Bucket elevators
Žák, Zdeněk ; Jonák, Martin (referee) ; Malášek, Jiří (advisor)
This bachelor thesis deals with the transport equipment using as the main transport element buckets. To specify this is a device type of elevator, conveyor, digger and excavator, including companies producing these devices. Further work is focused on theoretical and technical approach to calculate where the theoretical part of the thesis deals with the mathematical expression shape layers and logarithmic spiral and in the technical part calculations required to design and determine the parameters of devices. The last section is an overview of transported materials.

Design of excavator
Brza, Lukáš ; Zdařil, Zdeněk (referee) ; Křenek, Ladislav (advisor)
The design of the excavator follows requirements of machines for demolition work. The excavator is equipped with an innovative type of under carriage, which not only increases mobility over the demolition sites but also the visibility from the driver’s cabin. The components of the excavator, that improve the demolition work, are special types of tracks, suspensions and articulated steering. Tracks can change their shape to increase the stability and also to adapt to the diff erent types of ground. The suspensions with tracks are able to adapt to the terrain thereby they lighten the asperity. Suspension can also tilt or even raise the excavator and thereby increase the angle of visibility from the cabin. This function is necessary mainly when taking down higher constructions. Articulated steering is a new function that has never been used for excavators. This steering was chosen due to fl exible movement over demolition sites. The main aim of the project is to create a new design of the excavator, but more importantly to distinguish the excavator from the excavators already on the market, with regards to its esthetics and under carriage innovation.
