Bonfig Inline Gearbox-Rebuilt

Bonfig Inline Gearbox-Rebuilt

This is a rebuilt Bonfiglioli 580L planetary gearbox, a critical component for rotating the drum on large-capacity concrete mixer trucks. As part of Bonfiglioli's renowned 500 series, this drive is engineered for reliability and durability in the demanding conditions of concrete transport. A rebuilt gearbox provides a cost-effective solution for replacing a failed or worn-out unit, restoring the mixer's functionality and ensuring consistent drum rotation for proper concrete mixing during transit. The 580L model is specifically designed for trucks with a drum capacity ranging from 10 to 12 or 14 cubic meters.

Key Features

• Planetary gear design for high torque and reliability in severe duty cycles.
• Robust main bearing designed to support heavy dynamic loads from the drum.
• Spheroidal cast iron housing for high mechanical resistance to vibration and impacts.
• Designed for mixer drum capacities of 10-12 cubic meters.
• Tilting output flange to compensate for chassis flex during travel.
