SOFT TRIPLE FOLD TONNEAU COVER

Definition: A protective cover plate made of multiple rigid hard panels (steel plate, aluminum alloy, fiberglass, carbon fiber, etc.) hinged together and foldable inward/sideways for storage, used to close the engine compartment opening; Different from soft tarpaulins, the cover itself has structural rigidity, can withstand loads when closed, and is dustproof and waterproof.
Two common application scenarios: * * construction machinery/special vehicles * *, * * ship engine compartment * * (ordinary car engine covers are generally one-way flip up, rarely called folding)
structural composition
1. Hard cover plate: divided into multiple independent rigid plates, with no deformation of a single plate;
2. hinge components: hinged between sections to achieve folding and stacking;
3. Drive mechanism: manual strut/hydraulic cylinder/electric push rod;
4. Locking+sealing: mechanical lock buckle, rubber sealing strip, waterproof and dustproof;
5. Limit and safety devices: anti fall insurance, travel limit.
Advantage
-Strong rigidity, impact resistance, trampling resistance, sun aging resistance, far superior to soft canopies;
-Folding storage, no need for large radius flipping space after opening, suitable for narrow layout;
-Good sealing, rainproof, dust-proof, and oil splash proof;
-The surface can be coated with anti slip and anti-corrosion coatings.
shortcoming
-There are many hinges and hydraulic components, with complex structures and high costs;
-High self weight; The hinges, pins, and sealing strips are vulnerable parts that require regular maintenance;
-Folding storage still requires reserved stacking space.
Typical applicable equipment
Excavators, loaders, generator sets, mining special vehicles, ship engine rooms, yacht engine rooms, large air compressor power cabins.
Different from a regular flip up hood
-Ordinary car engine hood: * * single rigid plate, one-way upward opening, no segmented folding * *;
-Hard folding hatch cover: * * Multi segment splicing, folding and stacking * *, suitable for scenarios with large openings and limited space.
