With the presenting of the Demag TCC 160, Terex attempts to close the gap in the market between the 130 and 220 tonne capacity classes offered by competitors. The TCC 160 has a lifting capacity of over 150 tonnes and a maximum load moment of 590 tonne-metres.
The new model’s track width can be adjusted in both symmetrical and asymmetrical configurations allowing it to be used for applications such as bridge construction. It’s design means the TCC 160 can move and telescope components, and also luff down and retract its boom. Allowing it to travel underneath roof structures when performing construction work.
Less ground preparation is needed than a lattice boom crawler crane and with a main boom length of 60 metres, the TCC 160 already has the longest reach in its class, especially as it has no coompetitors. Main boom extensions with lengths of 5, 11, 17, and 23 metres are available and can be mechanically and hydraulically offset, meaning that a maximum system length of up to 83 metres is possible. The crane’s five-metre extension can be folded onto the side of the main boom to save space during transport.
Another aspect to highlight is the various track widths with three pinned positions of 3.5, 4.75 and 6 metres, as well as the continuously variable unpinned track widths, can be used in an asymmetrical configuration. Adjustable both when stopped and when travelling, the control system monitors the tracks to ensure the crane remains within an allowable configuration.
With dimensions of just 3 metres wide and 3 metres tall, the base crane is extraordinarily compact for its class. The heaviest transport unit weighs 46 tonnes. 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 1 metre 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.
Designed with ergonomics in mind, all setup steps are both automated and controlled by remote control. In addition, hydraulic quick-connect couplings make fast and efficient work possible. Permanently installed hydraulic outriggers with outrigger pads make 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.
Designed to ensure that work on the crane can be performed comfortably and safely, the crane can even be fuelled while on a lowbed trailer, and the cab can be easily accessed during setup to start the machine for self-assembly. Permanent ladders and ladder attachment points are located strategically around the crane for access to key components during all stages. The crane also features anchors for personal fall arrest systems at the intended ladder support points.
The TCC 160 is driven by a six-cylinder MTU engine with an output of 230 kilowatts and a maximum torque of 1,300 Newton-metres. The engine complies with Euromot 5 specifications, as well as with Tier 4 Final specifications for the US market. The diesel engine has both an ECO mode and a power boost function, which according to Terex provides a noticeable output increase and makes it possible to carry out simultaneous movements at high output speed while travelling or rotating.
