额定负载转矩
The writer verifies that the designed safety coefficient of wire line should be bigger than 3 while the hook has the speed of 0.4-0.55 m/ sec at hook load rating, corresponding to the drawworks operation at the third speed and air clutch operation at rated torque;
证实额定大钩钩载时,大钩速度为0.4~0.55米/秒,相当于绞车在Ⅲ档工作,气胎离合器在额定扭矩工作,此时钢丝绳设计安全系数大于3。
