Vertical aluminum shoring walers

Vertical aluminum shoring walers are compact trench system of lightweight, which is used where it is not necessary to trench whole excavation. Frames are easily transported; their installation in the trench is very fast and can be done from the edge of the excavation by one person within a few seconds. Hydraulic expands, placed one above the other, are interconnected. The pressurization occurs simultaneously through hand pumps a mixture of water and hydraulic fluid. In deeper excavations frames are fitted side by side with displacement below the excavation.
