Link-Belt debuts Pulse system and TCC-1100 at ICUEE

Link-Belt is demostrating its new Pulse crane operating system at the ICUEE exhibition October 4-6 in Louisville, Kentucky, USA. The company is also showing off its new 110-ton (100 metric ton) TCC-1100 telescopic crawler crane.
Introduced earlier this year at ConExpo, the TCC-1100 is the third model of telescopic crawlers from Link-Belt. The company says the crane's design focuses on robustness, simplicity and reliability for the general contractor or bare rental fleet owner.
The TCC-1100 offers a full power boom fabricated from ultra-high-strength steel. The main boom is 150 feet (45.7 meters) long and incorporates Teflon wear pucks to eliminate boom greasing. Fly jib options include a 31 to 55-foot (9.4 to 16.7 m), three-piece bi-fold lattice fly and a 10-foot (3 m) heavy-lift fly. The heavy-lift fly swings and pins into place and is integral to one of the on-board fly options. It has more than 20 tons (18.1 metric tons) of capacity and lift procedures for two-load-line picks. All flies offset to 2, 15, 30, and 45 degrees.
The TCC-1100 can be moved in four truckloads. The main load weighs under 90,000 pounds (41 metric tons) and, on the trailer, is 12 feet eight inches (3.86 m) tall and 10 feet, six inches (3.2 m) wide. All overflow loads weigh less than 44,500 pounds (20 metric tons). On site the crane can be started and the carbody outrigger jacks deployed via remote control.
On its outriggers, the crane sits wide to give a stable self-assembly platform. Tapered axles allow the side frames to install easily and the 50,000 pounds (22,680 kg) of counterweight mount to the upper using Link-Belt's patented HSL lattice crane counterweight removal system.
Link-Belt says the TCC-1100 can work at three track gauges: 19 feet (5.8 m) fully extended, 14.4 feet (4.4 m) intermediate, and 12 feet (3.7 m) retracted. It has two travel speeds and can travel up to 1.7 miles per hour (2.7 km/h) to spend less time traveling and more time lifting.
Powering the TCC-1100 is a Tier IV Cummins QSL diesel engine producing 320 horsepower (239 kW) and driving a variable displacement piston pump package. Simple pilot operated control valves distribute flow to all functions. Taking the flow are Link-Belt hoist packages using piston motors and 7/8 inch (22 mm) rope. The winches have 21,022 pounds (9.5 metric tons) of line pull and a maximum line speed of 431 feet (131 m) a minute.
The Link-Belt Pulse operating system includes a boom extend mode controller (EMC), self-diagnostic capabilities and continuous monitoring of multiple crane functions and conditions. As a rated capacity limiter, it shows maximum allowable load, load on hook, and crane geometry. It warns of an approaching overload or two-block condition and shuts down relevant operations when necessary. It also monitors wind speed and warns the operator with a visual alarm.
Pre-settable alarms can also assist in avoiding obstructions on the job site. For boom operation, Link-Belt Pulse animates the boom's mode of extension. All information for the telescoping operation can be accessed and viewed in real time.
