(2,438-4,267 mm) OD tunneling and pipe jacking applications, Akkerman Excavator Shields are a proven partner. Excavator Shields differ from the Tunnel Boring Machine (TBM) in that they do not have a cutter head or rotating drum, and excavate spoils with a backhoe-type excavator. The excavator and control console easily transfer between different sized shields. Excavator Shields are appropriate for traditional pipe jacking, liner plate and ring-beam and lagging tunnel building. The EX 50 Excavator, housed inside the shield, assists in the removal of obstacles and spoils at the face of the bore between the sand shelves. Operators control this fully steerable, laser- guided machine with joysticks and foot controls. For loose soil conditions, optional closeable hydraulic doors prevent subsidence from entering the jacking can. Like all Akkerman TBMs, the Excavator Shield is powered by hydraulics and guided with a laser system. Excavator shields perform with our 5000 Series Pump Units or a multiple cylinder jacking system.
