A method and apparatus that reduce release of dust generated during rotary dumping of rail cars in a dumping facility. The method includes removing dust laden air from a space bounded by a backside airflow diverter, a rotational frame, a first baffle and a second baffle while the rotational frame is rotating with a rail car by drawing the dust laden air through a secondary air intake that passes through the backside airflow diverter into a backside hood. A dust control apparatus includes a diverter, overlying a backside hood having a concave curved upper surface; and at least one secondary air intake positioned to pass through the diverter being located approximately where pressure in the backside hood remains neutral or negative relative to a pressure even there is a transient increase in air pressure in a lower portion of the backside hood.

The invention relates to a system for turning a cargo carrier (3) with the purpose of discharging the same of cargo, which system comprises a transport device (1) having a chassis, a cargo carrier (3) loosely carried on the chassis and provided with engagement points (6a, 6b), a first turning device (10) disposed to engage with the engagement points (6a) of the cargo carrier as well as to actuate the cargo carrier for the turning of the same, and a second turning device (11) disposed to engage with the engagement points (6b) of the cargo carrier at the same time as the first turning device actuates the cargo carrier, members for the control and actuation of at least the first device (10), and members for the correct positioning of the cargo carrier (3). Upon actuation of the first device (10), the cargo carrier is disposed to tilt so that the engagement points arranged on the second side of the cargo carrier will engage with the second turning device (11). The invention also relates to a transport device and the use of such a transport device in the system.
