描述

Product Introduction

The XE490DK MAX 49-ton excavator for mining reduces fuel consumption by 6% and improves efficiency by 10% compared with the previous generation. The rotating bearing ball diameter is 20% larger than the previous generation, and the raceway diameter is increased, resulting in a 15% increase in bearing capacity. Imported shock absorber with silicone oil seals improves the rigidity of the cab floor and decreases cab shaking and fatigue for the operator.

Performance Characteristics

Features of the XE490DK MAX 49-ton excavator for mining:

1. Hydraulic drive independent cooling system, suitable for high and low-temperature working conditions; the fan reversal function is convenient for radiator cleaning.

2. The larger displacement main pump and the new main valve have the characteristics of low-pressure loss, stable performance, good operation performance, and precise control.

3. Self-optimizing matching technology for crushing conditions; one-key independent matching technology is adopted for crushing operation, which can reduce fuel consumption by more than 20% on average.

4. H-type working devices, large-capacity rock buckets, and extended fixed chassis are more suitable for mining operations.

5. The air intake system is equipped with a three-stage filtration mode of oil pre-filtration, which is suitable for the dusty working environment of the mine.

6. Strengthen the lengthened drop-off, higher construction stability, and better meet the complex conditions of construction operations.
