The aim of this graduate thesis was the construction of a cargo platform with load capacity of 500 kg (5000 N) that will lift the equipment to be serviced from the ground level to the first floor. In the first part of the thesis, a short classification of platforms is shown according to their purpose, while the second part is based on the strength calculations and building of the platform itself. The construction is carried out using two trapezoidal spindles located in the supports. The lifting cab is constructed in the form of a welded structure whose load caryiing capability and strength are checked with the help of FEM analysis. The platform is robustly designed to minimize maintenance requirements and to ensure reliable operation without malfunctions. A safety assessment was also carried out and propper safety precautions were taken into consideration during construction. During construction of platform, 3D models of all embedded parts were made for testing purposes and for checking kinematics of all moving parts. The platform is calculated according to the given project parameters and the literature. Cad program packages MathCad and SolidWorks 2017 were used during making of this thesis.
