About this product
The longest-reach model in the crawler range: 22 m horizontal reach, 24.5 m vertical reach. It moves around the site on its own tracks, with no crane needed.
A mobile solution combining all the features of the spider boom with a crawler undercarriage. It moves around the site without a crane and stays stable on uneven ground. Its low unfolding height lets it work in low-ceiling areas such as tunnels, metro stations, car parks and basements; combined with a trailer pump it forms an economical pump-and-placing system for long linear work such as diaphragm walls and tunnels. It can also be detached from the crawler and used as a free-standing, crane-placed distributor.
