Caterpillar has introduced the outcomes of its prototype demonstration mission for a battery-powered area elevator with Flory Industries, a specialist within the manufacturing of nut-harvesting tools.
Accomplished through the fall harvest season within the Central Valley area of California, the sector check efficiently confirmed how a 600-volt battery-powered powertrain can ship the efficiency, reliability and sturdiness at present supplied on this utility by a standard 74-horsepower diesel engine whereas lowering upkeep and working with zero tailpipe emissions.
Supported by Holt of California, the native Cat seller, the prototype was examined over seven weeks within the almond and walnut orchards in California, with one website being Heinrich Farms, a 1,200-acre crop farm primarily based in Modesto. Right here, the unit operated a complete 10-hour workday on a single cost, loading 422,000 lbs of nuts into trailers all through the check.
To beat the constraints of being off-grid, Heinrich Farms totally recharged the electrified area elevator in a single day throughout non-working hours utilizing the Cat XES60 Compact ESS cell battery power storage system, which gives as much as 56.8kWh of capability.
“The electrified area elevator from Flory was dependable and unloaded our harvest as quick as typical tools powered by diesel engines whereas producing far much less noise,” says Jerad Heinrich, orchard supervisor for Heinrich Farms. “It lasted a complete day of labor with out stopping for a recharge, and we’re keen to make use of it once more for our subsequent harvest because the know-how continues to progress.”
The mission was the primary presentation of a prototype machine by a third-party OEM utilizing Caterpillar’s battery-powered answer. Based mostly on the optimistic outcomes of the demonstration, Flory plans to supply pilot models to pick prospects later this 12 months, with full manufacturing anticipated in 2026.
“The elevator is an ideal utility for electrified machines because it sits idle for many of the workday,” says Tyler Hupp, product growth supervisor for Flory Industries. “This collaboration was a possibility to indicate our dedication to delivering superior applied sciences to our prospects that enhance efficiency sustainably.”
Area elevators are utilized for harvesting all tree nut crops, which embody almonds, pecans, hazelnuts, macadamias and pistachios. Used for transferring nuts into trailers or stockpiles, area elevators can course of wherever from 50,000 as much as 250,000 lbs. of nuts daily through the fall harvest season.
Sometimes, area elevators powered by diesel engines spend about 80% of their responsibility cycles at low idle in between hundreds, which accounts for about 45% of their complete gas consumption. These lengthy intervals of non-productive operation interspersed with the necessity for instantaneous energy make the elevator a great goal for electrification.
By changing the standard engine with an electrified powertrain, the brand new system can eradicate as much as 126 lbs. of carbon emissions per machine within the area every day whereas eliminating diesel gas buy, transport and storage prices and lowering ambient noise for close by employees.
With the assist of the XES60, the sector elevator was capable of work off-grid through the day and be charged in a single day.
Caterpillar supported the mission by evaluating system necessities, optimizing system architectures, managing system controls growth, calibration, and verification and performing ultimate system validation.
Engineers built-in the batteries with inverters, motors, digital controls, digital providers and different essential applied sciences in a power-dense answer that addresses frequent consumer considerations whereas demonstrating the quite a few advantages.
The electrified powertrain featured Caterpillar’s new prototype battery, which makes use of lithium-ion know-how and contains a modular design to spice up efficiency whereas minimizing packaging. Caterpillar is creating a spread of batteries for the off-highway trade.
Holt of California utilized its particular data of Flory’s tools structure and responsibility cycles to supply day-to-day engineering, integration and testing assist.
Flory engineers coordinated the demonstration mission from the Flory Industries’ headquarters and growth centre in Salida, California, with assist from Caterpillar and Holt of California’s groups situated within the Sacramento space. Flory has specified Cat diesel engines for powered tools all through its fleet of agricultural tools since 2002. The corporate at present makes use of US EPA Tier 4 Last Cat engines for self-propelled harvesters, shuttle vehicles, elevators and brush shredders.
The battery-powered elevator is designed to be configured with Cat Join, enabling tools house owners and Cat sellers to remotely monitor efficiency throughout operation and charging cycles. This intelligence can then be leveraged to enhance productiveness by optimizing in-use and on-charge processes.
“We’ve gained helpful insights from working with Flory to use our data of electrification and high-voltage methods to the difficult environments of working California farms,” says Steve Ferguson, senior vice chairman of Caterpillar Industrial Energy Techniques. “This mission demonstrated how Caterpillar is efficiently aligning with fellow innovators to develop applied sciences that maximize the efficiency and reliability of electrified machines at real-world worksites. Caterpillar can present prospects with entry to the total ecosystem of parts to insights and the charging infrastructure.”
