1塔机起重力矩限制器现状分析在80年代末,塔机领域的科技工作者创造出了电脑自动控制的起重力矩限制器,极好地实现了图1所示的起重性能。可是,建筑施工环境粉尘太多,常常造成系统无法工作,再加上价格昂贵和维护困难,该系统逐渐退出市场。90年代,科技工作者们又创造出了弓形起重力矩限制器,较好地实现了图2所示的起重性能,且弓形起重力矩限制器以它简单、实用、成本低被广泛采用。但是,在实际使用中,经常出
1 Tower crane lifting torque limiter status analysis In the late 1980s, tower crane technology workers to create a computer automatically controlled lifting torque limiter, excellent to achieve the lifting performance shown in Figure 1. However, too much dust in the construction environment often causes the system to become inoperable. In addition, the system is gradually withdrawn from the market due to its high cost and maintenance difficulties. In the 1990s, scientists and technicians also created a bow-type moment of inertia limiter to better achieve the lifting performance shown in Figure 2, and the bow-shaped moment of inertia limiter with its simple, practical and low cost is widely used . However, in actual use, often out
