TOOLS FOR THE JOB

In this fourth article in the series on labour-intensive construction, the vast range of tools and equipment which are, or could be, used on labour-intensive civil engineering projects is examined. It is suggested that the enormous spread of hardware used in labour-intensive works can vary from the simple end of the range, as represented by such items as handbaskets and crowbars, to an upper limit of perhaps a powered roller, ropeway or light railway. Three broad classifications of hardware are discussed, that used for excavating and loading; that used for transport and that used for compaction. It is suggested that the last falls into three categories; equipment intensive, using purpose - built self - powered machinery; semi-equipment-intensive, using simple equipment drawn by tractors or animals; and labour-intensive, using hand-operated equipment. The principal distinguishing characteristics of such tools and equipment are discussed, together with the use of animals as load carriers and as a source of machine power. Illustrations show the use of tools and animals in varying labour-intensive situations, and a summary is provided of the relative tractive efforts and load capacities of animals. Some figures on comparative costs of operation are provided as a guide to economic costs. /TRRL/
