Abstract
A hoisting device includes a first part movably connected to a running rail above it, and a second part suspended under the first part, and a hoist arranged between the first part and second part to lift and lower the second part. In addition, a scissors mechanism is arranged between the first part and second part to prevent the horizontal movement and twisting movement of the second part in relation to the first part. Such a hoisting device is advantageous, because the second part of the hoisting device may be lifted and lowered at the same time as the first part is moved without any notable swinging exerted on the second part.
