Maintenance, Inspection and Test:
Joerns Healthcare recommend a thorough inspection and test of the Hoyer Mobile Hoist lifting accessories, slings etc. is
carried out at least every six months. The examination and test should be conducted according to the recommendations
and procedures below. Joerns Healthcare recommend maintenance, inspection and certified testing is carried out by
authorized service dealers only.
•
SPREADER BAR:
Check the spreader bar for freedom of rotation and swing. Check for wear on the central pivot.
Check for presence and condition of the wear washer. Check for firm attachment to the boom. Inspect for excessive
wear on the sling hooks and any side suspenders used in conjunction with the spreader bar. Check that the sling
retaining disks are fitted and function as intended. Lubricate the main suspension point and central pivot with a light
mineral based grease or silicon spray.
•
BOOM:
Check for secure attachment of the boom to the mast. Make sure there is only minimal side movement of the
boom and the boom is free to rotate on the boom bearing. Check the boom is centered and does not exhibit signs of
damage. Check that the actuator or hydraulic unit mounting on the boom is secure.
•
MAST:
Check the operation of the mast locking device. Make sure the mast fully engages into the socket. Check that
the bottom actuator or hydraulic unit mounting is secure.
• CONTROL BOX (Electric only):
Check the function of the emergency stop button. Inspect the hand control socket
for correct fitting. Check functioning of the hand control. Check the redundant controls and confirm they operate as
intended.
•
LEG ADJUSTMENT:
Check the leg linkages are secure. Operate the leg adjustment pedals or handset controls
(electric leg models only) to confirm smooth opening and closing of the legs. If leg linkages are damaged, they
should be replaced. Confirm the leg adjustment mechanism locks/ locates correctly in all open and closed positions.
MAINTENANCE:
Lubricate the leg adjustment mechanism with a light mineral based grease.
NOTE:
To ease application of the lubrication, the mast should be removed from the cross member and the grease
applied from inside the mast socket (foot pedal operation only).
•
LEG PIVOTS:
Check the leg pivots are secure and the legs pivot freely. Any stiffness must be investigated. Strip out
the leg pivots and lubricate with a light mineral based grease. Make sure there is no excessive play in the leg pivots.
•
CASTERS:
Check all casters for firm attachment to the legs. Check for free rotation of the caster and the wheels.
Remove any build up of threads, hair or fluff. Lubricate if necessary with a light mineral based grease or silicon
spray. Check correct operation of the brakes. Confirm all four casters sit firmly on the ground.
•
ACTUATORS (Electric models only):
The actuators should require no maintenance other than checking for correct
operation and listening for unusual noise. Ensure all fixing points are secure. Confirm the anti-crush mechanism is
operational (lifting actuator only). If in doubt, DO NOT use and have the unit checked by a qualified person or authorized
Hoyer Service Provider.
