With over 35 years of experience, our skilled technicians ensure your forestry machinery, from harvesters to skidders, operates at peak efficiency.

Common Equipment We Work On

CHIPPERS

Chippers utilize gear motors, vane motors, and piston motors to power feed rollers and cutting mechanisms, ensuring efficient wood debris processing.

EXCAVATORS

Excavators are equipped with gear pumps, vane pumps, and axial piston pumps that control the boom, arm, and bucket movements, providing precise digging and material handling.

FELLER BUNCHERS

Feller bunchers use radial piston motors, gear pumps, and proportional valves to operate the cutting head, efficiently felling and gathering trees.

FORWARDERS

Forwarders feature double-acting cylinders, gear motors, and directional control valves to load and transport logs efficiently from the forest to a collection site.

GRINDERS

Grinders are powered by piston motors, gear pumps, and directional control valves, enabling the effective processing of wood waste into smaller pieces.

HARVESTERS

Harvesters utilize radial piston motors, axial piston pumps, and proportional valves to control cutting, delimbing, and processing functions, ensuring efficient tree harvesting.

LOG LOADERS

Log loaders use vane motors, telescopic cylinders, and flow control valves to maneuver logs efficiently during loading and unloading operations.

SKIDDERS

Skidders are equipped with radial piston motors, gear pumps, and directional control valves to drag logs from the forest to a collection point effectively.
