PROPULSION MEANS FOR HOISTING SYSTEMS ABSTRACT OF THE DISCLOSURE The invention concerns a novel concept of "rail-less" propulsion of hoisting equipment, namely to provide two parallel rows of discrete, spaced, glidingly supporting- points on which the end-beams of a crane or the like are adapted to slide, rather than by wheels on a pair of continuous rails. The gliding supports are placed on top of series of equi-distantly spaced columns and the end-beams length is at least twice the distance between adjacent supports. Various kinds of driving systems are described.
