ARRANGEMENT FOR THE INSTALLATION OF THE CLAM-
SHELL BUCKET
6.9.1 DESCRIPTION AND CONTROL
6.9.1.1
VERSION WITH STANDARD CONTROLS
DANGER
•
The machine equipped with the revolving clamshell bucket cannot travel on roads.
•
The installation of the clamshell bucket must be carried out at the work site; if the machine must travel
on roads, remove the bucket.
•
The bucket can swing on the arm coupling; during use, take in consideration the increase in size due to
the swinging.
The machine can be arranged for the application of a revolving clamshell bucket on the backhoe, instead of the
standard bucket.
For the swing of the clamshell bucket an independent hydraulic circuit controlled by an additional distributor is
provided, while for its opening and closing the standard bucket opening and folding circuit is used, excluding the
control cylinder (see “6.9.2 INSTALLING THE CLAMSHELL BUCKET”).
The additional distributor that manages the swing of the clamshell bucket is controlled by means of a pedal (1)
positioned on the left side of the backhoe control lever unit.
The other controls of the backhoe movements (boom, arm and boom swing) remain unchanged (see “3.3.5.1
pos. 15-16 BACKHOE CONTROL LEVERS”).
The rotation of the bucket is controlled as follows:
1 - when the pedal (1) is pressed with the toes, the bucket swings clockwise;
2 - when the pedal (1) is pressed with the heel, the bucket swings anticlockwise.
This configuration includes also the fixed installation of the delivery and discharge pipe that convey/discharge the
oil necessary for the bucket swing and reach the proximity of the bucket connection.
