This diploma thesis deals with the proposal of shock absorption of the boom of the skid steer loader Locust L 903. The aim of the diploma thesis is to design a shock absorption system for boom when driving the loader on uneven terrain. The first chapter of the presented work describes the mobile working machines among which belong to the front loaders are driven by wheel slipping. The second chapter describes hydraulic devices such as hydrogenerators, hydromotors and hydraulic accumulators. This chapter also includes the calculation of the hydraulic accumulator capacity required for our design. The third part of the diploma thesis describes the shock absorption system and its current overview. The next chapter describes the aims of the thesis. In the fifth chapter of the diploma thesis are indicated the materials and methods we used in our design of damping. The last part of the thesis deals with the evaluation of the measurements, the proposal of shock damping itself and the final evaluation of the results of the work.
