About this product
18 m reach, 4-section Z-folding boom; low unfolding height of 4.2 m. For metro, tunnel and indoor pours.
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.
