RUNNING ALARM DEVICE FOR CONSTRUCTION MACHINE

摘要

PROBLEM TO BE SOLVED: To provide a running alarm device capable of restraining noise generation without any need of automatically changing the level of an alarm sound according to operating conditions of a construction machine for control operation of the sound level. SOLUTION: This running alarm device includes: a speed sensor for detecting a running speed; an alarm sound generator for generating an alarm sound; and a controller. The controller operates the alarm sound generator when a detection signal of the speed sensor is in a running state and sets the sound level so as to be higher as a running speed is higher.
