a) Manual Chain Hoist is a kind of hand lifting machinery that with simple structure, easy to take structure, also called Chain block.The lifting capacity is no more than 100t.
(2) Used in factory, mine, building site, dock, shipyard, warehouse to install machine, lift goods in short distance, especially to show it's advantages in open-air or without power working; also can matched with monorail car to make up lifting transportation car, applied in monorail transportation, manual single girder overhead crane and suspension crane.
(3) FEATURES
(4) In general
(5) Accord with international standards, safe and durable in use
(6) Great toughness, small size.light weight,easy to take.
(7) Small pulling load, high strength of machine parts.
(8) Advanced structure,good-looking appearance.
(9) Lifting goods without power.
(10) Working principle
(11) Lifting goods upside, clockwise pulling the chain, then sprocket run, pressing ratchet wheel and brake base as a body to rotate together, long axis rotate teeth gear, short axis and spline hole gear. Thus the lifting sprocket on the spline hole gear will drive the lifting chain to lifting goods stably.
(12) Lifting goods down, anticlockwise pulling the chain, the brake base will separate from the brake pad,ratchet wheel will stop under the influence of ratchet pawl, five long shaft lifting sprocket driven gear in the opposite direction, then lifting goods stably.
(13) The chain block adopts ratchet friction chip one-way brake, can brake under load condition, ratchet pawl mesh with the ratchet wheel under the influence of spring, make the brake work safely.
(14) Material
a) The main part adopts high quality alloy steel, the chain adopts 800Mpa high strength lifting chain, the material is 20M2,intermediate frequency quenching heat treatment, low wear, anti-corrosion chain; High strength hook, material is alloy steel, gesture type of hook make sure slow lifting to avoid overload, accord with CE safety standards, strength and durble in use, safety performance is high.
