Drive reconstruction of turning crane trolley
Banaś, Jiří ; Dzimko, Marián (referee) ; Brandejs, Jan (advisor)
The diploma thesis include improvement proposal of drive slewing 12,5t grabbing crane. Second part this work deal with causes which in the past lead to failure the supporting pole of grab crane by using FEM analysis. Detected causes are applied to new supporting pole of grabbing crane and comparison both results. In the last part of the thesis is constructional, technological and economical summary.

Material Handling Platform
Bíza, Pavel ; Kašpárek, Jaroslav (referee) ; Škopán, Miroslav (advisor)
The main subject of this thesis is the construction design of material handling platform with hydraulic drive with a loading capacity of 2 500 kg and lifting capacity of 1 800 mm. First of all, the thesis contains the selection of a suitable variant of lifting mechanism, static analysis and determination of the maximum load of the mechanism. The next section includes strength calculations of particular elements of the mechanism with regard to selected dimensions and loading. In the end, the calculation of the hydraulic drive and design of a hydraulic circuit for this drive are presented. The final output of the thesis is a drawing of the assembly of the platform.

The engine unit of a loader
Koksa, David ; Škopán, Miroslav (referee) ; Kašpárek, Jaroslav (advisor)
The work is focused on loading construction machinery and their engine units. The theoretical background research introduces the domain of wheeled loaders. Subsequently, three specific machines, which are available on the market, are selected from a similar model range. They are selected according to the specified technical criteria. Individual power requirements for various modes of operation are calculated according to a suitable algorithm. These power requirements are summed up to obtain the needed total power. Based on the calculated value of the total power the suitable engines from various producers are proposed at the end of this work. This was the goal of the work.
