实践证明，虽然保护和监护系统不断完善，提升容器的过卷事故仍时有发生，由于提升运行速度大，只靠紧急制动是不可能制动住过卷的提升机容器。因此，为了在有限的距离内使过卷的提升容器停止，以减少过卷事故造成的损失，研制性能优良的缓冲器是非常必要的。目前，我国除了采
Practice has proved that although the protection and monitoring system continues to improve, improve the container overvoltage accidents still occur, due to enhance the speed, only by emergency braking is impossible to brake over hoisting hoist container. Therefore, in order to stop the over-hoisting container within a limited distance and reduce the loss caused by the over-rolling accident, it is necessary to develop a good-quality buffer. At present, except for mining in our country
