The unique design principle, combined with the installation kits, counterbalances movements caused by mechanical or thermal expansion or contraction of the construction. The unique combination of the selected geometry and material/surface hardness parameters guarantees perfect rolling characteristics, high restoring forces and long-term maintenance-free operation. A particular design characteristic is that the height and shape of the load cell remain constant over various load stages, whilst there is a particularly high overload range of, in part, up to 200%. 特性 20t… 75t, Typ C3/C4/C5/C6 1. No corner adjustment necessary 2. High overload capacity 3. IP 68 (1.5 m/10.000 hrs) IP 69K (washdown cleaning) 4. Proven rocker-pin principle 5. Best overvoltage protection 6. Highest reliability 7. 100 % Maintenance free 8. Ex - version available 9.
