Link-Belt TCC-2500 is highest-capacity telecrawler available

For customers across the globe, Link-Belt is announcing a solution for expanding the top end of telecrawler fleets with the highest capacity telecrawler currently available in the market. Link-Belt is unveiling the all-new TCC-2500, a 250-ton (227-mt) telescopic crawler crane to its lineup. The TCC-2500 will make an ideal addition to any general construction, power transmission, wind farm, power industrial or large crane rental fleet.

“The long-term plan for our telecrawler lineup brought us to this point in time, and the TCC-2500 is well positioned to lead the telecrawlers into a whole new arena of jobsite opportunities. We identified early on that our customers needed a telecrawler with higher capacities and greater reach,” says Link-Belt Product Manager, Lattice and Telescopic Crawler Cranes, Scott Knight. The TCC-2500’s jobsite flexibility is a huge benefit. The TCC-2500 can lift, reach and travel like a large fixed boom lattice crawler, while also having the ability to retract the boom and reduce its overall profile as jobsite conditions and environment require.

The TCC-2500, with its Tier 4 Final Cummins QSL 9 diesel engine and seven-section formed boom, will make a public debut in Las Vegas, NV at ConExpo 2017 March 7-11. Production units of the TCC-2500 will be ready for shipment in March.

Overall, the TCC-2500 establishes a new definition for robust performance for large telescopic crawler cranes. The seven-section 43.7- to 223-foot (13.8- to 67.9-m) pin and latch boom is the longest in class and offers eight simple boom extend modes. The attachments will also be sure to impress with a three-piece offsettable fly that measures 12, 40 and 67 feet (3.6, 12.1 and 20.4 m) and can also be equipped with two 25-foot (7.62-m) boom extensions for an overall tip height of 346 feet (105.46 m). These attachments with optional hydraulic luffing allow for “up-and-over” capacity like luffing lattice crawlers. “Our goal from the beginning was to supply a simplified design, quick and easy to assemble that is operator friendly,” says Knight.

Another key feature for this 250-ton unit is an extra-wide winch design that can handle its maximum permissible line pull through the fourth layer – front and rear winches are matching. The rear auxiliary winch can be removed for transport weight reduction and a power pinning system mitigates work at height exposure. The TCC-2500 is a purpose-built design like the rest of Link-Belt’s TCC line, not an all-terrain upper conversion.

Operator’s cab and interface

Operators will appreciate the new 10-inch (25.4-cm) full-colour display that incorporates both RCL and engine data. The display has been carefully selected to have a resistive touchscreen that can be used with gloves and be seen in direct sunlight with larger, clearer images on display. Electric cab controls come with unparalleled functionality and increased customization and ergonomics. Operator jobsite view is enhanced with four cameras: rear-view, blind-side swing-view, and two individual winch-view cameras that provide increased jobsite awareness and control of the jobsite from inside the cab.

Lower carbody

Track gauge for the TCC-2500 is rock solid at 20 feet 4 inches (6,210 mm). The lower carbody is a hook and pin system which will make assembly quick and easy. The TCC-2500 can self-assemble side frames with standard equipped carbody jacks and wireless remote control for hydraulic pinning and jack operation. Customers will utilize new two-bar grouser track shoes that provide excellent traction with standard nylatron pad inserts to protect sensitive ground surfaces when needed.

Transportation

One of the most important things about the TCC-2500 is its ability to move quickly and easily on or off the jobsite. The main transport load weighs under 106,000 pounds (48,000 kg). The TCC-2500 can be assembled with far fewer and less complicated steps than the competition. Once off a trailer, carbody jacks can be deployed via remote control. On jacks, the crane sits wider than the competition for a solid self-assembly platform with hook and pin side frames that hydraulically pin. Link-Belt’s proven TCC counterweight system attaches 154,000 pounds (69,853 kg) of upper counterweight and is a 9-piece modular design (allowing for partial counterweight capacity charts) and transports on seven overflow loads, all 44,000 pounds (19,958 kg) or less.

Standout features of the TCC-2500:

• Longest main boom in class at 223 feet (68 m)
• 346 feet (105.4 m) maximum combination tip height
• 20-degree tilting cab
• 28,566 pounds (12,957 kg) maximum line pull
• 405 feet/min (123.4 m/min) maximum line speed
• Standard, watertight tool box mounted to front carbody counterweight
• Telematics in place to give real time data to better forecast maintenance and service needs of the crane.
• In-cab ground bearing calculation
• Selectable joystick travel mode
• Optional boom launching system with hydraulic pin pulling
• Optional hydraulic off-settable fly (2 – 45 degrees)
