Maxam's Chain Assembly Tool
The Little Known Truth About Chain Assembly
It's a little known truth that many chain failures are the result of improper assembly.
Chains are necessarily designed with an interference fit between the pin and the side bar. The interference fit provides an essential preload on the sidebar. Without this preload, the chain is subject to constant loading/unloading as it traverses the conveyor. Much like bending a wire back and forth, the constant loading/unloading causes the sidebar to fail from fatigue stress.
In a shop, it is easy to install the pin with a press, but in the field, personnel generally have little more than hammers. In the constrained confines of a conveyor, it is nearly impossible to get an adequate blow from a hammer to drive in a pin. What does the installer do? He often resorts to grinding the end of the pin to facilitate the assembly - dooming that connection to almost certain premature failure.
A fate easily avoided with a Maxam Chain Assembly Tool -- which, unlike other chain tools, works easily inside the conveyor box.
