Research on Main Shaft s Skip Weight-fixed Loading System of Coal Mine;

The new system implements automatic and weight-fixed loading.

The applications of weight-fixed loading system are introduced, in which some crucial problems during operation, such as gate unable to close, hoisting without loading, lack of the oil-level protection and coal conglutination in movement are improved.

Modeling and prediction for dynamic measurement of the skip weight-fixed loading system in vertical shaft

The characteristics of the working flexural moment of force and the needed least length of goods bearing surface for the flat car underframe using unsymmetrical lateral pedestal are studied, and the method of avoiding concentrated loading for goods with unsymmetrical pedestal is also discussed in this paper.
