Abstract
A system for controlling a felling saw in a forestry machine, the felling saw being driven by a hydraulic pump and saw motor circuit. The system includes an instrument for measuring a rotational speed of the felling saw and generating a signal indicative of the rotational speed, a calculator for calculating a power consumption of the hydraulic pump and saw motor circuit adjusted as a function of the signal indicative of said rotational speed, and a controller for adjusting hydraulic settings of the hydraulic pump or/and saw motor circuit based on the calculated power consumption. A method for controlling the felling saw is also disclosed.
Claims8
A method for controlling a felling saw in a forestry machine during felling operation, the felling saw being driven by a hydraulic pump and saw motor circuit, the method comprising:
- measuring a variation in rotational speed of the felling saw during a felling sequence thereof and generating a signal indicative of said variation in rotational speed;
- calculating a power consumption of the saw motor circuit during the felling sequence and an adjusted power requirement for the hydraulic pump and saw motor circuit for a subsequent felling sequence, the power requirement being adjusted as a function of the signal indicative of said variation in rotational speed;
- adjusting hydraulic settings of the hydraulic pump and saw motor circuit based on the calculated adjusted power requirement;
- and
- initiating the subsequent felling sequence with the adjusted hydraulic settings.
