The Hook system extends the possibility of Valifter lifting systems, allowing them to be mechanically anchored to manholes. Hook is available in different sizes to allow operation on manholes of different dimensions.

Hook allows breaking the encrustations, even the most consistent, on the manhole covers through the action of the tie rods. The mechanical bar can be used as a manhole cover unblocking device or as a lifting accessory, together with the manhole cover lifter trolleys.

Hook complies with the provisions of the Machinery Directive 2006/42/EC, the Atex Directive 2014/34/EU and further harmonized standards, for use in ZONE 1 and ZONE 2
