The invention relates to a force-bearing type rope ladder. The force-bearing type rope ladder comprises two side ropes and a plurality of steps connected between the two side ropes and is characterized by also comprising a ladder-shaped hollow protective jacket, wherein the two side ropes penetrate through the hollow protective jacket and intersect at a crosspiece part of the hollow protective jacket, and the steps are arranged on the outer wall of the crosspiece part of the hollow protective jacket in a sleeving manner. The force-bearing type rope ladder has prominently substantial characteristics and significant progress that 1. the bearing capacity of the rope ladder is improved by arrangement of the protective jacket through which the ropes pass and the steps sleeved outside the hollow protective jacket, and therefore the rope ladder is suitable for the change of an insulator, the insulator does not need to be treaded directly, and the operational reliability and the safety of the rope ladder are improved; 2. the hollow protective jacket is a flexible body with high toughness and high stretching resistance; 3. the two side ropes are used for providing enough strength protection for avoiding falling off of the conducting wire and improving the operation periphery safety and the operation safety; and 4. the force-bearing type rope ladder can be smoothly fastened on a conducting wire through the combination of a hasp and a fastener.
