Outstanding power performance: Equipped with Isuzu engines, the 21-ton equipment is matched with 25-ton class power, providing strong power and excellent digging force. The bucket shaft digging force reaches 107kN, and the bucket digging force is 138kN, capable of handling various complex working conditions.
High work efficiency: The main pump has been upgraded, with the pressure increased from 34.3Mpa to 37Mpa. Combined with the electrically controlled positive flow hydraulic system, the flow distribution is reasonable, the power matching is precise, the operation speed is fast, and it can effectively shorten the construction period. It is equipped with a 1.1m³ large-capacity bucket as standard, the largest among the same tonnage, and the loading capacity is increased by more than 10%.
Strong durability: The working device is strengthened in design, with optimized hinge points and improved bucket shape to reduce digging resistance. The gear pin gasket has been upgraded to reduce the risk of bucket teeth falling off. High-strength bucket teeth, guard teeth and side teeth ensure wear resistance under harsh working conditions.
