11. Maintenance, Inspection and Test
Joerns Healthcare recommend a thorough inspection and maximum safe working load test of the
Oxford Dipper and lifting accessories, slings etc. is carried out 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 authorised
service dealers only.
NOTE
: These recommendations are in compliance with the requirements of 1998 No 2307
Health and Safety: The Lifting Operations and Lifting Equipment Regulations 1998.
This is a UK regulation. Outside the UK please check your local requirements.
• SPREADER BAR:
Check the spreader bar for freedom of rotation. Check for firm attachment
to the boom and the operation of the safety latch. Inspect for excessive wear on the sling hooks
and any side suspenders used in conjunction with the spreader bar. Check the sling retaining
disks are fitted and function as intended. Lubricate the central pivot with a light mineral based
grease or food grade spray lubricant.
• BOOM:
Check for secure attachment of the boom to the mast. Make sure the mast clamp screw
can be fully tightened and prevents disconnection of the boom from the mast. Check the boom
raising and lowering is smooth and unhindered. Lubricate all pivot points as necessary with a
light mineral based grease. Check for full engagement of the boom ram pin with the hydraulic
ram top. Make sure the boom ram pin is free to pivot on the mounting brackets. Lubricate if
necessary with a light mineral based grease.
• CHAIR SUPPORT TUBE:
Confirm the chair support tube is free to rotate but can be prevented from
rotating by tightening the support tube clamp screw. Confirm correct operation of the safety latch
securing the tube to the boom. Lubricate pivots as necessary using a light mineral based grease.
Check the function of the chair retaining latch and ensure the latch pivot is free and lubricated.
• CASTORS:
Check all castors for firm attachment to the chair legs. Check for free rotation of the
castor and the wheels. Remove any build up of threads, hair or fluff. Lubricate if necessary with a
light mineral based grease or food grade spray lubricant. Check correct operation of the brakes.
• HYDRAULIC UNIT:
The hydraulic unit should require no maintenance other than checking for
correct operation in both directions and leakage of hydraulic fluid. Additionally, check the ram for
trapped air/sponginess.
• MAST:
Examine the mast, particularly at the base, for corrosion or rusting. Check the mast
rotates freely in the floor socket. Lubricate with a light mineral based grease as necessary.
Check the mounting of the hydraulic unit to the mast. Make sure the hydraulic unit pivots freely.
Lubricate if necessary using a light mineral based grease.
Following the 6 monthly load test
conducted at maximum safe working load, examine the mast for deformation, particularly
at the base.
• GENERAL:
Check all nuts and bolts for tightness. Tighten if necessary.
• LOAD TEST:
The maximum safe working load test should be carried out at each and every
6 monthly inspection in accordance with the manufacturers test procedures. It is strongly
recommended the testing is carried out by an authorised service dealer.
• CERTIFICATION:
An authorised service dealer will issue a test certificate after satisfactory
completion of the load test. This certificate will be valid for six months.
