Thorns and bumpy is whets the blazers will shake after; Disasters, the difficulty is the blazers forward stepping stone on the road. Control the fate of the rudder is a struggle. Don't have a fantasy, not giving up a chance, don't stop the day efforts.
Crane parts is an important work in mechanical engineering, three parts of construction crane components common problem: when the crane operations, operations staff to carefully check the parts of the brake is working properly, whether card plug, brake shoe clearance fit, the brake surface is good, and whether the adjusting nut fastening. For brake of the lubrication should be 2 times a week, but be careful not to be stained with lubricating oil on friction parts. If the brake shoe, brake wheel, shaft, spindle, etc of wear quantity to exceed bid; The main spring, auxiliary spring break or plastic deformation; Cracks on the place such as brake; Magnetic brake, electric hydraulic pile of rod failure, due to the timely repair, not to run in spite of, to ensure safety. Crane refers to the three components of hook, rope, and brake. Once appear problem, the three components easily to hang fall, even cause serious casualty accidents.
Hook one thousand jins are common problems mainly rope decoupling, where objects when bundling is not good, one thousand jins of rope between the Angle of more than 120 degrees, or in the lifting hook side by touch, weight one thousand jins when the shelf at the bottom of the cord will be pulled out from the hook. In addition, because the hook is made of grey cast iron or cast steel material, its brittleness, don't touch resistance, easily broken, so, in the process of lifting objects, if the space is narrow small, or the operator operation carelessness, the pulley will be damaged due to collision. Once the wheel is damaged, the rim breach can cause of wire cutting, even to cut off the wire rope and cause an accident. If the operator is not in time to hook pulley, the pulley can be caused by rotation is not flexible and excess amount of wear at the bottom of the tank, the time, the pulleys will split half and hook will be issued in the operation accident. Not only that, when the amount of wear at the bottom of the tank increases, will make the steel wire rope embedded in deep, increase friction resistance, which can lead to wire embedding quantity, increase resistance, which can lead to accelerated scrap steel roughcast.
