LinkBelt reveals TCC-500 crawler crane at ConExpo

Link-Belt Construction Equipment is showing its seriousness about growing its share of the market for telescopic crawlers. The company will get a lot of attention with its latest offering in the tele crawler line, the all-new 50 US ton (45 metric ton) capacity TCC-500, which has already been built and tested at the Lexington plant and will be shown at ConExpo in Las Vegas in March.

It is the third crane in Link-Belt’s tele crawler line and it’s a solid piece of equipment that will engage companies in the power utility industry, especially, the manufacturer said. Link-Belt is telling its distributors about the new crane. Shipping to customers is expected to start by early March.

“We think this crane will get a lot of attention from the utility market,” said Pat Collins, product marketing director. “It has a 110-foot [33.5 meter], full-power boom and 50 tons of capacity, which is more in line with what the utility market is looking for. It’s also been designed for ease of transport. We’ve engineered it to hit the weight targets so transportability is easy and efficient.”

Collins said the TCC-500 “gives customers a second option below our TCC-750 for less demanding and/or more cost-sensitive jobs. It’s simple to operate, tough and rugged.”

And the bells and whistles are aplenty, from audible and visual alert systems to rear and winch view camera systems.

The TCC-500 offers an impressive capacity chart that rivals lattice crawler cranes with a similar base rating. The four-section, full-power boom on the TCC-500 is 35 feet, 6 inches to 110 feet in length with box-type construction of high tensile steel consisting of one base section and three telescoping sections. The vertical side plates of the boom have diamond-shaped steel impressions for a higher strength to weight ratio. Fly jib options include a 28.5 to 51 feet (8.7 to 15.5 meter), two piece bi-fold lattice fly, stowable, offsettable to 2, 20 and 40 degrees; maximum tip height is 165.5 feet (50 meters).

Link-Belt has designed the TCC-500 to move quickly and easily on or off the jobsite. With a standard counterweight package of 25,000 pounds (11 metric tons), the TCC-500 transports in just one load while staying under 100,000 pounds (45 metric tons) in most cases. On the trailer, the TCC-500 travels at a height of 9 feet, 10.55 inches (3 meters) and a width of 11 feet, 5.24 inches (3.5 meters).

For flexibility on the jobsite, a hydraulic cylinder mounted in the lower frame hydraulically extends and retracts the all-welded, machined steel track frames. The TCC-500 can work at three track widths: 15 feet, 2.37 inches (4.6 meters) fully extended; 13 feet, 6.11 inches (4.1 meters) intermediate; and 11 feet, 5.24 inches (3.5 meters) retracted. It has two travel speeds and can travel up to 2 miles per hour (3.2 km/h) to spend less time traveling and more time lifting.

A Tier IV final Cummins QSL engine powers the TCC-500, producing 215 hp and driving a variable displacement piston pump package. Simple and dependable hydraulic pilot-operated control valves distribute flow to all functions, the company said.

Other features include available boom-mounted 360 degree floodlight, swing audible and visual alert alarm with swing stop system, wind speed indicator, drum rotational and directional indicators and upper guard rails. It also has pole claw, earth auger and man basket attachments.

“The TCC-500 is an excellent general contractor crane, and its moneymaking potential is huge,” Collins said. Link-Belt has also developed an export version of the crane with a Tier II Cummins engine.

“We feel really good about this crane, and we are excited to show it off at ConExpo,” Collins said.

Terex CC2800 crawler crane slips in Singapore

A 600 tonne crawler crane slipped off a truck yesterday, while being loaded in Singapore, fortunately no one was hurt in the incident.

The crane a Terex CC2800 owned and operated by local heavy lift and crane rental company Yew Choon. It had just finished work at the new National Stadium in the Kallang area of Singpaore, where it had been helping install the stadium roof structure.

It looks as though the slew lock was not activated and that the superstructure swung over the side as the loading jacks were retracted which probably caused the trailer to list to one side. The Ministry of Manpower (MOM) was informed of the incident and is expected to investigate.

Fatal crane incident india

One man died and another was injured when a crawler crane overturned at a metro construction site in Saidapet, Chennai, India on Saturday.

The crane was said to be lifting a 25 tonne counterweight and was slewing to load it onto a trailer when it overturned. The boom landed on welder Ranjith Biswal, 20, killing him outright, while Tira Nayak, 19, was trapped by his leg and was taken to hospital with a serious fracture which has resulted in the leg being amputated.

Work has been suspended while an investigation looks into the cause for the incident, the crane operator aged 34, has been charged along with the crane supervisor. The contractor involved is Gammon, which has said that the crane was in good working order and that it is co-operating with the investigation.

India’s metro construction programme has seen numerous fatal crane incidents in Delhi, Bangalore and only last year a similar incident occurred in Chennai, when a man was killed and six injured after a crawler crane dropped its load.

