From the 31st of May until the 4th of June there is the CTT 2011 in Moscow. On this 12th International Show of Construction Equipment and Technologies, all major suppliers of construction equipment are present. As one of the leading companies in Russia, LIEBHERR has a prominent place on this show, presenting machines from all different factories. With a distinctive presence in the pipeline construction industry in Russia, there are also a LIEBHERR pipelayer and a LIEBHERR welding tractor on display. The machines, both suitable for working in ambient temperatures as low as -/- 40°C, were sold by Maats and are part of an ever growing LIEBHERR pipeline equipment fleet in Russia. The 90-tons pipe layer, a LIEBHERR RL64 is the bigger "brother" of the LIEBHERR RL44 with a lifting capacity of 45,9 tons. The welding tractor, the LIEBHERR SR714 LGP (Low ground pressure) is a so-called "tack rig", complete with a HIAB-crane, a 125kVA generator, 4 welding machines and a compressor.
