Double girder overhead crane: Introduction: 1. double girder overhead crane operating room separate, closed, holding three. 2. The double girder overhead crane cab platform side entrance points, end, top three. 3.H. To increase the height of the bumper carts. 4. double girder overhead crane at the indoor, indoor two kinds. Maximum and minimum temperature and power requirements for the types of orders should indicate the technical work environment. 5. Increase the overload limiter, large-screen displays and various protective devices single bridge crane, further increasing the use of safety. 6. double girder overhead traveling cranes are generally used for the air operation, he is different from other places operated crane. Empty crane operation is following a separate small operating room, and to exercise is the operator holding the remote control. The correct method of operation: run institutions within the scope of short distance running, should be selected according to the specific circumstances of the controller handle should be in place. If you run long distances institutions operating within range, must take the controller handle stepwise to the last level, so that the motor is running at high speed electric hoist bridge crane, so that both the motor is good, but the work efficiency too high, and save power. Hoisting mechanism when there are objects hanging hook, and finally by the rising level of the control handle back to the zero position, must remain slightly (1 second) in the middle of each position. Such as when overloaded, the handle on the second level should remain one more would be better, thus reducing the vibration when stopping hook. Crane starting to have a smooth and gradually accelerated stall. Lifting mechanism for each file conversion time of 1-2 seconds, run the agency each file conversion time is not less than three seconds.
