Hydraullic Servicing Trolley – Aviation-Grade Ground Support by Jetsys Defence
The Hydraullic Servicing Trolley from Jetsys Defence delivers clean, stable, high-pressure hydraulic power for aircraft maintenance, testing, and flushing. Designed for fighter jets, transport aircraft, and helicopters, it supports continuous servicing, precise flow/pressure control, and rapid de-aeration—optimised for MROs, depots, and flight-line operations.
Key Features of Hydraullic Servicing Trolley
Dual-Circuit Performance
Two independent supply/return lines allow parallel operations such as actuator cycling, reservoir top-up, and system flushing — all without cross-contamination.Precision Control
Panel-mounted regulators and relief valves provide stepless pressure and flow control for platform-specific servicing procedures.Clean & Dry Fluid Delivery
High-efficiency filtration down to 3 μm, with optional water/air removal stages and dedicated sampling points for on-condition maintenance.
Robust Mobility
Towable chassis with leaf-spring suspension, all-terrain tires, and Ackerman steering enables safe maneuvering across hangars, aprons, and uneven tarmac.Operator-Centric Design
Large analog/digital indicators (pressure, return, boost, temperature, flow), emergency stop, guarded selectors, and clear line IDs for error-free operation.
