Description: High-speed chains or rotating disks are commonly used to cut and process trees during forest harvesting operations. Mechanical failure or fatigue of these tools can lead to a potentially hazardous situation where fragments of chain or sawteeth are thrown through the operator enclosures on forest machines. This poster presentation discusses the development and validation of a facility to conduct thrown object tests for windows and doors used in operator protecttive structures on forest machines. The testing facility consists of a highpressure pneumatic laUOch system that propels sawteeth and chain fragments at velocities in excess of 150 m/ s.
Keywords: Operator Protective Structure, thrown object, forest machine
