Abstract:
Construction productivity is effected from materials handling method on site. This research
is to develop a vertical lifting equipment for construction materials to improve productivity in
constructing 4 12 meter height building. Productivity of transporting brick, cement bag, ceramic
tile, gypsum board, and sand by traditional methods, which are lift, winch, and labor, are studied.
Productivities in transporting the five type of materials by using the developed equipment are
compared to the traditional methods. It is found that construction productivities using the
developed equipment in transporting ceramic tile, gypsum board, and sand are better than using
winch and labor in terms of kilogram per hour and kilogram per meter. However, the construction
productivities in term of kilogram per baht using the developed equipment are better than using
all traditional methods for every studied mate
