Record Raptor?

An Artic Crane Raptor articulated tower crane has been erected with a hook height of 88 metres, which is thought to be a new record.

The crane is working on the site of Amazon’s new headquarters in Worship Street in the City of London, the main contractor is Brookfield Multiplex.

The Raptor was originally erected by one of the Comedil luffers on site, and the plan was to use the same crane to raise the Raptor for the upper stories of the building. However the concrete slip form grew faster than the steelwork so it was not possible to tie the Comedil in and climb it to a suitable height in time for this operation. So the crane’s owner and operator, City Lifting had to organise a road closure and bring in its 300 tonne, long boom Grove GMK6300L to do the job. City Lifting believes that this is the highest Raptor ever assembled.

The Grove was rigged with is fully extended 80 metre main boom plus 12 metre hydraulic luffing swingaway extension. The entire Raptor jib, hoist and hook form a single unit so the assembly / reassembly involves fewer lifts. The Raptor has an out of service radius of just four metres, ideal for this type of inner city job site.
