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。但未安装完毕前，切忌通电试转。 1., the newly installed or disassembled and installed electric hoist, first of all, empty cars should be tested for several times. But before the installation is completed, do not turn on the electricity. 2.正常使用前应进行以额定负荷125%,起升离地面约100毫米，10分钟的静负荷试验，检查是否正常。 2. before normal operation, we should carry out static load test with a rated load of 125%, lifting about 100 millimeters, and 10 minutes away from the ground to check whether it is 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。 The 3. load test is the test of repeated lifting and left and right movement with the weight of the rated load. After the test, the mechanical transmission part, the electrical part and the connecting part are checked properly. 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)情况下使用。 4., in use, it is strictly prohibited to use in the environment which is not allowed, and exceed the rated load and the rated closing times per hour (120 times). 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, debugging and maintenance, it is necessary to strictly check the flexibility of the limit device. When the hook rises to the top of the limit position, the distance between the hook shell and the drum shell must be greater than 50mm (10t, 16t, 20t must be greater than 120mm). When the hook is lowered to the lower limit, the wire rope safety circle on the drum should be ensured, and the effective safety circle must be in the 2 circle. 6.不允许同时按下两个使电动葫芦按相反方向运动的手电门按钮。 6. is not allowed while pressing the two electric hoist movement in the opposite direction of the switch button. 7.工作完毕后必须把电源的总闸拉开，切断电源。 7., after the work is completed, the power gate must be opened and the power will be cut off. 8.电动葫芦应由专人操纵，操纵者应充分掌握安全操作规程，严禁歪拉斜吊。 8., electric hoist should be operated by special persons. Operators should fully grasp the safety operation rules and strictly prohibit oblique pulling. 9.在使用中必须由专门人员定期对电动葫芦进行检查，发现故障及时采取措施，并仔细加以记录。 9., during the use, regular personnel should check the electric hoist regularly, find out the faults, take timely measures and record them carefully.
