Joerns Hoyer Presence
Joerns · Model Hoyer Presence
Lightweight aluminum construction Smart monitor technology Swan neck style legs Low leg option kit.
Key tips
- ·Mounting and securement hardware takes real fatigue from vibration and road shock - inspect it as carefully as the device itself.
- ·Post-call battery and function checks catch transport-induced faults that a scheduled PM would miss for months.
Typical Failure Modes
Compiled for this model from its own documentation and established engineering knowledge for this equipment class - not from a verified service record. Confirm against the manufacturer's service manual.
Hand control not responding / no powered movement
HighSymptoms: Lift / lower or traverse does not respond to the hand control.
Root cause: Discharged or mis-inserted battery, an active emergency stop, an obstruction or overload, or a faulty hand control / cable.
Lift actuator / strap / mast fault
MediumSymptoms: Will not raise or lower, runs one direction only, noisy or slow, strap frays.
Root cause: Worn lift actuator / motor, or a frayed / twisted lifting strap or chain.
Battery will not hold charge
MediumSymptoms: Short run time, frequent low-battery, unit dies mid-transfer.
Root cause: Aged battery pack or a charger / charging-contact fault.
Traverse / rail-carriage fault (ceiling)
MediumSymptoms: Carriage will not move along the rail, or binds.
Root cause: Worn carriage wheels, a rail obstruction, or the traverse motor.
Overload / slack-strap / emergency-lowering fault
HighSymptoms: Lift stops with an overload indication, slack-strap cut-off active, or emergency lowering does not work.
Root cause: Load over the rated limit, the slack-strap sensor, or the emergency-lowering mechanism.

PM Checklist
Preventive-maintenance tasks typical of this equipment class. Perform to the manufacturer's procedure and your facility's policy - this is general reference, not a schedule for this specific unit.
- ·Post-call function and battery check
- ·Mounting / securement inspection
- ·Annual full PM and vibration-tolerance check
Troubleshooting Approach
A starting sequence for this model, compiled from its documentation and engineering knowledge for this equipment class. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Hand control does not respond / no powered movement
- Confirm a charged, correctly inserted battery.
- Clear any obstruction and check the load is within the rated limit.
- Confirm the emergency stop button is not pushed in.
- Reseat the hand-control plug; try the up / down buttons on the control box if fitted.
- If the control-box buttons work, replace the hand control; if not, use the emergency lowering and refer the actuator / control box.
Symptom: Will not raise or lower / strap or actuator fault
- Check the strap / chain is not twisted, frayed or fouled at the drum - retire a frayed strap immediately.
- Listen for the lift actuator / motor under command.
- Confirm the slack-strap cut-off is not active (keep the strap under tension).
- Check the actuator supply at the control box.
- Replace the actuator / motor and load-test to the rated limit.
Symptom: Battery will not hold charge / dies mid-transfer
- Charge fully and check the charger / charging contacts.
- Run a battery test if the lift supports one.
- Replace the battery pack.
- Confirm several full lift cycles on a charge.
- Inspect the charge connector on the control box.
Symptom: Ceiling-lift carriage will not traverse / binds
- Check the rail for debris, a joint step or an end stop.
- Inspect the carriage wheels for wear or flat spots.
- Confirm the traverse motor runs (powered traverse).
- Lubricate the rail only per the manufacturer (many are dry-running).
- Replace the carriage wheel set.

Safety & Recalls
Synced live from the FDA openFDA API.
- RECALL
Unapproved Design Change (by base supplier) consisting of a reduction in the number of mast-to-base welds (from four welds to two welds).
- RECALL
A field correction is being conducted on select models of Hoyer Patient Lifts because of hydraulic jack problems that have resulted in patient injury. The possibility exists that the mounting stud located in the bottom of the hydraulic jack could become loose allowing the jack to disengage from the mast of the lift.
