PROBLEM TO BE SOLVED: To provide a lifting type platform safety fence which enables simplification, miniaturization, and cost reduction of a strut structure, further an increase in distance between struts, by strengthening rope tension in a descent state that needs rope blocking force, and by weakening rope tension upon lifting up and down to alleviate lateral force applied on the strut.SOLUTION: A lifting type platform safety fence is configured so that the tension of a rope 13 suspended by lifting type struts 11A, 11B and lifted up and down by the lifting movement of a strut movable part 11-2 of the lifting type struts may be adjusted to proper values in accordance with positions of a rope with a tension drive mechanism 14 provided in coupling parts on both ends of the rope. The tension drive mechanism 14 adjusts and controls rope tension to proper values in accordance with height positions of the strut movable part, that is, rope height positions when the strut movable part 11-2 is lifted up and down.SELECTED DRAWING: Figure 1
【課題】ロープ阻止力が必要とされる下降状態でロープ張力を強くし、昇降時にはロープ張力を弱くして支柱に掛かる横方向の力を軽減し、支柱の構造の簡易化、小型化、コストダウンを図り、さらに支柱間の距離を拡大できる昇降式ホーム安全柵を提供する。【解決手段】昇降式ホーム安全柵は、昇降式支柱11A,11Bによって懸架され昇降式支柱の支柱可動部11−2の昇降動作によって昇降するロープ13の張力を、ロープの両端の連結部に設けた張力調整機構14によって、ロープの位置に応じ適正値に調整するように構成される。当該張力調整機構14は支柱可動部11−2が昇降するとき当該支柱可動部の高さ位置、すなわちロープの高さ位置に応じてロープの張力を適正な値に調整制御する。【選択図】図1
