Shore 4m Trench Box

The Shore 4m trench box is our most popular shoring unit with the ability to support trenches of any depth up to the 60kPa working load limit.


The 4m trench box is a safe and versatile trench shoring solution able to be handled by mid range excavators, with heavy-duty steel construction and good clearance under the bottom strut. Internal working widths of 0.6m to 4m can be achieved with heavy-duty pipe struts, enabling this box to be used as a dig and push trench box in loose soil conditions, or as a drag box in cohesive soils.


Top extension units of 1.5m enable quick installation to full depth of shoring in all ground conditions. The panel sections are foam filled to limit water and soil infiltration, which can minimise weight gain in wet soil conditions.


Shore Hire’s trench boxes have been used in a variety of projects including Tullamarine, Padstow and Penrith
