PORTABLE HOIST UNIT AND HORIZONTAL MEMBER DISMANTLING METHOD
PROBLEM TO BE SOLVED: To provide a portable hoist unit with high general-purpose properties, which can be installed in a compact general-purpose construction work vehicle, and a horizontal member dismantling method using the portable hoist unit.SOLUTION: A hydraulic jack, which has a tip of a rod provided with a pulley having a rope looped thereover, is adopted as hoist means of a portable hoist unit, and expansion/contraction of the hydraulic jack is transmitted to a bed via a rope. Thus, a long movement distance of the bed in a height direction is secured, and weight saving is achieved.SELECTED DRAWING: Figure 1
【課題】コンパクトで汎用的な工事用車両への据え付けが可能な汎用性の高い可搬式昇降装置と可搬式昇降装置を用いた水平部材の解体方法を提供する。【解決手段】可搬式昇降装置の昇降手段に、ロープが掛けられた滑車をロッド先端に備えた油圧式ジャッキを採用してロープを介して前記油圧式ジャッキの伸縮を前記ベッドに伝達することで、ベッドの高さ方向の移動距離を大きく稼ぐとともに、軽量化を図る。【選択図】図１
