SHIFTABLE CONVEYOR DEVICE FOR CONVEYING EARTH AND SAND

摘要

PROBLEM TO BE SOLVED: To outstandingly enhance an operation efficiency by smoothly carrying out a shift operation. SOLUTION: A sleeper 10 of a shiftable conveyor device has longitudinal front and rear end surfaces; both side surfaces 10a, 10b along a longitudinal axis direction; an upper surface 10c; and a bottom surface 10d. The sleeper 10 is disposed such that longitudinal axis direction becomes approximately parallel to a side shift direction and a rail is mounted to one end side of the upper surface 10c. A chamfered portion 12 is provided between both side surfaces 10a, 10b along the longitudinal axis direction and the bottom surface 10d. The chamfered portion 12 is constituted by a curved R surface having a predetermined curvature.
