12, 24, 48 and 80 V. In cases where the battery voltages are higher then 12 VDC, the system demands a DC-DC voltage converter with an output of 12 Vdc. Only by RAVAS approved convertors may be used. If other convertors are used the warranty of the indicator is no longer valid. -
Page 7: Before The Installation
The RAVAS-SafeLoad will operate optimally at an oil pressure up to 350 bar. 4.3. Battery voltage of the forklift truck The most common voltages for forklift trucks are 12, 24, 48 and 80 VDC. The RAVAS-SafeLoad operates on 12 Vdc and can handle voltage differences between 9VDC and 18VDC. In cases where the battery voltage is greater than 12 Vdc, the system requires a DC-DC power converter with an output voltage of 12 Vdc. -
Page 8: The Condition Of Mechanical Components Of The Forklift Truck
The condition of mechanical components of the forklift truck After installation of the RAVAS-SafeLoad system on the forklift truck, the truck is part of the system. In particular the mechanical parts of the forklift truck, such as the mast, mast roles and bearings, will influence the accuracy of the weightings. -
