Casters and brakes
Casters and brakes description
The Vivid E80/E90/E95 has four casters (wheels), two Front
Casters and two Rear Casters.
• All Casters are mounted on swivels so they can change
direction as needed.
• The Front Casters can be locked in fixed directions.
• Three plastic pedals, used for controlling the brakes and
direction locks, are located at the front of the Ultrasound
system.
• The pedals are mounted on the Pedal Mechanism.
The Pedal Mechanism has these functions:
• direction lock
• parking brake
• release the two other functions, if activated
The direction lock and brakes are operating on the front
wheels. A lever placed on each of the front wheels give the
interface to the pedal mechanism. These levers are
engaged by rods being moved by a rotating bracket
(Bracket Rotation). When the mechanism is engaged in
either position, the pedal will not move back into a neutral
position. This is to indicate which function that is activated. It
will then be needed to release this by the release pedal.
• The Rear Casters have brakes that are operated individually
for each caster.
