Hydraulic Hoof Trimming Machine

Overview

A safe, portable hydraulic trimming machine for cattle between 800 and 1200 kg. Thirteen hydraulic actuators drive the machine lift, leg lifts and gates, on a stainless frame that had to stay light without losing stiffness under eccentric animal loads.

Frames, mechanisms and hydraulics — designed, analysed and taken to fabrication.
