The heavy equipment operator on a forest jobsite is often part of a 2 to 10-person team engaged in logging, forestry maintenance, or road building. The “operator” runs a machine (heavy equipment), which is purpose-built to accomplish a specialized forest production task—such as tree falling, log processing, debris piling, or road grading. Each machine demands specific skills in operation and safe performance. The operator spends much of their day inside an enclosed climate-controlled machine cab, at the automated controls that direct the machine’s movements. The operator is typically responsible for their own machine basic service, refueling, diagnostics and minor repairs.
All operators in these highly-sought jobs receive ample job-tailored safety and task training, due to the demanding production and many hazards from machinery movements, falling trees, moving logs, rough terrain, earth movement, mechanization, and mountain driving. Becoming a proficient heavy equipment operator takes a tremendous amount of skill and experience, often learned by working your way up-the-ladder in related jobs and operating less complicated machinery. Inexperienced new employees must start in entry-level jobs to learn the trade. Then, once more experience is acquired, seasoned workers can learn equipment operation from an experienced operator.
Today’s forest management tasks involve modern mechanized processes, many which utilize heavy equipment tailored to safe & efficient production. There are machines designed to fall standing trees, other machines to cut (buck) and delimb them into desired log lengths, or other machines to move trees from the stump to the roadside landing—often on steep hills and over long distances. At the road, the many log types are processed, sorted and loaded on trucks for transport to different mills. An there are many more machines designed to maintain trees and roads, as well a construct the forest roads needed to manage the forest.
BACKHOE OPERATOR
Operates a “backhoe” machine, which is a tractor-sized, wheeled vehicle that works to dig dirt & rock for building or repairing forest road ditches and culverts—it’s equipped with a rear-mounted small bucket attached to a digging-boom arm, used for small excavating and trenching jobs.
CHIPPER OPERATOR
Operates an “in-woods chipper” or a “tub grinder” machine, which parks at a roadside landing to grind piles of forest waste-wood and tree debris—producing wood chips and biomass fuel* useable in a number of commercial products. The chipper machine grinds the woody material, and then dumps the ground-up wood into a waiting truck. The chipper operator runs a purpose-built, large portable machine, which is equipped to grind whole trees, limbs, chunks and woody logging debris (“slash”), thereby turning the wood into chips or hogg fuel*, to then be loaded onto semi-trucks or chip vans. The chipper machine can process smaller whole trees and logging slash in a single motion, while parked at a roadside “landing” area. Chippers can be equipped with additional features/attachments, such as a loading boom & grapple, debarker, chip screens, or chip conveyor. The operator safely controls the machine from within a cab using buttons, pedals and levers, on forest roads and log landing areas, to skillfully grind waste wood into usable wood chip products. Operator drives a company pickup to the forest job sites; and often works independently, following detailed work plans and specifications. Communicates safe machine and log movement activities using a radio. Operator may be responsible for machine basic service, refueling, diagnostics and minor repairs. Requires special safety gear, climbing off & onto the chipper, and some walking on sloping forest terrain.
