Abstract
In a hoisting/pulling device comprising a pinion gear 4, reduction gears 5a which are meshed with the pinion gear 4 and are rotatably mounted in a frame 1, and a load sheave which is interlocked with reduction gears 5b and is rotatably mounted in a frame 1, reduction gear bearings 8 are contiguously formed with a load sheave bearing 7 which is formed in the center of the frame 1. By making the distance between the axes of the reduction gears small and by forming the load gear and the load sheave integrally, it becomes possible to provide the hoisting/pulling device which can make the whole device compact and lightweight and can reduce the number of parts and man hours for machining the device.
