The new Cat 336 hydraulic excavator features three engine modes that match excavator power to the demands of the job while saving fuel. Power mode delivers power to meet tougher tasks and Smart mode automatically matches engine and hydraulic power to digging conditions to lower fuel consumption. Reducing engine speed to a constant 1,500 rpm, Eco mode minimizes fuel consumption. High-ambient temperature capability of 52 degrees Celsius (125 degrees F), cold-start capability at -18 degrees C (0 degrees F), and the ability to work at up to 4,500 metres (14,764 feet) above sea level enables the 336 to work in various climates. Optional Cat Stick Steer makes travel and turning easier, and standard technologies include Cat Payload on-board weighing, Grade Assist for maintaining grade, and 2D Grade with depth and slope indication.

Vibratory compactor

Ammann says that the battery-powered eAPX 68/95 3D vibratory compactor is the first vibratory plate on the market that can go in an arc, circle, or turn on the spot. It has a low operating height of 700 mm and is ideal for trench applications – including those with support systems and cross braces. A remote-control unit provides the eAPX 68/95’s precise movements and the operator can easily steer the eAPX 68/95 along straight lines or in hard-to-reach spots from a distance. Four battery-powered electric motors enable the machine to work in applications off-limits to combustible engines, including indoors and in enclosed spaces. The plate can run continuously for approximately 80 minutes before a 30-minute recharging is needed. The drive requires minimal maintenance as it has no hydraulics, operating fluids, or gears.

RC tiltrotator

Rototilt Control is a new series of tiltrotators, control system, and app for remote support. The display for the RC system has been redesigned with a new touchscreen that allows the user to operate the SecureLock safety lock directly in the display with just two presses of a button. The upgraded tiltrotators will be available for owners of excavators weighing between 10 and 43 tonnes. Rototilt has improved energy and fuel efficiency with pressure-compensating hydraulics in the tiltrotators and these tiltrotators meet the Open-S hydraulic interface standard. Customers who choose an RC tiltrotator without the QuickChange fully automatic quick coupler system will now have the ability to retrofit at a later date.

Takeuchi new-generation TB335R short tail swing compact excavator delivers a rear overhang of only 3.1 inches over the tracks, making it ideal for working in tight or confined spaces. The cab model has an operating weight of 8,310 pounds (3,770 kgs.), a maximum bucket breakout force of 9,127 pounds (40.6 kN), and a maximum arm digging force of 4,290 pounds (19.1 kN). The excavator is powered by an EPA Tier 4 Final engine delivering 24.4 hp (18.2 kW) and a maximum torque of 70.6 ft.-lbs. (95.8 Nm). Two work modes – Standard and ECO – allow operators to match the mode to the task at hand, choosing more power or fuel savings as desired. The TB335R’s cab includes a 7.0-inch touchscreen, multi-function colour display. Canopy models offer a 4.3-inch, high-definition, multi-function display. Both cab and canopy models have low-effort, pilot-operated joystick controls.

Komatsu’s rigid frame off-highway haul truck, the HD15008E0, is built for mining, quarry, and aggregate applications. The machine can handle 150 U.S. tons of material and features a 1,580 gross horsepower (1,180 kW), Tier 4 Final Komatsu SDA16V159E-3 engine. The redesigned cab, combined with a MacPherson strut-type and hydropneumatic suspension, gives operators a smooth ride. It is equipped with hydraulic, wet multiple-disc brakes on all four corners. The continuously cooled, large-capacity brakes also act as a responsive retarder. Downhill descent can also be controlled by setting a desired travel speed with the automatic retard speed control. With a tight turning radius (36 feet 9 inches), operators can maneuver in and out of close quarters. The truck has a seven-speed, fully automatic transmission with two configurable reverse speeds. Komatsu’s advanced transmission with an ideal modulation control system provides electronic shift control with automatic clutch modulation, delivering optimized clutch engagement at every gear.
