Link-Belt introduces TCC-800 telescopic crawler crane

The latest telescopic crawler crane from Link-Belt, the 75-t TCC-800, comes with a new four-section 11.8 – 36.5 m full-power boom that reaches a maximum tip height of 56.2 m with full boom and Link-Belt’s SmartFly pinning system.

The SmartFly system helps to ensure proper fly erection and stowage sequence while minimising work at height. The TCC-800 offers optional one or two-piece 10.6 – 17.6 m fly.

According to Link-Belt, the TCC-800 will begin field-testing soon and its first shipments is scheduled to take place in the fourth quarter of 2020. The company said the crane’s predecessor, the top-selling TCC-750, has been a cornerstone of the telecrawler market since its initial debut in 2008.

New to Link-Belt’s telecrawler lineup is variable side frame track positions (V-CALC) on the TCC-800. “VCALC, in the case of the new TCC-800, offers the added flexibility to operate the crane with side frames in asymmetric configurations. Pulse 2.0 monitors actual side frame position, auto-selecting the correct chart,” explained Scott Knight, Link-Belt’s product manager for lattice and telescopic crawler cranes.

The TCC-800’s variable side frame combinations, new cab with 20 degrees of tilt and Pulse 2.0 offer an operator a multitude of options for any jobsite - everything from pile driving, bridgework to plant work, and general construction. The crane also has an optional wireless remote control system, which allows the operator to be out of the cab and still have control of the machine.

The TCC-800 will utilise a Stage 5 dual-compliant Cummins QSB 6.7 engine with 232 hp at 2,000 rpm for greater fuel economy, improved quiet operation and cold-start capability. Other advancements include pressure read-out on all hydraulic circuits, viewable on Pulse 2.0 display.

Total vision package with right-side swing camera, winch-view camera, and rear-view camera give the operator great jobsite visibility during setup and lifting. Single axis or joystick controls are also available both offering operator selectable foot or hand controls for travel operation. Textured paint on all vertical surfaces and slip resistant paint on all horizontal surfaces improves durability and footing.

In addition, new high-performance variable displacement pumps provide power control and load sensing on the TCC-800 for smooth functioning of all operating processes. Matching 19 mm grooved drums have 254.2 m of rope capacity with 7,656.6 kg maximum line pull and 147 mpm maximum line speed. The list chart on the TCC-800 also includes a maximum four-degree list chart for increased performance in varying jobsite conditions.

The TCC-800 self-assembles with 17,463 kg of upper counterweight and two 1,360-kg sections of carbody counterweight. For transport, the crane moves in two loads: main unit transports under 45,359 kg with fly, side frames attached, hook block and ball, lifting sheave and full tank of fuel; overflow includes counterweight sections and stays below 20,184 kg. Clearance height on a lowboy transport trailer stays below 3.9 m.
