To make up construction works is necessary to move high quantities of
different materials such as aggregates, cement, steel, concrete, plasters or
precast elements from a place to another.
Construction transportation has the following particularities:
„«The transported products have different shapes, dimensions and densities;
„«The transportation means are loaded only in one way from the producer to
the site, their returning being empty;
„«The transportation distances can be small (several meters) or very great
(up to hundred of kilometres);
„«Usually there are two main directions in transportation: horizontal
transport and vertical one.
The construction products transportation represents a complex process that
implies loading, circulation and unloading.
By taking into consideration the characteristics that influence the
transportation, the materials can be:
„«Powdery (consisting of fine particles) materials such as cement or plaster;
„«Granular materials such as sand, gravel or soil;
„«Regular small materials (bricks);
„«Uneven (not even or uniform as e.g. in shape or texture) small materials
„«Big regular or uneven materials (metallic profiles, precast elements);
„«Liquid materials of different consistency (water, gas, oils, hot bitumen, and
All these materials can be transported:
„«Horizontally along big distances, between storehouses or from a warehouse
to a site (H1);
„«Horizontally on small distances from the site storehouse to the lifting
„«Vertically, to lift or to descend different materials (V1);
„«Again horizontally on small distances to reach the working point (H3);
„«Combined (both horizontal and vertical) directly from the site storehouse
to the object if the lifting devices can (C1).
