A practical evidence checklist for RFQ preparation and supplier evaluation.
CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
The vacuum pad uses suction to adhere to the segment's smooth surface, while the mechanical claw uses hydraulic or electric actuators to clamp onto lifting points or edges. The choice depends on segment surface conditions and available lifting features.
The gripping force range is 5–50 kN, and the operating pressure is 0.6–0.8 MPa. These are directory reference ranges; actual values must be confirmed for the specific model and application.
The operating temperature range is -20 to 60 °C, and the ingress protection rating is IP65–IP67 (per IEC 60529). This protects against dust and water jets, but verify with the manufacturer for your specific environment.
It is controlled via the erector's central hydraulic and electronic systems, which provide force feedback, positioning, and release commands. The supply voltage is 24 V DC ±10%, and power consumption is 50–200 W.
