Operation (continued…)
11.5 Leg Adjustment:
The legs of the A205 hoist are electrically adjustable for opening, and
closing base width. The legs can be opened to enable access around
arm chairs or wheel chairs. For transferring through narrow
doorways, and passages the hoist legs should be in closed position.
Leg adjustment is achieved by pressing appropriate buttons on the
hand control. The legs’ motion will be stopped whenever the hand
control button is released.
11.6 Raising and Lowering the Boom:
The up and down movement of boom on A205 hoist is achieved by
a powerful electric actuator which is controlled by hand control.
The hand control has two button with directional arrows UP and
DOWN. The actuator stops automatically at the limit of travel in
both directions.
11.7 Castors and Braking:
The A205 hoist has two rear castors with brake. The rear castors
can be braked for rotation, lateral movement, and parking. To
apply the brake, press the brake pedal down with your foot. To
release the brake, press the raised pedal towards the wheel.
During the lifting, the rear wheels should remain unlocked so that
the hoist will move to the patient’s centre of gravity. The wheels
should, however, be locked if there is a risk of hoist moving to the
patient. For example, when lifting the patient from the floor.
Locked wheels during lifting will increases the risk of the hoist tilting
over. When the hoist is not in use, stored away, ensure the emergency
stop is depressed to prevent any unintended use by minors playing
around the device
User Note
The control boxes utilised within the devices use internal relay switches for
actuator operation.
Pressing a hand controller button energises this control box relay with a small
magnetic field, causing it to close. Releasing the hand controller button de-
energises the control box relay, causing it to open.
Immediately “re-pressing” the relevant control button before the relay’s
magnetic field has had time to reset will result in no additional activation.
This is not a fault of the system and no damage is caused by this process.
If this situation occurs, please release the control button for two seconds and
then press again. By this time the magnetic field will have dissipated and the
operation of the button will re-energise the switch enabling further use
.
