The TuffTech Steel Heavy Duty Upper Trench Shield gives contractors a strong, versatile option for excavations that require a more compact shield. Built for demanding site conditions, it delivers the durability and reliability of the TT-77 range while giving crews greater flexibility across different trenching requirements.
Whether used on its own or combined with the TT-77 Lower Shield, the TuffTech Steel Heavy Duty Upper Trench Shield lets contractors configure trench protection around the job. Its shorter profile makes it well suited to applications where a full-height lower shield is not required, while the ability to stack the system provides additional flexibility as excavation needs change.
With multiple strut configurations available, the TT-77 Upper Shield can be adapted to suit different trench widths and working environments, making it a practical addition to any civil contractor’s trenching setup.

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.
