起吊前的准备工作；将上吊钩悬挂固定的吊点上，将铝合金手扳葫芦调至空档，旋转手轮，调节链条的长度，使下吊钩能够钩住重物。

The preparation work before lifting is done. The hanger hangs and hangs the fixed hanging point, the aluminum alloy hand hoist is transferred to the neutral gear, the rotary handwheel is adjusted, and the length of the chain is adjusted, so that the lower hook can hook heavy objects.

起吊过程中的操作：将重物向上提升时，将拨块组件扳至位置牌的“上”位置，然后往复的扳动手柄，随着手柄的扳动，重物可平稳的实现上升。

Operation in lifting process: when lifting the heavy object upward, pull the block assembly to the upper position of the position card, then pull the handle reciprocally, and with the pull of the handle, the weight can be smoothly increased.

当重物下降时，将拨块组件扳至位置牌的“下”位置，依旧扳动手柄，便可实现重物的下降。

When the weight is down, the block component is pulled to the "lower" position of the position card, and the handle is still pulled, and the drop of the weight can be realized.

通过上述的说明，相信大家已经知道了如何使用铝合金手扳葫芦进行提升和下降重物了。

Through the above description, we believe that you have already known how to use the aluminum alloy hand squash for lifting and lowering the weight.
