Manitowoc introduces New Crawler Cranes with Breakthrough Variable Position Counterweight (VPC)
The VPC system automatically positions the counterweight to fit the required lift. The counterweight moves along the rotating bed and is automatically positioned based on changes in boom angle. Advantages for customers include reduced ground preparation, lower ground-bearing pressure and less counterweight, without sacrificing capacity. Customers will not have to buy, transport or install as much counterweight compared with a traditional configuration. The counterweight boxes are also designed to be common across multiple crane platforms.
"The VPC is game-changing technology," said John Kennedy, SVP crawler cranes. "This new technology will have a significant impact on the lifting industry, as it enhances crane capacities, reduces mobilization time on the job site, and in the end, saves customers a significant amount of time and money."
The MLC300 features 96 m (315 ft) of boom and has the option of a fixed jib attachment of 30 m (98 ft). A 96 m (315 ft) luffing jib can be added to extend its reach to 144 m (473 ft). The MLC650 has a 104 m (341 ft) main boom to which a 30 m (98 ft) fixed jib can be added. A 101 m (331 ft) luffing jib can be added to reach a maximum 157 m (515 ft).
Both cranes are ideal for energy-related projects, including refineries, petrochemical installations, and power plants, as well as infrastructure applications. The smaller footprint plus the Variable Position Counterweight system enable the cranes to easily move around a job site, and a VPC-MAX capacity enhancing attachment allows increased capacity for heavy lifts that would usually require a wheeled-type lift enhancer.
The VPC-MAX attachment increases capacity and boom and jib combination lengths. The counterweight movement is based on the lifted load, boom length, boom and jib length, and load radius. The MLC300 can raise 120 m (394 ft) of boom with the VPC-MAX attachment and a boom and luffing jib combination of 168 m (551 ft). The MLC650 can raise 140 m (459 ft) of boom with the VPC-MAX attachment and a boom and luffing jib combination of 205 m (672 ft). The MLC650 maximum capacity increases to 700 t (770 USt) with the VPC-MAX installed.
For the MLC300, the VPC-MAX attachment increases the max load moment when a 30 m (100 ft) fixed mast, a VPC-MAX counterweight beam and an additional 40,000 kg (88,185lb) of counterweight is added to the base crane. The ground preparation area needed for the MLC300 using the VPC-MAX can be only one-tenth of that required by competitive cranes.
For the MLC650, the VPC-MAX attachment increases the max load moment when a 36 m (118 ft) fixed-mast VPC-MAX counterweight beam and an additional 100,000 kg(220,460 lb) of counterweight is added to the base crane.
Because the counterweight attachment of the VPC-MAX on the MLC300 and the MLC650 never touches the ground, higher capacity lifts on barges that customers were never able to perform before are now possible. In addition, with its long reach and high capacity, the MLC650 can install 120 m (394 ft) and taller towers for the wind industry.
Both the MLC300 and MLC650 are designed to be easily transported anywhere in the world with their optimized component weights and dimensions. They have a removable live mast shipping module and their boom inserts are designed to allow luffing jib inserts to ship within them, which reduces shipping costs. In addition, both cranes use Manitowoc's patented FACT connection technology and are operated via Manitowoc's Crane Control System (CCS), a standard operating system across several crane models in different product ranges.
Additionally, the MLC300 comes with a crawler tensioning system, a dedicated hydraulically activated cylinder and hydraulic supply that allows independent track tension adjustment via crane setup remote and standard hydraulic connection.
"For both the MLC300 and the MLC650, we interviewed customers around the world," said Kennedy adding that "The result is two innovative cranes that are geared toward their needs. Customers will be able to lift heavier loads to higher reaches, reduce the time spent preparing the site for lifts, and ultimately, save money. The VPC's breakthrough technology will help customers become more dynamic and nimble on the job than once thought possible."
Liebherr Unveils it New LTM 1160-5.2 Five-axle Mobile Crane
Powerful boom system
The six-part 62 m long telescopic boom on the new LTM 1160-5.2 is telescoping in and out easily via the tried and tested rapid action TELEMATIK telescoping system. With its 10.8 m to 19 m folding jib and additional telescopic boom extensions, the new 160-tonner can achieve hoist heights of up to 93 m and outreaches of up to 76 m. The folding jib can be erected to an angle of 0°, 20° or 40°. An optional hydraulic adjustment facility for the folding jib is available, enabling it to luff under full load between 0° and 40°. For work in two hook operation, a second hoist gear and a 2.9 massembly jib and a rooster sheave is available.
The maximum ballast of the new LTM 1160-5.2 is 54 t with a width of 4.27 m. The base plate with 10 t and a 4 t ballast plate have the same width as the vehicle.
With a total weight of 60 tand a 12 taxle load, the new crane can carry its double folding jib, a 3-sheave hook block and a storage box with a generous payload.
Ease of control with Load Sensing and LICCON2
In the hydraulic system, the electric "Load-Sensing" control ensures accurate work operations. Up to four movements can be actuated simultaneously. Depending on the requirements for the lifting task and of the crane driver, the slewing gear can be easily switched from "open" to "hydraulicallylocked".
The Liebherr LICCON2 crane control is used in the LTM 1160-5.2. Thanks to its modern and future-oriented control architecture, it facilitates adaptation to the continually growing needs of the market. A mobile, multifunctional control and display unit – BTT Bluetooth Terminal –is provided for setup functions. This means that the crane can be supported easily and safely. The crane driver also has the option of attaching and removing the hook block on the crane bumper with visual contact via remote control of the hoist winch and the luffing cylinder of the telescopic boom.
