HL系列斗式提升機是TH型斗式提升機的更新換代產品，該型提升機與TH型相比，具有輸送運量大、提升高度高、運行平穩可靠、壽命長等優點，主要技術性能及參數符合有關國家標準。

HL系列斗式提升機結構特點：

1、料斗斗容與實際填充量相近，加之運行速度提高，比相同斗寬的TH型斗式提升機的輸送量增大近一倍；

2、上下鏈輪采用組裝式結構，可方便更換輪緣，降低維修費用； 

3、牽引件為強度較高的圓環鏈，經熱處理后具有較高的抗拉強度和耐磨性，因而使用壽命長。

HL Series Bucket Elevator is replacement product of the TH type bucket elevator, compared with TH series bucket elevator,it has the feautures: large volume of transportation, high height, stable and reliable operation, long lifetime,etc.the main technical performance and parameters can meet the national standard. Structural characteristics: 1、The volume of hopper is similar to the actual content, high operating speed,  compared with the same width of the TH-type bucket elevator, the transmission capacity increases double; 2、Upper and lower sprocket use assembly structure, can easily replace the rim & reduce maintenance costs; 3、Pulling pieces of high strength ring chain, after heat treatment, it has higher tensile strength and wear resistance so that it has long life.
