Crawler crane manufacturers are expanding their product range and introducing advanced features to improve lifting capacity and safety to meet the needs of infrastructure development projects from various industries.
After a period of interruption, the demand for crawler cranes once again gained traction and prompted manufacturers to expand their product range to include lighter, medium and higher capacity cranes. Demand comes from windmill projects, urban infrastructure such as roads and bridges, subway projects, continuous expansion of airports and ports, maintenance of crude oil refineries and petrochemical units, and pipeline network expansion is the new demand driver. The delivery of the new LR 1700-1.0 700-ton crawler truss boom crane began in June 2020, and since October 2020, the response from rental companies such as ALE, Buckner and Biggie in the United States has been encouraging. In fact, 700 tons and 1,000 tons of demand come from Europe, South Korea, Japan and the United States, and 800 tons are also purchased. The company’s existing fleet in India includes 600-750 ton crawler cranes. Subhajit Chandra, head of Liebherr India, said: “LR1700-1.0 is equipped with a newly designed superstructure that can be transported more easily with flatbed trailers. A key design intervention (also seen in our 800 tons) is the boom Flexibility. With the powerful H-Boom design, the crane can work efficiently in windmills and industrial construction projects, such as setting up distillation towers and their maintenance in oil refineries, and working in cement plants.”
He added: “As the hub height of Indian windmills is getting higher and higher (more than 130-140 meters), the weight of the nacelle of 3.5 MW wind turbines is also getting heavier (such as Suzlon, Vestas, Gamesa and General Motors). As Electric does), cranes will be increasingly used in India.”
The new LR 1700-1.0 crane is manufactured in accordance with the EN13000 standard and is equipped with a variable counterweight. Its radius can be automatically adjusted by the control device according to the load that the crane will lift in a given radius. Equipped with a standard safe load indicator system, the crane can automatically calculate its inclination when working on the windmill site in hilly areas.
