The Slide Rail Shoring Systems consist of individual components becoming a complete unit during excavation on site. A simple installation technique, slide rails and shoring plates are slideable to each other; the trench width remains constant during the entire excavation and back-fill operation. Much less pulling force is required to remove the panels, as there is no horizontal movement of the shoring and thus no pressure against the soil. Trench depth of up to 7.5 m can be achieved and big pits can also be installed, using these systems.
