Construction Elevator Device
The present invention includes machine room unit hoisters 9a, 9b, 9c by which a machine room unit 6 is suspended from a support member provided in a hoistway so as to be movable in an ascending/descending direction. The machine room unit hoisters 9a, 9b, 9c suspend the machine room unit 6 at suspension points 21a, 21b, 21c. The machine room unit hoisters 9a, 9b, 9c are provided, supported by the support member. When viewed from a virtual horizontal plane over the machine room unit 6, distances from a center G of gravity of the machine room unit 6 to each of the suspension points are substantially equal and the center G of gravity is positioned within a region enclosed by virtual straight lines connecting each of the suspension points 21a, 21b, 21c. When viewed from a virtual horizontal plane over a working platform 5, the respective suspension points 21a, 21b, 21c of the machine room unit 6 are positioned outside a contour of the working platform 5.
