Raimondi Cranes has unveiled its most powerful luffing crane to date, the LR372.

Equipped with Raimondi’s next-generation high performance winches, the LR372 is a 370tm class crane with a maximum jib length of 60m and a maximum capacity of 20t in two falls configuration. At the maximum radius, the LR372 can lift 3,795kg using Ultralift mode. The crane’s main design engineering aspects are based on the luffing LR330 that was launched last year.

Domenico Ciano, chief executive officer at Raimondi Cranes, said: “One very important feature of the LR372 is that it may be installed on two different types of towers: for an internal climbing system, the new GR5H tower at a width of 2m, or the 2.3m width GR6 tower series (GR6B, GR6 and GR6L inclusive), for standard, external, and internal climbing configurations.”

Ciano added that Raimondi worked closely with its supplier to develop a new motor that would optimise winch performance while reducing energy consumption, now implemented in both the LR372 and the LR330.

“Raimondi’s engineering team completed the design of our new LR372 in six months, including the new winches installed on the LR372. We have invested more than 2,000 hours between the mechanical and control system designs with a major focus on ease of use, maintenance accessibility, and structural strength.”

The LR372’s luffing movement, using the new 75kW winch, is equipped with a standard emergency brake. The raise of the jib from 14.5° to 85° takes approximately two minutes with full load.

“In terms of the hoisting movement, the LR372 is powered by the 110 kW winch with 880m rope capacity, and is equipped with the hydraulic emergency brake as a standard feature. Thanks to its outstanding drum capacity, the LR372 can work up to 380m with two falls and 820m with one fall. The LR372 can reach a maximum lifting speed of approximately 256m per minute,” said Ciano. He pointed out that the new slewing movement on this crane is driven by the two 15kW motors fully controlled by inverters, allowing it to reach a slewing speed of 0.8rpm.

The first two LR372s will be delivered to Raimondi’s official South Korean agent, Hansung Prime for a large-scale development in Busan. The new cranes will be installed to reach heights of 222m and 228m respectively, with Raimondi’s innovative EC6L external climbing system.
