Wilbert builds 47,000 tonne silo installation

Rental and transport company Wilbert has helped build a 47,000 tonne storage silo in Brake, Germany.

To build the silo, which is for grain and fodder, a WT 200 e.tronic tower crane and a WT 300 e.tronic tower crane were used.

Both cranes were fitted to 14 metre base frames to help save space, as the rails on the silo had to remain in operation during the installation process, a company spokesperson said. The frames were fitted on top of the silo cone. In addition, anchor rods were also mounted to the foundation.

For the task the WT 300 was assembled with a freestanding tower height of 84 m and was configured to work within a 55 m radius. The WT 200 had a tower height of 73 m and was configured with a 40 m jib. Jobs for the towers included lifting 40 tonnes of steel each day.

The silo covers an area of 22 x 61 m and measures 83 m high. It was built in two sections. The first section took 27 days to complete and the second took 21 days, a company spokesperson added.
