INTRODUCTIONS & UPDATES

G-Tier excavator

John Deere Construction & Forestry

Excavators

John Deere’s seven latest excavator options available under its Performance Tiering strategy are the 135, 210, 245, 250, 300, and 345 P-Tier, all part of its mid-size range, as is the 200 G-Tier.

The high-production P-Tier machines include advanced features to improve comfort and efficiency. The new models have improved front-joint durability. Better torque retention at the clamp makes it less likely that the front hydraulic pipes will move. Redesigned boom-foot bushings offer enhanced durability for an extended machine lifespan.

The 200 G-Tier features a PowerTech 4.5-litre engine which provides optimal performance. Powerwise Plus hydraulic management uses intuitive technology to deliver on-demand power. The pilot controls are metered, helping provide reliable, fuel- efficient machine performance. Operators can push a button on the joystick and boost power or toggle automatic boom-up and lifting functions. An optional hydraulic single pedal propel system moves the machine as needed without using both hand levers and foot pedals.

Milling machine cabin

Wirtgen

Comfort cabin for milling machines

A comfort cabin is now available on the W 100 Fi – W 130 Fi milling machine models. This new cabin provides operators with a more comfortable and lower-fatigue workplace, according to Wirtgen. Control elements and assistance systems are designed to make the operator’s job easier and reduce the stress of the work. The sealed cabin reduces the operator’s exposure to noise which adds a benefit for communication; the operator is able to make hands-free calls from inside the cabin, use a radio headset with ease, or open the side window for communication with workers on the ground.

The cabin air is cleaned by a filter system and the temperature is controlled by an automatic air conditioning and heating system. The cabin is also constructed as a positive-pressure system that prevents the penetration of dirt, dust, and hazardous materials.

Excavator Machine control

Cone crusher

Terex Cedarapids Cone crusher

The CRC1350 Portable Cone Plant is paired with the TC1300X cone crusher, which at 400 hp delivers a significant increase in power over the previous version. The cone crusher is built with high efficiency roller bearings. Stroke has been increased from 45 to 70 mm, resulting in an increased throughput and improved product shape quality. It also features automated cone controls and larger closed side settings.

Features of the plant include an oversize quick-release cone feed hopper extension with an overflow chute, a 42-inch (1,070 mm) rugged straight-line product conveyor, a metal detector for off-plant feed conveyor, and service platforms with an elevated deck, guard rails, and access ladder.

Leica Geosystems

Machine control for compact excavators

Leica Geosystems’ new iCON site excavator technology is a machine control solution that enables compact excavators to carry out designs easily and accurately for trenching, grading, or moving material on a smaller scale. This solution introduces three new components: a software application, a dual GNSS receiver, and an optional communication device. The iCON site excavator application is available as standalone software or as an add-on within the existing iCON site platform. When used as an add-on, it enables a new workflow for on- and off-machine tasks, allowing construction workers to execute a variety of jobs, leveraging the same tools.

For instance, operators can use the controller unit with a Smart Antenna to stake out or create a design, then mount it in the cab to start grading according to the design. As soon as the excavation or grading to the correct design has been completed, the operator can use the same system to perform as-built checks.

Caterpillar

50-tonne excavator

Caterpillar has increased power and introduced a heavier counterweight to the new 352, enabling this hydraulic excavator to work with larger tools. This 50-tonne excavator has a maximum digging depth of up to 8,210 mm (26 feet 11 inches) and a maximum reach at ground of 12,150 mm (39 feet 10 inches), depending on configuration. Fixed or variable gauge undercarriage options are available. Variable gauge allows the undercarriage to retract to 2,390 mm (7 feet 10 inches) for easier transportation, and when expanded offers greater stability than fixed gauge.

Power is provided by the 443-hp engine. Auto dig boost increases the bucket penetration by up to 8 percent when resistance is encountered. Auto heavy lift adds 8 percent to lift capacity, and three engine modes allow operators to match power to the job.

Grade control technology is standard on the Cat 352, and can be upgraded to 3D.
