The electric block is slow type why two electric motors, a motor not ok?
Do you mean how fast speed Of course to have two motors, electric hoist on just ordinary motor cannot control So is equipped with two motors.
Electric hoist simply as a motor can rise and fall of goods, but usually electric hoist used for the rise and fall goods and lateral movement in a different position, the goods will need two motor to run.
Through proper design is also an ordinary motor can realize two speed speed, it is not necessary to have two motors, such as two reducer, but at the moment, as if no such design, I want to know whether such a design defect
