ATTACHING THE CASE CLAMSHELL FOR ROAD TRAVEL

IMPORTANT: (Specific to Germany), when travelling on the road, machines equipped with CASE clamshells must be driven without these tools. You must remove these tools before travelling on the road. This procedure for attaching the clamshell is given for a machine equipped with a 2.10m dipper, with bucket cylinder and bucket control and a set of 10.00-20 tyres.

PDH1080

Hook the teeth of both shells onto the bar (1) by operating the boom cylinders, the boom articulation cylinders, the dipper cylinders and the clamshell closing cylinders at the same time. The attachment will be within the approved road travel overall dimensions when the boom cylinders and boom articulation cylinders are completely extended.

STEP 4

Lock the boom and dipper positions using the boom and dipper locking valves. See “Boom locking valve” and “Dipper locking valve” in the “Controls/Instruments/ Accessories” Section. 3 2

PDH1082 Turn the clamshell so that the clamshell teeth are parallel with the face of the stabilizer beam. Install the clamshell support (1) on the fittings provided for that purpose on the beam. Install the four retaining pins (2) and their split pins.

PDH1083 Raise the clamshell and open it so that it is above the support.

STEP 3

PDH1084 Using the boom and dipper, bring one shell of the clamshell in contact with the front support on the undercarriage.

With articulated boom

PDH1085

Extend the boom cylinders and swing the clamshell around the support by operating the boom articulation cylinders and the dipper cylinders simultaneously. The attachment will be within the approved road travel overall dimensions when the boom cylinders and boom articulation cylinders are completely extended and the clamshell beam is in contact with the stabilizer beam.

STEP 5

Lock the boom and dipper positions using the boom and dipper locking valves. See “Boom locking valve” and “Dipper locking valve” in the “Controls/Instruments/ Accessories” Section.

PDH1086 For the work position, remove the pins (1) and then tilt the support forwards. Lock the support with one of the pins.

P2AL Version

STEP 1

PDH1088 Raise the clamshell and open it so that it is above the support.

STEP 3

PDH1087 Turn the clamshell so that the clamshell teeth are parallel with the face of the blade. Install the support on the blade after pulling the retaining pins out of the blade support rods. Reposition the retaining pins and split pins in their initial position.

PDH1089 Using the boom and dipper, bring the shell beam, located towards the operator’s compartment into the housing provided for it on the support.

With articulated boom

PDH1090

Extend the boom cylinders and swing the clamshell around the support by operating the boom articulation cylinders and the dipper cylinders simultaneously. The attachment will be within the approved road travel overall dimensions when the boom cylinders and boom articulation cylinders are completely extended and the clamshell beam is in position in its housing on the support.

STEP 5

Lock the boom and dipper positions using the boom and dipper locking valves. See “Boom locking valve” and “Dipper locking valve” in the “Controls/Instruments/ Accessories” Section.

PDH1091 For the work position, tilt the support towards the undercarriage until it is stopped by the blade support rods.
