Thrust Roller Maintenance - Rolling into 2016

Posted by H&P Blog on Wed, Jan 06, 2016 @ 10:30 AM

Happy New Year! As we head into a new year many of us resolve to be less stressed, more efficient and in the best shape of our lives. Those same resolutions can often be applied to capital equipment.  So while you are setting those goals to improve your well-being in 2016, let us review the ways we can improve the life of our equipment. A few simple preventative maintenance items can make 2016 your continuous barge unloader’s best year yet.

Proper equipment maintenance is crucial in extending the useful life of any machine. For a continuous barge unloader the maintenance of trolley thrust rollers is paramount to efficient function. Without properly adjusted thrust rollers installed weight is redistributed to other components that are simply not designed to handle them. Thrust rollers are necessary to bare heavy loads.




Issues involving trunnion equalizers, rail or wheel flanges are often the result of poorly maintained thrust rollers.  Thrust rollers must be properly maintained to avoid a snowball effect of malfunction.


Regularly completing a visual inspection of the thrust roller can help to avoid long term damage. Be on the lookout for any side to side motion which would be a telltale sign that there is an issue.



It is of utmost importance that the rollers be lubricated regularly. Depending on the machine's usage level this may be once week, up to daily for machines that run 24/7.

Maintaining the integrity of the trolley thrust roller will prevent wear on the flanges of the trolley wheels, wear on the side of the main vertical rail head as well as excessive stress on the trunnion equalizer wheel frames.



Basic maintenance will help prolong the life of rails, trunnions, wheels and ultimately the life of the continuous barge unloaders.
