The potential of hand tractor controller to reduce the risk of Hand-Arm Vibration Syndrome (HAVS)

Abstract

Hand-Arm Vibration Syndrome (HAVS) is a disorder caused by vibration of work tools that vibrate the hands excessively or above the threshold. The impact of Hand-Arm Vibration Syndrome (HAVS) over a long period of time causes damage to blood vessels, permanent sensory loss, bone damage and muscle weakness. One of the workers with the presence of Hand-Arm Vibration Syndrome (HAVS) is a hand tractor driver. To reduce vibrations received by hand tractor drivers that could potentially cause Hand-Arm Vibration Syndrome (HAVS), a tractor control device was built by implementing the Internet Of Things (IoT). The hand tractor control device developed utilizes an Android-based application as a remote control, an access point as a connector, an electronic circuit based on the ESP8266 MCU Node to translate commands from the android application into motion to move the main clutch lever to forward and stop, gas lever, and gear clutch to turn left and right.
