Hand chain hoists and trolleys with the tacit understanding

Chain Block chain through the hands clockwise pull, bracelet wheel rotation, the friction plate ratchet, brake pressure into one common rotation. Thus, the device is splined sprocket holes on the lifting gear driven lifting chains, heavy lifting so smoothly. Because their small size and other  chain block  own advantages result from its use is extremely widespread, chain hoists in addition can be used alone, can also be used together with the trolley wheel.
      The following is   manual hoist  unparalleled advantages: new design overload protection device, using concealed structure; chain hoists alloy material manufacture, and the surface hardening treatment, longer lifetime; chain hoists According to national standards, the same model without changing the part of ordinary hoist installation structure; hoist chain hoists used to effectively protect and prolong the life of the hoist.
      With Hand car (or push trolley) can be achieved hoists walking around in orbit.
