Bulldozer frame by welding tank and rear axle group formed legs, two different production processes, in order to avoid damage to the film set of welding, to take on the rack after the group carried out the bottom one to the finish of the paint, film effect, more than 85% gloss, adhesion to a meet quality requirements appearance.

Bulldozer trolley is finish the most difficult part of the implementation, because the trolley welding, paint after painting the bottom one processing step there, take in the processing of rubber underside shop, take a non-clamping position outside appearances, processing is completed After cleaning cutting fluid increases, up painting process to ensure that car appearance. Currently assembled components to achieve the finish of 30 bulldozers, painting, assembling efficiency increases, inventory enhanced corrosion resistance, the whole appearance quality dramatically.
