Project
Twelve 7te tanks through a tight door and into a pit
An international company setting up a new foam manufacturing facility in Swindon needed 12 tanks, each weighing 7te, offloaded, taken inside and stood up in a pit. Another firm had looked at the job before us but could not commit to it.
We offloaded the tanks with a mobile crane and used two electric pick and carry cranes to carry them in through a very tight opening. Inside, a city crane lowered each tank into the pit and then worked with one of our pick and carry cranes to top and tail it upright under the roof ridge, where headroom was tight. Each tank was then skated into its final position on a jig we made for the job, and the whole sequence was repeated for all 12. We also returned for a tandem lift to help install new overhead cranes.
The client had all 12 tanks in position without damage, on a job another firm had not been able to take on. It needed a mobile crane, pick and carry cranes, a city crane and a lift and shift crew working to one plan.

Cranes
A Liebherr LTM 1060-3.1 offloaded the tanks from transport. A Valla 120E and a Valla 75 electric pick and carry crane took them inside. A city crane lowered them into the pit, with the Valla 120E helping to stand them up. For the overhead crane installation we used a Liebherr LTM 1095-5.1 and a Liebherr LTM 1090-4.1 in tandem.
Tackle
Each tank was skated into its final position in the pit on a custom jig made for this job.
Team
Our appointed person planned each stage: offloading, shifting, ingress, lowering, top and tailing and skating. One of our directors supervised the work on site, with our operators, slingers and riggers carrying it out. Every tank was positioned without damage.
The Valla 120E is a 12 tonne electric pick and carry crane with a 7.2m boom extension, available on hire with or without an operator, or as part of a contract lift.
The Liebherr LTM 1060-3.1 is a 60 tonne, three axle all-terrain crane with a 48m main boom, supplied with an operator for crane hire or as part of a contract lift.
The Valla 75E is a 7.5 tonne electric pick and carry crane with a 5.4m boom extension, available on hire with or without an operator, or as part of a contract lift.
