The finalists for the ESTA Awards 2020 have been announced by the jury of experts.
A record number of entries were received for this year’s European Association of Abnormal Road Transport and Mobile Cranes (ESTA) Awards of Excellence. These are presented during the annual ESTA Users’ Night and Awards gala dinner and presentation event.
A maximum of four finalists are shortlisted in each of the ten categories. The 38 selected this year come from 24 companies and 13 countries. They were chosen from a larger group of entries than in any previous year. The 2020 list once again shows how the awards have become a major pan-European event.
Please note that the awards will now take place on a new date, 24 September. The date has been changed again because of the impact of the coronavirus Covid-19 and the awards will now be an online virtual event.

FINALISTS BY CATEGORY
Cranes: telescopic, lifting capacity more than 120 tonnes
Lifting large steel girders weighing 75 tonnes in difficult conditions near an airport runway meant height restrictions and placing the crane on 6 metre high supports surrounded by a 20 me concrete wall.
A way had to be found at short notice to replace a 12.6 metre diameter storage tank between five pipe racks in a no-lift zone at a chemical plant which was still running and the tank had turned out to be much heavier than projected.
Schot Verticaal Transport
To replace a large yard crane’s slewing ring the entire 80 metre boom weighing 150 tonnes had to be removed from the mast in one lift, using a trio of mobile cranes working together in one triple crane lift.
Lifting and placing six girders, each weighing up to 85 tonnes, in a small and restricted site was achieved in daylight and without additional traffic holdups using 700, 500 and 400 tonne wheeled mobile cranes.
Cranes: lattice boom
A pair of large wheeled mobile cranes supported by a pair of smaller telescopics was used to lift multiple components of a steel bridge weighing a total of 390 tonnes linking the tops of two tower buildings at a height of 82.5 metres.
A sequence of lifts completed using a pair of 1,1350 tonne lattice boom crawler cranes culminated in a spectacular 753 tonne tandem lift of a 12 MW wind turbine nacelle installed with a hook height of 166 metres for a hub height of 135 metres.
Installing a 48.6 metre diameter tank roof weighing a total of 124 tonnes was achieved using one 750 tonne crane lifting the delicate steel structure via 14 attachment points at 35 metres radius to a height of 12 metres above the ground.
Exchanging a pair of 350 tonne legs on a jack up barge meant a 1,250 tonne capacity crawler crane with a capacity-enhancing boom system lifting at a radius of 37 metres with the boom tip at a height of 132 metres – and all that after the crane had been assembled 16 metres below street level at the bottom of a dry dock.
