Commissioning
The wire rope hoist has been subjected to a final inspection by the manufacturer in
accordance with the EC Machinery Directive.
WARNING
Safety hazard
.
➢
Make sure a qualified person performs commissioning.
When the hoist is commissioned and / or after a service call a comprehensive retest must
always be performed.
The following checks must be carried out:
1.
That the wire rope hoist is completed with the original accessories as supplied (e.g.
bottom hook block).
2.
Tight fit of the rope on the drum.
3.
If the fit is loose:
–
Dismount the rope guide (see page 79, section
“Removing rope guide”
).
–
Tighten up the wire rope on the rope drum and tension.
–
Mount the rope guide (see page 81, section
“Fitting rope guide”
)
.
4.
Correct selection and installation of all electrical equipment.
5.
Connecting to mains (see page 45, section
4.9.10 “Connecting to mains”
).
6.
Rope reeving, rope twist, fleet angle and angle of installation of wire rope hoist
(see page 48, section
4.11
“Reeving rope”
).
7.
The screw connections are tightened with the prescribed tightening torque.
8.
Correct functioning of runway end stops.
WARNING
Safety hazard.
On three phase hoists, it is possible to have “Reverse Phasing” causing
the block to lower when the “UP” button is dep
ressed. When this condition exists, the
hoist operation will be dangerous.
9.
The direction of motion of the load hook must correspond to the symbols on the
control pendant.
10.
Presence and correct functioning of all safety devices.
11.
Emergency hoist limit switch or combined operational and emergency hoist limit
switch, see page 72, section
7.10.6 “Setting hoist limit switch”
12.
13.
Run rope in under partial load will improve service life
(see page 48, section
4.11
“Reeving rope”
).
14.
That the electrical equipment corresponds to the technical documentation
15.
Functional test of all control functions and safety circuits (motions, brakes, emergency
stop, limit switches).
16.
Maximum working load of hoist with test loads
(crane test, see page 77, section
“Crane test”
).
–
Dynamic test: 1.1 × maximum working load
–
Static test: 1.25 × maximum working load
The test loads must be provided by the owner.
17.
Function of overload safety device
(see page 77, section
7.12 “Overload safety device”
).
The overload safety device cannot be set in the factory if it is provided by others, it
must therefore be set during commissioning.
18.
Confirm that commissioning has been duly carried out in the logbook.
