Courses

The goal of this course is to increase the expertise of VCU’s technicians and the fleet’s operators to a sufficiently high level in the field of Hydraulics. Following successful completion, the trainees will be expected to be able to perform the most common maintenance and repair activities with confidence, be able to read schematics and localize and resolve common  malfunctions. This course has been designed in such a way as to focus a lot of attention on the operation of various components, as well as on learning to recognise symbols and read schematics. The hydraulic system of the UK 112 has been adopted as an example. Hydraulics is applied physics and based on natural laws, which is why making calculations will also be attended to during the course. The course has been compiled by C. Poot.
