874600-5 - Malabar 65-Ton Axle Jack – 65P10AR

The floating feature allows the cylinder assembly to articulate on a spherical bearing, enabling the ship adapter to follow the arc of the aircraft jack point during lifting. This significantly reduces side-loading stress on both the jack cylinder and the aircraft’s axle or strut. It is especially beneficial when used with compatible floating beam assemblies for aircraft in dual-flat or on-the-rims conditions.

The auto-retract system ensures the hydraulic cylinder retracts automatically after the load is lowered, reducing the risk of leaving the jack extended unintentionally. Controlled retraction also works in conjunction with the velocity fuse to prevent rapid descent in the event of a hydraulic failure. This design enhances both operator safety and equipment protection.

The Malabar 65P10AR requires MIL-PRF-5606 hydraulic fluid or an approved equivalent. The reservoir capacity is approximately 5.5 gallons, and fluid levels must always be checked with the plungers fully retracted to ensure proper system pressure and performance.

The jack incorporates a safety pop-off valve set slightly above rated capacity to prevent lifting excessive loads. In addition, a velocity fuse prevents rapid plunger retraction in the event of a hydraulic line rupture. An accumulator relief valve also protects against overpressurization of the hydraulic system.

Lowering should always be performed slowly by gradually opening the release valve to control descent speed. Rapid retraction can activate the velocity fuse, temporarily stopping movement until the system is reset. Controlled lowering protects internal seals and ensures stable aircraft support during maintenance.

Routine maintenance includes checking hydraulic fluid levels, lubricating pivot points, greasing casters, and inspecting hydraulic lines for leaks. If stored or unused, the plungers should be cycled every 90 days to keep seals conditioned. Accumulator pressure should also be verified periodically per the service procedures.

The accumulator system uses GN2 (nitrogen) and should read 140 ± 5 PSIG during inspection under normal conditions. If adjustment is required, technicians must follow the specified test gauge procedures to safely verify and recharge the accumulator to proper hydraulic pressure settings. Proper accumulator pressure ensures consistent lifting performance.

Yes, the jack supports optional equipment such as an air pump, load gauge, lubricator, and protective rain hat. These options enhance efficiency, monitoring capability, and environmental protection in demanding maintenance environments.

The jack is equipped with rear swivel casters and a retractable front caster for maneuverability. It includes a tow handle for vehicle transport and is rated for a maximum towing speed of 5 mph to prevent excessive wear or damage. Observing towing limits helps extend service life and maintain safe operation.

Malabar equipment, including the 65P10AR, carries a one-year warranty from the date of shipment under normal use conditions. The warranty is limited to repair, replacement, or refund at the manufacturer’s discretion and does not cover misuse, modification, or unauthorized repairs.
