chain block: Gear: Japanese technology of the symmetry high speed synchronous gear;The international standard gear steel makes it more wearable than the common ones,rotate more stably and need less pull force. Chain: The chain is more intensity and the welding at the joint is very subtle.It is treated withthe intermediate frequency furnace induction quenching according to ISO3007-1984 international standard chain specification;be capable of working at the sudden over load conditions;the hand chain feels better than before;this kind of chain hoist can be puled in various direction at an angle of. HOOK;The hooks are most intensitysafe hook which are made of high quality alloy steel,with special treatment.This can guarantee that the hook will not break,and will deform gradually under a sudden over-loaded. Limit switch devices: Fitted at both top and bottomends,the limit switch can switch off automatically to prevent load chain from running our. Componet:The key component are made of high quality alloy steel,the dimensions are strict and very component can exert its function. Hoist Body; The shape of the body is slim and beautiful,which makes it comply with the human system engineering,light and fit to be used in different areas. Painting:The painting method is advanced,and there is paint both inside and outside,No matter how long you use it,the hoist will still be like newly painted. Cover;The enclosure of the hoist is made of precision steel,which makes it looks deft but firm.
