Weightlifter on wheels

The LTM 1750 from the German manufacturer Liebherr: It's the giant of construction sites, a telescopic mobile crane of superlatives. With a driving weight of 108 tons distributed across nine axles, it is the largest mobile crane permitted to travel on public roads with its telescopic boom attached. With its 52-meter-long metal arm, it can lift up to 800 tons – roughly equivalent to the weight of 400 mid-size sedans.
