The invention discloses a mechanical lifting platform device convenient to operate and high in reliability. The mechanical lifting platform device comprises a handle (1), a platform cover plate (2), support cross beams (3), shear fork cross beams (4), angle steel supports (5), a fixing block (6), shear fork beams (7), a limiting pin (8), a spring (9) and a locking limiting block (10). The four upper and lower angle steel supports (5), the four front and rear support cross beams (3) and the platform cover plate (2) form a basic frame, and the four left and right shear fork beams (7) and the shear fork cross beams (4) form a movable lifting mechanism of the mechanical lifting platform device convenient to operate and high in reliability. The handle (1) is connected with the limiting pin (8) through a plug pin, the spring (9) is located in the fixing block (6), and the handle (1) drives the limiting pin (8) to compress the spring (9) to move between the fixing block (6) and the locking limiting block (10) to form a locking mechanism. The mechanical lifting platform device convenient to operate and high in reliability is simple in structure, convenient to operate, free of electrical components, high in moisture-proof and waterproof capability, and greatly improved in reliability and maintainability.
