High quality service provider for mining equipment improvement
Mine hoist is key equipment for mine exploration. With the continuous improvement of mine exploration technology, the mine hoists are developing towards a large-sized and efficient direction. Due to large hosting load, high speed and complex working conditions, the demands toward brake system are growing higher as well. For the electrohydraulic safety brake system of constant torque controlled by secondary brake mode, the variation of brake deceleration is great under different working conditions and the brake process is unstable, therefore, during the safety brake process, the slipping of steel wire rope occurs frequently, and it reduces the safety performance and service life of equipment, so it is difficult to meet the requirements of equipment to safety brake. Electrohydraulic brake and control device with constant deceleration can well solve the problems existing in safety brake system of constant torque.
