Abstract: The present invention relates to a construction climbing system with improved structural stability and, more specifically, to a construction climbing system with improved structural stability, and having an improved form, the system being capable of more stably operating the attachment and detachment of a gang form provided in the climbing system without shaking, enabling the vertical movement of the climbing system to be smooth without stopping so as to ensure structural stability, and enabling a working space of an operator to be ensured as wide as possible by using an auxiliary extension platform, thereby enabling work stability of the operator to be improved.
