Abstract

Abstract A safety equipment system for operators of power machines comprising an operator''s safety equipment holder located adjacent to the power machine and a safety equipment switch carried by the equipment holder. The safety equipment holder includes a switch operator arm extending outwardly from the equipment holder for attaching the safety equipment thereto. When the safety equipment is supported on the operator arm, the operator arm will engage the safety equipment switch to hold the same in an open position; conversely removal of the safety equipment from the operator arm will cause the safety equipment switch to close. A safety floor mat is located at the operator''s position adjacent to the power machine, and a mat switch is carried by the floor mat and operable by the operator standing thereon. A machine power switch is carried by the machine and operably connected to the machine through the equipment switch and the mat switch whereby activation of the equipment switch and mat switch is necessary before power is applied to the machine. An equipment use reminder lamp is disposed on the equipment holder and operably connected to the power switch through the equipment switch. An alarm is disposed adjacent to the power machine and operably connected to the power switch through the equipment switch and the mat switch whereby, upon closing the power switch, the equipment use reminder lamp is activated, and upon activating the mat switching means, the alarm is activated, if the safety equipment has not been removed from the operator arm.
