Electric  Wire rope hoist  electric hoist in terms of relative compact, easy to use, as opposed to higher efficiency in terms of  manual hoist   used for lifting smaller higher altitude in the workplace, the use of electric hoist encountered during the most common problem is that the brake brake is not solid, the following analytical encountered such a situation you how to do?
1, the adjustment of the electromagnetic armature. Will be a wrench to pull the lock nut with another wrench to turn the brake spring plunger l, square head, according to the provisions to adjust the stroke solenoid armature stroke.
2, the spring working length adjusted. Whole tone nut, the nut with a wrench clockwise, compressing the main spring, allowing increased elasticity, so that when the brake shoe will hold even tighter.
3, the brake shoe and the brake wheel gap adjustment. The solenoid armature to push on a core, then shot actuator release, and then adjust the screw, the left and right wheel and brake shoe clearance equal.
4, the electric hoist mounted on the vision, flat place.  lift hoist  heavy objects should be installed at a distance of 15m outside.
5, hoist electrical equipment should be grounded, electrical switches should guard.
6, the electric hoist firmware must be solid. According to the room situation, using anchor fixed or pit anchors. When traction is large, but also in front of the elevator support.
7, such as raising the machine to use a longer time, you should erection of canopy to prevent rain and wet hoist and hoist base underlay to sleepers.
