[0027] Furthermore, a rope reel assembly 112 is installed between the spring crown 115 and the torsion spring end rope reel 104 and on the outer end surface of the connecting shaft 120. The rope reel assembly 112 and the connecting shaft 120 are connected by a flat key 111. Further, a spring rope reel housing 113 is provided on the outer end surface of the rope reel assembly 112.
