Talking about the practical operation of the hand hoist

As a light and small lifting equipment, the hand hoist in the operation is also required to have certain skills, and in the use of the hand hoist lifting operation and the hand hoist has a great difference, which is based on the appearance of the two structure and drive mode differences, the following Chenghua manufacturing to take you to understand about the operation of the hand hoist.

First of all, we should be very clear that the drive mode of the lever hoist is to achieve the purpose of lifting by repeatedly pressing the hand-held handle, but in the process of repeated pressing will face such a problem, because the lever hoist is in a suspended state, when pressing the handle will exert a lateral force, and then drive the whole lever hoist to swing together, affecting the lifting operation. It is also very inconvenient to operate, so how to solve this situation?

In fact, the swing of the lever gourd can be solved by some simple changes in the drive, we need to figure out the reason for the swing of the lever gourd, because it does not exert a vertical downward force like the hand pull gourd, and there is no external force in the initial stage of pulling the handle to offset this lateral force, resulting in the swing of the lever gourd. In fact, we can completely limit the lateral swing of the lever hoist.

When operating the lever hoist, we only need to use one hand to press the handle, the other hand to hold the "neck" of the lever hoist, that is, the position below the upper hook, through this way to limit the lateral thrust, so as to maintain the stability of lifting, when the lifting chain is tense, the whole of the lever hoist will be subject to downward load, This force cancels out the lateral thrust, and we can withdraw the "neck" hand.
