A stress-indicating rope-tightening apparatus includes a rope-tightening unit and a stress-indicating unit. The rope-tightening unit includes a rotational joint. The stress-indicating unit includes two strain gauges disposed on two opposite sides of the rotational joint for measuring the strain in the rotational joint, a calculator for calculating the stress in the rope based on the strain in the rotational joint and a display for showing the stress in the rope.
