Hydraulic pullers

This diploma thesis deals with the design of the hydraulic puller. Furthermore, the diploma thesis presents the analysis of possible design solutions. It includes processing the selected design of the hydraulic puller with parameters: maximum pushing force 50 kN, speed of work movement 0,05 m.s-1. The analysis by using finite element method (FEM) is made. The next part of thesis includes the design of hydraulic circuit of puller. In the last part of thesis there is the design for replacement of hydraulic puller by mechanical systems
