NMX-MGE-30 · ENGINEERED TO ORDER — MECHANICAL GROUND SUPPORT EQUIPMENT

Nothing here flies. All of it can end a mission.

Name: Mechanical Ground Support Equipment
Brand: Neometrix

Ground support equipment is the one class deliberately built to be worth less than what it holds — and where a single failure destroys an article that took years and cannot be rebuilt to schedule at any price. That inverts every normal priority. No single-point failure anywhere in a load path over flight hardware. Motion that is slow, reversible and self-locking, with hard mechanical stops behind the programmed ones, so a power failure mid-rotation just leaves the load where it is. Materials chosen so the machine can enter a clean room at all. Interfaces that put no parasitic load into a structure qualified for flight rather than for handling. And for deployment testing, gravity cancelled carefully enough that you measure the mechanism — not the rig. No delivered ground-support equipment is claimed.

Overview

The equipment is the cheap part. That is the whole problem.

In almost every other machine we build, the machine is the valuable thing and the workpiece is replaceable. Here it is exactly reversed, and the reversal is not a detail — it is the specification. It is why the design factors, the load paths, the actuation choices, the materials and the paperwork all look conservative to the point of being dull. Dull is the requirement.

Illustrative image, not a delivered system — a large plain white environmentally controlled transport container on a low wheeled steel skid frame in a clean bay: a smooth rectangular shell with heavy toggle latches along the closed seam and hinged doors at one end, four rubber anti-vibration isolator mounts visible between container and skid, substantial lifting lugs at the top corners, one small blank-faced instrument enclosure on the end wall, pale floor and white walls, no people and no markings

Fig · 02 Transport is a test — isolator-mounted, instrumented, and the recorders are read on arrival — illustrative, not a delivered system

Slow, reversible, and it holds where it stops. The operation everyone pictures — rotating an article from horizontal to vertical — is also the one that goes wrong worst. So the actuation is self-locking by construction: screw jacks, or hydraulics with pilot-operated check valves and counterbalance, never a circuit that can run away if a hose fails. Behind every programmed limit sits a hard mechanical stop, because a limit that exists only in software is a limit that exists only while the software does. The test of the design is simple: cut the power at the worst possible angle, and nothing should move.

Cleanliness is a design input, not a cleaning task. Spacecraft integrate in clean rooms classified to ISO 14644, and ordinary industrial machinery cannot go in — not because it is dirty, but because it sheds. That drives non-shedding materials, sealed bearings, silicone-free and low-outgassing lubricants, smooth wipe-down surfaces, suitable paint or electropolish, and captive fasteners so nothing can be dropped into hardware. It is the clearest reason this is a distinct discipline rather than fabrication with better paint.

The interface is the product. Equipment mates at defined hardpoints — a separation ring, lifting trunnions, thrust structure — and the engineering that matters is interface geometry, controlled load introduction, and putting no parasitic load into a structure that was qualified for flight loads, not for being picked up carelessly. Holding large geometry accurately in steel is precisely what the aerospace tooling side of this business already does.

We provide the mechanical half — design, fabrication, interface hardware, actuation, alignment, offload rigs, containers, proof testing and certification — including build to your specification and drawings. The flight hardware and the electrical ground support equipment are not ours.

Specifications

Reference equipment, built to the article.

The parameters below describe reference equipment. Capacity, geometry, actuation, cleanliness class, instrumentation and the proof-test regime all follow from three givens: the article's mass, size and hardpoint arrangement; the room it has to work in; and whether the job is handling, integration, deployment testing or transport.

