Our H series tank-brace manhole frame system is designed for large excavations up to 15 meters square. It allows large tanks to be installed into clear unobstructed excavations.

Adjustment is achieved by a 1mtr mechanical adjustment, and then a 1mtr stroke double acting hydraulic cylinder which also gives hydraulic retraction of the manhole frame to facilitate ease of removal.

We offer a full Design and Quotation Service for your excavation, big or small.