SANY America introduces 550 ton crawler crane SCC8500

SANY America’s new 550 U.S. ton crawler crane will satisfy a niche between 440- and 660-ton machines and is ideally suited for construction of wind energy towers, fossil fuel plants, nuclear facilities, petrochemical installations and a variety of infrastructure projects. The SANY SCC8500 has a host of exclusive and in-demand features to meet the needs of customers in a range of applications. It was first displayed at the Bauma China trade show in late November.

“Customers told us the 500-ton machine is badly needed to fill a niche between existing machine sizes,” said John Lanning, global director of research and development for SANY crawler cranes. “The 400-ton-class machines are too small to handle bigger nacelles in wind construction, and the 600-ton cranes require a back mast and luffing jib to make these lifts. The SCC8500 is the perfect solution.”

The SCC8500 is especially well-suited for construction of 330-foot (100 m) wind towers and placing 2.5-megawatt nacelles. The SCC8500 can do these lifts with a straight boom and an offset wind tip, with no need for a back mast. With a full complement of attachments and options, including fixed jib, luffing jib and the SANY UltraLift package, the SCC8500 is a great solution for construction of nuclear, petrochemical and wind power; and on infrastructure projects such as bridges, waterways, dams and sewage-treatment plants.

“The SCC8500 has lighter overall weight, transports like a 400-ton machine and can be quickly assembled and mobilized on the job site,” Lanning said. “These features, along with the lift of a 500 ton machine put the SCC8500 in a class by itself.”

ACE System Delivers Auto Counterbalance

The SANY-exclusive ACE (auto counterbalance equalization) System senses the boom angle and uses hydraulic cylinders to automatically adjust the position of the movable upperworks counterweight. The standard ACE System has one upperworks tray with hanging brackets and 20 upper sideblocks for 478,404 pounds (217 000 kg) of counterweight. The ACE System design avoids an inefficient carbody counterweight and keeps overall crane weight down. The base machine transports on 21 trucks, the same as a standard 440-ton crane. With the ACE System, the SCC8500 doesn’t need a counterweight wagon, making it much more mobile on the job site.

The optional UltraLift package includes a second counterweight tray with hanging brackets and 36 upper sideblocks for 868,621 pounds (394 000 kg) of counterweight. A second pair of hydraulic cylinders extends the counterweight beam to 52 feet 6 inches (16 m). The counterweight beam is supported by a back mast in the UltraLift configuration.

“The beauty of this design is you get more than 500-ton performance in a machine that transports as easily as a 400-ton crane,” Lanning said. “Contractors will value the quick set up and mobilization of the SANY SCC8500.”

Sleek UltraCab Puts the Operator First

The SANY-exclusive UltraCab puts a premium on operator performance and comfort. The sleek lines of the cab’s exterior reflect the operator-friendly features inside. Styled by the Porsche Design Studios, the cab has a wide field of reinforced glass for commanding views of the load and the job site. The cab’s steel frame has overhead structural plates for added security. Cab air-conditioning and heating is powered by an auxiliary diesel generator. The UltraCab tilts up 20 degrees for optimum visibility. The large, high-resolution display shows crane gravity and many other monitoring statistics in real time.

“During long wait periods on the job site, the operator can shut down the crane engine and maintain a comfortable cab thanks to the dedicated diesel generator,” Lanning said. “For extra versatility, the generator can also power the engine and reservoir heaters during overnight cold-weather shutdown.”

The proprietary SANY load moment indicator automatically detects lifting capacity, boom angle, top height and radius to ensure reliable operation. A closed-circuit television system gives the operator views of all winches, the counterweight and job-site surroundings. An anemometer on the boom tip monitors wind speed and transmits the data to the in-cab monitor. An electronic level indicator displays data on levelness of the crane. Ground pressure can also be displayed on the control panel.

Pressure-compensated drive motors on each end of the tracks can be independently operated for forward and reverse travel, pivot steering and counter-rotation. The hydraulically driven system offers better gradeability in adverse ground conditions.

The SCC8500 has 10 available configurations for main boom, fixed jib and luffing jib. Maximum main boom length is 354.3 feet (108 m) on the basic machine and 393.7 feet (121.1 m) with the UltraLift configuration. The fixed jib has a maximum length of 137.8 feet (42 m) in both basic machine and UltraLift. The maximum luffing jib length is 236.2 feet (72 m) for the basic machine and 275.6 feet (84 m) in the UltraLift configuration.

The crane is powered by a 600-horsepower (447.4 kW) Cummins diesel engine with 1,845 foot pounds of torque. Hydraulically driven planetary gears raise and lower the load. Maximum line speed is 568 feet (173 m) per minute. The swing system uses dual drives and planetary gear reduction to automatically center the load and precisely regulate swing speed up to 1.8 rpm. The track roller system is maintenance free. A centralized system automatically lubricates the slewing bearing and other grease points on the crane.