Illustrative image, not a delivered system — a gravity offload deployment test rig in a clean hall: a tall square steel frame of bolted box sections carries overhead pulley blocks with thin steel cables descending to support an articulated three-segment metal leg assembly caught part way through unfolding above a flat pale floor, a small stack of flat counterweight plates hangs at one side of the frame on its own cable, a plain steel base fitting anchors the leg, white walls, bright even lighting, no people and no markings

Where ground support equipment goes wrong

Industrial design factors applied to gear that lifts something irreplaceable. Single-point failures in the load path — one hook, one sling leg, one hydraulic circuit — where redundancy or a mechanically captured path was needed. Motion that does not hold on power loss, so a controlled rotation becomes a fall. Rate limits that live only in software, with no mechanical stop behind them. Clean-room compatibility bolted on afterwards, with shedding materials, the wrong lubricants and unsealed bearings that keep the equipment permanently outside the room it was built for. Parasitic loads pushed into the flight structure through a badly located or over-constrained interface. Offload rigs with too much friction, so the deployment test measures the rig rather than the mechanism. Containers with no instrumentation, so nobody can say what the article actually experienced in transit. And proof testing skipped, undocumented, or never repeated.

So the discipline runs the other way. Load paths are redundant or mechanically captured, and every one is proof-load tested and certified with the re-test interval tracked. Actuation is self-locking and backed by hard stops. Cleanliness is decided at material-selection stage, not at handover. Interfaces are designed with the article's structural engineers so load goes in where the structure expects it. Offload systems are built for low friction and low residual restraint, and characterised so the rig's contribution is known and subtracted. Containers carry shock and tilt recorders that are read on arrival and filed with the article. And the whole package is handed over with certificates, procedures and traceable material records — which on this class is not overhead, it is the permission to be in the room.

FAQ

Common questions.

Plain-language answers from the engineering team.

Q · 01 Why is ground support equipment a specialism at all? It is only handling gear.

Because of an inversion that almost nothing else in engineering shares. In a normal factory the machine is the expensive, clever, hard-to-replace thing and the workpiece is a consumable; if a fixture damages a part, you scrap the part. Here it is exactly reversed. The fixture is ordinary steel and the article in it may represent years of work by hundreds of people, with no spare and no possibility of rebuilding it inside the launch window. That single fact reorganises every design decision. Design factors go well above industrial practice. Redundancy is required in any load path passing over the article. Motion is made slow and reversible on purpose, because speed buys nothing and costs risk. Software limits are backed by mechanical stops, because software fails in ways steel does not. Materials are chosen so the equipment can enter a clean room without shedding particles onto flight surfaces. And everything gets proof-load tested and certified, on a tracked interval, because the equipment's own certification is what allows it near the article. None of that is glamorous, and it is why general-purpose handling gear — however well made — cannot simply be repurposed for this work.

Q · 02 Why is rotating an article treated as the dangerous operation?

Because it is the operation where stored energy, changing geometry and human proximity all peak at once. As an article rotates from horizontal to vertical, the centre of gravity moves relative to the support points, the load on each actuator changes continuously and often non-linearly, and there is a range where a large overturning moment is being held by comparatively little. If anything in that chain gives way — a hose bursts, a valve fails open, a pump stops, control power drops — an uncontrolled rotation is not a jolt, it is a fall of something irreplaceable. So the requirement is stated negatively and tested that way: at any angle in the travel, remove all power and nothing may move. Meeting that is a choice of mechanism rather than a control problem. Screw jacks with an irreversible lead hold by geometry. Hydraulic circuits use pilot-operated check valves and counterbalance valves at the cylinder so a hose failure downstream cannot let the load run. Behind the programmed end-of-travel limits sit hard mechanical stops. Rotation rate is limited by the actuator's own characteristics rather than by a parameter someone could change. And the operation is designed to be stoppable and reversible at every point, so an operator who sees something wrong can simply put it back.

Q · 03 What does clean-room compatibility actually change in the design?

