TWF Trench Boxes Type 600
Updated: 26.05.2026
Trench Boxes are the worldwide most used mechanised shoring system for trench depths up to 4 m. No other shoring equipment is faster and easier to install. Base and top plates are available of different height, length and plate thickness to meet a wide range of site conditions and with various spindle extensions trench widths up to 4.26 m can be reached. All our trench boxes are approved by the German TBG and meet strongest safety standards.
