Connecting the Handset to the Hoist
A sturdy ladder or steps may be required in order to access the underside of the Hoist to attach the hand controller.
Caution should be used when this is required.
Should the grey rubber airline that connects the handset to the Hoist become disengaged from the underside of the Hoist it
must be re-connected in order for the Hoist to work.
The rubber airline may become disconnected for the following reasons:
1.
The Hoist is pulled along the track by the handset.
2.
The tubing accidentally gets wrapped around an object while a Hoist or transfer is being performed.
3.
It is accidentally pulled out by the Hoist operator or the individual being hoisted.
In this section the correct procedure on attaching the Handset will be determined.
The Pneumatic Handset is attached to the Hoist through the Airline Grommet on the underside of the Hoist as shown in Figure
19. While holding the Airline Connector at the end of the Handset Air Tubes, locate the two small metal ribbed pins with the
Airline Grommet on the Hoist. To correctly locate, ensure the profile of the two parts are lining up, this means the grey rib
profile, which faces inwards on the Hoist aligns with the grey rib on the Handset, this is the only way the Handset can be
connected, therefore it is not possible to incorrectly mate the two parts.
Once the two parts have been aligned, ensure that the Handset is pushed into the Grommet properly, with both metal pins
being fully inserted into the Grommet. This is important to ensure there is no air leak which will affect the Hoist functionality.
The images below refer to a Powered Traverse Hoist Handset, the same process applies to the Manual Traverse and Powered
Traverse Powered Auxiliary Hoist Handsets.
Perform a brief test to ensure proper connectivity. If the Hoist is OFF, turn it ON. Use the handset to RAISE and LOWER the carry
bar. For powered traverse Hoists, also check the Hoist correctly moves FORWARD and BACK along the track using the handset.
See section ‘Hoist Operation’ for details of how to perform these functions. If these operations all work as intended, then the
handset is correctly connected to the Hoist.
If the Hoist does not work properly, check to ensure that the grey ribs on the grey
rubber grommet on the underside of the Hoist and the airline tubing are lined up
properly.
If they are not lined up properly, then remove the airline, line up the grey lines and
then re-insert it into the rubber grommet. Perform the brief test as described
previously. If there are still problems with the Hoist, then contact your local
Mackworth authorised dealer for service.
To remove the handset, follow the procedure above in reverse.
