Do you have to do a hand winch? I want to hang 150 kg from the 1st floor to the 6th floor
You can shake it. The choice of speed is bigger than that. We can go to hangzhou juding industrial equipment.
If there's a pulley, it's still more difficult, and the adult man should be able to shake and consider the arm of the rocker.
There are many structures in the hand winch, one, one arm and one pulley; This structure can change direction, mainly by rocker arm length and drum diameter ratio (the ratio of torque and object distance) to achieve the purpose of energy saving, the advantage is speed faster, such as rural Wells with windlass; There is a pulley and a pulley, which is less than half the theoretical level of the first. 3, the combination of the pulley and the pulley, or the differential pulley, more labor-saving; Two or three are relatively slow to ascend; With gear or worm gear, the structure can easily be raised to a ton of objects, but may be slow to ascend. Adults should be swayed by the structure of the two, three, four. The first structure, such as a design that is not reasonable (such as a wobbly arm, or a thick roll), may not be able to shake the weight of a person with a light weight or arm force.
