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.
