Netherlands-based tower crane manufacturer Montarent has launched a new mobile self erecting tower crane, the Montalift M21 4-WDS. The 21 tonne-metre crane can lift 1.8 tonnes and can be fully erected within 10 minutes via radio control and display.

Special features, the company said, include a Potain superstructure with a galvinised tower and compact galvanised lattice jib, a jib length of 85 feet and a lifting height of 18.6 metre or 26.5 m with raised jib. The crane can also travel fully erected on site if on a flat surface and has double wheels so punctures are not a problem, the company said.

The M21 4-WDS comes with two-speed electro-mechanical four wheel drive and four wheel steering. It has four extendable hydraulic outriggers giving a square base of 4 x 4 m.

A primary advantage of this crane is its high mobility on site, the company said.
