Mammoet FOCUS30 Successfully Completes All Testing


Dec. 16, 2020 - Mammoet’s crane for confined spaces, the 2,750-USt FOCUS30, has completed all required testing and is now being disassembled, ready for mobilization to its first project. Over the last few weeks, the crane undertook a series of controlled tests to certify its strength and safety.

The FOCUS30 will enhance construction projects in oil refineries and cities, where stronger regulation and growing populations mean lifts are surrounded by buildings, people, and live facilities.

Its low ground bearing pressure helps to protect underfoot infrastructure such as tunnels and cabling and reduce disturbing the land prior to lifts.

The crane will also help speed up project schedules, for example by allowing more cabling and pipework to be installed while lifting is completed.

FOCUS30 testing took place in two phases, both under Lloyd’s Register, an independent 3rd party surveyor who worked alongside Mammoet during design of the FOCUS30.

First, the crane was assembled in its SFSL fixed jib configuration and subjected to 125% of its maximum recommended load.

Next, the crane was re-assembled, this time to its SSL configuration, with 295’ boom but no jib, and again loaded with 1,375 USt. Testing of the SFSL configuration lasted about a week. Testing of the SSL configuration lasted three days.

Side load, swing load, and maximum radius testing was performed during both phases, while the crane’s international crew looked on. Repositioning of its superlift between tests took just two hours each time, rather than one to two days – a feature that will reduce plant downtime when the crane starts project work.

Following completion on both phases, the crane is now fully 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. The crane will now be disassembled, ready for mobilization to its first active project, taking place in the UK.

Mammoet has produced a 360-degree virtual tour of the crane. Click here to see the tour in action: https://mammoet-focus.nl.
