1. The influence of the characteristics of the load, the peculiarities of operating cycles of lift-load truck and its general characteristics and also factors on operating efficiency of lift-load truck have been investigated .
2. The mathematical model of work and movement has been carried out, which allows the analysis of the influence on the operating efficiency of lift-load trucks in longitudinal direction of such factors as: the weight and its position, the rational diagram of the operating cycle of lift-load truck and the shoulder of transport load, the dynamics of movement and processing of load, conditions of movement.
3. The procedure of the development of the system of non-linear integral and differential equations of mathematical model has been created.
4. The three-staged testing procedure of mathematical model has been suggested.
5. New results of calculations have been taken by means of the model.
6. The applied program’s kit has been worked out that besides fourteenth initial parameters forty-two constructive parameters together with the characteristics of transmission (six) and profile of road (two) which has allowed the automation of the investigation .
7. Recommendations on improving of operating efficiency of lift-load truck made based on the results of the investigation.
8. Means of increasing the operating efficiency of lift-load trucks and the set of constructive designs developed in the lift-load truck with experimental fork lift have been suggested.
9. A new technological process of load handling has been carried out.
10. New models of lift-load trucks testing procedure that are provided into the production.
11. Including into the working cycle the operation of alignment and its overlap with operation of transportation would allow the improvement of the efficiency of lift-load truck usage.
12. To improve the work productivity of lift-load truck the experimental fork lifter has been carried out.
13. The developed testing procedure has allowed the investigation of new constructive design’s influence on the operating efficiency of lift-load trucks.
14. The created complex of measuring equipment has been evaluated positively at testing due to computers.
15. The worked out fork lifter has been suggested and taken for production .
16. The design of fork lifter allows the overlap of working cycle that improves the productivity of lift-load truck.
Technical design used in the lift-load truck with experimental fork lifter with side fork shifter can be the basis for creation of complex system of handling load processing and transmission work and creation of conception model of lift-load truck.
