斗式提升机 利用均匀固接于无端牵引构件上的一系列料斗，竖向提升物料的连续输送机械。
Bucket elevator uses a series of hoppers evenly fixed on endless traction components to upgrade the continuous conveying machinery of materials vertically.
斗式提升机具有输送量大，提升高度高，运行平稳可靠，寿命长显著优点，其主要性能及参数符合JB3926----85《垂直斗式提升机》（该标准等效参照了国际标准和国外先进标准），牵引圆环链符合MT36----80《矿用高强度圆环链》,本提升机适于输送粉状，粒状及小块状的无磨琢性及磨琢性小的物料，如：煤、水泥、石块、砂、粘土、矿石等，由于提升机的牵引机构是环行链条，因此允许输送温度较高的材料(物料温度不超过250 ℃)。一般输送高度最高可达40米。
Bucket hoist has the advantages of large conveying capacity, high lifting height, stable and reliable operation and long service life. Its main performance and parameters conform to JB3926-85 "Vertical Bucket Hoist" (the standard refers to international standards and advanced foreign standards) and the traction ring chain conforms to MT36-80 "High Strength Mining Ring Chain". The hoist is suitable for conveying powdery, granular and small pieces of non-polishing and small-polishing materials, such as coal, cement, stone, sand, clay, ore and so on. Because the hoist's traction mechanism is a circular chain, it is allowed to convey materials with higher temperature (material temperature does not exceed 250 C). The conveying height can reach up to 40 meters.
