Abstract
ABSTRACT
A top wire 28 is set between a base 12 and a hook 31a of a crane 31. a bottom wire 32 whose foundation end is set to the base engages with a hoisting member engagement portion 11a of a heavy load 11, and a ring 32a at the front end of the wire 32 is fitted to a mast 17 erected on the base. A slider 18 slidably fitted to the mast is raised by a first resilient body so that the top of the slider fits at least the top of the mast and slider lowering means 33 lowers a slider by overcoming the resilient force of the first resilient body. Locking means temporarily fixes the slider lowering means while the slider lowers and unlocking means unlocks the locking means.
It is possible to automatically dismount a bottom hoisting member from a heavy load downed at a predetermined place.
Moreover, it is possible to down a heavy load with any shape at a predetermined place without damaging a tension member and disuse the operation for engaging the tension member with the hook of the crane.
