INTRODUCTIONS & UPDATES

EC550E EXCAVATOR

Volvo Construction Equipment

50-ton-class excavators for mass excavation

The new EC530E and EC550E excavators are made for heavy-duty digging, mass excavation and large-scale site preparation. When coupled with large buckets, these excavators are designed to efficiently fill articulated haulers in the 30- to 40-ton class.

These excavators feature a super-rigid reinforced undercarriage, which provides durability and strength. This is supported by equally sturdy lower and upper frames. The EC550E undercarriage has a long and wide lower frame, giving it extra stability when working with heavier loads. The boom and arm on both machines features a larger pin size for added strength.

The electro-hydraulic system contributes to a 25 percent improvement in fuel efficiency with its Independent Metering Valve Technology that, due to intelligent electronic control, offers more precise operation and efficiency than a traditional mechanically coupled hydraulic system, according to Volvo. Engine pump optimization lowers engine speed while maintaining power.

The EC530E and EC550E offer high levels of control and efficiency, including creep mode for precise lift-and-carry work and optional Comfort Drive Control which helps reduce operator fatigue by allowing the excavator to be steered with joystick rollers instead of pedals.

Operators can also select functions like boom/swing and boom/travel priority, which enables one function to take the lead over another. The boom-down speed can also be adjusted, giving optimum control for tasks that require extra precision. New boom-and-arm bounce reduction technology lessens machine shock.

MOBILE CONE CRUSHER

Kleemann

Mobile cone crusher

The MOBICONE MCO 90(i) EVO2 mobile cone crusher delivers a maximum feed capacity of up to 270 tph, is powered by diesel-direct drive and is simple to transport, according to Kleemann. The conveyor belts are driven electrically, and the continuous feed system uses a probe to monitor the crusher level and regulates the material supply for the optimum volume.

The cone crusher covers a wide gap range of 6 to 45 mm for flexibility. All crushing gap widths are set conveniently via the radio remote control. Equipped with an intelligent overload system, Kleemann says that safety and stable processes can be guaranteed even under difficult conditions.

The tramp release system provides protection from uncrushable materials, such as wood or metal. The software-supported overload system has two modes that give users a choice of whether to focus more on product quality or product volume.

Caterpillar

Mini excavators

The new 2.7- to 3.5-tonne 302.7 CR, 303 CR and 303.5 CR hydraulic mini excavators feature stick steer, cruise control, operator adjustable settings and tilt-up canopy or cab as standard. According to Caterpillar, design changes to the machines in this size class deliver up to 10 percent more performance in travel and trenching over previous models. Hydraulic system upgrades improve lifting performance and cycle times.

These mini excavators feature a compact radius swing, and an expandable undercarriage option is available for the 302.7 CR. Interchangeable counterweight packages are also available. All three models offer both standard- and long-stick configurations. Standard digging depths range from 96.5 to 110.6 inches (2,450 to 2,810 mm), while the long stick configuration delivers reach from 104.3- to 122.4-inch (2,650- to 3,110-mm) depths. A dozer blade comes as standard and an angle blade option is available on the 303.5 CR.

MINI EXCAVATOR

LIGHT TANDEM ROLLER

Ammann

Light tandem rollers

Ammann says its new series of light tandem rollers are easy to operate, transport and maintain. The rollers retain their ability to work in-line or off-set, enabling compaction against curbs and other obstructions. The new double drum rollers are the ARX 12-2, ARX 16-2 and ARX 20-2. The combination ARX 16-2C roller utilizes a steel drum in front and pneumatic tires in the rear for higher machine traction and improved sealing of surfaces. A new vibratory circuit setting delivers expanded vibratory frequencies that facilitate quicker compaction.

Operators can now effortlessly switch between drive modes; in previous generations, this required a service technician. Soft drive enables smooth, steady adjustments to directional changes. Hard drive responds quickly to directional changes. Panic stop idles the machine if the operator makes very sudden directional changes or significantly adjusts the travel lever position.

TELEHANDLER

Xtreme Manufacturing

World’s tallest fixed boom telehandler

The new Xtreme XR1585-C delivers a maximum lift height of 85 feet (25.9m) and is the first Xtreme telehandler to utilize a five-section boom design. Capable of lifting loads weighing up to 15,000 pounds (5,443 kg), the Xtreme XR1585-C delivers a 67-foot (20.4 m) maximum forward reach and is available with a choice of fixed, fork positioning, swing or side tilt C-class carriages.

Weighing 65,500 pounds (29,710 kg), the Xtreme XR1585-C is powered by a 4.5 L Cummins 173-hp Tier 4 Final diesel engine and features a large-capacity 100-gallon (272.5 L) fuel tank. Utilizing a newly designed chassis, specific to this model, the XR1585-C is 102 inches (2.6 m) wide, has a stowed height of 10 feet 1 inch (2.7 m), and a turning radius of 16 feet 8 inches (4.8 m), and has wide stance outriggers as standard for maximum stability. A B-class carriage version, the XR1285-B, is available with a reduced 12,000 pounds maximum capacity.
