Performance testing GH2 ang GH2 HD

• The performance test provides a first-hand impression

of the status of the entire system . A note is made of any
instances of non-compliance which are subsequently
investigated further during the main inspection .

• The hoist is run through the entire system by the tech-

nician, who makes a general observation of the system
while all system functions are tested .

•  Testing of up/down function .
•  Testing of drive motor, if any .
•  Checking of any undesired noises from the wheels .
•  Checking of any undesired noises from the gears/motor .
•  Testing of Combi-lock, switch tracks and turntables, if

any .

Main inspection GH2 and GH2 HD

• Remove covers and follow the procedure below, if

necessary together with the electrical functional descrip-
tion for GH2 ang GH2 HD .

• Check transformer min . 24 V AC
• Check voltage from the transformer to the charging

station, including any room-covering charging station,
thereby ensuring that the cable connections are correct .

• Check batteries:
Measure battery voltage on both batteries without load .

It must be above 12 .0V and the difference between
the two batteries must be max . 0 .3V . Now measure the
voltage with load (60-80 kg (132-176 lbs)) . The rate of
speed at which the voltage drops must be the same
on both batteries, and the difference between the two
batteries must be max . 0 .3V .

• Check emergency stop and emergency lowering

function with a load corresponding to 85 kg (187 lbs) .

• Check endstop down – first without load on the lifting

strap . It should not be possible to lower . Then test with
the weight of the lifting hanger on the strap . It should
now be possible to lower .

• Check endstop up . Run lifting strap all the way up and

against the stop . This should cause the micro switch to
stop the lifting function immediately . The same should
apply when the strap is at an angle of more than 45º
relative to the hoist lengthways and 10º crossways .

• Check lifting strap for correct installation and check

for cut threads . If the edges of the strap are very worn
due to swings or if there are any other signs of wear,
the strap should be replaced . Also check the hoist to
identify any sharp edges or burrs . Any defects must
be repaired before fitting of the new strap . Follow the
instructions on the fitting of lifting straps .

• Check trolley – as regards the fitting of the trolley to the

hoist, locking rings must be fitted at either end of the
axle which holds the trolley .

• Check coating if the hoist is coated . It must be ensured

that the coating remains functional . If not, the hoist must
be recoated using Silicone Spray – Sil Slip A .

• Fit covers .
• Carry out performance test of the entire system with

rated load .

Rail system in general

• Carry out a performance test of the entire system with

rated load .

• Check that the system is completely level .
• Check the bracket to ensure it has been correctly

tightened .

• Check rail connections to ensure correct positioning

of cylinder pins and rail connectors .

• Retighten all endstops and check for installing safety

split pin .

• The rail system should be marked with the maximum

load, cf . the distance between the fittings .

Combi-locks

• Function test, including checking the diode function on

the manual control .

•  Check transformer, 24 volt AC .
•  Check attachment to rail (remove covers) .
•  Check that the tongue does not subject the safety lock

on the traverse rail to a maximum load – the safety lock
must not fully open . If this is the case, the Combi-lock
must be adjusted .

• Both safety locks must be checked manually and

electronically – must return normally without problems .

Switch track manual/electrical

• Function testing .
• Check transformer 24 V AC .

Turntable

•  Function testing .
•  Check transformer 24 V AC .
•  Check endstop function – the turntable rail must be

completely in line with rails on either side of the turn-
table . If this is not the case, the rail system must be
adjusted, and if the turntable turns too much, the cover
plates must be removed and the end stop adjusted .
