In the previous article,(click here to see the previous article) four points about the use of drop-down concrete mixer should pay attention to, and then we continue to analyze.
(5) After starting the concrete mixer, the mixing drum should be fed after reaching the normal speed, and water should be added in time after feeding. Adding new materials must first unload all the original concrete in the mixer before proceeding. Mixer shall not be started when stopping or full load, except for reverse discharging.
(6) In the use of concrete mixer, do not let sand and gravel fall into the running part of the machine, so as to avoid the damage of the running parts. After the upper hopper is lifted, no one can pass or stay under the hopper, so as to avoid accidents caused by brake failure. If it is necessary to repair or clean up under the hopper, stop the machine forcibly and fasten the safety chain of the hopper.
(7) In operation, if it is found that the failure can not continue to operate, the power supply should be cut off immediately, the concrete in the mixing drum should be cleaned up, and then repaired.
(8) After operation, the mixer should be thoroughly cleaned. When the operator needs to enter the cylinder for cleaning, he must cut off the power supply, set up a special person to monitor outside, or unload the fuse and lock the gate box before entering.
(9) The rocking handle of the hopper shall be fixed by a pin so as not to cause the hopper to be lifted and extruded by touching the rocking handle of the body when people enter the simple cleaning room.
After operation, the hopper should be lowered to the hopper pit. If it needs to be lifted, the chain should be fastened.
