Patent KR-19990064057-A (KR)
IPC: B60P1/64
Filed: 1996-10-09
Abstract: The novel invention proposes a combination of variable containers and a chassis or variable platform (10) and various items of superstructure for transporting light, bulky bulk products. The variable platform has a short-travel raising and lowering device (11) and is firmly secured to the chassis. A container, for example, can be moved from the stationary to the transportable state very rapidly. The superstructure or the container may be either supported on the floor by four supports or lowered on the chassis via suitable bearing points. In the majority of cases the exchange is made with the variable platform and can be performed by a single person without further aids like a crane or fork-lift truck. The superstructure may be in the form of an open or closed container. Light, bulky products, e.g. insulating material, may be transported according to the invention in the same manner e.g. building rubble using prior art interchangeable skips.
