US construction company Willbros has hired Sany crawler and rough terrain cranes from local dealer Four Seasons Equipment to help construct a gas pipeline in Texas, USA.
Working at two locations, one near Hallettsville and another near Cotulla, are three 110 US ton (100 tonne) capacity SCC8100s and one 65 US ton (59 tonne) extra-long-boomed SRC865XL.
Wilbros' engineers are building fingers for slug catchers along the pipeline, a job that requires assembling a 42-inch (1 m) schedule 888 pipe to capture condensed gas as it moves down the pipeline.
The cranes have been brought in to do tandem lifts working with tubing that weighs 400 pounds per foot (580 kg per metre) and comes in 40 foot (12 m) sections. Once six or more sections are joined together, the weight totals 100,000 to 120,000 pounds (45-55 tonnes), while the completed slug catcher holds roughly 500,000 gallons (1.9 million litres) of fuel.
