Abstract
The utility model relates to a safe walking board for a movable-arm tower crane cargo boom. The safe walking board comprises a first knuckle arm cone of the movable-arm tower crane cargo boom and a regular rectangle truss; and the safe walking board is characterized in that a passage (2) which is 500mm wide is remained in the middle of the upper plane of the cone, two sides of the cone are welded with a cross web member by a web member respectively, and a steel screen is welded on two angle steels by the lower plane of the cone, thus the safe walking board (1) is formed, the width of the walking board is 400mm, and the structure is convenient for a maintenance man to walk safely. By adoption of the structure, the safe walking board is novel in structural design, safe, reliable, economic and practical.
