Why the FOCUS30


Small footprint, big lifts - Large industrial facilities become more complex and crowded. Cities expand and become congested. At the same time, development work must continue.

So, Mammoet created the FOCUS30.

Back to

The Mammoet FOCUS30 is the ideal lifting machine for use in areas with complex infrastructure and space limitations, such as plants and inner cities.

It has the capacity, versatility, and reach to work in and around different layouts and requires a minimum amount of space for assembly and operation. Its small footprint helps optimize the plant layout of brownfield projects.

We understand when it comes to cranes, added value is not limited to capacity. Therefore, we designed the FOCUS30 to be erected vertically and maneuvered with flexibility, making it ideal for efficient and safe project execution in limited and congested spaces.

What’s more, its design includes a variable superlift system, which increases the crane’s flexibility and delivers a larger operational window - particularly in congested areas.

Technical details

No other crane can be assembled in a small area like the FOCUS30.

A small assembly area

This contributes significantly to safety and efficiency during its assembly phase. Among other advantages, it is no longer necessary to lift crane elements over live infrastructures, such as pipe racks, nearby buildings, and of course, people. Multiple innovations and improvements have made this possible:

  • Main boom mast sections are provided in sections and are erected using a guidance system that allows vertical mast build-up
  • A specific masthead enables hoisting or lowering of the back mast during crane erection or disassembly
  • A feed system on the crane’s upper structure allows safe and convenient insertion of mast sections
  • The erection frame allows stable vertical mast erection, based on a proven methodology for tower cranes. Boom stop cylinders, integrated in the support brace of the erection frame, keep the main boom mast sections vertical and stable.

A small footprint

The FOCUS30 is a vertically self-erecting crane. It can be built vertically up to a height of 150m on an extremely small surface of 30x30m, without compromising stability and strength. This is approximately the space occupied by two tennis courts.

The result is a high capacity crane that can be assembled on the smallest area possible, making it ideal for use in confined spaces. The only auxiliary lifting capacity needed is any locally available 400t hydraulic crane to lift its mast sections into place.

A high lifting capacity

The FOCUS30 is a 2,500t class crane with a 30,000t/m load moment, giving it impressive lifting capability.

A large and variable operational window

The crane has a variable and splittable superlift, which can be relocated swiftly. All of this increases its flexibility on-site - particularly in congested environments – allowing more lifts to be made using the same crane. The FOCUS30 can be at work within 10-14 days and can be assembled using a locally available 400t hydraulic crane. This makes it well-suited for projects with a strict time window for execution.

A low ground bearing pressure

The FOCUS30’s pedestal design creates stability and helps to realize low ground bearing pressure of as little as 6t/m2 – allowing it to be used on sites with softer ground, or where infrastructure below ground level must be protected. Where the surface allows, the FOCUS30 can also be skidded to additional lifting positions.


  • Load moment 30,000 t/m
  • Class of crane 2,500t
  • Outrigger setup 14x14m
  • Footprint 30x30m
  • Minimum GBP 6t/m2

Making sure you stay on schedule

Upgrade, maintenance, and turnaround projects at existing petrochemical sites often require crawler cranes to provide the necessary lifting capacity. However, crawler crane booms require a large laydown area; stopping adjacent tasks.

Crawler cranes often need to be erected above live areas of the plant, putting workers and key infrastructure at additional risk. As it can take up to four weeks for these cranes to become operational, scheduling can be severely affected.

The FOCUS30 helps plant owners in three ways:

  • First, it improves productivity by freeing up space on site. Its boom mast is assembled vertically in sections, allowing the assembly to take place from just a 30x30m footprint.
  • Second, it allows projects to start and finish sooner. The FOCUS30 can be assembled within 10-14 days and can be transported to the lift position in smaller, more maneuverable pieces.
  • Third, it reduces project risk. Boom erection does not overhang adjacent areas of the plant, so plant workers, pipe racks and other key infrastructure can operate more safely. The FOCUS30 is a 2,500t class crane, and so is ideal for a wide range of lifts, while its minimum 6t/m2 ground bearing pressure means it can operate at a wider range of sites.

 “The world’s population is predicted to rise to 10bn by 2050. As populations grow, this will trigger increased demand for consumer goods, and with this a demand for plastics.

Refineries across Europe and the US are reaching the end of their design lives; between 50 and 60 years of age. This presents owners with a choice: to shut down existing facilities and rebuild, or to expand and revitalize them? Until recently, both of these options would result in a significant downtime – and therefore costs.

The FOCUS30 can help, as it is maneuvered around key site infrastructure, meaning there is no loss of production while upgrades are made. In this fashion, it is bringing down the total cost of refurbishment.
