New Demag TCC 160 telescopic crawler crane
With the Demag® TCC 160, Terex Cranes is re-entering the telescopic crawler crane range. The crane closes the gap between the capacity class of 130 to 220 tonnes. The TCC 160 is also a real all-rounder with its actual lifting capacity of over 150 tonnes and a maximum load moment of 590 mt.
The Demag TCC 160 telescopic crawler crane is a thoroughly versatile machine: It has a track width that can be adjusted as necessary in both symmetrical and asymmetrical configurations so that it can be used for applications in which space is at a premium, such as bridge construction projects. It is also perfect for doing construction work, where it is not only able to move and telescope components, but also luff down and retract the boom and then travel underneath roof structures to get to where it needs to be. In addition, the crane is also able to bring its strengths to bear as an assist crane, as well as when carrying out wind turbine pre-assembly work. And since the load charts for its 60-meter-long main boom are excellent even when lifting on an uneven grade, for angles up to 4°, its use requires less topographical ground preparation onsite than a lattice boom crawler crane. For example, it can lift a full 36.4 tonnes at a radius of twelve meters when working on an inclination of 4° with the main boom at a length of 34 meters.
Four main boom extensions
With a main boom length of 60 meters, the TCC 160 already features the longest reach in its class, and yet it can be increased further if necessary. Main boom extensions with lengths of 5, 11, 17, and 23 meters that can be mechanically and hydraulically offset are available, meaning that a maximum system length of up to 83 meters is possible. The five-meter extension can be folded onto the side of the main boom for transport to save space.
Maneuverable and powerful chassis
In addition to a large lifting capacity, the TCC 160 provides nearly the same maneuverability and ease of operation as an excavator with its travel pedals. Moreover, the fact that the joysticks can be used to control the tracks complements the machine’s convenient controls. Part of this is feasible thanks to the unit’s outstanding traction power and durable B9HD track components with bolt-on double grouser shoes or flat shoes. This robust design, which features a powerful travel drive, provides the crane with a traction force of 1,450 kN – the highest of its class. In fact, it is significantly higher than even that of competitor models in the higher 220-tonne class, and in addition makes it possible for the TCC 160 crane to turn under load on the spot even with its narrowest track width. The crane’s gradeability goes up to 50 percent, while its maximum travel speed is 2.4 km/h and its ground clearance is 420 millimeters.
Another aspect worth highlighting is the various track widths with three pinned positions of 3.5, 4.75 and 6 meters, as well as the continuously variable unpinned track widths, which can additionally be used in an asymmetrical configuration. The tracks can be adjusted both when stopped and when traveling while the control system monitors to ensure the crane remains within an allowable configuration. The crane is designed with an intelligent control system, based on the tried-and-true IC-1 Plus, that determines automatically the permissible lifting capacity under consideration of a number of factors, including ground incline, slewing position, and track adjustment.
A design optimized for transport
The base crane has a transport width of three meters and a transport height of three meters, meaning that the TCC 160 is extraordinarily compact for its class. The heaviest transport unit weighs 46 tonnes. However, if necessary, this weight can be reduced to 41 tonnes by simply removing the sliding beams used to adjust the track width. The two crawlers have a gross weight of approximately 18.5 tonnes each when equipped with one-meter track shoes; the two central ballast units weigh 7.5 tonnes each; and the counterweights, including the base plate, weigh 45 tonnes. The maximum operating weight of the crane is just under 150 tonnes.
The engineers at Demag have attached enormous importance to ergonomics when it comes to the crane’s setup. All setup steps are automated and controlled by remote control. In addition, hydraulic quick-connect couplings are the type of coupling that is predominantly used, which makes fast and efficient work possible. Accordingly, the TCC 160 crane features permanently installed hydraulic outriggers with outrigger pads to make it possible to easily unload the base crane from a lowbed trailer.
In addition, the TCC 160’s self-assembly operation also includes the installation of two 7.5-tonne central counterweights that mount on the car body, the 45 tonnes upper counterweight stack on the superstructure and the second hoist.
Ergonomics at every turn
The TCC 160 crane’s accessibility is designed to ensure that work on the crane can be performed comfortably and safely. This is the case during transport, setup, and operation – even when the tracks are being adjusted as the placement of the permanently installed grating platforms adjust automatically. The crane can even be fueled while on a lowbed trailer, and the cab can be easily accessed during setup in order to start the machine for self-assembly. Permanent ladders and ladder attachment points for the included loose ladder are located strategically around the crane for access to key components during all stages. The crane also features anchors for personal fall arrest system at the intended ladder support points.
Powerful and environmentally friendly engine
The TCC 160 crane is driven by a six-cylinder MTU engine with an output of 230 kW and a torque of 1,300 Nm. This engine complies with Euromot 5 specifications, as well as with Tier 4 Final specifications for the US market. There are two operating modes that should be highlighted in particular: At a speed of 1,500 rpm, the diesel engine will run in an ECO mode that optimizes fuel consumption, while at a speed of 1,800 rpm, it will have a Power Boost function available. This function provides a noticeable output increase and makes it possible to carry out simultaneous movements at high output / speed while traveling or rotating.
The two hoists on the TCC 160 also make a compelling case. The primary and auxiliary hoists are technically identical, with both featuring a 245-meter-long, 26-millimeter-thick, grade 1960 steel wire rope with a high line pull of 13.7 tonnes. The wire rope’s high line pull makes it possible to lift heavy loads with low reeving, saving time during setup and re-reeving.
