PROBLEM TO BE SOLVED: To provide a safety device on a work table having hand posts disposed at four corners.SOLUTION: A work table is formed such that WL1 are satisfied, W being a width of an entrance (9) between a first hand post (4a) and a second hand post (4b). With regard to the width W, L1 is a length of a standing part (4u) extending above a top plate, L2 is a length of a base edge part (4d) extending below the top plate, and L is a total length of a hand post (4) that includes L1 and L2. A safety rod (11) is provided to be rotatable between a hanging posture and a horizontal posture that opens/closes the entrance (9). Rotary shaft means (21) of the safety rod (11) is pivotally fitted on movable shaft bearing means (12) provided movably in a vertical direction on the first hand post (4a). The safety rod (11) may rotate across a girder side edge (2d) of a top plate (2), by moving the movable shaft bearing means (12) upward.SELECTED DRAWING: Figure 5
【課題】４隅に手掛かり棒を配置した作業台の安全装置を提供する。【解決手段】第１手掛かり棒(4a)と第２手掛かり棒(4b)の間の乗降口(9)の幅Ｗに対して、天板よりも上方に延びる起立部(4u)の長さＬ１と天板よりも下方に延びる基端部(4d)の長さＬ２を含む手掛かり棒(4)の全長ＬをＷ＜ＬかつＷ＞Ｌ１に形成した作業台において、前記乗降口(9)を開閉する垂下姿勢と水平姿勢の間で回動自在な安全ロッド(11)を設けており、該安全ロッド(11)の回動軸手段(21)を第１手掛かり棒(4a)に上下方向に移動自在に設けられた移動軸受手段(12)に軸着しており、該移動軸受手段(12)を上向き移動することにより、安全ロッド(11)が天板(2)の桁側縁(2d)を横切って回動することを可能とする構成である。【選択図】図５