Far more than most people expect, and none of it can be added later. A clean room classified to ISO 14644 controls airborne particle count, and the concern with machinery is not that it looks dirty but that it generates particles and volatile contamination continuously. So: materials are chosen to be non-shedding — no bare abrasive castings, no fibrous insulation, no flaking paint, no galvanising that sheds zinc whiskers. Bearings and linear guides are sealed so grease stays inside and wear debris does not come out. Lubricants must be silicone-free and low-outgassing, because silicone contamination is notorious for migrating onto optical and bonding surfaces and ruining them. Surfaces are made smooth and wipe-down-able, with radiused rather than sharp internal corners, and finished by paint systems or electropolish qualified for the room. Fasteners are captive wherever practical, because a dropped washer near flight hardware is a serious event. Cable management is enclosed. Where equipment must cross from a dirty area, the design allows a genuine clean-down. The practical consequence is blunt: an otherwise excellent fixture built without these choices cannot enter the room it was bought for, and the fix is usually a rebuild rather than a modification.

Q · 04 Why do deployment tests need gravity cancelled?

Because the mechanism was never designed to lift itself on Earth. A landing leg, a deployable ramp, a solar array or an antenna is sized for the environment it will actually work in — micro-gravity, or a fraction of Earth's gravity — and its actuator, springs and hinges carry only the margin that environment requires. Deploy it in a workshop and it may simply not move, or move and then damage itself, and neither outcome tells you anything about whether it will work in flight. So the test rig has to carry the weight while letting the mechanism do the moving, using counterweight-and-pulley followers that track the moving part, air bearings floating it on a flat granite surface, or an overhead rig that follows the deployment path. The difficulty is that the offload system itself introduces error: friction, cable stiffness, follower lag and residual side loads all masquerade as mechanism behaviour. If those are large, the test measures the rig. So they are minimised in design and then characterised by measurement, so the rig's contribution is known and can be subtracted, and the number that comes out is the mechanism's genuine actuation margin. That is the whole point of the exercise: not to watch something unfold, but to put a defensible number on how much margin it has.

Q · 05 Why does a transport container need instrumentation?

Because transport is an uncontrolled test that the article has to pass, and without instrumentation nobody can say whether it did. Road, rail, sea and air each impose their own vibration spectrum and shock events, and the ones that matter are usually not the journey but the handling at each end — a hard set-down, a bump into a dock, a lift that swings. The article was qualified to a defined environment; if transport exceeded it, that has to be known before integration continues, not inferred later when something behaves oddly. So the container is designed as a system: an environmentally controlled shell to hold temperature and humidity and keep contamination out; the article carried on isolator mounts tuned to attenuate the frequencies that matter without introducing a resonance of their own; the whole assembly proof-tested like any other load path; and shock and tilt recorders fitted so the journey is measured rather than assumed. Those recorders are read on arrival, before the container is opened, and the record is filed with the article's history. If a limit was exceeded, that triggers inspection rather than a shrug — which is the entire value of having measured it.

Q · 06 What do you build, and what is not yours?

Divided honestly, because this field spans mechanical and electrical work and it matters which half a supplier actually does. What Neometrix provides: design and analysis, including load cases, structural analysis and the failure-mode reasoning behind redundancy choices; fabrication, machining and assembly of the structures and fixtures; the interface hardware that mates to the article's hardpoints; actuation and its hydraulics or pneumatics, chosen for self-locking behaviour; alignment and levelling systems; gravity-offload rigs and their characterisation; transport containers, isolation and instrumentation; proof-load testing, certification and the documentation pack; and installation, operator training, spares and AMC. We also build to your specification and drawings where that is the scope, which is a normal and legitimate way this equipment is procured. What is bought-in certified: hoists and chain blocks, load cells, bearings and linear guides, isolators, shock and tilt recorders, and lubricants qualified for clean-room use. What is not ours, and we will say so in a tender rather than imply otherwise: the flight hardware itself and its qualification, and the electrical ground support equipment — test electronics, checkout and automated test systems. Engineered to order; quoted across handling-fixture, integration-fixture, foldable-platform and test-jig requirements; no delivered ground-support equipment is claimed on this page.
