Roller container
A roller container is a container type that can be carried by trucks to be pushed to ground level by help of a hook and level arm with the container possibly sliding on steel roller wheels.
Its original usage was in the collection of bulk waste resulting in the creation of the DIN standards to be initiated by city cleaning companies. An additional part defines a transport frame mounted on specialized rail cars that allows easy intermodal transport for these container types.
Another important area is in the containerization of firefighting equipment used as swap body containers of fire trucks.
Solution removable transport containers in road and rail transport already appeared in the 1930s. Since 1934 in the Netherlands used the system for waste transportation and consumer goods under the name "Laadkisten". Permissible gross mass of the container was 3,000 kg (6,600 lb) and dimensions of 2.5 m × 2 m × 2 m (8 ft 2 3⁄8 in × 6 ft 6 3⁄4 in × 6 ft 6 3⁄4 in). Reloading held by dragging rope winch tow car. After World War II system has been introduced to communicate by trains between Switzerland and the Netherlands. On 14–23 April 1951 in Zurich Tiefenbrunnen under the auspices of the Club «Museum of Transport, Switzerland, Swiss Transportation" and Bureau International des Containers "(BIC) held demonstrations container systems aim to select the best solution for Western Europe. Present were representatives Belgium, France, the Netherlands, Germany, Switzerland, Sweden, Great Britain, Italy and the USA. the result of this meeting was the first after World War II European standard UIC 590, also known as "Pa-Behälter." this system has been implemented in Denmark, Belgium, the Netherlands, Luxembourg, West Germany, Switzerland and Sweden. Along with the gradual popularization of large container type ISO, system "Pa-Behälter" was withdrawn from use by the railways. In the 1970s began to be widely used for the transport of waste in the system of a car. :
The roller containers come in a larger variety for specific usages. For bulk waste a common type has additional impermeable doors on one side. There are low height containers that allow easy dumping of green care waste. There are squeeze containers that compress the garbage. Roller containers for construction waste need additional stability. The DIN standard does not define the height nor most of the other sizes - it concentrates on the hook for lifting the container and the wheels that allow sliding on the ground.
