The invention discloses a chain type electric hoist and a method. The chain type electric hoist comprises a speed reducing mechanism, a manganese steel chain and a lifting hook mechanism, wherein themanganese steel chain is installed in an inner cavity of the speed reducing mechanism in a penetrating mode through a synchronous gear; the lifting hook mechanism is arranged at the bottom of the manganese steel chain; the lifting hook mechanism comprises a lifting hook piece, a hanging shaft, a guide pulley, shaping blocks and uniform smearing mechanisms; the shaping blocks are arranged on the outer wall of the guide pulley at equal intervals; and the uniform smearing mechanisms are arranged on the front faces and the back faces of the shaping blocks. According to the chain type electric hoist, the shaping mechanisms arranged on the outer wall of the guide pulley at equal intervals are always clamped with the manganese steel chain in sequence in the moving process, are matched with the gravity of hoisted objects, gradually go deep along a chain hole, and expand and shape chain sections again which are pulled to deform; and the uniform smearing mechanisms act when the chain sections inthe X-axis direction are clamped and stressed, and slide close to the chain sections in the Y-axis direction so as to uniformly smear lubricating oil accumulated on the chain sections.
