The Case CX330: Powerful Excavator
The Case CX330 is the upgraded excavator model to the older 9050B model. Besides its obvious increased size, the new model, Case CX330, is not just bigger, but also a progressive upgrade to the 9050B model. The newly introduced Case CX330 weighs more than the 9050B model by almost 5,000 pounds, and this extra-added weight is due to the larger counterweight it contains, and the new design of the car body that completely encloses the swing-system. This extra weight that has been added to the Case CX330 contributes to the increased power and boost in the over-front capacity. The increased boost combined with the higher level of hydraulic pressure of the travel circuit give this excavator model a 16% increased boost in the draw bar pull. All in all, it will mean more power and strength to handle poor terrain and very steep grades. Also, the new Case CX330 excavator has numerous improved features such as the enhancement of the digging linkage. The new model has an upgraded boom and arm that is deeper in the cross section and will accommodate a higher digging force. This was accomplished by incorporating a v-groove type of welding, which is put into place by robots, and then it is 100 percent ultra sound inspected. More improvements were made to the boom foot and boom to arm pivots, which now use improved brushings, new types of plated pins and new dust seals. This combines to make a more efficient and durable model, and makes it easier to care of its assembly. The new chrome pins are harder and therefore stronger, which contributes to the digging linkage durability. The standard and basic 6 cylinder and 8.3 liter engine is used in the Case CX330. This type of engine has been utilized in Case manufactured products since 1985; however through the years, this engine has undergone continual improvements and refinements that have contributed to changing about 85% of the parts that were in the original engine. Another feature of the Case CX330 is the 259 net HP, which also has an air-to-air intercooler as well as a free breathing 24 valve cylinder head. The new engines fuel system, in the Case CX330, is equipped with electronic logic that controls and tracks the operating parameters, and this will keep the system continually readied to respond with precision to the fuel requirement of each of the engines cylinders. This electronic engine design has eliminated cables and step motor controls from the fueling system, and this will add to the reliability of the engine. There have been minor changes to the Case CX330s digging linkage geometry that assist in a higher digging force, but more important changes have been accomplished in the refinement of the trench and its open center hydraulic system. These enhancements are reflected in the main pressure of the implement circuit, which is up around 8%, and the hydraulic cylinder diameter is up 7%. The Hydraulic Power in the CX330 The new model has an increase in hydraulic power that combines with the new and improved linkage geometry and will yield around 20% more force in the bucket digging, and 15% more arm force, which contributes to more efficiency. This new model also has 19 more HP, allowing the CX330 to drive the main hydraulic pumps with a more powerful force. Also, the new pumps that have been added will produce 6% more flow that will increase the hydraulic speed, but with a much lower system pressure. The newly constructed Pro Control System, or PCS, manages the hydraulic system and interfaces with the 6TAA-830 engine, and is carried out with more electronic efficiency and genius than the older model 9050B did. Thought similar to the 9050B, the new Case CX330 does contain manually selected working modes besides the electronic and automatic controlled features. The automatic mode in the Case CX330 analyzes load demands and operator input via the joystick, and will then adjust the engine and hydraulic pumps in order to balance the power and speed, allowing for more efficiency and is also better economically in the long run. The Pro Control System has other features that include high-speed assistance system that will speed up the boom and the arm functions. It also has an automatic power boost system too. The new and enhanced power boost system increases the main pressure by almost 10% for eight seconds, but only if the implement system reaches a standard relief pressure for a little longer than one second during harsh digging conditions. With all the improved and enhanced features that have been incorporated into the new Case CX330, it truly makes it the leading excavator on the market. Case works hard to outdo themselves, and this time they have succeeded by bringing to the market an efficient and exciting piece of excavating machinery. So, if you are in the market for an upgrade from the 9050B model, then you will want to definitely consider the Case CX330.
