Abstract: A hoisting device for the transfer of formwork and other construction materials that does not require cutting and welding of the guide rails for assembly and disassembly on site, yet does not pose the difficulties of transporting and handling the fixed span of a full length guide rail. The hoisting device also offers advantages in the transfer materials along floors of buildings that do not follow a vertical line, and in allowing the hoist car to access “green” slabs that are yet to attain full strength.
