GRT's hydraulic transport dollies are engineered and built specifically for the demands of challenging heavy haul and rigging projects. GRT uses 50 ton hydraulic transportation dollies to move modules weighing up to 4000-tons. Our dollies are shipped around the world in containers, are quick to assemble and perform well under adverse conditions. We use a combination self-powered, remote steered dollies and towed self steering dollies. GRT has configured arrangements of up to 48 units to move 1900 ton container cranes through busy ports, using carefully charted paths for movements in tight areas.
