First make sure people have learned about the operation of the operating instructions, everyone clear their responsibilities RTG runtime.
Because the case RTG crane is special equipment, there should be full time safety inspector; electrician and operator. Have a strict construction organizations and measures to ensure construction safety. The operator must be in strict accordance with state regulations, "crane safety technical rules" in the job.
Firstly installed RTG conduct a comprehensive inspection, see the installation is in place, a seamless installation, wrong equipment, the connection is secure. Check the electrical wiring is correct; the limit switch is sensitive and reliable; check the mechanical and structural parts have wiring. Check all moving parts lubrication. Check the rope, before proceeding with the job chain is broken, the circuit for leaks, ground wire is connected to reliable braking is reliable, each gear and add a little oil to lubricate the rear sprocket.
Start the generator, power, check the line for leaks. Were turned on the alarm, warning bells and various parts of the lights a few times to make sure it is working properly.
Jog carts walk button, check the driving wheel carts two walking directions are the same, then walk for several pros and cons to check whether the travel agency is running smoothly, the two drive motors are synchronized operation, whether the brake balance.
Hoist lift load test done to check the reliability of each trip switch, wire rope safety checks carried out, and check retractable rope is normal.
After the end of the experiment above, during heavy load test, the first trial in accordance with the nominal weight lifting, stopping to observe any abnormal 5cm entire tire hanging in heavy lifting off the ground, and then repeatedly lifting weights a few times, check the brake is reliable.
Travel agencies overloaded walking test, the rated lifting heavy objects off the ground 30cm, were walking test, again check the brake is reliable, walking without exception, found that the problem should be treated
