The rolling, flat-free tires and brake casters provide improved mobility and stability across uneven surfaces, making it a practical option for field maintenance, remote service, or temporary hydraulic fluid replenishment. While portability is the standout feature, the caddy’s overall design supports quick, clean transfers with minimal downtime.
Considerations for use include the pump type, fluid compatibility, and transport logistics. This option is most suitable when mobility and on-site transfers are a priority, rather than fixed-plant reservoir duties. It complements fixed 50 gallon reservoirs where supplemental transfer capability is needed.
Key considerations:
- Portability: Wheels and brake casters for easy maneuvering
- Transfer: Rotary pump supports controlled dispensing
- Capacity: 50 gallons for substantial on-site storage
- Fluid compatibility: Ensure hydraulic oil suitability for your system
Jobox Crescent 50 Gallon White Square Steel Tank

The Jobox Crescent 50 gallon steel tank is designed for truck-mounted liquid transfer with practical features for reliability. Internal baffles help manage flow and reduce sloshing during motion, which supports smoother pumping and consistent supply under dynamic conditions.

Key aspects to consider include internal baffles for flow control, mounting versatility, and service practicality. The Crescent design aligns with heavy-duty hydraulic applications that require dependable performance and straightforward integration into existing truck or equipment configurations.
Buying Guide: Key Considerations For 50 Gallon Hydraulic Tanks
When selecting a 50 gallon hydraulic reservoir, consider these dimensions to ensure optimal compatibility and performance:
- Material and weight: Aluminum models offer lighter weight and heat dissipation; steel variants prioritize durability.
- Mounting configuration: Upright designs save space behind the cab; saddle or underbody mounts may suit different vehicle layouts.
- Heat management: Internal baffling and radiator-like cooling help maintain hydraulic fluid temperature under load.
- Port layout: Return and suction port placement affects plumbing simplicity and routing flexibility.
- Serviceability: Sight gauges, mounting hardware, and easy access for inspection reduce downtime.
- Durability: Corrosion resistance is important for long-term operation in harsh environments.
- Maintenance considerations: Access to drain, fill, and pump mounting areas influence lifecycle maintenance.
- Port compatibility: Confirm NPT sizes and thread types match your pump and hoses.
- Compatibility with fluids: Verify hydraulic oil compatibility and any additives that may affect seals and materials.
In evaluating options, balance weight, durability, and mounting convenience with the specific duty cycle of your fleet. For applications requiring maximum portability, a rolling caddy or compact saddle option can complement a fixed 50 gallon reservoir. For routine, high-demand hydraulic systems, prioritize baffled designs and steel or reinforced aluminum bodies to reduce slosh and extend service life. Finally, verify installation requirements, warranty coverage, and service support from the manufacturer to ensure reliable long-term operation.
