The Hitachi ZX120 is a highly regarded machine in the world of compact excavators, known for its durability and precision in construction and digging tasks. However, like all machinery, it can sometimes face issues, particularly with its travel speed control. Travel speed is critical to the efficient operation of an excavator, affecting productivity and maneuverability on the job site. This article explores common issues related to the travel speed control of the Hitachi ZX120, why they occur, and how to address them.
Understanding Travel Speed Control in the ZX120
The Hitachi ZX120, like many modern excavators, is equipped with variable travel speed control to enhance operational flexibility. This feature allows the operator to adjust the speed of the machine depending on the task at hand, whether it’s navigating rough terrain, moving to a new job site, or working on delicate tasks that require slower movements. The control system relies on hydraulics, sensors, and the machine’s electronic control unit (ECU) to adjust travel speed.
Typically, there are two travel speeds on most compact excavators: low and high. The low-speed setting provides more torque for challenging terrain, while the high-speed setting allows for faster movement over flat, even ground.
Common Issues with Travel Speed Control
Several problems can arise with the travel speed control on the Hitachi ZX120, often causing either reduced travel speed or erratic behavior of the system. Some of the most common issues include:

1. Inconsistent Speed Response
   One of the most frequent issues with the ZX120’s travel speed control is inconsistent speed response. The machine might either accelerate too slowly or suddenly shift to a faster speed without input from the operator. This can be a frustrating issue, especially when precise movement is needed for tasks like digging or maneuvering around obstacles.
   
2. Unresponsive Speed Control
   Sometimes, the travel speed control may become unresponsive altogether. In such cases, the machine may either stay stuck at a certain speed (either high or low) or fail to change speeds even when the operator attempts to adjust them. This can render the machine ineffective for jobs requiring variable speed.
   
3. Erratic Speed Shifts
   When the operator tries to switch between low and high speeds, the machine may shift erratically, with delays or jerking movements. This is a sign that something is malfunctioning in the travel control system, such as a faulty sensor, wiring issue, or hydraulic component.
   
4. Slow or Stalled Movement
   Another issue might be that the excavator moves very slowly or seems to stall when trying to travel at a higher speed, despite being in the high-speed mode. This is often caused by problems in the hydraulic or electronic systems, including low hydraulic fluid levels, pump issues, or problems with the ECU.

Transporting heavy equipment is an essential part of the construction and mining industries. Whether you're moving an excavator from one job site to another or transporting a fleet of bulldozers across the country, understanding the cost factors involved is crucial for budgeting and planning. The cost to haul heavy equipment over long distances can vary greatly based on a number of factors, including the size and weight of the equipment, distance, route, and other logistics. In this article, we’ll explore the key components that contribute to the cost of hauling heavy machinery and provide insights into how to estimate and minimize these expenses.
Key Factors Affecting Hauling Costs
When hauling heavy equipment over long distances, the total cost is influenced by several factors. These factors not only impact the direct cost but also determine the safety and efficiency of the transportation process.
1. Type of Equipment
The type of equipment being hauled plays a significant role in determining the cost. Larger, heavier machines such as bulldozers, cranes, or wheel loaders require specialized trailers and equipment to ensure safe transport. For example, transporting a CAT D8 dozer requires a lowboy trailer with a higher weight capacity compared to a skid steer loader.
Key considerations:

• Weight and Size: The heavier and bulkier the equipment, the more expensive it is to transport. Oversized or overweight loads may require special permits or route clearances, adding extra costs.
  
• Complexity of Load: Certain pieces of machinery may need to be disassembled for transport (e.g., removing a blade or bucket from an excavator), which adds to the labor costs.
  

• Distance: The further the distance, the higher the cost. Long-distance hauls typically require additional fuel, labor, and time.
  
• Route Considerations: Routes with more obstacles, such as narrow roads, low bridges, or difficult terrain, may require specialized equipment and planning, which can increase costs.
  
• Permits and Escorts: When hauling oversized or overweight loads, certain jurisdictions may require special permits and pilot cars or escorts to navigate safely. This adds to the total cost.
  

• Flatbed Trucks: Used for smaller equipment that doesn’t require specialized transport. A standard flatbed can carry compact machinery like skid steers, mini excavators, and other lightweight machines.
  
• Lowboy Trailers: For larger, heavier equipment like bulldozers, excavators, and backhoes, lowboy trailers are commonly used. These trailers have a lower deck height, which allows for the transportation of tall and heavy equipment.
  
• RGN (Removable Gooseneck) Trailers: These trailers are ideal for extremely large or heavy equipment. They have a removable front section that allows equipment to be driven on without the need for cranes or other lifting devices.
  
• Multi-axle Trailers: Used for very heavy loads, these trailers distribute the weight more evenly and help reduce the risk of road damage. Multi-axle trailers may also require permits for road use.
  

• Fuel Efficiency: Different hauling rigs and equipment require different fuel amounts. For example, a heavy-duty truck pulling a lowboy trailer will consume much more fuel than a smaller truck transporting lightweight machinery.
  
• Fuel Prices: The volatility of fuel prices can dramatically affect the total cost of transport. This is especially true for long-distance hauls that cover many miles across varying regions with different fuel price points.
  

• Driver Fees: Professional truck drivers are typically compensated on an hourly or per-mile basis. For long-distance hauls, the driver’s time is a significant cost factor.
  
• Loading and Unloading Labor: Skilled workers are often needed to load and unload heavy equipment safely. If special tools or cranes are required, this will add to the labor costs.
  
• Escort Vehicle Operators: For oversized loads, escort vehicles are often required. The drivers of these vehicles must be compensated for their time, adding additional labor costs.
  

• Equipment Insurance: Protecting the equipment itself is vital, as it could be damaged during transit. Insurance rates depend on the equipment’s value, weight, and the type of haul.
  
• Liability Insurance: In case of accidents, liability insurance is necessary to cover damages to third parties or property. This is especially important for heavy equipment transport as the risk of accidents is higher.
  

1. Short-Distance Hauls (under 100 miles):
   • Flatbed transport: $150 to $500
     
   • Lowboy transport: $500 to $2,000
     
   • Additional costs for permits or escorts may apply
     
2. Long-Distance Hauls (over 100 miles):
   • Flatbed transport: $1 to $3 per mile
     
   • Lowboy transport: $2 to $5 per mile
     
   • Multi-axle transport: $5 to $10 per mile (depending on weight)
     
3. Special Costs:
   • Escorts for oversized loads: $100 to $300 per hour
     
   • Fuel costs: $3 to $7 per gallon of diesel
     
   • Insurance premiums: Typically 1% to 5% of the equipment value
