4.20. QUICKCOUPLING
4.20.1. QUICKCOUPLING WITH 3-SPOOL VALVE
1. HYDRAULIC SYSTEM
The hydraulic system controls the following functions of a machine:
•
raising and lowering operations of the boom and tool carrier,
•
operations of the mounted equipment.
•
locking and unlocking of the quickcoupling mounting pins,
•
securing the mounted equipment on the tool carrier.
Two hydraulic hoses supplying oil to the quickcoupling cylinders or alternately equipment hydraulic
cylinders are routed along the boom. These hoses can easily be disconnected by hand and
switched to their alternative application thanks to the quick couplers they are fitted with.
2. QUICKCOUPLING CONTROL
The quickcoupling is controlled from the operator’s cab by means of a lever. In standard version the
lever is located on the left of the bucket control lever, close to the operator. In upgraded machine, it
is located on the right of the bucket and boom control lever. The lever controls the locking and
unlocking function of the securing pins.
3. PIN LOCKING
To secure the equipment on the tool carrier (the pins in the locked position) push the lever away
from the operator’s seat. When released, the lever will automatically return to the hold position. The
pins will remain in the locking position.
4. PIN UNLOCKING
To dismount the equipment mounted on the tool carrier (the removal of the pins), pull the lever back
towards the operator’s seat. When released, the lever will automatically return to the hold position.
The pins will be retracted
5. INSTALLATION OF THE EQUIPMENT
To mount the equipment on the tool carrier, take the following steps:
•
lower the tool carrier to the same level as that of the equipment fixture,
•
drive the tool carrier onto the equipment mounting brackets,
•
set the equipment securely on the tool carrier by rolling back the tool carrier until the equipment
takes the horizontal position. In order to do so shift the bucket control lever into the roll back
position,
•
lock the equipment (see PIN LOCKING above)
6. REMOVAL OF THE EQUIPMENT
•
lower the equipment and set it level on the ground,
•
unlock the equipment from the tool carrier (see PIN UNLOCKING above),
•
shift the bucket control lever into the dumping position slowly backing the machine away so as to
drive the tool carrier away from the mounted equipment
