12.4.5 Self-Erecting Mobile Supporting Structure

Self-erecting mobile supporting structure are designed with the provision of hand winching mechanisms which allow the structure to be assembled horizontally on the floor. Operation of the winches pulls the side members of the ‘A’ frame supports together until the mobile supporting structure is in its operating position. Additional locking structural components are then inserted makingthe structurerigid. This design isusually available in the highercapacities from 2 tonnes upward. (See Figure 12.4.5-1 )
