The HL type ring chain hoist is suitable for vertically conveying large powder, granular, and small block materials such as grain, coal, cement, crushed ore, etc., with a maximum conveying height of 40m. Its characteristics are: simple structure, smooth operation, scoop type loading, mixed or gravity unloading, combined sprocket wheel rim for easy replacement, special treatment of sprocket wheel rim for long service life. If a gravity automatic tensioning device is used in the lower part, it can maintain constant tension, avoid slipping or detachment, and at the same time, it has a certain tolerance to effectively protect moving objects when the hopper encounters resistance. The material temperature does not exceed 250 ℃ The TH type is designed and manufactured according to your JB392-85 "Vertical Bucket Elevator" standard, and should be prioritized for use. Except for the link size, the chain, sprocket, and tensioning device of the HL bucket elevator are the same as those of the TH type.

　　Working principle

　　The HL type circular chain centrifugal bucket elevator consists of a moving part (hopper and traction chain), an upper section with a transmission sprocket, a lower section with a tension wheel, an intermediate housing, a driving device, a reverse braking device, etc. The hopper of the elevator is arranged intermittently, using the "digging method" for loading and the "centrifugal feeding method" for unloading. The traction mechanism of this elevator consists of two circular chains.
