RAVAS introduces RCS Hy-Q, a high accuracy hydraulic scale for counterbalanced trucks and reach trucks. On a 2.5T lift truck the RCS Hy-Q shows the weight on the forks in 2 kg increments. Next to the weight, the display in the lift truck cabin also shows a load bar that indicates how much of the lifting capacity of the truck is used. Green means safe, yellow means close to 100% lifting capacity, red means overload.
Its unique features make the RCS Hy-Q insensitive to changing load center positions, ideal for use in combination with (paper)roll clamps and side shifters. The RCS Hy-Q does not require a manifold block or return line to the hydraulic tank of the truck, making it easy to install and safe to use: an uncommanded descent of the forks because of a stuck valve is not possible.
Weighing up and down for maximum accuracy
The weighing is done UP and DOWN: the load is lifted, and then lowered past two sensors on the mast within a predefined speed bandwidth. Weighing UP and DOWN averages out influences from asymmetrical friction in the mast, as may happen with eccentric load center points. Weighing UP and DOWN makes RCS Hy-Q more accurate and suitable for use in combination with (paper)roll clamps and side shifters or fork positioners.
Full color driver display to guide the user
The RCS Hy-Q has a dedicated, full color graphic display. The upper half of the display shows the weight in a blue field, if the load has been lifted and lowered with the proper speed, for best accuracy. If the load was lifted or lowered too fast or too slow, this field is red. The actual lifting / lowering speed is shown in cm / sec in the bottom right corner of the display. In the center of the display there is a load bar: it shows how much of the lifting capacity of the truck is used. Green means safe, yellow means close to 100% lifting capacity, red means overload.
No valve block: cost efficient and safe
The RCS Hy-Q does not require a manifold block or return line to the hydraulic tank of the truck, but only uses a pressure sensor that is installed on a hydraulic lead via a T-piece, as with the RCS. This makes the installation of the RCS Hy-Q easy and cost efficient. It also makes the system safer to use: an uncommanded descent of the forks because of a stuck valve is not possible.
