Komatsu’s first electric mid-size hydraulic excavator packs a Proterra battery

US battery maker Proterra and multinational Komatsu partnered in January 2021 to develop electric mid-sized hydraulic excavators, and today they announced that Komatsu’s first 20-ton class lithium-ion battery electric machine is ready for debut.

Komatsu will officially launch the electric excavator next week at bauma2022, a construction equipment trade fair in Munich. It will be introduced to Japanese and European markets in 2023.

Mid-size hydraulic excavators are versatile machines that are mainly used for earth excavation and loading operations.

Komatsu’s new electric 20-ton machine features a power output of 123 kw and 451 kWh of battery capacity.

(Contrast that with Caterpillar announcing in January 2019 that it was building the “world’s largest” excavator: a 26-ton machine with a 300 kWh battery pack.)

The new electric excavator’s Proterra battery system, when fully charged, enabled operation of five to nine hours in the proof-of-concept tests conducted on advance research machines at customers’ construction sites. Komatsu’s components on the machine include the hydraulic pump, controller, and electric motor for work equipment operation.

The added advantage of electrifying construction equipment is that it can be used for work in urban areas and during nighttime construction work without creating noise pollution or emissions. Komatsu also notes that “the zero engine vibration will also help reduce operator fatigue.”

In addition to making batteries, Burlingame, California-based Proterra also manufactures electric buses and drive trains and chargers for heavy-duty commercial vehicles.

Proterra is going to get some competition from Tesla, which announced on October 6 that its Tesla Semi has gone into production and that Pepsi is going to get the first electric trucks starting December 1.

The Motley Fool reported on October 14 that “Proterra shipped battery systems for 348 vehicles in the third quarter, a jump of more than 1,000% compared to the year-ago quarter.”

Caterpillar Launches CAT 350 Hydraulic Excavator

Caterpillar has unveiled the new Cat 350 hydraulic excavator for construction and industrial projects. The Cat 350 excavator can be equipped with large buckets up to 3.2 m3 (4.2 yd3). This new excavator model consumes up to 13 percent less fuel than the Cat 349. Three power mode options – Smart, Power, and Eco – match the excavator with specific jobs to further reduce fuel consumption.

“Caterpillar is committed to reducing greenhouse gas emissions, while helping our customers meet their climate-related objectives,” said Brian Abbott, Caterpillar global product manager for large hydraulic excavators. “The 350 is our latest example of delivering on that commitment.”

Excavator Technology
The new 350 excavator’s standard Cat 2D grade system indicates depth and slope on the monitor with alerts to increase handling. Grade assist helps the operator to stay on grade with single-lever digging. For truck loading and trenching applications, swing assist automatically stops excavator swing at operator-defined setpoints to consume less fuel. Lift assist helps avoid machine tipping by letting the operator know the load is within safe working range limits. To safely work around obstructions, 2D e-fence prevents the excavator from moving outside of operator-defined set points.

Cat payload onboard weighing gives real-time weight estimates to achieve precise load targets. When combined with VisionLink, the feature offers remote managing of production targets. Alternatively, the monitor’s USB port allows fleet managers to download up to 30 days of work for progress management without an internet connection or VisionLink subscription.

Available in-cab grade technology upgrades include Cat grade with advanced 2D for creating and editing grade designs via a second high-resolution touchscreen monitor and Cat grade with 3D to create and edit designs on that second monitor plus see the front linkage’s full range of motion. All Cat grade systems are compatible with radios and base stations from third-party technology suppliers.

XCMG builds on first XE7000 700 t hydraulic excavator with upgraded & optimised second unit

Leading Chinese construction and mining equipment group XCMG has announced that it has now completed manufacturing of a second XE7000 hydraulic excavator which recently rolled off the production line having had comprehensive upgrades and optimisation over the first unit.

The second 700 t hydraulic excavator it says has fully absorbed the nearly 13,000 hours of real mine experience of the first one in the Heidaigou open-pit coal mine in Inner Mongolia, which is part of the Zhungeer Complex along with Haerwusu and owned by China’s largest coal miner China Energy Corporation (CHN Energy). XCMG says the new XE7000 has a backhoe design with a larger bucket capacity and higher operating efficiency to fully meet the needs of mining customers.

It says numerous upgrades have greatly improved the operating comfort, safety and maintenance convenience of the whole machine. The platform layout is more user-friendly, and all maintenance areas can be reached through non-slip walkways, making the operation safer and the maintenance more convenient. The heat dissipation conditions of the engine compartment have been improved, the service life of the components has been increased, and overheating is no longer an obstacle to continuous work. The management of the lubrication system is more intelligent, which can complete the differentiated management of the grease category at the lubrication point, and achieve the best match of reliability and economy.

In 2018, the first 700 t super-large hydraulic excavator independently developed in China rolled off the production line. It has power equivalent to nearly 30 cars, and its bucket can shovel 60 t of material, which is close to a capacity of the train box. XCMG says China has now become the 4th country in the world with the R&D and manufacturing capacity of hydraulic excavators above 700 t – after Japan (Hitachi), Germany (Komatsu Mining Germany) and France (Liebherr).

In 2019, XE7000 was put into operation at Heidaigou, one of the largest open-pit coal mines in Asia. The average working time per day is more than 18 hours, the digging and loading equates more than 1,500 cubic metres per hour, and the availability is more than 90%.

The mine project manager said: “The work efficiency of ‘700 tons’ is very high, it is more flexible than an electric shovel, and the manipulator is also very sensitive. In addition, XCMG’s service has never let us down. The service personnel are stationed in the mine all the year round.”

Dig in tight spots with Komatsu’s new PC78US-11 compact excavator

Komatsu has introduced a new “tight tail swing” excavator well-suited for urban environments, confined spaces and crowded jobsites.

With its 68-horsepower engine, six work modes and swing radius under 5 feet, the PC78US-11 can handle precise digging, as well as large excavation tasks.

The 12-foot 2-inch boom has a greater raising angle and a short implement swing radius (6 feet 9 inches minimum), giving the PC78US-11 the ability to dig efficiently in a crowded space. At the rear, the tail swing radius measures just 4 feet 7 inches. Viewed from above, both the front and the rear corners of the superstructure are rounded, with the maximum cab extension over the tracks at just 9 inches.

Good operators like a quick machine, and Komastu’s faster boom up and swing speed increases productivity by 9%. To better match machine performance to the application, Komatsu arms the PC78US-11 with six work modes: power, economy, lifting, breaker, attachment-power, and attachment-economy.

For operators who prefer backhoe-style controls, a pattern change selector valve comes standard. The grading blade has a new moldboard profile to improve backfilling and grading efficiency. The PC78US-11 accepts buckets from 0.10 to 0.26 cubic yards.

Low maintenance demands
A new high-output 2.4-liter, Tier 4 Final engine gives you ground-level access to service points. The heavy-duty, high-pressure common rail fuel injection system and cooled exhaust gas recirculation (CEGR) achieve near complete combustion in cylinder to reduce emissions.

A Komatsu diesel oxidation catalyst removes exhaust soot and enables 100% passive regeneration without a diesel particulate filter or regular refills of diesel exhaust fluid. The no-DPF, no-DEF design translates into lower owning and operating costs, reduced maintenance and one less component to replace or worry about.

Komatsu’s compact engine makes room for a fan clutch system, allowing engine and hydraulic system tuning to reduce noise by a full decibel. Typical in-cab noise levels measure 71 decibels — about the same as a household vacuum cleaner. When engine cooling is not required, the viscous fan clutch reduces parasitic horsepower draw. Overall engine improvements boost fuel efficiency as much as 13%.
