Bucket Elevator Chains A bucket elevator is a conveyor in which buckets are installed on a vertically circulating chain, to vertically convey loads of granular powder. There are two series of bucket elevators: NE Type (standard speed) and NSE Type (high speed). Both types have wide-ranging applications.
(a) NE Bucket Elevator Chains
An NE type bucket elevator is a general-use bucket elevator that operates at a normal conveyance speed. The elevator is manufactured with two types of chains: Standard Conveyor Chain with Attachment G4 (standard or heavy-duty) and DK Strong Z Conveyor Chain.

(b) NSE Bucket Elevator Chains
An NSE type bucket elevator is designed for high speed conveyance and the speed is about double that of NE type. To withstand high speed operation and to reduce noise and shock, the chain pitch is one-half or less of that of the chains for NE type. To ensure high durability, pins, bushings and rollers are the same as those for strong Z-type. Use the sprockets exclusive for NSE Bucket Elevator Chains.
