AMPHIBIOUS CRAWLER CRANE

摘要

An amphibious crawler crane (100) includes: an arm support (1), which is supported on a chassis (2) of the crane and is composed of a plurality of detachable booms connected in turn; a crawler walking device (5), which is disposed under the chassis of the crane; a support device, which is detachably connected to the chassis and supports the whole weight of the crane in working, and which comprises cantilever beams (3) transversely extending from the chassis and radially distributed; hollow barrel-shaped bases (4), the lower end of each of which has an opening, and the upper end of each of which is closed and detachably connected to the free end of one of the cantilever beams. In working, the hollow barrel-shaped bases bear the whole suspended weight, and the lower end of which extends into soft beach regions or shallow water regions, so as to support more stably and operate simply.
