Installation of Chain Bucket Elevator

Installation of chain bucket elevator is very important to ensure it proper operation and longer lifespan. The chain bucket elevator is actually used chain as the transmission medium and enclosed it with a casing. The chain and shaft alignment maintenance are vital to ensure proper operation. Although alignment is checked by the manufacturer prior to shipment, correct and proper care must be maintained during erection to ensure a straight and plumb casing from head to boot section as a twist or leaning casing would prevent proper tracking of belt on the pulleys. 

Bucket elevators are comprised of three main assemblies which are head terminal, boot terminal and intermediate assemblies and components. All terminals are factory assembled and shipped assembled. For safety and shipping considerations, the drive assembly is usually not mounted on the head and the intermediate casing is shipping in individual pieces. Henan Pingyuan technical team will teach and train our customer employees regarding to installation and operating the bucket elevators. When assemble the casing, firstly, settling boot section and ten to twenty feet of intermediate leg casing. Use a plumb line from top to bottom to check vertical and level settling of boot on base using shims if necessary near anchor bolt holes (not at corners). Grout under boot after elevator is completely assembled. Assemble remaining leg sections respectively as marked by the manufacturer. Usually the boot will be marked “A” then the first leg section “B”, second “C” and etc. These marking will be located in the lower right corner of each section and after assembly can be readily checked by sight from top to bottom. 

In the installation of chain elevators, there are certain general practices should be followed: 
1.Chain selection 
-Select the best type of chain for the service to be performed. Consult your chain catalog or your nearest chain distributor to check for your selection. Henan Pingyuan will provide advice on the chain selection to our customer.

2.Proper Direction of Chain Travel
-Straight side bar chains operate equally well in either direction. No special instruction needed to be followed.

3.Take Ups
-A mechanical device for adjusting shaft center distance, should be provided for all elevators to compensate for elongation as joint wear occurs and to provide temporary slack for installation and maintenance work. 
-The take-ups on elevator should be mounted at the boot end to eliminate the troublesome adjustment of the drive if the take-up were mistakenly mounted on the head end.

4.Shaft and Sprocket Alignment
-Proper alignment of sprocket and shaft greatly lengthen sprocket and chain life. 

5.Mounting Elevator Buckets on Chain
-Elevator buckets are generally attached to chains by means of Hex or square head machine bolts with nuts. Spring lock washers or self locking nuts are recommended for all bolts used to attach buckets to chain to keep the bolts tight. On overlapping continuous buckets, a bevel washer is used between attachment and bucket.
