Volvo claims world’s first artic full suspension
Automatic leveling and stability control on all four wheels leads the list of design features on Volvo Construction Equipment’s E-Series articulated trucks. Volvo says this full suspension allows these haulers to travel at much higher speeds (around 34 mph) – with or without a load – plus float over rough ground without bouncing and rolling. Instead of traditional rubber suspension, the E Series suspension has a hydraulic cylinder fitted to each wheel. The system, offered on the A35E and A40E models, constantly monitors the load and ground conditions, adapting the suspension to suit prevailing conditions. (You’ll still be able to get an updated traditional suspension in the E-Series models.)

Lift up to 600 feet
Godwin’s Dri-Prime product line now has three additional HL Series pumps: the HL110M, HL130M and HL160M extreme high-lift models. The pumps have a single-stage impeller design that offers lifts up to 600 feet and solids handling capability to 1 3⁄8 inches. The automatic self-priming pumps have run dry capability.

Wacker enters U.S. compact wheel loader market
Wacker introduced six compact wheel loader models at Bauma, and will debut several of these gradually in the States. One model is the pictured WL 18, featuring a narrow 41.5-inch-width and inside turning radius of 43.5 inches, dimensions that allow it to maneuver tight jobsites. With a maximum dump height of 81 inches, the model also features a hydraulic lifting capacity of 4,145 pounds.

Hydraulics, engines central to Cat track loader upgrades
Caterpillar’s 953D and 963D track loaders offer several enhancements over their C-Series predecessor machines, including more powerful fuel efficient engines, a load-sensing hydraulic implement system and electro-hydraulic implement controls. The Cat C6.6 ACERT engine in these machines deliver 15 percent more power at 148 horsepower in the 953D and 25 percent more power at 189 horsepower in the 963D. The load-sensing electro-hydraulic implement system provides only the required flow to the work tool and lift arms, allowing more power for the tracks when needed and increasing fuel efficiency. Choose between a joystick or two-lever controls to operate the bucket lift and dump functions.

JCB excavators decrease fuel consumption by 12 percent
JCB launched its newest JS Auto tracked and wheeled excavators, which offer up to 25-percent increase in power, up to 27-percent increase in torque and a 12-percent decrease in fuel consumption. Also reduced is engine noise, decreasing by 5 decibels. An isochronous engine governor system reacts to hydraulic requirements and automatically adjusts engine power to the job at hand. A high-backed seat is now standard, and a cargo shelf and stowage net offer improved storage.

Liebherr ups working speeds, cab space on 32-metric-ton excavator
The R 934 C Litronic excavator from Liebherr, weighing 32 metric tons, has a four-cylinder, 203-horsepower engine operating at 1,800 rpm. The machine’s electronic maximum-load control ensures efficient transformation of engine power into hydraulic performance, resulting in greater breakout forces and higher working speeds than its predecessor, the R 934 B. The cab also offers 10 percent more space than the previous model. A Regeneration Plus function enables the boom to be lowered without additional pumping energy.

Teaser crane becomes reality
After sneak peeks a few months ago (see Equipment World, November 2006), Manitowoc unveiled its Grove GTK1100 with its distinctive vertical telescopic mast. The 251-foot mast, mounted to an upperworks, creates a crane that can reach heights of more than 459 feet. The mast is topped with a five-section, 196-foot telescopic boom. The GTK’s primary carrier is based on a standard semi-trailer; only a 200-metric-ton all-terrain crane needs to assist this crane’s set up. With a relatively small footprint, the crane can perform jobs where loads are lifted to tall heights or where set-up space is limited, including maintenance and erection of wind turbines, erected cell phone towers, placing air conditioning units on high-rise buildings and work in power plants and refineries.

Economizer Compaction Sensor provides continuous feedback
The BPR65/70D reversible plate compactor from Bomag now has an Economizer compaction measurement system. The system – which consists of a vibration sensor with a computing and display unit – provides continuous feedback of compaction results by means of an LED display on the engine hood. The display indicates the level of compaction achieved and highlights any soft spots in the material.

Dooson expands heavy line up
Dooson Infracore introduced three crawler excavators, three wheeled excavators and two wheel loaders at the show. The DX series of crawler excavators (DX180, DX225 and DX255), the DX series of wheel excavators (DX140W, DX190W and DX210W) and the DL series of wheel loaders (DL200 and DL250) offer an electronic package that allows communication between the engine and hydraulics for performance and fuel economy. Other excavator model features include a boom overload warning device, CD player, travel and swing alarm and an auxiliary valve with one-way and two-way hydraulic piping to the end of the arm with flow control inside the cab.

New engines improve horsepower, torque
Perkins has upgraded its line of medium-duty 800C engines with the debut of its 800D models. These 3.3-liter, 63- to 83-horsepower engines boast a 4-percent increase in power and 5-percent increase in torque rise over the models they replace. Available in both turbocharged and naturally aspirated designs, the 800D engines have also cut noise levels by 5 percent thanks to quieter combustion, a redesigned gear train and a stiffer timing case. The engines’ package size and hook-up points remain identical to previous models, and 500-hour service intervals are standard.

Service wear parts in the field
Ingersoll Rand has introduced a new heavy hydraulic breaker, the Tramac V2500, for carriers in the 60,000- to 88,000-pound range. All the main wear parts, including a new one-piece bushing, are field replaceable and don’t require you to remove the breaker from the carrier or remove tie rods. The V2500 has an operating weight of 5,555 pounds, hydraulic pressure of 2,248 psi and a flow range of 46 to 66 gallons per minute. This gives the big breaker an energy impact rating of 7,500 foot pounds and 300 to 500 blows per minute using a tool diameter of 6.3 inches.

View and work real time digital data from the cab of your truck
To simplify operations and increase efficiency in the field, the new Trimble Site Controller Software Tablet Edition extends the use of Trimble site positioning systems to jobsite supervisors, foremen and project managers. From the convenience of their trucks or vehicles they can see real-time cut-and-fill displays, conduct site prep and checking, set up GPS base stations and view and edit designs. The Site Controller Software Tablet Edition works with the Trimble site positioning product family including its GPS and total station systems.

System ties all elements of digital earthmoving together
A digitally-savvy contractor may have GPS earthmoving systems running his machines, wireless asset management systems monitoring the mechanical health and whereabouts of his machines plus office software to organize and sort all this information. Topcon has introduced a jobsite management system called SiteLINK that ties all these streams of digital data into one interconnected display. The system provides information in real time to anybody connected to the system, whether in the field or the office, and works on any machine brand. SiteLINK allows equipment operators or supervisors in their trucks to see just what each machine on a site is doing at that moment. And all the information can be collected, organized and analyzed to help make better decisions about equipment utilization, maintenance needs and productivity.
