    Construction Materials Transportation

    The day-to-day transportation in the construction industry requires activities in severe terrain and load. Therefore, the choice of vehicle and equipment must be careful in terms of load and implement. The dump bodies and concrete mixers are the most used options, largely found in field.

    Dump Bodies

    The dump bodies (also known as bucket dump trucks) are the most common equipment for the transportation of various building materials. Generally, it takes a short distance chassis with wheelbase. The reduction of the rear axle must be appropriate for ground conditions and topography. The installation of a power outlet in the exchange is required to drive the hydraulic system of tipping bucket.

    The load capacity and volume of the bucket to be compatible with the specific weight of material to be transported. Typically, the specific gravity of approximately 1.5 tonnes per cubic meter includes the average value of the primary materials used in construction (sand, gravel, stones, earth... - dry material).

    Concrete Mixer Trucks

    The concrete mixer truck is a drum mixer or balloon constructed of steel, high resistance to abrasion and corrosion. Two helices in the body of the drum to perform homogenization of the concrete. A special hydraulic pump is driven by motor vehicle. It is transmitted through a planetary gear unit installed in front of the drum, with the carriageway which operates on rollers mounted on the rear structure, situated on the auxiliary chassis.

    In front, the mixer has a water tank pressurized by the brake system of the vehicle washing drum. Already in the rear, are located the spout load, the discharge chute at the command of the mixer and a deck and stairs to the barrel for viewing of the load.

    Tips on Unloading your Cargo

    In landfills with a body and semi-trailers, tipping, you should take some precautions, especially if the load is adherent. In this case it will display resistance to sliding, as with the wet clay, mud, damp earth, garbage... To operate this type of material, it is necessary that the hydraulic system provides a dump angle of around 50 degrees.

    Another important caution is in operation as regards the position of the vehicle when his discharge. It should be placed in the flat and level, as there is danger of tipping due to the displacement of the center of gravity of the load, as shown in the image below. load.
