The HCX-3 Portable Mining Telephone is a rugged communication unit designed for underground and surface mining environments. It features an 800 Ω ±20 % telephone impedance and can maintain clear voice transmission over distances up to 21 km when ambient noise is below 75 dB. The device measures 222 mm × 195 mm × 107 mm and weighs approximately 2.5 kg, allowing it to be mounted on a rack or carried in a portable enclosure.
Its construction tolerates extreme conditions: operating temperatures from - 40 °C to +50 °C, pressure of 750 mm Hg ± 30 mm Hg, and relative humidity up to 98 %. All internal components are fixed to a solid frame, and the unit incorporates multiplexed lines to support multiple users simultaneously. Typical power is supplied by a 12 V DC battery, and the enclosure is commonly rated IP65 for dust and water protection.
The telephone is used by mining contractors, ventilation engineers and safety officers who require reliable voice contact in hazardous zones. Buyers usually request bulk quantities for site deployment and need to confirm minimum order quantities, lead times and shipping terms directly with the supplier. Payment and Incoterms are negotiated on a case‑by‑case basis, so importers should request a detailed quotation before placing an order.

Before ordering, importers should request the full technical data sheet, battery specifications and any available type‑test certificates to confirm that the telephone meets local safety regulations. Verify the supplier’s production capacity and ask for a sample unit if possible, as the listed response metrics suggest limited communication history on the platform.
Logistics for this equipment typically involve container or pallet shipment; however, the exact Incoterms, freight options and lead‑time are not disclosed. Ask the supplier to specify CIF or FOB terms, expected shipping duration from Yantai port, and acceptable payment methods such as T/T or L/C.
Upon receipt, conduct a functional inspection of impedance, battery voltage and enclosure sealing. Arrange for a third‑party audit if large volumes are planned, and request the original CE or equivalent conformity documents to ensure compliance with your market’s technical standards.
