Disclosed is a fixed and mobile-capable collapsible cart (100) that includes a plurality of wheel extend levers (102a, and 102b); a first engage surface (104); a first control surface (106); a first control carriage (108a); connection cables (110a, and 110b); swivel caster trunnions (112a); a locking dog (114); a locking catch (116); and casters (118, and 120). The wheel extend levers (102a, and 102b) are pulled to facilitate the first engage surface (104) to contact with the first control surface (106) on the first control carriage (108a) when the fixed and mobile capable collapsible cart (100) is in a retracted state. When the wheel extend levers (102a, and 102b) are pulled farther, the first control carriage (108a) rotates and pulls the connection cables (110a) causing the swivel caster trunnions (112a) to rotate towards an extended position. The locking dog (114) snaps over the locking catch (116) present on the end of the first control carriage (108a) when the swivel caster trunnions (112a) are in the extended positions to lock the casters (118) into the extend position. The wheel extend levers (102a, and 102b) are released after snapping of the locking dog (114), over the locking catch (116) and a hand lever torsion spring (201) return to a home position.
