DHP环链电动葫芦做工精细，结实耐用，是建筑等行业中不可缺少的起重设备。我们在使用DHP环链电动葫芦前，应做操作测试来检验DHP环链电动葫芦，保证我们以后的工作能够顺利的完成。那么，由骏腾起重为您讲解DHP环链电动葫芦在使用前应做的检验有哪些： 　　一、确实的按下按扭开关“下”的按钮，操作DHP环链电动葫芦下降，直到极限开关为止，此时电机会自动停止，确实的按下按扭开关“上”的按钮，直到链条完全收回到链条袋内，且电机停止运转。 　　二、检查DHP环链电动葫芦起重链的润滑情况，起重链条在出厂前就已经润滑上油，但在运送过程中可能会干掉，任何现成的润滑油都可以用来润滑起重链条，建议您在链条袋内维持少量的润滑油，让链条可以浸在润滑油内。 　　三、当主机的链条吊数为双链式或多链式时，严禁将下吊钩从链条中翻转，避免危险发生。 　　四、检查DHP环链电动葫芦链条目的方向性，所有的焊接点都应该在同一方向，惟有在所有的链条焊接点都在同一条线上时，才能完全正确定的操作。 DHP were studied.the optimum processing chain electric hoist fine workmanship, sturdy and durable, is indispensable to building industry such as lifting equipment. Before us in the use of DHP were studied.the optimum processing chain electric hoist, should do operation test to verify DHP were studied.the optimum processing chain electric hoist, ensure that our later work successfully completed. By jun teng lifting explain DHP were studied.the optimum processing for you, then, link chain electric hoist what inspection should be done before use: a, is press the button "down" button switch, operating DHP were studied.the optimum processing chain electric hoist down, until the limit switch, electric opportunity automatically stop right now, is press the button switch "on" button, until completely back to chain bag chain, and the motor to stop running. 2, check the DHP were studied.the optimum processing lubrication situation of chain electric hoist lifting chain, lifting chain have been oiling before they go out, but in the process of transporting might kill, any ready-made lubricating oil can be used for lubrication lifting chain, it is recommended that you maintain a small amount of lubricating oil in the chain bag, can let the chain in lubricating oil. Number three, when the host chain crane is dual chain or chain, the more it is strictly prohibited under the hook from the chain in reverse, to avoid danger happening. Four, check the DHP were studied.the optimum processing chain electric hoist chain goal orientation, all the welding point should be in the same direction, but in all of the chain when the welding points are on the same line, is to completely determine the operation.
