Bernadette Ballantyne talks to Liebherr’s Christoph Eiwan about some of the challenges posed to tower crane standards bodies and manufacturers by a move to cycle-based classification.
Closing the loop
Harmonization of design standards is not an easy task but it is an important one. A huge number of committees consisting of the world’s leading crane and machinery experts are currently working on updating standards to ensure that cranes are operating as effectively and safely as possible.
As time goes by
As design standards increasingly adopt cycle-based classification, Bernadette Ballantyne talks to Professor Markus Golder who explains how to move between this and the previous time-based approach. Over the following pages, Eberhard Becker of Terex traces the adoption of cycle-based classification across the lifting industry, and Liebherr’s Christoph Eiwan talks about some of the challenges posed to tower crane standards bodies and manufacturers by a move to cycle-based classification.
Paola De Pascali attended the M. Verschoor 50th anniversary event and spoke with the founder Marteen Verschoor about the crane hire company’s history and growth.
Western Europe projects round up
This month we review projects from Germany, Austria, France and Spain.
A market in stand-by
Paola De Pascali visited Vertikal Days, shortly before the Brexit vote, and found many crane manufacturers and dealers expressing their concerns over the uncertainty the referendum had caused. Even after the vote, many investors are taking a “wait-and-see approach” and putting big projects on hold.
Cranes on the beach
This year’s CICA conference takes place in Cairns on 15-17 September
Raising the mast
Over the past year, Rapid Response Solutions (RRS) oversaw the lifting and rigging of Magma Structures composite masts for a yacht in Portsmouth, UK.
Lighter than air
Airships are set to return to our skies with projects planned across the world. Rhian Owen investigates why there is a new-found attraction of airships such as the Airlander in the UK, and how remote construction projects could benefit.
Low oil pressure
Persisting low oil prices have kept the rough terrain crane market soft in 2015 but competition in the larger machine space is rising with demand for these machines remaining strongest, Bernadette Ballantyne reports
Enercon uses Liebherr tower crane for 149m wind turbine
Enercon used a Liebherr 1000 EC-B 125 Litronic tower crane to erect a 149m wind turbine at an altitude of around 800m in the Prechtaler Schanze wind farm in the Black Forest.
Mammoet erects tallest gantry ever in Europe
One of the world’s largest gantry cranes has been erected at a port in Poland. The new 120m crane will be used for moving steel fabrications. Raising the crane was itself a major lifting challenge for contractor Mammoet.
New jib for Chernobyl crawler
A Manitowoc 2250 crane has been fitted with a new luffing jib to complete containment shelter work at the disused Chernobyl nuclear power plant in Ukraine.
Planning really matters
The Mecca crane accident in 2015 killed over 110 people, making it one of the worst such accidents in modern history. This February, an accident in New York killed one person and injured 15. These accidents, Paola De Pascali reports, highlight the importance of careful preparation for high winds when using crawlers.
Watching the weather
Crawler manufacturers and best practice guides recommend the use of well-placed anemometers as one element in keeping crawlers safe from high winds. Here, we round up some of the equipment on offer.
Réunion road rolls ahead
A €1.7bn project to link St Denis, the capital of the French Indian Ocean department of Réunion, with the island’s port near La Possession, is getting well underway.
Western Europe projects round up
This month we review projects from Manchester, Netherlands, Poland, Italy.
Getting it right
A recent job by ALE, using an LR 11350 working at height in an area where high winds are a risk, demonstrates the sort of planning needed for safe working in these conditions.

Richard Marcotte, an instructor at ITI, argues that rigging skills are too often taught with specific trades in mind, rather than in their own right.
Jack up systems and strand jacks offer a powerful way to lift huge loads, yet are often easier to deploy than large cranes. Rhian Owen looks at recent projects that demonstrate the flexibility of these systems, and considers their limits and potential.
