This paper introduces the design of a loading ramp for the loading and unloading of tram mo-tor units onto transport trolleys. The structure”s design is part of a novel technology for the loading, unloading, and transportation of trams for standard track gauges, specifically de-signed for a track gauge of 1009 mm, in the repair facility known as ”Tramcar.” There exists a need to replace the current technology, which relies on sequentially partially lifting the motor units using an emergency crane. A unique aspect of the loading and unloading processes is the presence of a combined track with a shared rail, necessitating a 213 mm lateral shift of the load. The described structure is capable of moving the tram motor unit in the d direc-tion. Additionally, the loading ramp is a relocatable installation, allowing it to be positioned wherever there is a combined track and moved away after use to avoid obstructing transport or maneuvering operations. A significant advantage is that it does not the deactivation of the contact wire during operation. The ramp is composed of several modules: a horizontal sec-tion with two parts and a trestle with four parts. The manipulation of the motor unit is facilitat-ed in the horizontal section, which s curves in both of its modules. The paper presents the design and strength calculations using the finite element method.
