HEK mast climbing platforms

Contractors building a new head office for the ING Group in Amsterdam are using eight HEK mastclimbing platforms in twin-mast configuration. Maximum height is 50m and deck lengths vary from 14m to 22m.

HEK says that its MSHF model was chosen becuase it requires anchor positions at 15m intervals instead of the much shorter intervals of lighter machines and scaffolding. The building is the largest steel structure in the Netherlands, and holes had to be cut in the steel frame to fix the masts, so minimising anchor points was important.
