To improve the safety and save labor of work.SOLUTION: A heavy load lifting device 2 includes a chain block 4 mounted on a support frame 3 to move up/down a rail holding tool 10 for holding a rail R, an electric motor 5 for driving the chain block 4, a control panel 6 for controlling the driving of the electric motor 5, and a pendant type operation switch 21 that is freely portable to transmit a command signal to the control panel 6 by radio. The heavy load lifting device holds and moves up/down the rail R. The control panel 6 is arranged to be separated from the support frame 3. An operator can perform lifting operation by using the control panel 6 and the pendant type operation switch 21 with simple operation at desired timing in a safe place apart from a site only by holding the rail. In addition, the lifting operation can be performed at a desired height and a desired speed.SELECTED DRAWING: Figure 1

    【課題】安全性の向上と作業の省力化を図る。【解決手段】重量物吊上装置2は、支持枠3に取り付けられ、レールRを把持するレール把持具10を昇降させるチェーンブロック4と、チェーンブロック4を駆動する電動モータ5と、電動モータ5の駆動を制御する制御盤6と、制御盤6に無線を通じて指令信号を送信する持ち運び自在なペンダント型操作スイッチ21とを備えて構成され、レールRを把持して昇降させる。制御盤6は、支持枠3から離隔されて配置される。制御盤6とペンダント型操作スイッチ21とにより、作業員は、レールを把持しさえすれば、現場から離れた安全な場所で、簡単な操作により昇降操作を所望のタイミングで行うことができ、しかも、所望の高さ、所望の速度で昇降させることができる。【選択図】図1
