Cranes and Lifting finds out more about Link-Belt’s recently debuted TCC-800, an all-new 72t capacity telescopic crawler crane.
The TCC-800 telescopic crawler crane debuted at ConExpo 2020 and began field-testing shortly after. First shipments are scheduled for the fourth quarter of 2020. Its predecessor, the top selling telecrawler TCC-750, has been a cornerstone of the US telecrawler market since its initial debut in 2008.
The TCC-800 comes with a new four-section 11.8m-36.5m full-power boom that reaches a maximum tip height of 56.2m with full boom and Link-Belt’s SmartFly pinning system. Link-Belt SmartFly helps ensure proper fly erection and stowage sequence while minimising work at height. This SmartFly system continues to get high marks from industry owners. The TCC-800 offers optional one or two-piece 10.6-17.6m fly.
New to Link-Belt’s telecrawler lineup will be variable side frame track positions (V-CALC) on the TCC-800.
“V-CALC, 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,” said Scott Knight, Product Manager Lattice and Telescopic Crawler Cranes.
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.

TCC-800 will utilise a stage five dual-compliant Cummins QSB 6.7 engine with 232hp at 2000 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.
New high-performance variable displacement pumps provide power control and load sensing on the TCC-800 for smooth functioning of all operating processes. Matching 19mm grooved drums have 254.2m of rope capacity with 7 656.6kg maximum line pull and 485 fpm (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 17,463kg of upper counterweight and two 3,000 1,360 kg sections of carbody counterweight. For transport, the TCC-800 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 20,184kg. Clearance height on a lowboy transport trailer stays below 3.9m.
Optional wireless remote
TCC-800 has an optional wireless remote-control system which allows the operator to be out of the cab and still have control of the crane.
