substructure tarpaulin frame and rotation angle limiter

摘要

The invention relates to a canvas structure for a substructure, such as a truck, a trailer, a semi-trailer, a rail car, a dump truck or a container, comprising a cover frame and a tarpaulin made of material resistant to where the cover frame has a plurality of brackets (34) each having at the ends, in each case a carriage (32) which is movable along a conductor (20), wherein at least one arc (36) is hingedly connected to each pair of opposing carriages (32; 32 '), said arc forming with an arc (36) of an adjacent carriage pair (32), a tarpaulin folding aid, the arches (36) of the canvas folding aid being attached to each other. a tarpaulin structure permitting secure coverage of a substructure while obtaining a low intrinsic weight according to the invention, because the connected arcs (36) comprise a rotation angle limiter (38) which allows only one turning limited arch (36).
