Model 703 – 25 Ton Fixed Height Tripod Jack | Malabar

Product Description

The Model 703 Fixed Height Tripod Jack is a heavy-duty, 25-ton capacity hydraulic jack engineered for aircraft maintenance, particularly suited for mid-wing applications on large aircraft like the Boeing 747, 747SP, and 767. Its robust tripod structure features a hydraulic cylinder assembly, reservoir, valve block, and hand pump, ensuring reliable performance in demanding environments.

Key highlights include:

• Spring-loaded casters for mobility, which retract under load to stabilize the jack.

• Extended reach with a 77″ hydraulic lift and 24″ extension screw, providing a total extended height of 249″ (20.75 feet).

• Enhanced safety with dual relief valves (system + thermal) and a secondary cylinder seal for contamination protection.

• Rugged construction with corrosion-resistant plating, Skydrol-resistant paint, and a 3-year warranty.

Ideal for high-clearance aircraft maintenance, the Model 703 combines power, precision, and durability for critical lifting operations.
