Recently Caterpillar had a virtual press event since such actual events have been on hold since last March during CONEXPO-CON/AGG & IFPE 2020 which was held in Las Vegas Nevada, drawing over 130,000 attendees. The show was held at the beginning of March which as we all know happened to be the beginning of COVID-19. I did attend the show arriving on March 3 and fortunately departing on the ninth. Little did I know that I the next press events I would be attending would be virtual.
In addition to Cat there have been other virtual press events and there are more to come. Also, industry trade shows are returning. There have been a couple and as you may or may not know, the World of Concrete show is scheduled from June 7 – 10, 2021 Las Vegas NV and the Utility Expo (Formerly ICUEE) is scheduled for September 28 – 30, 2021 Louisville, KY.
The Cat virtual press event focused on Paving and Load-and-Haul products. This included a look at: Single Drum Vibratory Soil Compactors including the new Cat G Series single drum machines; Utility Compactors with the introduction of ten new compactors in the 2- to 5-ton weight range; Cold Planers including numerous updates to existing models; Soil Compactors reviewing their enhancements and updates; Landfill Compactors introducing the New Cat 816 Landfill Compactor improves uptime reliability, lowers maintenance and increases operator productivity; Wheel Tractor Scrapers introducing the New Cat 657 Wheel Tractor-Scraper increases productivity, enhances operator comfort; Track-Type Tractors featuring the New Cat D9 Dozer designed to lower owning and operating costs for applications worldwide; and Large Wheel Loaders highlighting the New Cat 992 Wheel Loader increases productivity up to 32% and is up to 48% more efficient.
I’d like to highlight a couple of these machines starting with the New Cat® 657 Wheel Tractor-Scraper which according to Cat increases productivity, enhances operator comfort and delivers low-cost earthmoving. It Features the field-proven, twin-power design to boost cycle times, the new Cat® 657 Wheel Tractor-Scraper (WTS) elevates productivity and operating efficiency to deliver low-cost earthmoving. A 7% increase in fuel efficiency over the 657G WTS means more material moved per unit of fuel burned, and improved onboard payload estimating accuracy helps optimize productivity. The largest open bowl scraper in the Caterpillar line, with a rated load of 52 tons, now has a more spacious cab to boost operator comfort and efficiency in high volume earthmoving, highway construction and mining applications. The 657 features on-the-go weighing through Payload Estimator, allowing the new WTS to achieve 95% load accuracy, so operators more easily reach target load goals.
The new Cat® D9 Dozer replaces the D9T model and offers customizable configurations to meet application needs around the world. Built on a legacy of longevity and proven reliability in the field, the new Cat D9 lowers overall costs per unit of material moved by up to 3%. Efficiencies gained through a new torque converter with stator clutch reduce fuel consumption by as much as 5%, and the new dozer reduces maintenance and repair costs by as much as 4%. The new dozer features the proven Cat C18 engine, which has a range of exhaust aftertreatment solutions available, including configurations to meet U.S. EPA Tier 4 Final/EU Stage V regulations and configurations equivalent to U.S. EPA Tier 2 and Tier 3. The D9 also features differential steering for a tight turning radius and the ability to maintain ground speed while turning—to keep productivity high. The suspended undercarriage delivers more track contact with the ground for less slippage and greater productivity.
The new Cat® 992 Wheel Loader increases productivity up to 32% and is up to 48% more efficient being powered by the new Cat C32B engine with U.S. EPA Tier 4 Final/EU Stage V and Tier 2 equivalent emission engine options, the new 992 meets the global industry’s demand for high-production equipment with greater payloads. Powertrain design enhancements to the transmission, axles and final drive, along with the new engine, deliver a 20% longer interval for planned component replacement. Offering both standard- and high-lift configurations, the 992 delivers the lowest cost-per-ton when paired with fleets of Cat 775, 777 and 785 trucks. Standard-lift payload capacities reach 25.5 tons for quarry face applications and 30 tons for loose material handling, while high-lift capacities reach 22.5 tons and 24.5 27 tons in respective applications.
A new Z-bar linkage optimized for performance, and improvements to rimpull and breakout force, deliver greater machine capacity and efficiency. The new 992 has demonstrated in field testing up to 48% greater payload-per-fuel efficiency in applications where a four-pass match to 100-ton trucks was achieved, versus five passes with the 992K. The powerful and efficient 992 provides up to 9.5% more rimpull during digging and up to 20% more breakout force, increasing productivity.
