Hook the common problems |
A common problem is the main hook Jack line decoupling, which is when the object bundling is not good, the angle between the jack line between more than 120 degrees, or the lifting hook is in lateral touch, heavy bottom are put when Jack would pull out from the rope hook. In addition, because the hook system is made of grey cast iron or cast steel materials, its brittleness, not bump resistant, easily broken, therefore, in the process of hanging objects, or if the narrow space of operator effect, pulley will suffer from collision. Once the pulley is damaged, will cause the cutting of the flange break of wire rope, wire rope and even cut off the accident. If the operator fails to give the hook pulley pulley can refuel, because the rotation is not flexible and lead to the bottom wear for a long time, the pulley will exceed the standard, half split, the hook will be released in the operation of the accident. Not only that, when the bottom wear increases, the amount of wire rope embedded deep increased friction resistance, junior high school, which leads to the wire rope embedding quantity deepen, increase the resistance, resulting in accelerated scrap wire brushed. Common problems of wire rope are generally more human factors. For example, the operator in operation, Caigang watts equipment and some equipment and buildings often friction, scratch, lead wire rope broken wire, outer local deformation; operation reel, wire rope on the drum of multi-layer winding hook often confused; circling in the air, the wire rope wire rope kink; long-term lack of oil on the surface of steel corrosion; the rope is often high temperature burn and high-voltage power lines and wire rope met burning is caused by accidents. The common problems are: the main brake spring brake adjustment is damaged or too loose, insufficient braking torque; brake shoes excessive wear exposed nails, lead to friction force is not enough, the brake brake weights; brake lever locking nut, lever movement, or the day off lever system stuck impact brake; brake shoes on the degree of clearance is not normal, some brake shoe clearance side open, as many as 2 to 3mm, while the other side of Gaoua is posted on the brake wheel, which speed up the brake shoe and wheel wear, when heavy load cannot be stopped. In addition, brake tight is negative, because when the brake open space is less than the normal value, the resistance of the brake wheel rotation will increase, often smell the burnt skin taste, when the friction thermal expansion, but will not brake the car accident. |
