Mammoet said: “The Focus30 will enhance construction projects in oil refineries and cities; where stronger regulation and a growing population means lifts are surrounded by live plant, buildings and people. Its low ground bearing pressure helps to protect underfoot infrastructure such as tunnels and cabling and reduce disturbing the land prior to lifts.”
Two phases of testing of the Focus30 took place and were observed by an independent third party surveyor from Lloyd’s Register. First, the crane was assembled in its SFSL fixed jib configuration and subjected to 125% of its maximum recommended load. Testing lasted for one week.
Second, the crane was re-assembled, this time to its SSL configuration, with 90m boom but no jib, and again loaded with 1,250t. Testing in this configuration lasted for three days. Side load, swing load and maximum radius testing was performed during both phases with repositioning of its superlift between tests taking just two hours each time.
The crane is now compliant with the EN 13000 standard for mobile cranes, and with F.E.M. 5.004, which governs the design of steel structures of general use.
