The
typical break in the treadmill decks is about two-thirds of the
length of the table, especially for users running on the treadmill
regularly.
The
breakage is due to the continuous stresses on the center of the deck,
which is particularly flexible as the deck is an integral component
of the damping system in domestic treadmills.
To
prevent breaking decks, it is possible to insert a reinforcement
metal bar (max. 3 mm thick) isolated from direct contact with the
table by means of rubber spacers.
Both
the bar and the spacers can be commonly found in hardware stores.
The
presence of the bar reduces the flexion of the board, avoiding
overextension and breakage. It is the same principle of reinforced
concrete. The bar can be fixed to the chassis or in some cases to the
deck itself, using in this case passing screws (thus crossing the
entire deck) and carefully inserting the screws in the center (the
rubber gasket seen at the center in the diagram below uses only
glue).
