Fail-safe load support system

A structural fail-safe support system for storing vehicles comprising:

• a stationary structure supported by the ground,
• an inclinable rigid structure supported by said stationary structure,
• a two-bearing axle on said stationary structure providing a pivot for said inclinable rigid structure, which does not change shape when tilted,
• two parallel independent means to rotate said inclinable rigid structure about the said axle on the said stationary structure providing a fail- safe characteristic if one of the said independent means should fail,
• two parallel rectangular upper and lower decks on said inclinable rigid structure,
• a compression member which connects the center of the full span of the said upper deck with the center of the full span of the said lower deck dividing the two said full spans into four smaller spans which can support a greater total load,
• two tension members which connect the bottom of the said compression member to the front left and right corners of the said upper deck to provide compression forces on the said bearings of the said axle on the said stationary structure,
• two tension members which connect the bottom of the said central compression member to the left and right rear corners of the said upper deck to provide reaction forces for said two means which rotate the said inclinable rigid structure,
• means to measure the forces on each of the four said tension members,
• means to adjust the forces on each said tension member to values which constrain the said compression member from deflecting when the said upper and lower decks are subjected to loads,
• a calibration procedure to equalize the reaction forces on the two said axle bearings and the two said inclinable rigid structure rotation means,
• a secondary lift system to counteract the empty weight of the said inclinable structure, eliminating the load of the said empty weight from the primary said independent means for rotating the said inclinable structure, and
• an automatic apparatus for restraining the motion of a stored vehicle on the said inclinable deck.
