1. Take emergency measures to the manufacturer to ask for help except for all spare parts outside the shell.
2. Adjust the vertical degree of the shell: due to the limitation of the housing beam, and consider the length direction deviation has little effect, did not make adjustments.Only the width direction deviation is adjusted, which is tuned to 12mm by L0LMM and adjusted to the allowable range.
3. In order to improve the ring impact breaking strength, the use of 25CrMoV manufacturing card ring.In order to reduce stress concentration, threaded empty knives should be eliminated in the future.
4. After the hopper assembly, both ends of the bucket should be welded,
5. Educe the discharge of the slant plate and Hopper gap, in order to prevent accidents and consider material humidity, on the slant plate attached to the F4 lining plate.
6. Passive wheel screw adjustment changed to free lifting, lifting machine air transport line, chain relaxation, load when the chain tensioning, at any time need to adjust; Due to wear, the chain gradually elongation also needs to be adjusted. The original structure is screw adjustment, to loosen, tight splint on the 16 bolts, the left shell from the large tank only 160mm spacing, no working space, cumbersome operation difficulties.Change the screw adjustment fixed skateboard to sunken wheeled active skateboard, increase the counterweight in the middle of two passive wheels, must 530/must 90X208 steel plate seven pieces, weigh 234kg, the total weight of the passive wheel 455kg, equivalent to half of the ring chain and bucket weight,
7. Strengthen the operation and maintenance of bucket hoist.
