FUNCTIONAL DESCRIPTION

1 MECHANICAL CONSTRUCTION AND OPERATION

The equipment is attached to the column with steel cables and bearing brackets. The motor
placed in the upper end of the column moves the equipment up and down along the column.
Inside the column there is a counterweight which compensates the weight of the equipment.
The counterweight and the equipment are connected to each other with steel cables through
pulleys so that the movement of the counterweight is double related to the movement of the
equipment. Therefore the weight of the counterweight is only one half of the weight of the
equipment.
The equipment itself consists of the Z-carriage and the rotating unit. The upper horizontal part
of the Z-carriage (upper support arm assembly) supports the rotating unit and contains
mechanics determining the kinematics of the rotation movement. Low power supply with
mains filter is also placed in the upper support arm assembly.
The vertical assembly of the Z-carriage contains the guidance wheels and pulleys of support-
ing cables. Mains switch, fuses and Hall detectors for up/down movement are also located in
this assembly.
The lower horizontal assembly (lower shelf assembly) of the Z-carriage contains patient sup-
port mechanism, keyboard and keyboard processor.
The rotating unit consists of three main assemblies: rotating part, tube head assembly and
film cassette mechanism. The rotating part includes the rotating motor with gears, generator
processor and X-ray generator.
The remote control switch is connected to the equipment with a cable.
