We’ve enjoyed documenting the recent decommission of the temporary mast at Bilsdale on the North Yorkshire Moors.
The particular crane used was Commhoist’s LTM1130-5.1 to reach the top of the 80m tall tower. For successful completion, this project required 60m of main boom, a 7m fly-jib insert, as well as a 19m fly-jib totalling 86m. This was working at a 22m radius with 22.6m of ballast.
The only issue with the aforementioned equipment was the crane couldn’t weigh more than 48 tonnes due to the weight limit of a bridge on the project’s access route. To combat this, we worked collaboratively with the manufacturer to strip the crane down in our yard, before all the pieces were transported to site and re-built in-situ.
The fly-jib had to be removed, three outriggers, all 22 tonnes of ballast, the hydraulic hose reels, the toolbox, steel outrigger plates and the hook blocks. As you might be able to imagine, this needed 3 rigid vehicles to transport to site, in addition to our LTM1040-2.1 to assist in dismantling and rebuilding the crane on site.
Commhoist built this Bilsdale mast over a year ago, to 50m high with our 60 tonne crane. However, it was thought that any larger crane wouldn’t get up onto the moor for a few reasons including, the difficulty in access, the weight limit on the bridge and the 1200-foot climb onto the moor. The top three sections were installed using a helicopter – at great expense!
Our client Evolution contacted Commhoist to find a solution to remove the mast and the 178 concrete blocks each weighing 750g of which the mast was guyed too.
We’re glad to say the mast has been successfully removed and work has started on stripping our crane down again to remove it from site.
