Remove the bolt scenes of its own weight

Construction machinery construction work environment is more severe , than the sparsely populated remote mountainous areas, is the architectural Construction sites, landfills, and other national key projects , focusing on models, verification teams adhere to long Phase tracking verification, room and board are located in the device test site . China 's northernmost Mohe County , the annual level Average temperature -5 ℃. Concrete mixing plants, when the spring , Mohe is still cold of minus 20-degree, Bleak , wind up to eight . SD52-5 in China 's northernmost Mohe County, industrial Test , the validation staff long-term tracking verification , because SD52-5 bulky, body weight, while the right side Final Drive has three times the damage to be overhauled repaired.
