Landing gear trolley LGX MultiSystem

palletfor aircrafthangar

Overview
LGX MultiSystem is RH Aero Systems' pallet-shippable trolley designed for ground-based removal and installation of main landing gears. Its fully electric X/Y/Z drive, integrated digital twin and single-operator HMI transform a crane-dependent, high-risk procedure into a repeatable, ground-level operation that reduces downtime and protects personnel and airframe.

Key benefits

• Save 16+ hours per main-gear change by keeping side and drag stays fitted and removing extensive rigging and preparation.
• Ground-based, all-electric control — no overhead cranes or on-wing lifting; two engineers operate via an 8" HMI touchscreen and joysticks for precise, millimetre-accurate moves.
• Universal coverage for wide-body fleets with adapter set: supports A330/A340, A350-900/‑1000, A380, 777 (including X variants), and 787 families.

Details

• 8" touchscreen + three joysticks with wired or wireless operation for precise positioning.
• Tool-Centre-Point logic lets the operator set a fixed pivot so the gear remains controlled without drift.
• Digital twin provides VR training, live load-cell readouts and remote diagnostics.
• IP54 / CE / UL rated electronics suitable for indoor hangar or apron use.
• Ships worldwide on a single ULD pallet, avoiding exceptional transport requirements.

Traditional Process (for comparison)

• Overhead sling/crane method requiring extensive rig-up.
• Wing top-skin removal often required.
• Limited controlled movement, higher risk of damage to gear and airframe.
• High manpower and tooling demands to control movements.

LGX MultiSystem Process

• Ground-based method eliminating the need for overhead cranes in most operations.
• Often avoids wing top-skin removal on composite aircraft when LGX-compatible actuator R/I adapter is available.
• Gear remains in a fully controlled position throughout operations, reducing unintended movement risk.
• Reduced manpower: typically one tool operator plus one trunnion pin R/I.

Customer story / Business impact (summary)
Field deployments at maintenance centres have shown double-digit hour reductions in downtime, elimination of crane rig-up, real-time load-cell monitoring to keep bearing loads within AMM limits, preservation of side- and drag-stay assemblies, faster return-to-service and lower labour and tooling overheads.
