2 GB 40 Characterisation BAUER GB Line The BAUER GB 40 Hydraulic Grab Digging profits out of your projects Bauer s line of GB Hydraulic Grabs are a perfect marriage between our tried-and-true base machines with our state-of-the-art DHG V grab body. Our GB 40 is the newest realization of our smallest base machine, newly improved for increased performance. Since the introduction of a small-class grab in 1998, Bauer s team of world-class mechanical engineers have worked closely with our customers and partners to upgrade this classic machine. The GB 40 has the reliable mechanical, electronic and hydraulic systems that Bauer is known for, operating together in a perfect balance. But don t let its size fool you this machine packs a punch, especially with the standard free-fall function. Whether it s a dam, subway station, building foundation or any other diaphragm wall project, the GB 40 provides maximum efficiency in a compact package. With additional components like our B-tronic control system, and options like our TD4 Turning Device, you ll be able to deliver on time, even in challenging soil conditions. GB 40 GB 50 GB 60 Free-fall winch increases performance in harder soil conditions Reliable MDSG Mechanical Drum system minimizes service and maintenance requirements for winding system B-Tronic grab control system is easy to use and maximizes diaphragm wall quality 2 BAUER Maschinen GmbH 09/2016
