Telescopic crawler crane

Liebherr

Telescopic crawler crane

Liebherr has developed a lightweight version of its 60-tonne LTR 1060 telescopic crawler crane – the 40-tonne LTR 1040. The LTR 1040 features significantly reduced ballast; 10 tonnes of central ballast have been taken off the chassis and a further 10 tonnes of counterweight have been removed from the slewing platform. According to Liebherr, this crane’s 40-metre telescopic boom is around 30 percent longer than the standard in this size class, which means that most jobs can be completed without a folding jib.

The LTR 1040 will hoist up to 8.6 tonnes with a radius of 10 metres throughout its entire 360-degree operating range. When it is fully raised, the lifting capacity of the 30.7-metre extended telescope is 18.8 tonnes and when fully extended, the 40-metre boom can hoist 10 tonnes. Using a 16-metre double folding jib, the LTR 1040 can achieve a maximum hoist height of 55 metres and can lift 3.1 tonnes in this configuration.

Dozer with iMC

Komatsu

Smallest dozer with iMC

Komatsu has introduced intelligent Machine Control (iMC 2.0) for its smallest dozer, the D39i-24. With iMC 2.0, operators can program 3D design data directly into the 105-hp machine, and even operators with less experience can work with efficiency. With a factory-installed, integrated system, the D39i-24 has been upgraded with a number of new intelligent features. With proactive dozing control, the dozer measures the terrain it tracks over and uses that data to plan the next pass. Tilt steering control automatically tilts the blade to maintain straight travel during rough dozing, reducing operator steering input by up to 80 percent. Lift layer control puts in repeated consistent lifts, reducing need for rework, and operators can create a temporary design surface with quick surface creation. Combined with other iMC 2.0 functions, crews can begin stripping or spreading using automated input while waiting for the finish grade model.

Factory-installed machine control Soil compactor

Dynapac

Soil compactors with cab

Dynapac CA1300/1400 soil compactors are vibratory rollers designed for compaction operations in pipe trenches, compacting roads, streets, repair work and parking lots. These 5- to 7-ton rollers come in a PD version, equipped with pads and drum drive and a D version with pad shell kit. On these rollers Dynapac has introduced a cab with fresh air ventilation, heating and air conditioning and the vibration insulated platform reduces hand/arm vibrations for the operator.

Wheeled conveyor

Terex Finlay

Wheeled conveyor

Available in either Pit or Road towable versions, the WR-80 wheeled radial stockpiling conveyor is powered via hydraulic drive plug-in as standard, enabling it to be powered by secondary equipment on site. The machine can also be configured with either electric or diesel-hydraulic drive systems. According to Terex Finlay, it can also be integrated seamlessly into stationary plants.

With a maximum discharge height of 9.95m (32 feet 7 inches) when operated in conical mode the machine will stockpile 2,313 tonnes (2,544 U.S. tons) of material. When configured to create kidney-shaped stockpiles at 270 degrees, the machine will stockpile 20,144 tonnes (22,158 U.S. tons) of material. The machine features a 22.85 m (74-foot 10-inch) discharge conveyor that has the capacity to transfer up to 300 tph (330 U.S. tph) of material.

Doosan Infracore North America

Factory-installed machine control

Doosan will offer the Trimble Earthworks Grade Control Platform for Excavators as an optional factory-installed machine control solution for the North American market. Trimble Earthworks is a grade control solution designed to make grading more accurate, faster and easier in a range of applications, including residential and commercial sites, trenches, embankments, ditches and finished slope work.

Doosan will offer a 2D machine control factory-installed option that includes a 10-inch Android tablet display running the Trimble Earthworks software application. With Trimble Earthworks, contractors can now take advantage of integrated 2D grade control with automatics for Doosan excavators, allowing operators to create smooth, flat or sloped surfaces more easily.

When the excavator is placed in Autos mode, the operator controls the stick while Trimble Earthworks controls the boom and bucket to stay on grade, reducing overcut and increasing production.
