“电动环链葫芦”又称环链电动葫芦是一种轻小型起重设备。电动环链葫芦由电动机，传动机构和链轮组成。电动环链葫芦全部按照国际标准生产，机身外形美观，结实耐用，内部齿轮全部经过高温淬火，增加了齿轮的耐磨性和韧性，采用国际最先进的工艺，做工精细，齿轮间契合严密。电动环链葫芦结构特点：电动葫芦产品结构，机体选用高强度拉伸壳体或压铸铝壳体，采用薄壁挤压成型工艺精密制造，体积小、重量轻、强度高。标准的电动环链葫芦具备独立的变速箱系统，密封变速箱内的二级同轴传动齿轮机构，采用长寿命的油浴润滑系统。电动环链葫芦粉末冶金离合器作超载保护装置，制动采用盘式直流电磁场制动，制动力矩大、平稳、迅速、噪音小 。 "Electric chain hoist is also called the" chain electric hoist is a small-sized lifting equipment. Electric chain hoist motor, drive mechanism and the sprocket. All electric chain hoist according to international standard production, fuselage, beautiful shape, solid and durable, internal gear all after high temperature quenching, increase the gear abrasion resistance and toughness, USES the international most advanced technology, fine workmanship, tight fit between gear. Structure characteristics of electric chain hoist, electric hoist product structure, the body, choose high strength tensile shell or die casting aluminum shell with thin wall extrusion forming process of precision manufacturing, small volume, light weight, high strength. Standard electric chain hoist with independent transmission system, sealing secondary coaxial transmission gear transmission mechanism, the long life of the oil bath lubrication system. Electric chain hoist powder metallurgy clutch overload protection device, brake the brake disc dc magnetic field, the braking torque, smooth, fast, low noise. 电动环链葫芦维护方法: Electric chain hoist maintenance methods: 1.新安装或经拆检后安装的电动葫芦，首先应进行空车试运转数次。但在未安装完毕前，切忌通电试转。 1. The new installation or after overhaul of electric hoist, first of all should be empty test run several times. But in before installation, power of avoid by all means try to turn. 2.电动环链葫芦在正常使用前应进行以额定负荷的125%,起升离地面约100毫米，10分钟的静负荷试验，并检查是否正常。 2. Should be done before the electric chain hoist in normal use to 125% of the rated load, lifting off the ground is about 100 mm, 10 minutes of static load test, and check whether the normal. 3.动负荷试验是以额定负荷重量，作反复升降与左右移动试验，试验后检查其机械传动部分，电器部分和连接部分 是否正常可靠。 3. The dynamic load test on the rated load weight, for lifting and moving test repeatedly, after test to check the mechanical transmission parts, electrical parts and the connection is normal and reliable. 4.在使用中，绝对禁止在不允许的环境下，及超过额定负荷和每小时额定合闸次数(120次)的情况下使用。 4. In use, absolutely forbidden in not allowed, environment, and more than the rated load and rated closing times per hour (120) under the condition of use. 5.安装调试和维护时，必须严格检查限位装置是否灵活可靠，当吊钩升至上极限位置时，吊钩外壳到卷筒外壳之距离必须大于50mm(10t,16t,20t必须大于120mm)。当吊钩降至下极限位置时，应保证卷筒上钢丝绳安全圈，有效安全圈必须在2圈以上。 5. Installation and maintenance, must strictly check whether the spacing device is flexible and reliable, when the hook rose to the limit position, hook enclosure to the drum shell of distance must be greater than 50 mm (10 t, 16 t, 20 t must be greater than 120 mm). When the hook fell to the limit position, should ensure the safety of steel wire rope on the drum circle, effective safety strap (must be at least 2 laps. 6. 不允许同时按下两个使电动环链葫芦按相反方向运动的手电门按钮。 6. Do not allow the press at the same time two electric chain hoist pushing in the opposite direction of movement of the flashlight door button. 7. 工作完毕后必须把电源的总闸拉开，切断电源。 7. After the completion of the work must be total power brake away, cut off power supply. 8.电动环链葫芦应由专人操纵，操纵者应充分掌握安全操作规程，严禁歪拉斜吊。 8. Electric chain hoist should by specialist manipulation, the operator should fully grasp the safety operating rules, it is forbidden to slanting inclined condole. 9.在使用中必须由专门人员定期对电动环链葫芦进行检查，发现故障及时采取措施，并仔细加以记录。 9. Must be in use by specialized personnel regularly check the electric chain hoist, found fault take timely measures, and carefully record. 10.调整电动环链葫芦制动下滑量时，应保证额定载荷下，制动下滑量S≤V/100(V为负载下一分钟内稳定起升的距离)。 10. Adjust the electric chain hoist brake declines, shall ensure that under rated load, brake in S V / 100 or less (V for stable hoisting loads a minute distance).
