Abstract

Upper wires (28) are provided between a base (12) and the hook (31a) of a crane (31), and lower wires (32) the base end portions of which are secured to the base are engaged with lifting member locking portions (11a) of a large-weight object (11), rings (32a) at the upper ends of the lower wires (32) being fitted around a mast (17) provided upright on the base. A slider (18) fitted slidably around the mast is pushed up by a first resilient member so that the upper end of the slider is flush with at least that of the mast in a no-load condition a slider lowering means (33) overcoming the resilient force of the first resilient member to lower the slider. A locking means temporarily fixes the slider lowering means with the slider in a lowered state, and an unlocking means disengages the locking means. The lower lifting members can be removed automatically from the large-weight object lowered to a predetermined place. A large-weight object of any shape can be lifted and lowered to a predetermined place without damaging the tension members, and an operation for hanging tension members on a hook of a crane becomes unnecessary.
