Load Testing (Electrical Variants Only)
The load test should be carried out in accordance with the manufacturers test procedures and the
directive detailed in EN ISO 10535:2006 - Annex B - Periodic Inspection B1 - see excerpt below. It is
strongly recommended that an authorised service dealer carry out the test.
EN ISO 10535:2006
Annex B
(Informative)
Periodic Inspection
B. 1 Periodic inspection of the hoist should be undertaken at the time intervals stated by the manufacturer,
but at least once a year. By periodic inspection is meant a visual examination (particularly of the hoist’s
load bearing structure and lifting mechanism with attachments, brakes, controls, safety devices and
person-support devices) and whatever function tests and maintenance measures may be required, e.g.
adjustment of brakes, tightening of fasteners.
Every inspection should include a working load test of one (1) lifting cycle with the maximum load.
Oxford electric lifts have been designed to the requirements of:
1 BS EN ISO 10535 2006 Hoists for the transfer of disabled persons
The hoists are designed to lift the Safe Working Load only. The load lifting capability is set
electronically and must not be increased as this causes excessive loading when the actuator reaches
the limits of travel. This will a󰀨ect the actuator’s useful life.
2 BS EN ISO 10535 Load Raising Test
This test is a straight forward lift of a load equivalent to the Safe Working Load, from the lowest
position to highest position of the hoist. Check that the hoist is not capable of lifting much more than
the safe working load. (A small additional lifting capability is allowable but should be no more than
15% of the SWL).
3 BS EN ISO 10535 Operator E󰀨ort Test
This test is conducted with the Safe Working Load only.
Using a force gauge (0-500N is a suitable range) push the foot pedals down and note the amount of
force necessary to open or close the legs. Maximum permissible force is 300N (30kgf / 67lbf).
Checking Welds For Fractures
NOTE: During the load testing procedure, while the lift is loaded with the safe working load, check ALL
welded joints on the lift for signs of fracture. If fractures are evident, the lift should be taken out of service
and not used until damaged components of the frame are replaced.

Oxford hydraulic lifts have been designed to the requirements of:
1 BS EN ISO 10535 2006 Hoists for the transfer of disabled persons
The hoists are designed to lift the Safe Working Load only.
2 Load Raising Test
This test is a straight forward lift of a load the equivalent to 125% of the Safe Working Load from the
lowest position to highest position of the hoist.
3 BS EN ISO 10535 Leak Test
This test is conducted with a load the equivalent to 125% of the Safe Working Load. With the hoist
in the highest working position, the hoist must maintain the lift for 15 mins. The maximum downward
movement of the hydraulic pump ram must not exceed 3mm over the 15 mins.
4 BS EN ISO 10535 Operator E󰀨ort
This test is conducted with the SWL only. Attach a spring balance (0-20 kg is a suitable range) to
the end of the crank handle and note the amount of pull necessary to operate the handle stroke.
Maximum permissible force is 120N (12.25 kg / 27 lbs).
5 BS EN ISO 10535 Descent Test
This test is conducted with the SWL only. Take the test load to the highest operating position and
measure the height of the weight from the oor. Open the release valve 1/8th of a turn. With a
stopwatch, time the descent until the weight is just clear of the oor. Stop the watch and close the
valve at the same time. Measure the distance travelled by the weight. The rate of fall must not exceed
108mm/second. Return the weight to the highest position and check that the speed of descent
increases as the valve is progressively opened.
6 BS EN ISO 10535 Operator E󰀨ort Test
This test is conducted with the SWL only. Using a force gauge (0 - 500N is a suitable range), push
the foot pedals down and note the amount of force necessary to open or close the legs. Maximum
permissible force is 300N (30 kg / 67 lbs).
7 Horizontal Boom Test
This is not a requirement of BS EN ISO 10535 but is required by users and specied by Joerns Healthcare.
With the release valve closed, pump up the unit until the boom is horizontal. Fully open the release valve.
Check: The boom must remain in the horizontal position and not descend under its own weight. Conrm the
boom will descend when additional pressure is applied by hand to the end of the boom.

Spreader Bar
CAUTION
It is not necessary to remove the spreader bar on every 6 monthly LOLER inspection.
The spreader bar should only be removed if wear is suspected on the spreader bar to boom fulcrum pin
or if wear is suspected on the main spreader bar central pivot and spreader bar central boss or if it is
necessary to replace the padded rubber moulding.
1Check the spreader bar for freedom of rotation and swing.
2Check for wear on the spreader bar to boom fulcrum pin. It is not necessary to dismantle the
spreader bar from the boom. To check for wear, whilst holding the upper portion of the central
pivot, move the pivot up and down and look for excessive movement between the spreader bar
central pivot and the fulcrum pin. If excessive wear is suspected, the spreader bar will need to be
removed for further detailed examination - see 'Spreader Bar Removal' later in this manual.
3Lubricate the joint between the spreader bar central pivot and the fulcrum pin with a light mineral
based grease or food grade spray lubricant.
4Check for excessive wear between the spreader bar and the spreader bar central pivot. To
achieve this, hold the upper portion of the central pivot steady and move the spreader bar up and
down and feel for excessive movement between the central pivot and the underside of the spreader
bar. If excessive wear is suspected, the spreader bar will need to be removed for further detailed
examination - see 'Spreader Bar Removal' later in this manual.
5Lubricate the joint between the spreader bar central pivot and the boss on the underside of the
spreader bar with a light mineral based grease or food grade spray lubricant. Take care not to
contaminate the padded rubber moulding with excessive lubricant.
6Check the spreader bar for secure attachment to the boom. Carefully examine the underside of the
boom/spreader bar assembly to conrm the spreader bar fulcrum pin has been correctly inserted
through the holes in the boom, boom end cap and the spreader bar central pivot.
