Abstract

PURPOSE: To facilitate movement at fields by freely letting even a large-scale crawler crane travel at narrow places when trevelling, and to prevent a shaking phenomenon by working the empty weight of a crane body as a weight when operations.
CONSTITUTION: A crawler crane is constituted by installing an upper turning body B provided with an operation chamber E, crane driving gears F, a gantry, etc. onto a lower travelling body A equipped with left-and-right crawlers in a turning- free shape. In this case, a travelling body frame is composed from a cylindrical or truncated cone-like round drum 1 supporting the upper turning body B, square pipes 2, which are pierced through a flank portion of said round drum 1 from a center of turning and are combined in a radial or X-shaped from, and left-and- right crawler frames 5 supported to the noses of the pipes 2 and produced by using two parallel plates 3, 4 and main material, and outrigger beams 18, which are expanded by means of oil pressure cylinders 19 and which noses are provided with floats 21, are internally installed into said square pipes 2.