The Liebherr LICCON2 mobile crane control also offers the option of simple and thus cost-effective extension into a complete remote control system for the crane. Other than the relevant software on the crane, all that is required is a console with two master switches, which the existing BTT plugs into. A significant advantage for the crane operator is that the console can also be used for other cranes with LICCON2 controls programmed for remote control operation.
Innovative single-engine concept
The LTM 1160-5.2 features the new Liebherr concept for powering the superstructure. Instead of the twin-engine concept normally used on cranes in this class the 160-tonner is powered by a single engine with a mechanical shaft. Gear shafts are routed from the distributor gear in the crane chassis via two mitre gears through the centre of the slewing ring to the pump distributor gear in the superstructure.
A mechanical shaft ensures a particularly high efficiency level and low engine speeds in the chassis engine provide sufficient power for crane work. This ensures the economy of the new concept in terms of fuel consumption. The benefits of omitting a separate superstructure engine include a reduction in the amount of maintenance work and a reduction in weight. The omitted weight can be used for load-bearing components, thus increasing the crane's load capacity.
An add-on program has been developed for the new crane drive concept with just one engine and a mechanical shaft to allow the machine to be run with low fuel consumption. This enables the complete pump drive to be disconnected automatically when the engine is idling and then reconnected by the intelligent controller in a matter of seconds when it is required.
Time-tested, powerful drive train
A six-cylinder Liebherr diesel engine which develops 400kW / 544h.p. at 1900 rpm and torque of 2,516 Nm at 1350 rpm provides the LTM 1160-5.2 with all the power it needs. The engine complies with the emission regulations of Directive 97/68/EC - Stage 4 and Regulation EPA/CARB – Tier 4 final in the USA.
The force is transferred to the crane axles via the 12-speed ZF-AS Tronic gears. The intarder, a zero wear hydrodynamic brake integrated in the gearbox, acts as a retarder. In addition a Telma eddy current brake is available as an option. Like almost all LTM mobile crane models today, the LTM 1160-5.2 features pneumatic disc brakes. The rear axles of the new 160-tonner have active electro-hydraulic steering depending on the vehicle speed. This increases the manoeuvrability of the vehicle and drastically reduces tyre wear. Five steering programmes can be selected conveniently at the touch of a button.
Linden Comansa LC 2100 Series Attract Global Attention
"We experienced over twice the activity of the last show," says Bill Carbeau, Vice President of Business Development for Linden Comansa America. "The visitors had high interest and were ready to talk about purchases or equipment purchase plans. Over 60% were qualified candidates with over half of those requesting information and quotations."
"Our theme was to generate awareness and educate the potential owner of the benefits of the Linden Comansa product range. About 25% of inquiries were related to the luffing-jib crane family, while about 75% related to various sizes of the highly acclaimed flat top tower cranes. Although no orders were written at the show, we received requests for quotes totaling over 30 tower cranes. We are confident that it will not comply with the phrase "what happens in Las Vegas stays in Las Vegas" and that the show will be a precursor to a great year for sales."
According to Martín Echevarría, Linden Comansa's Sales Director, the ConExpo fair has been much better than expected: "We knew that the North American market was improving, but we were pleasantly surprised with the atmosphere so optimistic and the number of new projects that are coming out. We have been very busy during the entire fair, preparing offers and making new contacts which we hope will be fruitful in the upcoming weeks."
The Las Vegas Convention Center has also served to bring together many dealers of Linden Comansa, who came mainly from the Americas, Europe and the Middle East: Canada, Colombia, Chile, Brazil, Germany, Sweden, United Arab Emirates, etc. Along with them were also present at ConExpo many final customers and rental companies that use Linden Comansa cranes in their projects.
CASE Showcases New Innovative Products
The CX350D offers significant advances in power, fuel savings, operation and control featuring an innovative combination of cooled exhaust gas recirculation (CEGR), selective catalytic reduction (SCR) and diesel oxidation catalyst (DOC) technologies, which helps maximize uptime and performance.
CASE Construction Equipment has equipped each model of 821 F and 921 F Wheel Loader with a selective catalytic reduction (SCR)-only solution that treats emissions separately with Diesel Exhaust Fluid (DEF) and does not require the engine to re-circulate exhaust gas. This optimizes combustion and machine performance, lowers engine temperatures, and eliminates maintenance and downtime associated with filter replacement and regeneration. It also helps lower fuel consumption.
"CASE was the first to implement SCR into our Tier 4 Interim machines because that solution makes the most sense for wheel loaders based on the inconsistent engine loads placed on the machine through its regular work cycle," says Philippe Bisson, brand marketing manager, CASE Construction Equipment.
Each new Tier 4 Final wheel loader delivers best-in-class horsepower with a 6.7-liter Tier 4 Final-certified engine that also provides quick throttle response and impressive torque. The 821F and 921F wheel loaders produce 212 and 241 net peak horsepower (158 and 180 kW), respectively.
To provide operator comfort and help boost productivity, the 821F and 921F wheel loaders feature a cab with full climate control, as well as an award-winning joystick steering option, and equipped with two-level hydraulic control system.
The M Series Dozers displayed at CONEXPO included five models ranging from 92 to 214 net horsepower. It uses highly-efficient hydrostatic transmissions to deliver a class-leading drawbar pull. The new M–series Dozer is powered by a fuel efficient FPT Industrial engine which allows fuel savings up to 14%. This is the first time that selective catalytic reduction (SCR) technology is built into a Case dozer.
The new CASE M–Series Dozer was fully launched in the North American markets by March 2014. In other regions where the company operates, models will be introduced with different timing and in line with different market's emission requirements. Case Construction Equipment is now all set to introduce the new product range with Tier 4 norms in India once it is implemented.
