摘要:
A rotary part of a crane is associated with an electric slewing mechanism including at least one geared electric motor unit of which the electric motor is powered in such a way as to produce a slewing torque having a certain maximum value. When the crane is in use and for conditions such as windspeed greater than a given value, jib length greater than a given value and moment of the lifted load greater than a given value, the maximum value of a slewing torque produced by the electric motor is increased. The crane thus becomes easier to drive, particularly in the phases during which the jib is adopting a “windward trend”.
摘要(中):
起重机的旋转部分与电动回转机构相关联,该电动回转机构包括至少一个齿轮电动机单元,电动机以这种方式供电以产生具有一定最大值的回转转矩。 当起重机在使用中,并且对于诸如风速大于给定值的条件,大于给定值的起重臂长度和提升载荷的力矩大于给定值时,电动机产生的回转转矩的最大值为 增加。 因此,起重机变得更容易驾驶,特别是在起重臂采用“迎风趋势”的阶段。
