The aggregate industry provides crushed rock that becomes a component of asphalt and concrete used primarily in highway, bridge, runway, sidewalk and building construction.

When aggregate crusher and shaker screen equipment breaks down and halts your operations, the downtime can cost you thousands of dollars in lost tonnage production per hour. Belt failures occur due to six common problems:

Improper tension 
Misalignment 
Improper handling 
Hardware 
Environmental factors 
Drive design 
Aggregate Facts

Construction of a one-mile stretch of two-lane highway requires approximately 25,000 tons of crushed rock. 
More than 1.5 billion metric tons of crushed stones were produced in the U.S. in 2003. 
Over half (53 percent) of crushed stone production in the U.S. comes from 10 states in descending order: Texas, Pennsylvania, Florida, Illinois, Georgia, Missouri, Ohio, Virginia, North Carolina, and California. 
Aggregate is one of the world's oldest industries, yet business is booming, accounting for approximately $10 billion in sales annually. 
Roughly 1,200 companies operate 3,200 active quarries in the U.S. 
Average annual growth is around 9%.

Gates new Cotton Cleaner Belt was tested on nearly 20 cotton gin machines last season in Texas. It was one of the state’s largest cotton producing seasons ever. Gates Cotton Cleaner Belt outlasted and outperformed the belts it replaced.

Ocean Racing Yacht 
When a mechanical gearbox system wouldn’t work to drive the canting keel on the ocean racer Maximus, designers turned to a Gates Poly Chain GT2 belt drive to get the job done. 


Car Shredder 
When a vehicle is shredded, the load on the 6,000-hp motor fluctuates rapidly. This destroys conventional belts on the hammer mill drive, but not Gates Predator v belt. 


Drag Racing 
The fastest cars in motorsports are driven by Gates Poly Chain GT 2 belt -- whether it’s on the Top Fuel dragster of three-time champion Tony Schumacher or on the machine driven by Melanie Troxel, the fastest female in NHRA history.

No food processing operation can afford downtime these days. It can cost you thousands of dollars in lost production per hour. One way to prevent costly downtime is the use of high quality Gates belt drive systems on your processing equipment and conveyor drive systems—from the introduction of raw materials to packaged products out the door.

Belt drives offer many advantages, especially when compared to roller chain, and can solve a wide range of problems to help you meet production goals and save money. Gates offers belt drives to address these concerns:

Lubrication and product contamination 
Washdown 
Rust Contamination 
Timing and synchronization 
Drive Location 
Replacement 

HVAC
Our V-belt and synchronous belt drive systems are that good. They virtually eliminate problems that rob HVAC systems of cost efficiency and optimal performance - like whipping, stretch, creep, vibration, wear and noise. 

ACHE
Air-Cooled Heat Exchanger Application Manual 

Air-cooled heat exchangers are used in Petrochemical, Oil and Gas Production, Power Generation, and Petroleum Refining Industries where process heat must be removed. The ACHE Application Manual provides technical drive design information as well as application and troubleshooting guidelines. The use of synchronous belting on these large-ratio drives often provides the designer an efficient and narrow package. Product ranges include reduced weight ACHE QD-Bushed sprockets for ease of installation, ACHE PowerGrip GT2 belting for use on vertical drives where tracking is a concern, and Nickel-Plated sprockets for use in Cooling towers or high humidity environments. 

Case Study 
"If you can solve this problem, then every belt drive in our mill will be converted to Gates, and Gates will be the hero of the sawmill industry."

- Kevin Freeman, Vice President, Bibler Brothers Lumber
This belt is ideal for all industrial markets, but particularly suited for Curve Saw applications or any shock loaded application requiring synchronization.

An innovative construction combined with the Gates tooth profile makes the Curve Saw Poly Chain® GT®2 Belt compact and lightweight with extraordinary strength and load carrying capacity.

Features/Advantages

Gates patented curvilinear tooth profile provides high shear strength and improved load carrying capacity. 
Unique aramid tensile cord combines extraordinary strength and superior shock load capacity. 
Significantly reduces log jams and associated down time. 
Nylon tooth facing reduces friction and eliminates the need for lubrication. 
Fully operational in temperature extremes of -65° F to +185° F (-54 C° to +85° C). 
Industry: 
Lumber Mills: Lumber manufacturers install curve saws to increase the amount of board feet “recovered” from cutting a log into dimensional lumber.

In addition, curve saws can: 
• boost production
• improve lumber recovery ratios
• reduce labor costs
• stay competitive
