The tail plug is the core force-transmitting component that connects the power output end of the rock drilling rig with the drill pipe. It is a heavy-duty and shock-resistant accessory, mainly suitable for rock drilling equipment used for blast furnace iron outlet drilling, furnace body repair and crushing. Its structure and performance meet the strict working conditions of high-temperature and high-vibration.
Key Characteristics:
• High force transmission efficiency (Energy loss ≤ 8%)
• Shock and fatigue resistance (Withstands 1000-3000 impacts/minute)
• High temperature resistance (Works in 300-500℃ environments)
• Enhanced wear resistance (30%-50% longer service life)
High strength bearing: Using solid wood or plywood as the core material, it can withstand a load of 0.5-50t per box. It is fully compatible with heavy equipment such as rock drills and hydraulic mud cannons.
Comprehensive protection: Excellent resistance to impact and compression. Interiors can be customized with foam, rubber, and moisture-proof layers to protect precision parts.
Compliance standard: Fumigation/heat treatment solid wood or non-fumigation plywood is used, providing formal IPPC marks to meet international shipping and export requirements.
