SERVICE REFILL CAPACITIES
LOADING SHOVEL ATTACHMENTS
Boom and arm are of all-welded, low-stress, high-tensile strength steel fullbox section design. Efficient, automatic level crowding achieved by onelever control because parallel link mechanism keeps the bucket digging angle constant, and level cylinder circuit maintains the bucket height constant. (Auto-Leveling Crowd Mechanism)
Bucket (PCSA heaped 2:1 angle of repose)
BACKHOE ATTACHMENTS
Boom and arm are of all-welded, low-stress, full-box section design. Bucket of all-welded, high-strength steel structure.
