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.
Terex’s Demag CC 2800-2 lattice boom crawler crane is the new updated replacement for its 600 tonne capacity CC 2800-1 model.
The company’s latest addition to the Demag range was premiered at the Bauma 2019 exhibition in Germany. Terex said the underpinning idea was to further improve the performance of its proven products with technical solutions.
The CC 2800-2 has a lifting capacity of 600 tonnes and a maximum load moment of 7,700 tonne-metres. With a main boom length of 102 metres, it means that when used in the Superlift LSL configuration, its boom length extends to 138 metres. This can be further increased with a luffing jib and the Superlift SWSL to a system length of 192 metres.
In addition, the main boom combined with the lightweight rigid 12 metre LH and LF extension, allows for a length of 114 metres. The CC 2800-2 model’s basic unit was adapted to that of the CC 3800-1, to include its drivetrain.
Owners of the older CC 2800-1 model will find that several components, such as the luffing jib or the middle main boom inserts, can be used with the successor model as well. These owners would therefore only need order the new CC 2800-2 with the required components, which would therefore reduce the corresponding capital investment.
According to Terex, the CC 2800-2 was designed for simple and efficient transport. It’s A-frame and auxiliary hoist can be removed for transport and the SL mast now consists of three (previously four) separate parts. The base crane, with a height of 3.2 metres, weighs 77 tonnes. With the A-frame removed, the weight of the base crane is reduced to 62.5 tonnes.
The two frames used for the counterweight plates, instead of the conventional heavier base plates, also contribute to weight optimisation at 10 tonnes each. With the standard drive and 1.5 metre track shoes, the total transport weight is 37.8 tonnes and, with the Quadro drive it is 41.5 tonnes.
Equipped with a fall protection system, the crane’s safety features also include wide catwalks and platforms to allow for easy walking access when inspecting and maintaining the crane’s components.
The cabin from Terex’s Demag CC 3800-1 crane has been incorporated. According to Terex, the cabin’s 1.5 metre width, standard air-conditioning, CD-radio unit and ergonomic design enables continuous fatigue-free work.
The crane is also equipped with the IC-1 control system with two displays and two additional monitors that provide the operator with a continuous view of the hoists during operation.
Demag offers the CC 2800-2 with technical refinements that include the Vario SL system for continuous, flexible adjustment of the Superlift radius from 11.5 to 15.5 metres and the use of the split tray. The split tray in particular, which allows for rapidly disconnecting counterweight that is no longer required after the erection of the main boom, saves time on the construction site.
The company said the interchangeability of the counterweights among all Demag and Terex lattice boom crawler cranes in the 300 tonne class and above, also reduces costs. The CC 2800-2 accessories range is completed with the Superlift counterweight wagon, which facilitates moving the crane with the complete SL counterweight, as well as the hydraulic telescoping connector for the adjustment of the Superlift radius from 13 to 17 metres. Last but not least, the crane is also prepared for conversion to a narrower chassis with the addition of a Narrow Track Kit.
ABC Infra Equipment Purchased First New 70M Truck Mount (18-04-2019)
Mumbai-based logistics and crane rental company ABC Infra Equipment has purchased the first new 70m truck mount, from Bronto Skylift, in India.
The sale represents a general trend of higher city buildings globally and therefore equipment like the 70m working height S70XDT.
Praveen Sharma, managing director at ABC Infra Equipment, commented, “There is increasing demand for such high-reach aerial platforms and at present the population of such machines is very low. We believe there is an un-tapped market for these machines.”
Sharma added that tall buildings and factories are an increasingly common sight in India, while the S70XDT is suited to large industrial plants, refineries, shipyards and general construction work too.
“The safety awareness in India has increased by leaps and bounds in the past ten years. Also, our customers feel using such platforms will boost efficiency and productivity.”
ABC choseBronto after seeing its firefighting equipment being used successfully in Mumbai. Sharma says, “Also, they have supplied around 100 units in India. This gave us the confidence to go ahead with Bronto.” The company also bought a 62m working height S62MDT in 2016 when it moved into truck-mounted sector.
