一、10吨起重机吊运10吨重物时发现第一档很慢或不动,这种现象对不对?第二档也不动对不对?答:第一档速度很慢是正常的,因为第一档起动力矩为70%Me以下(Me——额定转矩),第二档还不动是不对的,因第二档起动力矩为120～150%Me。此时应停车查明原因,不应再往第三档操作。二、开动大车或小车逐级加速操作的快慢程度怎样算?一般是否允许经常打反车制动?必须打反车
First, the 10-ton crane lifting 10 tons of heavy load found that the first file is very slow or not moving, this phenomenon is wrong? The second gear is not correct? A: The first gear is very slow, because The first gear starting torque is less than 70% Me (Me - rated torque), the second gear is not moving is wrong, because the second gear starting torque of 120 ~ 150% Me. At this point should stop to identify the reasons, should not go to the third gear operation. Second, start the cart or car step by step to speed up the operation of how speed? Generally allow regular anti-train braking? Must fight anti-car
