Features: The lifting chain is made of G80 galvanized manganese steel with high intensity, strong toughness and long service life. The chain anti-drop ring would prevent the chain from being pulled out when you pull the chain freely to adjust the hook position. When the up and down switch is in the middle, the chain can be pulled freely to adjust the hook position. Set the up and down switch to the corresponding position and rotate the handwheel to the right until the chain is tight, then start working. The handle is covered with non-slip rubber material with special texture, it is ergonomic and makes this lever chain hoist easier to use.
