Base Dolly with Double-ended Steering

The GF-Base Dolly is the rolling base under GFM's cranes and jibs — GF-8, GF-9, GF-Multi Jib and GF-Mod Jib all build onto its mounting column. Each end steers independently, so the dolly holds a straight line, follows a curve or crabs around an obstacle with the whole rig standing on it. The telescopic push bar mounts at either end.

Hard rubber wheels come standard and pneumatic wheels are available; for rail work the corner receivers take 4x2 or 4x4 track wheels on 62 cm (24.5") track, and an adapter set widens the stance to 100 cm (39"). Hand-cranked levelling legs mount to the same receivers to set the column plumb on uneven ground. Machined and assembled in Germany by Grip Factory Munich.
