1. Familiar with the use of the crane, performance, operation and maintenance rules.
2. Strictly abide by the safety and technical rules.
3. The crane should do before starting operation.
4. Understand the power supply situation, whether there is a temporary power failure maintenance situation.
5. The crane must be monitored with the total knife switch disconnected, check the connection and use of important parts, and make necessary adjustments to individual mechanisms.
6. No tools or other items shall be left on the crane to avoid personal accidents or damage to machinery and equipment in the course of work.
7. Add lubricating grease to each lubrication point of the equipment according to regulations.
8. For cranes working in the open air, open their fixtures first and then operate them.
9. Before the main switch is connected to the power, the driver must turn all controller handles to zero. And the control room to go to the platform of the warehouse cover and the end of the beam door closed. 
10. Before each start of the crane, must issue a driving warning signal (electric bell) must be aware of the lifting of the lifting weight shall not exceed the rated lifting weight.
11. The driver must work closely with the lifting work, moving and lifting heavy objects, should only listen to the signal issued by the hooker, but the stop signal, regardless of who issued, should be immediately stopped.
12. lifting heavy objects, must be in a vertical position, do not allow the use of mobile trolley or trolley to drag heavy objects or tilt lifting.
13. The size of the crane must run at the slowest speed close to the limit position.
14. The crane's controller should be turned on gradually. Before the machinery completely stops running, it is forbidden to reverse the controller from the down position directly to the reverse position for braking, but it can be used to prevent accidents from happening.
15. The driver should ensure that the crane to prevent the crane in another crane collision, in the case of a crane failure, before allowing the crane to push the crane, in this case, both cranes are not allowed to lift heavy objects.
16. In the case of a significant reduction in voltage and power interruption. The total knife switch must be disconnected, all the controllers turn to zero position.
17. When the crane motor suddenly stops or line voltage drops sharply, all controllers are pulled to zero position as soon as possible. The main switch of the driver's room must be cut off. If there is a heavy load on the crane hook during a power failure, the driver and hooker should warn anyone not allowed to pass under the heavy load.
18. When the crane lifts heavy objects or puts down the hook, the driver must not leave.
