Attachable cart system and method

A method of coupling a cart to a secure receiver:

• the cart is placed in position with a mount secure coupling mounted on a top deck assembly of the cart substantially aligned with the secure receiver;
• a hydraulic pump foot pedal coupled to a hydraulic cylinder pump in an undercarriage assembly of the cart receives pumps from a operator to elevate the mount secure coupling above the secure receiver;
• and
• a hydraulic release lever is activated to release pressure in the hydraulic cylinder pump to lower the mount secure coupling onto the secure receiver and cause the undercarriage assembly to rise.

A method of decoupling a cart from a secure receiver:

• a lever is activated to unlock a secure coupling lock assembly through a connecting rod extending a width of a top deck assembly which pulls a latch bolt out of an opening of the secure receiver and allow the cart to rise above the secure receiver;
• force is received by a hydraulic pump foot pedal to deploy the undercarriage assembly and components of the undercarriage assembly including an axle rotation cams, the stow axles and a plurality of wheels will rotate;
• and
• an axle lock trigger and wheel locking pins will reset to locked and prohibit the stow axles from rotating when an undercarriage assembly including the plurality of wheels are extended and the axle lock trigger is no longer deflected by the secure receiver.
