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 supporting
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 support
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 proces-
sor and x-ray generator. The tube head assembly contains the collimator / primary slot mecha-
nism, and the cassette mechanism contains the secondary slot.
The remote control switch is connected to the equipment with a cable.
