Mechanical products not only have the right but also the boot steps correct shutdown procedure, which is also very useful to the operator, but also responsible for their own personal safety, gunite shotcrete machine equipment have the right to be completed after shutdown step, so as to protect the shotcrete machine, we can guarantee the safe operation of construction workers, staff closed jets also measured voltages before shotcrete machine equipment, and is a professional voltmeter to measure the release of shotcrete machine equipment voltage stress parameters, the normal voltage should be between two hundred to two hundred and fifty volts volts, the voltage under such circumstances and then to be able to properly shutdown, while ground distance of the power cord from the operator to have a certain distance, but also pay attention to these connections, whether the purpose is to ground the power head, and taking its distance from the product sprayed area, whether it is in the above distance. Power cord not too long, the length of power line problems are mainly related to the length of the issue after its prolonged extension cord, the operator should gunite shotcrete machine equipment extension cord control within 90 meters of the power plug for the power cord, the operator can not freely removed, so as to be able to guarantee the operation of personal safety of the operator.
