Elevator Belt Selection - Suspended Weight Method<br />
This chart, when filled in completely, will indicate the proper elevator belt to use in terms of tension. Other factors such as bucket projections, chemical and/or heat<br />
exposure, and service conditions will influence the type of belt to select.<br />
