Electric-drive dozer

Caterpillar

World’s largest electric-drive dozer

The new Cat D11 XE dozer’s electric-drive system delivers constant power to the ground, continuous pushing and greater maneuverability for faster cycle times and improved fuel efficiency.

According to the company, when in production, this model will be the world’s largest, most powerful and efficient electric-drive dozer with high drive.

The D11 XE delivers up to 25 percent less fuel costs per bank cubic metre, up to 20 percent longer engine rebuild cycles than mechanical drive models, and it has 60 percent fewer moving parts. Machine protection reduces component damage for improved reliability, and updated electronics support Cat technologies including MineStar Command for dozing, which offers both remote control and semiautonomous operation.

Concrete pump

Liebherr

Concrete pump with quintuple folding boom

The new 36 XXT truck-mounted concrete pump features a new 36m quintuple folding boom, Powerbloc drive unit and semiclosed oil circuit, as well as ergonomic access steps, simplified accessibility and an expansion of stowage and storage options. An extremely compact assembly with no boom overhang at the rear ensures high maneuverability in confined spaces.

The travelling weight is approximately 26 tonnes on three axles, radio remote control enables sensitive boom movements, and the new five-piece boom delivers maximum flexibility, especially in buildings. The design and kinematics of the boom ensure minimal vibration and even work when placing concrete. Liebherr’s new Powerbloc pump drive unit has all hydraulic switching and measuring elements fully integrated. This eliminates the need for numerous hydraulic hoses and other components.

Hybrid wheel loader

Komatsu

Hybrid wheel loader for surface mining

Komatsu’s WE1850-3 hybrid wheel loader can be used for main line production and shovel backup as well as cleanup and ramp building. The SR Hybrid Drive system is fully regenerative. During braking or retarding, electrical motors become generators and feed power back into the system. According to Komatsu, this allows for up to 45 percent less fuel consumption than comparably sized mechanical drive wheel loaders or hydraulic excavators.

For faster cycle times without a corresponding increase in fuel consumption, Generation 3 series wheel loaders include the Kinetic Energy Storage System (KESS), which works in concert with the SR Hybrid Drive to store horsepower captured from braking and direct it to supplement peak power demand.

SmartGrade excavator John Deere Construction & Forestry

New SmartGrade excavator

John Deere has added the SmartGrade 470G LC excavator to its SmartGrade-equipped lineup. From digging trenches and structural foundations to shaping ditches or slopes, 3D grade control delivers precision excavation. In the cab, real-time monitoring of distance-to-grade reduces time to final grade, helping operators finish jobs quickly and accurately the first time. SmartGrade is factory installed and is calibrated from the dealer.

The excavator’s monitor utilizes a turn-and-tap rotary control for operation. Additional options include a premium high-back, thermal heat and actively cooled three-way adjustable leather seat. Other features include a single-pedal hydraulic propel system, a standard multi-language LCD monitor and rotary dial to provide access to information and functions, as well as LED lights at cab front and rear.

In addition to SmartGrade, the 470G LC model features additional precision technologies including Virtual Front, Over-Dig Protect, Virtual Ceiling, Virtual Floor, Virtual Swing and Virtual Wall.

Four grade management options are available: SmartGrade, SmartGrade-Ready with 2D, 3D Grade Guidance and 2D Grade Guidance. Upgrade kits can be installed onto equipment at a later date.

Impact crusher

Anaconda Equipment

Mid-sized impact crusher provides consistent product shape

Anaconda Equipment’s new I12-R impact crusher is a midsized plant designed to offer operators and contractors initial feed material reduction, continuous production and a consistent product shape. Engineered for both quarry and recycling applications, this crusher comes with a 43-inch-diameter (1,090 mm) 4-bar rotor on a 45-inch-wide (1,140 mm) impact chamber. The I12-R is also fitted with a large hopper area and a vibrating pan feeder with a two-tier grizzly section to help facilitate the movement of feed material toward the impact chamber, and to stop fine materials and dirt from entering the chamber.
