What is the difference between single speed and double speed of electric hoist, how to choose?
Single speed double speed refers to: lifting speed

Two-speed: There is an accelerating small motor next to the main hoisting motor and connected by a belt. When the main motor rotates, the small motor rotates faster than the main motor to achieve the purpose of increasing the lifting speed.
 
Single speed: only one hoisting motor
 
In normal use, single-speed wire rope electric hoist can meet the production needs. If you need to adjust the lifting speed during the lifting process to meet different lifting purposes, you need to cooperate with MD1 wire rope electric hoist, which is divided into slow Speed ​​and rapid rise, can achieve uniform speed stability.
 
Note on working environment of single speed or double speed electric hoist:
Scope and working conditions: MD1 electric hoist is suitable for working in an environment with a temperature of -20 ° C to 40 ° C, a relative humidity of ≤85%, an altitude of less than 1000m, and no risk of fire, explosion, or corrosive media. It is forbidden to transport molten metal, which is toxic , Flammable and explosive items. The applicable power source is AC three-phase, 50Hz, 380v; the working type of this product is intermediate, and each time the working level of the mechanism is increased by one level, its rated lifting capacity must be reduced by 20%.
