6.3 CLAMSHELL BUCKET
6.3.1 DESCRIPTION AND OPERATION
DANGER
•
For the characteristics of the clamshell bucket, see “6.1.3
CHARACTERISTICS OF THE OPTIONAL EQUIPMENT”.
•
The bucket can oscillate on the arm coupling; during use,
keep in consideration the increased overall dimensions
due to the swinging.
•
Before using the clamshell bucket, make sure that the LED
positioned on the dashboard is off (see “3.3.3 pos. 12 OP-
TIONAL EQUIPMENT CONTROL SELECTION SWITCH”).
The machine is prearranged for the application of a clamshell
bucket instead of the standard bucket on the arm.
For the rotation of the clamshell bucket, an independent hydraulic
circuit is provided, while for the opening and curling of the bucket
it is possible to use the standard bucket opening and curling cir-
cuit excluding the control cylinder (see “6.3.2 INSTALLING THE
CLAMSHELL BUCKET”).
The other controls for the movements of the excavator (boom,
arm and upper structure rotation) remain unchanged (see “3.3.5
MACHINE CONTROLS”).
The rotating movements of the clamshell bucket are obtained by
means of the push buttons (1) and (2) positioned on the right joy-
stick.
The movements that cause the rotation are the following:
1 - When the right button (2) is pressed, the bucket rotates clock-
wise.
2 - When the left button (1) is pressed, the bucket rotates anti-
clockwise.
CAUTION
•
Before starting to use the clamshell bucket, make sure that
the lever of the selection valve (2) is completely rotated
clockwise and rests against its retainer.
