The ER Boom System

ER technology allows the operator to actuate the boom with optimal hydraulic efficiency. Extend and retract on a horizontal plane quickly and smoothly with a single joystick.

The patented ER┬« boom system allows the machine operator to extend and retract the feller buncher boom on a horizontal plane smoothly and quickly using a single joystick. The stick boom or “reach” joystick controls both the main and stick booms simultaneously, resulting in the attachment moving either away from or toward the operator.

ER technology® is bringing revolutionary improvements to tree harvesting not seen since the invention of the high-speed disc saw 20 years ago. Important advantages of the ER boom system include improved fuel efficiency, increased production and reduced operator fatigue. Also, training for new operators is a far less daunting task.

ER boom technology

Conventional boom systems are fundamentally inefficient at felling because they must mix two arcing motion functions to get the desired reaching motion. Conversely, the patented ER boom system allows the machine operator to extend and retract the boom on a horizontal plane smoothly and quickly using a single joystick. The stick boom or “reach” joystick controls both the main and stick booms simultaneously, resulting in the attachment moving either away from or toward the operator. The main boom and tilt functions operate in the traditional manner to adjust the height and angle of the attachment.

Key to this technology is reduced energy consumption. The ER system transfers energy back and forth between the main and the stick boom functions, reducing the total energy needed to move the boom system. This translates to reduced demands for power, pump flow and system cooling. Operators who have spent time on ER machines comment on the speed, ease of operation and smoothness of the boom as well as the extra horsepower available for other functions and faster saw recovery.
