Compact excavator

According to Bobcat, the new E88 compact excavator delivers up to a 14 percent increase in over-the-side lift capacity when compared to the previous generation. It is equipped with dual-flange track rollers, integrated counterweight, extra machine weight and added track on ground. These undercarriage improvements offer increased over-the-side lifting and digging capacity. The Tier 4 turbocharged Bobcat engine achieves emissions compliance without the use of a DPF or SCR.

Increased distance from sprocket to idler puts more track on the ground, which adds stability and helps to prevent a rocking sensation while lifting heavier loads. Improvements to the track design increase uptime and overall life of the tracks as well.

The E88 is powered by a newly redesigned Bobcat engine that delivers efficiency and performance, plus simplified routine maintenance. It also improves cold-weather operation and includes a variety of features that make maintenance and service more convenient. The new low-effort joysticks coupled with the new hydraulic control valve offers improved metering, movement and controllability, enabling a quick, smooth and precise work group.

Screed

Ligchine’s ScreedSaver Max Plus screed features a SwingBoom pivoting frame for screed head maneuverability. This maneuverability reduces the machine movements necessary to screed a given area, which will increase speed and efficiency while maintaining accuracy. The pivoting boom enables up to 5 feet, 3 inches (1.6 m) of side-to-side screed head movement. Screed head length is 10 feet (3 m) and boom extension 17 feet (5.18 m).

Other new features include a built-in diagnostic touchscreen, a redesigned wireless remote control system, a Honda gasoline engine and Topcon laser receivers. Topcon’s 2D Laser Leveling is standard for grade, slope and dual slope levelling. Topcon 3D Systems is optional for contoured concrete paving.

The new Cat D4 (formerly D6K2) weighs in at 29,259 pounds (13,272 kg), with a net power of 130 hp (97 kW). The D4 LGP (low ground pressure) has an operating weight of 30,882 pounds (14,008 kg). A lower sloping hood line provides up to 30 percent better visibility to the area in front of the blade. The shorter sight lines mean the visual distance between the blade and the material pile is shortened by about 40 percent.

Standard technology features include Slope Indicate, Stable Blade and Traction Control. Optional technology features include Cat Grade with Slope Assist, Factory Attachment Ready Option (ARO) and factory integrated Cat Grade with 3D.

Additionally, 3D grade systems from Trimble, Topcon and Leica can be easily integrated with existing grading technology infrastructures. All Cat Grade systems are compatible with Trimble, Topcon and Leica radios and base stations.

DTH hammers

Epiroc M-series DTH hammers are designed for maximum drill speed and productivity on SmartROC D65 machines. Models include the COP M6, COP M7 and COP M8. Pairing the SmartROC D65 with Epiroc’s COP M6 DTH hammer in LowFlow (LF) mode capitalizes on the higher pressure available for better penetration rates. The M6 hammer is capable of operating at 425 psi (30 bar). Matching the M6 hammer’s airflow cylinder to the compressor configuration of the D65 ensures maximum performance and drilling efficiency.

M-series hammers are designed to adapt to different air pressures and volumes with a simple component exchange. The two-in-one feature makes M-series hammers compatible with a variety of Epiroc or competitive drill rigs operating at most altitudes in nearly any climate. For drills like the Epiroc DM45, or other machines delivering greater cfm but a lower psi compressor package, like a 1070/350 airend, the M6 DTH hammer with the HighFlow (HF) configuration is able to maximize use of the extra air volume.

All-terrain crane

With its AC 4.070-1 and AC 4.070L-1, Tadano is introducing an upgraded four-axle all-terrain crane with a lifting capacity of 75 USt and two boom lengths. It features a new carrier cab, a multifunctional crane control system and Stage V engines. With a length of 171 feet, the six-section main boom can lift 12,786 pounds at full length. Tadano says it improved the lifting capacity for steep main boom positions with small radii. A 144-foot main boom is available.

The AML-F crane control system makes set-up times quick and ensures a high degree of flexibility for positioning the crane thanks to asymmetrical outrigger setting capabilities. The automatic lifting capacity selection makes the job easier for crane operators. The crane selects the optimal extension sequence for each radius by itself. In addition, the Tadano Lift Adjuster provides greater convenience during lifting and lowering by reliably reducing load swinging.
