       荆棘、坎坷是磨砺开拓者意志的摇复;困难艰险,是开拓者前进路上的垫脚石。驾驭命运的舵是奋斗。不抱有一丝幻想,不放弃一点机会,不停止一日努力。
       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.
       起重机配件是机械工程中的重要工作部件,工程起重机三大配件构件常见问题:起重机作业时,操作人员要认真检查制动器的零部件是否运转正常,是否卡塞,闸瓦间隙是否合适,制动伦表面是否良好,调整螺母是否紧固。对于制动器的润滑每周应进行二次,但注意不要将润滑油沾在摩擦部件上。若闸瓦、制动轮、小轴、心轴等处磨损量超标;主弹簧、辅助弹簧出现断裂或塑性变形;制动等处出现裂纹;制动电磁铁、电力液压堆杆等出现故障时,因及时修理,不得带病运行,确保安全。起重机的三大构件是指吊钩、钢丝绳与制动器。这三大构件一旦出现问题,极易造成吊物坠落,甚至造成严重的伤亡事故。
       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.
    吊钩常见的问题主要是千斤绳脱钩,也就是当物体捆绑不好,千斤绳间的夹角超过120度,或吊运中钩侧向被碰,重物底部受搁时千斤绳会从钩中拽出。另外,由于吊钩系用灰铸铁或铸钢件材料制造,其脆性大,不耐碰,易破裂,因此,在吊物过程中,如果场地窄小或者操作者操作时大意,滑轮会因碰撞而受损。一旦滑轮受损,其轮缘破口会造成对钢丝绳的切割,甚至切断钢丝绳而引发事故。如果操作者未及时给吊钩滑轮加油,滑轮可因转动不灵活而导致槽底磨损量超标,久之,滑轮会半裂开来,吊钩就会在运行中发行事故。不仅如此,当槽底磨损量增大时,会使得钢丝绳嵌入量国中深,增大磨擦阻力,从而导致钢丝绳嵌入量加深,增大阻力,从而导致钢丝拉毛而加速报废。
       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.
