Directions: to indicate the position of the landing. Stop: the forearm level is placed on the chest, the fingers are outstretched, palms facing down, the horizontal wave to the side.

Q:What is the meaning of single speed, double speed, and frequency conversion speed of crane operation?

The speed of the speed of the crane, the speed of the speed of the crane, the speed of the variable speed is: A crane running single speed means that there is only one running speed. Crane running double speed is refers to a faster running speed, there will be a slower speed, speed of the two is driven by two different motor, with a slow speed motor and a fast. Crane operation frequency control of motor speed is by changing the frequency of the input motor power, so that the motor has different speed, thus make the crane has the speed of change.
