Maintenance should be completed by an approved service engineer every 6 months to ensure the product’s required standard is maintained. The service history of the product should be documented each service. This is documented in the service log, found in the back pages of the user manual.
When recording the service in the service log, ensure that the serial number of the portable lift and user manual align. Each portable lift is provided with its own user manual.
The below sub-sections provide detailed instructions on what must be inspected/tested for each component on the portable lift for every service. Follow the guidelines below for a successful portable lift service.
4.1 Covers
• Visual inspection of the cover integrity, including cracks, burns or any impact damage.
• Ensure that the covers are fitted correctly, check that the screws are tight.
• Inspect the label integrity, and ensure that they are legible and aren’t peeling of the covers
• Ensure the serial number is legible.
4.2 Carry Bar
• Inspect the carry bar for damage such as deformation, cracks, and large dents which may affect the function and safety of the component.
• Ensure that the carry bar spring clips remain functional.
• Check that the carry bar hooks and springs remain smooth, as sharp edges may cause damage to the slings.
• Ensure that the carry bar is fitted to the QRS Hook properly. See the user manual for correct attachment.
4.3 Handset
• Inspect and test handset buttons are all functional.
• Ensure handset labels remain legible.
• Ensure the handset is connected to the portable lift correctly
4.4 Batteries
• Ensure that the battery leads are attached properly between the battery terminals and the PCB
• General examination of batteries for burns at terminals and cuts/exposed wiring along the leads.
• Perform a battery test to determine the condition of the batteries.
4.5 Trolley/Wheels
Examine the wheels for damage such as cracking and general wear
• Ensure that the wheels are running smoothly in the track (track may have debris inside)
• Ensure that the portable lift traverses with the handset command smoothly. (powered traverse portable lifts
only)
• Ensure that the Trolley system functions and that the portable lift is positioned on the trolley hooks and is secure.
4.6 Toggle Switch and Pull Cord
• Ensure that the two-phase switch is fully operational.
• The portable lift should operate as normal when the switch is pushed into the up position.
• Power to the portable lift should be removed when the toggle switch is in its down position.
• Inspect the condition of the pull cord, and ensure that the cord has not been modified (cut to length)
• Ensure that the pull cord label remains legible.
4.7 Lift Motor
• Visual inspection of the component for any abnormalities.
• Inspect the motor gear shaft for wear. Excess wear should be cleaned and an inspection on the gearing condition should be done afterward. If the gear shaft is badly worn it must be replaced.
• Ensure that the motor gear shaft is meshing correctly with the hub.
• Re-grease the motor gear shafts.
• Perform a lift/lower test to ensure the lift motor is functioning correctly, this should be done with and without load. Ensure to listen for any unusual sounds and rattling coming from the motor.
4.8 Lift Tape Hub (Spool)
• Inspect the hub teeth for wear. Excess wear should be cleaned and an inspection on the gearing condition should be done after. If the hub is badly warn it must be replaced.
• Ensure that the hub teeth are meshing correctly with the lift motor gear shaft.
• Re-grease the hub.
• Test the function of the over-speed cam. Ensure that it returns to position after displacement.
4.9 Lift Tape
• Inspect the full length of the lift tape for any fraying or damage to the materials integrity.
• Ensure that the stitching remains in good condition, there should be no sign of any loose threads or fraying by the bindings, this should be checked at both ends of the lift tape.
• Ensure that the lift tape label remains legible.
4.10 Limit Switches
• Ensure that the limit switches remain functional.
• Test the bottom limit switch activates by fully lowering the lift tape out of the hub during normal use.
• Test that the bottom limit switch activates when the carry bar is removed from the portable lift.
• Test the upper limit switch activates by raising the lift tape all the way up to the top limit.
• Inspect the limit switch wires and solder points for any damage and exposed wire. Make sure to check inside the chassis as the cable runs inside.
4.11 PCB (Printed Circuit Board)
• Inspect the PCB for any damage such as cracks and electrical burns.
• Ensure that all the relevant components are plugged into the board correctly.
• Inspect the wiring for each component that plugs into the PCB. Ensure there are no exposed wiring.
4.12 LED Indicator (Membrane)
• Ensure that the buttons remain functional on the membrane.
• Test LED is functioning correctly, ensure that the LED is indicating the correct light for each scenario (where applicable)
4.13 Charging
• Inspect the condition of the charging unit, and ensure that the casing remains intact and there are no cuts or exposed wires.
• Inspect the condition of the charging dock (handset case), and ensure that the jack plug remains fixed into the case and the handset docks correctly into the plug.
4.14 Fixings
• Inspect all the main nuts, bolts, screws, and other fixings are secure and tight, if any fixings are loose ensure to tighten accordingly.
4.15 Ceiling Track
• Ensure that the track profile matches the profile of the portable lift trolley.
• Inspect the integrity of the track system. Ensure that the track is not damaged and/or deformed.
• Inspect the condition of the track brackets, ensure that the brackets and track are secured in place with the track wedges. The track wedges should be locked in place with the M3 screws on either side.
• Ensure that the alignment between two track sections align, and that there is no gap between two aligning tracks. Test the traversing of the portable lift between the track sections is smooth and allows transfer.
• Ensure that the end stops, safety bolt and end caps are all secured correctly to the track system.
• Clear out the internal of the track profile from any debris.
4.16 Slings
• Inspect the sling for cuts, frays, tears, and burns along the full profile of the sling and straps.
• Inspect the sling stitching for any tears, stretching, and loose threads along the full profile of the sling and straps.
• Ensure that the label remains secure and legible.
If there is a problem discovered with the sling, it should be noted on the service sheet and be brought to the attention of the person(s) who requested the service to be carried out. In addition, notify the customer on-site or the manager if it is a care facility. The serial number, type of sling, and condition should be noted on the service sheet. Mark the date of inspection on the sling service label.
