由长沙建筑机械研究所、南通市建筑机械厂和河南省水利机械厂联合设计的JZ500型双锥反转出料混凝土搅拌机,由南通市建筑机械厂首先试制成功,并于1988年4月6日在南通市通过部级鉴定。该机采用摩擦轮双边驱动和夹持轮轴向定位,有效地防止了摩擦轮遇水打滑现象和搅拌筒的轴向窜动。经过575小时使用考核表明,该机性能良好,受到用户好评。鉴定委员会经对该机进行性能复测,一致认为该机设计合理、结构新颖,试制是成功的。该产
The JZ500 double cone inverted output concrete mixer jointly designed by Changsha Construction Machinery Research Institute, Nantong Construction Machinery Factory and Henan Water Conservancy Machinery Plant was first successfully built by Nantong Construction Machinery Factory and was completed on April 6, 1988. Nantong City passed the ministerial appraisal. This machine adopts double-side drive of the friction wheel and axial positioning of the clamping wheel, effectively preventing the friction wheel from sliding in water and the axial movement of the mixing drum. After 575 hours of use assessment shows that the aircraft performance is good, praised by users. The appraisal committee reconsidered the performance of the aircraft and agreed that the aircraft was designed with reasonable design and novel structure, and the trial production was successful. The production
