[0002] In the inclined shaft transportation system, due to cost reasons, monorail crane, ground rail transportation, overhead man-car and other transportation modes coexist in the same tunnel. According to the regulations, the ground rail transportation system must be equipped with a reliable runaway car protection device. However, the most important component of the runaway car protection device, the car barrier, can only meet the use of ground rail transportation. The monorail crane or overhead man-car installed on the top of the tunnel is blocked in position, affecting normal production operation;

Although the ground-lifting car barrier does not affect the operation of monorail cranes and overhead cranes in terms of location, it is not suitable for use in ground rail transportation and will bring new safety hazards. The National Center for Safety Standards does not recommend its use. Utility Model Content
