Heavy duty feeding chute

The chute liners on the S3 stacking conveyor are made of wear-resistant Hardox HB 450 for longer wear life and a reduced wear costs.

Steel hydraulic lines

Steel Hydraulic lines are used throughout the machine where possible. Offering many benefits including increased strength, improved safety, easier repairability and better heat distribution, these steel hydraulic lines improve the lifespan of the lubricants.

Fuel efficient

The S3 conveyor features load-sensing hydraulics which offers upwards to 20 – 30% in fuel savings compared to traditional diesel-driven drives. The system automatically detects where hydraulic power is needed in the machine and adjusts accordingly. Fuel savings are achieved by reducing load when it is not required.

Fully mobile

The S3 is a fully mobile stacking conveyor with independent power and tracking capabilities that allow for site maneuverability and quick setup times.
