Product introduction
Double speed wire rope electric hoist is MD1 wire rope electric hoist, it has two speed, 8m/min, 0.8 m/min, double speed 7m/min, 0.7 m/min, double speed 3.5 m/min, 0.35 m/min, according to the specific use of different can choose the relative two-speed wire rope electric hoist, the product design is reasonable, the price is fair, widely used in factory assembly lines, workshop production lines, vehicle handling, machinery manufacturing and other places.
Performance characteristics
The slow speed of the two-speed electric hoist is one tenth of the normal speed. The main motor is normal speed and the secondary motor is slow speed. It is composed of auxiliary motor, intermediate gear and main motor brake disc with gears, which are independent slow mechanism. We have already talked about MD type electric hoist brake before, they generate friction when the brake wheel of the main motor brakes and are connected into a double-motor unit.
