Hot sale HITACHI EX70N HIGH DASH TRAVEL DEVICE FINAL DRIVE RV GEAR A B | Tonkee®

High Dash Travel Device: The "High Dash" in the name suggests that this travel device is designed for enhanced performance, particularly in terms of speed and power.

This is essential for an excavator like the EX70N, as it needs to navigate rugged terrains and move heavy loads efficiently. The travel device is responsible for propelling the excavator forward and backward.

Final Drive: The final drive is the last component in the powertrain of the excavator. It takes the mechanical energy generated by the engine and converts it into the rotational force required to move the tracks or wheels. The quality and reliability of the final drive are crucial for the excavator's overall durability and productivity.

RV Gear A and B: The RV Gear A and B are components within the final drive system. The term "RV" typically refers to a type of gear mechanism, specifically a planetary gear system often used in heavy machinery like excavators. These gears are engineered to withstand the high stresses and torque loads associated with heavy-duty construction work.

Specifications: While the specific specifications of the Hitachi EX70N High Dash Travel Device Final Drive RV Gear A and B would require detailed technical documentation, some typical specifications for such components may include:

Material: These gears are typically made from high-strength, wear-resistant materials such as alloy steel to ensure longevity and durability.
Size and Weight: The exact size and weight of these components would depend on the excavator model and design specifications.
Torque Rating: They would have a specific torque rating to handle the power generated by the excavator's engine.
Sealing: Proper sealing to prevent contamination from dust, dirt, and moisture is crucial to ensure a long lifespan.
Lubrication: They may require specialized lubrication to reduce friction and heat generation during operation.
