1. After the medium concrete mixer pushes the loading handle, the hopper cannot rise or it is difficult to lift
Cause of failure 1 Bad coupling of clutch brake band
2 The medium concrete mixer brake is too worn and the nail head is exposed
3 Oil on the brake belt
4 The medium concrete mixer connecting bolt of the loading handle and the horizontal rod is loose or the fastening bolt of the horizontal rod and the clutch fork is loose
5 Brake band falls off or deforms tightly
6 The sliding head of the fork comes off or is worn out
Troubleshooting method
1 Adjust the medium concrete mixer elastic contact bolts to make the brake band tight, eliminate the warpage of the brake band, and make the joint surface of the band less than 70%
2 Replace the brake band
3 Clean oil and dry
4 Retighten
5 Overhaul clutch
6 Repair welding or repair new slider
The hopper does not fall when the self-falling medium concrete mixer pulls down the handle
Cause 1 The outer brake band of the clutch is too tight
2 The material head lifts too high and exceeds 180 degrees, the center of gravity leans inward
3 Down handle does not work
4 Friction on wire rope reel shaft
5 The wire rope is deformed and overlapped
