Malabar 722500A-4 – 25-Ton Tripod Jack

The single-stage hydraulic design helps deliver smooth, controlled lifting performance while reducing mechanical complexity during aircraft maintenance operations. Fewer moving stages can simplify servicing and improve long-term reliability in demanding MRO and hangar environments. The design also supports positive locking at any extension height for added stability while the aircraft is elevated. These features make the aircraft tripod jack well-suited for precision lifting tasks on business jets and other aircraft platforms.

The adjustable hand pump allows technicians to adjust the handle position based on lifting conditions and the required pumping force. A shorter handle setting increases oil displacement for faster lifting under light loads, while a longer setting improves leverage during heavier lifting operations. This flexibility helps reduce operator fatigue and improve control throughout the aircraft jacking process. It also allows maintenance crews to work more efficiently during repetitive lifting procedures.

The heavy-duty swivel casters improve maneuverability when positioning the jack beneath aircraft jacking points in crowded maintenance areas. Once the aircraft load is applied, the spring-loaded casters retract automatically, allowing the jack footpads to rest directly on the ground for increased stability. This design helps minimize unwanted movement during lifting and enhances load distribution across the tripod structure. Improved stability is especially valuable during aircraft inspections, landing gear servicing, and structural maintenance procedures.

The 722500A-4 features plated, unpainted components, a hard chrome-plated cylinder bore, and Skydrol-resistant paint to help protect against corrosion and exposure to hydraulic fluid. Aviation maintenance facilities often expose ground support equipment to harsh chemicals, moisture, and changing environmental conditions. Corrosion-resistant materials help preserve hydraulic performance and structural integrity over time. This can reduce maintenance costs and extend the service life of the aircraft jack.

The Malabar 722500A-4 is factory proof-load tested at 150% of its rated lifting capacity to verify structural strength and hydraulic integrity before entering service. This testing process helps confirm that the jack can withstand demanding aircraft maintenance conditions while remaining safe to operate. Proof-load testing also supports compliance with aviation industry expectations for dependable ground support equipment. These additional safeguards help increase operator confidence during lifting procedures.

The jack is designed to tolerate side loads up to 15% of the vertical load, helping accommodate minor load variations that may occur during aircraft lifting procedures. This capability can improve stability when working on uneven hangar surfaces or during certain maintenance operations where load distribution changes slightly. Proper side-load handling helps reduce stress on the tripod structure and hydraulic system. Even with this capability, technicians should always follow aircraft manufacturer jacking procedures and ensure the jack remains plumb during operation.

The optional air-operated hydraulic pump allows technicians to raise the aircraft jack using compressed air rather than relying entirely on manual pumping. This can reduce physical strain during repeated lifting cycles and improve efficiency in high-volume maintenance facilities. Pneumatic operation also enables faster aircraft positioning for inspections and servicing. Facilities with existing compressed air infrastructure often achieve quicker, more consistent lifting performance.

The optional load gauge provides real-time load indication in both tons and PSIG, giving technicians greater visibility into lifting conditions throughout maintenance operations. Monitoring load pressure can help crews identify uneven loading and maintain safer aircraft jacking practices. This added information is especially useful during structural inspections, landing gear work, and balancing procedures. Improved load monitoring can also support more accurate maintenance documentation and troubleshooting.

Routine preventive maintenance helps preserve lifting performance, hydraulic integrity, and operational safety throughout the service life of the aircraft tripod jack. Malabar recommends maintaining proper hydraulic fluid levels, lubricating moving components, and periodically cycling the seals during storage to help prevent deterioration. The maintenance manual also outlines inspection procedures for seals, valves, bearings, and structural components to help identify wear before it leads to downtime. Consistent servicing can improve reliability and reduce long-term repair costs in aviation maintenance operations.

The optional tow handle and heavy-duty caster system make it easier to move the jack between aircraft and maintenance bays. The unit is also rated for towing speeds up to 5 mph, helping maintenance teams reposition equipment efficiently across larger hangars or ramp areas. Improved mobility can reduce setup time during aircraft servicing operations. This combination of portability and heavy-duty construction makes the jack practical for airline, corporate aviation, and MRO applications.
