QTZ145F10 Tower crane There are two main types of tower crane in general use; Self Erect Tower Crane This is a tower crane that is designed to be easily and rapidly transported and erected. Some of them carry their own generator and are therefore completely self contained. Assisted Erect Tower Crane This type of tower crane is usually larger with a greater lifting capacity than the Self Erect. Its design calls for it to be builton site, piece by piece, often with the assistance of a mobile crane, hence its name 'Assisted Erect'. Both yypes of tower crane can be found in operation with a variety of jib configurations, all designed to provide a specific type of lifting service to sites where the lifting requirements and the environment produce different demands.
