FIELD: mining industry; mine electric locomotives.
SUBSTANCE: invention relates to means aimed at increasing wheel-road adhesion, namely, to sanders and checking of amount of sand in sanders. Proposed sander contains sand box. Ultrasonic vibration sensor is secured on sand box wall, output of sensor being connected with input of indicator. Said sensor is secured on sand box wall in its lower part through ultrasonic vibration insulator.
EFFECT: improved safety of rail vehicle in operation owing to checking presence of sand in sander and prevention of operation of electric locomotive if sander is empty.
