The Genie S45 is a versatile telescopic boom lift known for its ability to reach high elevations, making it ideal for construction, maintenance, and other elevated tasks. However, like any piece of heavy equipment, the Genie S45 can face performance issues, especially related to the hydraulic system. One common issue that operators may encounter is a fade in hydraulic performance when the machine becomes hot. This article explores the potential causes of this problem, how to troubleshoot it, and solutions to restore optimal hydraulic function.
Overview of the Genie S45
The Genie S45 is part of Genie’s S-series of boom lifts, designed for applications requiring both horizontal and vertical reach. It is powered by a diesel engine and equipped with a hydraulic system that allows the boom to extend and raise the platform to great heights, providing operators with the flexibility to perform tasks like construction, inspection, and maintenance work at high elevations. With a maximum platform height of 45 feet and a horizontal reach of up to 25 feet, the S45 is a robust and reliable piece of machinery for aerial operations.
The hydraulic system in the Genie S45 plays a critical role in its functionality. It powers the movement of the boom, the lifting mechanism, and the steering. Given the machine’s heavy-duty tasks, its hydraulic system is constantly under strain. When issues arise, such as a fade in performance during prolonged use or when the system gets too hot, it’s important to address the problem promptly to ensure both safety and productivity.
Understanding Hydraulic System Fade
Hydraulic system fade is when the hydraulic power becomes weaker or inconsistent during use, especially when the system heats up. This problem can manifest in several ways, such as slower or less responsive boom movements, difficulty lifting or extending the platform, or even complete failure of hydraulic functions. In many cases, the problem is more noticeable after the machine has been running for a while and its hydraulic fluid heats up.
Hydraulic systems rely on fluid pressure to power the various movements of the lift. When the fluid gets too hot, its viscosity decreases, which can lead to a reduction in pressure, causing the machine's movements to slow down or become less efficient. Prolonged exposure to high temperatures can also damage seals, hoses, and other components of the hydraulic system, further compounding the issue.
Causes of Hydraulic Fade When Hot
Several factors can contribute to hydraulic fade when the Genie S45 gets hot. Here are some common causes:

1. Overheated Hydraulic Fluid
   One of the most frequent causes of hydraulic fade is overheating of the hydraulic fluid. Hydraulic fluid needs to maintain an optimal temperature for proper operation. If the fluid temperature rises too high, its viscosity decreases, resulting in reduced hydraulic pressure. This can cause sluggish or erratic boom movement, as well as diminished lifting capacity.
   
2. Faulty Hydraulic Fluid Cooler
   The hydraulic fluid cooler is responsible for maintaining the temperature of the hydraulic fluid. If the cooler is malfunctioning, the fluid may not be adequately cooled, leading to overheating. The cooler could be clogged, leaking, or damaged, preventing it from effectively regulating the fluid temperature.
   
3. Contaminated Hydraulic Fluid
   Contaminants like dirt, debris, and water in the hydraulic fluid can cause internal friction, leading to excessive heat buildup. These contaminants can clog filters, degrade seals, and damage hydraulic components, making it difficult for the system to maintain proper pressure.
   
4. Low Hydraulic Fluid Levels
   Low hydraulic fluid levels can cause the system to work harder to maintain pressure. This can lead to increased heat generation, especially if the system is overworked or operated for extended periods. Insufficient fluid can also cause air to enter the system, which further reduces hydraulic performance.
   
5. Worn Hydraulic Pump or Components
   If the hydraulic pump or other system components are worn or damaged, they may struggle to produce the necessary pressure to operate the lift effectively. Worn components can lead to internal leaks, reduced flow, and inefficient operation, especially under heavy load or prolonged use.
   
6. Excessive Load or Overuse
   Operating the lift beyond its rated capacity or for extended periods without breaks can lead to overheating. Overloading the boom or constantly running the machine without allowing it to cool down can put excessive strain on the hydraulic system, causing it to overheat and fade.
   

1. Check Hydraulic Fluid Temperature
   Use a temperature gauge to monitor the hydraulic fluid temperature. If it’s exceeding the manufacturer’s recommended temperature range, the fluid is likely overheating, which could be the cause of the fade. The ideal temperature for most hydraulic systems is between 100°F and 120°F (38°C to 49°C), but check the specific guidelines for your model.
   
