Several ways of controlling the bridge crane
The weight should be moved along the upper, lower, left, right, front, back, and in a three-dimensional direction. In addition to the downward movement, terminal protection should be set in all five directions. Be sure to have a reliable brake device, and even if the power is out, the weight will not fall.
The mode of control of the crane; (driver's room), floor (handle switch, remote control), space two (handle switch or remote control and driver's room).
There should be a wide range of speed adjustment, and at the beginning of the motion of the stationary state, the acceleration should begin at the lowest speed and the acceleration should not be too large. In order to prevent the risk of overloading or speeding, there should be a temporary overload protection measure. It is generally used as the overload protection of the circuit. Be under pressure to protect yourself. Have safety measures.
