CONSTRUCTION EQUIPMENT WITH HANDLE-MOUNTED VIBRATION SENSORS

Patentradars sammanfattning

This Husqvarna patent covers hand-held electrically powered construction equipment—primarily cut-and-break tools and power cutters—featuring vibration sensors embedded directly in the front and optionally rear handles. A control unit continuously monitors vibration levels reported by these sensors against predetermined acceptance criteria and triggers mitigating actions such as operator warnings, motor speed reduction, or full inactivation when thresholds are exceeded. The disclosure further encompasses vibration logging, daily exposure tracking per operator, kickback detection, flush-cutting capability via laterally offset battery placement, and a cost-effective single-spring vibration suppression arrangement for the front handle. The underlying sensor and control concepts are also claimed as applicable to forestry equipment such as chain saws.