2. Inspect the Hydraulic Fluid Cooler
   Ensure that the hydraulic fluid cooler is clean and functioning properly. If it's clogged with debris or oil residue, it will not cool the fluid effectively. Clean or replace the cooler as needed. Check for leaks that might prevent the cooler from operating as intended.
   
3. Check Hydraulic Fluid Levels
   Inspect the hydraulic fluid levels to ensure that they are at the recommended level. Low fluid levels can cause the system to overheat and reduce its performance. Top up the fluid with the recommended type, and replace any fluid that appears contaminated or dirty.
   
4. Replace Contaminated Hydraulic Fluid
   If you suspect that the hydraulic fluid is contaminated, drain the system and replace the fluid. Ensure that the system is flushed properly to remove any dirt or debris. Also, inspect and replace any clogged or worn filters.
   
5. Examine Hydraulic Components
   Inspect the hydraulic pump, valves, hoses, and seals for signs of wear or damage. If any components are worn or leaking, they may need to be repaired or replaced. Pay close attention to any areas that may be prone to leaks, such as hose connections and valve seals.
   
6. Avoid Overloading
   Ensure that the lift is not being overloaded or operated for excessive periods without rest. Always follow the manufacturer’s guidelines for weight limits and operating hours to prevent unnecessary strain on the hydraulic system.
   

1. Install a Better Cooling System
   If overheating continues to be a problem, consider upgrading the hydraulic fluid cooler or installing additional cooling systems to better regulate fluid temperature. Regularly cleaning and maintaining the cooler is also essential for optimal performance.
   
2. Use High-Quality Hydraulic Fluid
   Using high-quality hydraulic fluid that is suitable for the working conditions and temperatures can help prevent overheating and extend the life of the system. Make sure to use fluid that is compatible with the specific model of the Genie S45.
   
3. Perform Regular Maintenance
   Establish a routine maintenance schedule for the hydraulic system. This includes checking fluid levels, replacing filters, inspecting for leaks, and cleaning the system. Regular maintenance can prevent issues before they develop into more significant problems.
   
4. Monitor System Pressure
   Use pressure gauges to monitor the hydraulic system’s performance regularly. If you notice any drop in pressure, this may indicate issues with the hydraulic pump or other components that need attention.

The Role of Scrapers in Heavy Earthmoving
Scrapers are high-speed earthmoving machines designed to cut, load, haul, and dump soil in large volumes. Popular in highway construction, mining, and site development, they operate in tandem or solo depending on terrain and haul distance. Caterpillar, Deere, and Terex have dominated the scraper market for decades, with models like the Cat 627 and 637 series becoming industry staples. These machines rely heavily on tire integrity to maintain traction, flotation, and load balance across uneven ground.
Scraper tires endure some of the harshest conditions in the industry. Unlike dozers or loaders, scrapers travel at higher speeds over abrasive surfaces while carrying massive loads. Their tires must withstand impact, heat buildup, sidewall flexing, and constant torque—all while maintaining stability during loading and dumping cycles.
Tire Types and Construction
Scraper tires are typically:

• E-3 or E-4 rated for earthmoving applications
  
• Bias-ply or radial depending on machine age and operator preference
  
• High-ply count (often 20-ply or more) for added strength
  
• Tubeless with bead reinforcement for rim retention
  
• Designed for flotation to reduce ground pressure on soft soils
  

• Center tread wear from high-speed travel on hard surfaces
  
• Sidewall cracking due to flexing under heavy loads
  
• Chunking from sharp rock or debris
  
• Bead damage from improper mounting or rim corrosion
  
• Heat separation in multi-shift operations without cooldown periods
  

• Check air pressure daily and adjust for load and temperature
  
• Rotate tires between axles to balance wear
  
• Use infrared thermometers to monitor heat buildup
  
• Inspect for cuts, bulges, and exposed cords weekly
  
• Clean rims and valve stems during tire changes
  
• Avoid sudden turns or aggressive braking under load
  

• Casing integrity is intact
  
• No sidewall damage or bead separation
  
• Tread depth is sufficient for buffing
  
• Machine downtime allows for swap logistics
  

• Michelin XHA and XDR series
