- Easy-access filler/breather cap that can be sealed to prevent spills
- Low-profile cylinder designed for minimal axle clearance requirements
- Hydraulic fluid: MIL-PRF-5606
- CE marked
- Durable powder-coat finish (Tronair Blue)
Technical Specifications
- Rated Capacity: 50,000 lbs (22680 kg)
- Operating Temperature: −4°F to 122°F (−20°C to 50°C)
- Pressure Relief Setting: 2,500 + 250/−0 PSIG (172.4 + 17.2/−0 bar)
- Hydraulic Fluid: MIL-PRF-5606
- Jack Pad: ¾" (2 cm) spherical radius cup
- Finish: Durable powder coat (Tronair Blue)
Safety Features
- Safety Lock Valve: Prevents the jack from lowering unintentionally during lifting operations. The jack must be manually released before descending.
- Pressure Relief Valve: Prevents overload during raising operations.
- Filler Cap Seal: Easy-access filler/breather cap can be sealed to prevent hydraulic fluid spills during transport and storage.

QUESTIONS & ANSWERS
A two-stage telescoping ram allows the jack to achieve greater lifting height while maintaining a relatively compact footprint when fully collapsed. This design improves versatility when working with different aircraft types and varying ground clearances. It also enables smoother, more controlled lifting by distributing hydraulic force across multiple stages. For maintenance crews, this translates to improved efficiency and adaptability in the hangar.
The preset pressure relief valve protects both the jack and the aircraft from overload conditions by limiting hydraulic pressure. This built-in safeguard automatically prevents the jack from exceeding its rated capacity, reducing the risk of structural damage or sudden failure. According to the manual, improper adjustment or failure of this valve can affect lifting performance, underscoring its importance for safe operation. This feature is critical for maintaining consistent and reliable lifting performance.
Opening the reservoir vent screw allows proper airflow into the hydraulic system, ensuring smooth fluid movement during operation. If the vent remains closed, pressure imbalances can occur, leading to erratic lifting or failure to raise the load. The operating instructions specifically emphasize opening the vent before use to prevent these issues. This simple step helps maintain consistent hydraulic performance and prevents unnecessary wear.
A low closed height allows the axle jack to fit under aircraft with limited ground clearance, such as regional jets or business aircraft. This reduces the need for additional lifting equipment or repositioning, saving time during maintenance procedures. It also improves accessibility in tight working environments where space is limited. As a result, technicians can perform jacking operations more efficiently and safely.
Buna-N and other sealing components are essential for maintaining hydraulic pressure and preventing fluid leaks. Damaged or worn seals can lead to lifting issues or failure to support loads. High-quality seals ensure long-term reliability and consistent performance under demanding conditions. Regular inspection and replacement of seals help extend the jack's service life.
Routine inspections help identify potential issues such as loose fasteners, fluid leaks, or worn components before they lead to failure. The manual recommends checking fluid levels and the overall condition prior to each use. These proactive measures reduce downtime and improve operational safety. Consistent inspections are especially important in high-use maintenance environments.
The availability of OEM replacement kits, including pump and seal kits, makes it easier to maintain and service the jack over time. The parts list section highlights specific kits designed for cylinder seals, reservoirs, and pumps. Using manufacturer-approved components ensures compatibility and performance consistency. This support extends the equipment's lifecycle and protects the investment.
Regular load testing verifies that the jack can safely handle its rated capacity and perform as expected under load. The manual recommends annual testing and cautions against exceeding 110% of the rated capacity during testing. This process helps detect internal wear or hidden issues that may not be visible during routine inspections. Load testing is a key part of maintaining compliance and ensuring safe aircraft maintenance operations.
