of energy dissipation in the lifting phase and 45% in road transfers. In addition to the high customization possibilities, the manufacturer points out the other advantages of the ALS, such as the simplicity of installation of the kit that also renews the machines in service, bringing them to new levels of performance and cost-effectiveness.
