A forklift is also used with wheels to lift or lower heavy objects.
It is still quite inconvenient.
Using a gear set for transmission is not flexible enough.
Especially when trying to lower a heavy object, the operation is too troublesome.
The current method is to reduce the motor power, so the power is decreased, and the heavy object falls due to lack of support.
Additionally, there is a braking device; when the handle is pushed, the falling object will hover in mid-air.
From Ma Lin's perspective, the use of these machines is very inconvenient.
But he couldn't think of a way to improve them.
He hopes for a very convenient and flexible way of power control.
Like the boom of a crane, it should rise when you want it to rise, descend when you want it to descend, and stop when you want it to stop.
It seems that using a gear set makes it difficult to achieve such things.
Exerting force upwards, but the result is that the object falls downwards, it's just impractical.
