The Mechanical Integrity of 50-Ton Hitches
For 50-ton class excavators like the Volvo EC480, structural integrity is paramount. While hydraulic hitches are convenient, our Manual Mechanical Coupler offers zero hydraulic failure risk in extreme mining conditions. Each coupler is manufactured from Q355B high-tensile steel, with all pivot points undergo High-Frequency Induction Hardening to HRC 45-50. This prevents the pin bores from ovaling under the 300+ kN breakout force of the EC480 boom.
Safety Tip for 48-Ton Operations: When using a manual screw-type coupler on a large excavator, always ensure the locking safety pin is fully engaged after tightening the main spindle. We recommend checking the spindle tension every 50 working hours. For high-impact demolition or quarrying, a manual coupler provides a more rigid connection, reducing wear on the original Volvo arm bushings.
