The TuffTech Steel Heavy Duty Lower Trench Shield offers strong and reliable trench protection for contractors after longevity and practical pricing. Exclusively designed & engineered for durability and value, this trench shoring system delivers on all fronts.
The TuffTech Steel Heavy Duty Lower Trench Shield (TT-77) gives contractors a robust, flexible solution for demanding trenching work. Built from high-strength steel and available with multiple strut configurations, it can adapt to different excavation widths while delivering the durability needed for repeated use on busy civil construction sites.
Code Compliance: British and European Standards BS. EN 13331.1 & EN13331.2, Australia & New Zealand Standards AS 4744.1:2025
High-strength steel construction delivers robust performance whilst remaining relatively lightweight. This makes overall transport, handling and positioning more practical on site, without compromising on durability or structural performance.
A robust, fully sealed working face creates a durable barrier between the excavation and the work area. Engineered to perform in demanding site conditions, while also providing long-term reliability through repeated use.
Twin extraction hook points provide a combined 27-tonne extraction capacity, giving site crews a strong and practical method for removing the shield from the excavation.
The lower and upper trench shields can be stacked while retaining full extraction capability, providing greater flexibility for deeper excavations. This allows reconfiguration of the system for different site conditions without sacrificing the ability to reposition the shields efficiently as work progresses.
A range of strut lengths is available for different trench widths, in both fixed and adjustable formats. This provides more flexibility to configure the shield around the excavation, instead of limiting it to standard dimensions.
Steel construction makes the system straightforward to assemble, maintain and repair using conventional welding methods - reducing downtime and extending service life.
A cutting edge on the lower panels helps the shield move more effectively and efficiently into position during installation.
