The mast climbing work-platform is a combination of scaffold, material hoist and building cradle, providing safe and efficient access to the building surface. It transports workers and materials to precisely the height required; loads of up to 3.5 tonnes can be carried up to a height of 200 meters. Height and length can be adjusted quickly and conveniently. The work-platform can be used in a single mast configuration with platform length from 2.7m to 10.1m or in a twin configuration with platform length from 8.2m to 23.2m. The masts are anchored at 6 – 8m intervals. With the MSHF unit, a freestanding height of up to 20m can be achieved when mounted on a chassis.
