Smart-Trac Self-Tensioner Extends Paver Life: SMARTRAC

By Charlotte KempOctober 01, 2021

Not Too Loose, Not Too Tight, Always Just Right

SMARTRAC is BOMAG’s belt tension solution that prolongs the life of your track and greatly reduces the likelihood of a de-tracking. The self-correcting system maintains just the right amount of tension on your track to optimize performance without being too loose, causing the belt to de-track, or too tight, putting an unnecessary load on your drive components. That balanced tension means a smoother operation, more up-time, a lower operating cost, and greater peace of mind for you.

The Problem

“Proper belt tension is critical to the operation of your paver,” says BOMAG Paver Product Manager Ray Gonzalez. “When it’s not monitored consistently, track sag and wear can cause excessive downtime and bring your operation to a grinding halt.” Checking your tracks on a daily walk-around is key to optimum performance and longevity, he says.

Track sag not only causes premature wear on the belt, but it can also cause de-tracking, when the belt is forced off the drive components, and can no longer propel the unit. “This all requires time, money and manpower to fix,” says Gonzalez. “When a de-track happens – or unscheduled downtime occurs due to prematurely worn track – efficiency, time and money are all put at risk.”

Unforeseen downtime due to de-tracking and premature track wear have significant cost impacts to your business, Gonzalez adds. “No job site can afford to have haul trucks waiting, time ticking away, and lost manpower.”

The Wrong Solution

“The typical approach to solving this issue with other pavers is to always maintain a high level of force against the carriage assembly,” according to Gonzalez. “Unfortunately, this approach significantly increases the load on the drive components of the unit during normal operation. Many system components are then exposed to increased wear and tear, which leads to premature system failure.”

Most of the time, correcting the issue involves adding tensioning devices or idler assemblies that automatically adjust. “But usually these corrections are not made until the problem occurs,” says Gonzalez,“which is too little, too late for your needs.”

The Right Solution

SMARTRAC solves this problem for you without any manual work or extra down-time, according to Gonzalez. BOMAG’s exclusive solution is powered by a patented self-adjusting hydraulic system to monitor and control the amount of track tension.

Whether it’s propelling forward or in reverse, SMARTRAC adjusts track tension for a smooth ride and continuous optimum track contact with the ground. Sensors then monitor the operating conditions of the paver and adjust track tension to continue to perform at optimum levels.

“A smoother ride, less manual adjustments and peace of mind is something your operators will appreciate,” says Gonzalez.
