グネットテープからなっている。(Embodiment) In the device of the present invention, 1 is a fixed mast, 2 is an ascending / descending mast that rises and falls while being guided by the fixed mast 1, and 3 is a fixed mast 1.
A fork (not shown) moves up and down by a hydraulic cylinder arranged in the rear part of the hydraulic cylinder 3 as the rod 3A of the hydraulic cylinder 3 expands and contracts. 4 is a bracket which is fixed to the outer circumference of the hydraulic cylinder 3 by tightening it on the outer circumference of the hydraulic cylinder 3 and has a tip 4A extending rearward of the lifting mast 2 and 5 extending to the tip 4A of the bracket 4. The fixed proximity switch 6, is composed of a magnetic tape detachably attached to the elevation mast 2 at a predetermined interval from the proximity switch 5.
昇降マスト２が上昇してマグネットテープ６が近接スイ
ッチ５の直下に到達すると，近接スイッチ５が作動し，
所定の動作例えば昇降マスト２の上昇動作が停止する。When the lifting mast 2 rises and the magnetic tape 6 reaches directly below the proximity switch 5, the proximity switch 5 operates,
A predetermined operation, for example, the lifting operation of the lifting mast 2 is stopped.
（効果） 本考案装置は，上述のような構成であるから，下記のよ
