When the power circuit breaker is locked or there is a notice board, the main power supply can be turned on only after the original person concerned removes it. 2. Precautions for safe operation at work: 1. When lifting heavy objects for the first time in each shift (or when the load reaches a large weight), the heavy objects should be lifted 0.5 meters above the ground, and the brake performance should be checked. After confirming the reliability, proceed to normal operations. 2. Strictly implement the 'ten no hanging' system: ①The command signal is not clear or the command is not hoisted; ②Do not hoist when the rated lifting capacity is exceeded; ③The spreader is used unreasonably or the object is not hung tightly; People or other floating objects do not hang; ⑤The brakes or other brake safety devices fail and do not hang; ⑥The heavy objects are not hoisted when the crane is hoisted directly for processing; ⑦The objects are not hoisted when they are slanted and slanted; ⑧ Objects do not hang; ⑨ Objects buried in the ground should not be lifted; ⑩ Objects with corners and corners should not be hoisted if they are not properly padded; 3.
