The aim of the paper: rise of technical level hoisting-transporting and transporting techniques by the way of development machines construction and it using regime. Methods of search: theoretical research mathematical models with use of mathematical packet Maple, table processor Excel and others, experimental research on laboratory equipment with use train measurement apparatus. Theoretical and practical results: 1. The technique of restoration of working capacity of brake pulleys-semimuffs of tape conveyors is developed by a method of a powder dusting. 2. The physical model of a career dredge which has allowed to simulate processes shearing a ground and arising dynamic loadings in elements of executive mechanisms of a dredge is developed, designed and made. 3. The experimental model of a caterpillar drive of a dredge is developed. 4. The multimass mathematical model of the mechanism of lifting of loads of the crane of the bridge type, considering mutual influence of elements of the mechanism on factor of dynamism of the bridge is developed. 5. The kinematic law of movement of the crane on conic wheels on a rail way is established. 6. The mathematical model of an operating mode of cranes and loading cranes of bridge type is developed at dynamic influence of a wind. 7. Research of work of load-lifting cranes with replaceable load handling adaptations is conducted and the estimation of their influence on an operation deadline is executed. 8. Methodology bases on perfection of methods of an estimation of a residual resource of cranes for the purpose of their simplification and possibility of their performance at engineering level are developed. 9. The behavior of an aeromix in the pneumotransport pipeline is investigated at a rotary mode of movement. 10. Researches of power and kinematic factors in four-basic walking locomotor a dredge are conducted. Innovations: 1. The model of process of restoration of working capacity of brake pulleys-semimuffs is developed by a method of a powder dusting. 2. The imitating model processes of cutting of a ground taking into account dynamic loadings in elements of executive mechanisms of a dredge is developed. 3. The generalized multimass mathematical model of the mechanism of lifting of loads of the crane of the bridge type, considering mutual influence of elements on dynamism factor is developed. 4. The kinematic law of movement of the crane on conic wheels on a rail way is established. 5. The mathematical model of an operating mode of cranes and loading cranes of bridge type taking into account dynamic influence of a wind is developed. 6. Research of work of load-lifting cranes with replaceable load handling adaptations is conducted and the estimation of their influence on an operation deadline is executed. 7. Bases of methodology of an estimation of a residual resource of cranes with possibility of their performance at engineering level are developed. 8. Modeling of behavior of an aeromix in the pneumotransport pipeline is spent at a rotary mode of movement. 9. The model four-basic walking locomotor a dredge taking into account power and kinematic factors is developed. Efficiency of innovation: on the basis of methods of mathematical modeling perfection of indicators of a technological level of hoisting-and-transport and digging cars at their designing and modernization. Area of application: Mechanical engineering.
