Company Name: 
Galena Contractors Ltd.
Details of Incident / Close Call: 

A Feller / Buncher operator was injured while installing a repacked radiator guard placement hydraulic cylinder into a Tigercat Feller / Buncher (Model L870). The operator was fastening the cylinder mounting bracket bolts / nuts on each end of the mounting brackets that keep the hydraulic cylinder in place, and he was using a jackall to align the hydraulic cylinder mounting assembly with the cylinder mounting brackets so that he could attach the bolts / nuts to keep the assembly in place.

The Feller / Buncher operator had previously lifted the radiator guard into place with the jackall, attached the bolts / nuts to stabilize the hydraulic cylinder, and had readied to lower the jackall lifting mechanism by releasing the reversing catch on the jackal.

At some point during the lowering of the jackall lifting mechanism, the jackall unleashed its support and a part of the jackall struck The Feller / Buncher Operator in the head, rendering him unconscious. The Feller / Buncher Operator was airlifted to a hospital where he was treated for his injury.

The Feller / Buncher Operator stated during an interview following the incident that he did not recall the point at which the support mechanism failed. He stated that he thought that he had barely touched (not applied direct pressure to) the reversing catch when the support mechanism failed (see photos in attached pdf).
