Electric gourds are widely used in factories and are commonly used handling equipment. Electric gourd has the characteristics of small size, light self -heavy, simple operation, convenient use, etc., mainly consisting of two parts: walking mechanism and promotion mechanism. The walking mechanism of electric gourds is mainly composed of walking motors and transmission mechanisms. Walking motors are mainly electric sports cars, ensuring that electric gourds can achieve the function of walking left and right. The transmission mechanism mainly includes electrical devices (internal electrical components to control the normal operation of electric gourds) and connecting device (connecting the main (quilt) dynamic wheels and passive wheels). The promotion mechanism of electric gourds is mainly composed of improving motors, rolling agencies, and mechanical brakes. The role of the rolling of electric gourds to lift the motor is mainly to provide motivation for rolling machines, with braking devices. The role of a lifting mechanism reducer is mainly to change the motor output shaft speed and pass the power to the roller. The speed after the deceleration is generally 8m/min-16m/min. Electric gourd is a special lifting equipment. It is installed on the cars and Dragon Gate. The electric gourd has the characteristics of small size, light weight, simple operation, convenient use, etc. It is used for industrial and mining enterprises, warehousing, docks and other places.
