High Load Manhole Frames – 400 Series

High Load Manhole Frames

This is a two component system comprising of a double acting ram with 6 extension leg sizes, allowing excavations of up to 30 metres in length to be supported with less deflection than comparable systems. The ram has 1 metre of mechanical and 1m of hydraulic adjustment.

For Large Frames over 20m please contact our design office for a design
