<P>PROBLEM TO BE SOLVED: To provide a hoisting device, capable of easily inclining a hoisted load in hoisting to carrying in and out the hoisted load through a narrow opening. <P>SOLUTION: A heat exchanger 100 is hoisted by two endless wires 14 attached to a balance 12 of a crane 20 and two endless wires 18 each provided with a hydraulic cylinder 16. When a piston 17 of the hydraulic cylinder 16 is extended, the heat exchanger 100 is easily inclined. The extension quantity of the piston 17 is adjusted to adjust the inclination of the heat exchanger 100, and the heat exchanger 100 is carried out through the narrow opening 112. This hoisting device 10 can have a simple structure without increase in size and weight since it is constituted by the two endless wires 14 and the two endless wires 18 provided with the hydraulic cylinder 16. <P>COPYRIGHT: (C)2012,JPO&INPIT |
