Overload protection for LEMKEN ploughs
Failure-free operation under any condition
All LEMKEN overload protection systems protect against damage when the plough point encounters an obstacle. Shear-bolt or auto-reset options are available. LEMKEN auto-reset systems use a roller mechanism which provides smooth tripping with high trip and re-entry forces when the plough makes contact with an obstacle. Plough and tractor are protected from shock loads.
- The mechanical tandem auto-reset with beams and legs made from spring steel provides large lateral tripping.
- The HydriX hydraulic auto-reset provides adjustment of trip force between 50 and 140 bar. Users can select a low trip force in light soil conditions so that stones remain in the soil. In heavy or hard conditions, high trip forces ensure the plough bodies resist the tough soil, only moving when they contact a large stone or similar obstacle.
- The Hydromatic auto-reset protection, with its firm connection of the plough bodies to the supporting point, allows horizontal and lateral movement at the same time. The protection element is completely maintenance-free.
