4. COMMISSIONING AND USE
4.1 GENERAL
Check that the hook grab is in good condition.
Carefully follow the operating instructions that apply to the crane, rotator and
container to be used. If they contradict any instruction or warning in this
manual, consult your supplier.
4.2 THE ROTATOR
4.2.1 Assembling the rotator drive shaft
- Place the rotator drive shaft in the suspension plate.
- If the outside measurements of the rotator shaft do not correspond with the
inside measurements of the suspension plate, you probably have the wrong
suspension plate. If so, contact your supplier. Rotate the rotator shaft until
the hole in the rotator shaft is in front of the connector bush hole. Then
mount the suspension pin and hairpin spring.
4.2.2 Assembling the rotator with flange fitting
- If you are using a rotator with a flange fitting, the hole pattern in the top plate
must correspond with the hole pattern in the rotator.
- Attach the rotator to the top plate with a bolt joint according to the rotator
supplier’s instructions.
4.3 THE HOSES FROM CRANE TO ROTATOR
-
The rotator hose connections used for rotation are fitted with throttle valves.
The rotator should not be used without these throttle valves.
-
The hoses from the crane to the rotator used for rotation must be connected
to a connection point supplied with a throttle valve.
-
The hoses from the crane to the rotator, which are used for lifting, must be
connected to the two remaining connection points on the rotator.
Note
If it appears that the operation of the hook grab and/or rotator does not
correspond with the information given on your operating handles, the hoses
have probably been connected incorrectly.
