First, when the Trailer Concrete Pump running mixing concrete mixer was found to have collision sound, there may be a mix of scraper shovel or loose or warping and resulting in the mixing drum caused by a collision, can be connected with bolts with a shovel or scraper, clearance between scraper and shovel repair, adjustment mix cylinder wall to solve.

Two, when the Trailer Concrete Pump mixer mixing shovel rotation is not working, abnormal sound, the reason may be: 1, mixing device buffer spring failure. 2, mixing material with large particle material stuck shovel. 3, too much material, power overload, at this time can be taken to replace the replacement spring, remove the card race of the material, according to the provisions of the feeding capacity of the solution.

Three, when the concrete mixing pump in the process of unloading the door leakage occurs, it may be because the door is not closed tightly or unloading door around the residual adhesive is too thick. At this point you can bolt to adjust the unloading below the floor, the discharge door closed tight, remove residual bond materials; when the concrete mixing pump hopper unstable operation, probably because the feeding orbit warp, bad contact roller hopper. At this point you can check the adjustment of the two tracks, so that the track straight, parallel to the rail surface.
