Shaft Underpinning Capabilities

These robust frames enable segments to be safely secured, slung, and precisely located while positioned on the frame itself - improving efficiency and safety during installation. Designed and tested in-house, the Segment Underpinning Frame accommodates a wide range of segment sizes using a single universal frame. Segment restraint hooks and a segment bolt ensure the unit is held tightly in place, while an offset lifting point prevents damage from chains or crane blocks—particularly beneficial when working in deep shafts.

Key specifications:

Suitable for shafts with diameters ranging from 5m to 25m
Safe Working Load (SWL): 4000kg
Compatible with most standard shaft segments

These frames are a reliable, engineered solution to streamline the underpinning process while reducing risk to personnel and materials.
