AHD Trainer

Artificial high directionals two ways — your aerial as the high point, and the portable kit. Know the parts, build the rig, see where the load actually lands, and teach the whole thing off one screen.

Open to anyone — no email, no account, nothing to install.

01

Know the kit

Thirteen cards for the Vortex — how to tell each part, what it's for, and the manufacturer's rule that governs it. Name That Part hides the names.

02

Build the rig

Any order you like or the suggested path. The ball-lock check is a step, and LOAD IT stays dead until the inspection is ticked.

03

See where the load lands

Drag the head, move a foot, guy it, and watch the resultant move. Seven portable forms, plus your aerial as the high point.

04

Teach the class

Thirty beats in teaching order. LESSON drives the screen; FREE hands you the app and the strip follows. A USB clicker runs it.

The certified easel. Force at the head, how far off vertical it acts, and whether the resultant still lands inside the feet.

Where does the resultant land?

Leg loads, guy tension and the angle band, live, on a rig you're changing while you look at it. Auto tie-backs place a splayed pair sized to bring the line of action back over the footprint — or refuse, name the guy that is missing, and say why.

The manufacturer's six-step process is the screen: mode of use, applied force, tendency of movement, securing the feet and the head, guy angles, test load.

The aerial as the high point. Driven from the pedestal: the Pierce console's levers — extend and retract, right and left, lower and raise — and the Command Zone panel reading the app's angle, length, height and reach. The setback is on the drawing.

Your aerial as the high point

Crane mode and rope-system mode are two different jobs, and the app treats them that way. Setback, tip load, the edge zone, and where the truck has to sit for the pick to work.

Five scenarios to place it against: a building, a bridge, a pier, over an object, and reaching up to a walkway from underneath a bridge.

Know the Kit. Every piece: how to tell it, what it is for, the manufacturer's own wording, and which bag it lives in.

Every number is sourced

A DATA screen with eight statuses — manufacturer text, department practice, field estimate, derived, placeholder, not-yet-sourced — so a number that isn't verified is labelled instead of hidden.

The number checks run every time the app opens and say on screen if any fail. It writes nothing to your device: no cookies, no local storage.

The full list

Know the kit
  • A parts library for the Vortex: thirteen cards — eleven parts and the two bags they come in. How to tell each one, what it's for, and the manufacturer's own rule that governs it.
  • The bags as the department packs them — three long bags and a square bag with its pin pouch and hobble bag, every part counted.
  • Name That Part — the same cards with the names hidden. A wrong tap says what you actually tapped, so time on the drill ground goes to feel instead of vocabulary.
Build the rig
  • Build it in any order you like, or take the suggested path — and the app says plainly that the path is its own, not a department order dressed up as a rule.
  • The ball-lock check is a step, not a footnote — pins through, locked, verified, with the manufacturer's own wording on the screen saying why.
  • Inspect before you load: walk the rig top to bottom, each line the manufacturer's own check. LOAD IT stays dead until every one is ticked.
  • Undo the last placement instead of starting over. Auto-build when you just want the finished rig on the screen to talk about.
Portable AHD — where does the resultant land?
  • Seven forms: tripod over the hole, the certified easel, the elevator, buttressed as an anchor and as a change of direction, and the A-frame bipod fore-and-aft and sideways.
  • Drag the head, move a foot, drag the load, guy it — and watch the resultant move with it.
  • Leg loads, guy tension and the angle band, live, on a rig you're changing while you look at it.
  • Auto tie-backs place a splayed pair sized to bring the line of action back over the footprint — or refuse, name the guy that is missing, and say why.
  • The manufacturer's six-step process is the screen: mode of use, applied force, tendency of movement, securing the feet and the head, guy angles, test load.
  • Stress test: break it on the screen instead of on the drill ground.
Your aerial as the high point
  • Crane mode — the boom moves the load — and rope-system mode — the ladder is the high point. Two different jobs, and the app treats them that way.
  • Setback, tip load, the edge zone, and where the truck has to sit for the pick to work.
  • Drive it from the pedestal, not the picture. The Pierce Ascendant and the Seagrave tiller each have their own console, drawn from their manuals: all three levers move fore and aft, and pushing forward lowers.
  • Five scenarios to place it against: a building, a bridge, a pier, over an object, and reaching up to a walkway from underneath a bridge.
  • The load path from the tip, through the change of direction, to the station — the force at each node.
  • Haul at, on the rope system: the rope down the bed to a mechanical advantage at the station, a pulley at the tip hauled straight down, or a 4:1 hung from the tip. Compare sets the three side by side — at the eyes, bending at the tip, into the turntable and at the station — every figure marked ideal, assumed or no rating.
Teach the class off this screen
  • Class Mode is a key on the home screen. It opens on where does today's class start — every beat under its part heading, nothing lit, and the clicker dead until you pick one.
  • Two ways to run it. LESSON drives the screen for you, beat by beat. FREE hands the tab bar back and you drive the app — open the square bag, switch to the bipod, put the truck up — and the teaching strip follows you there.
  • Land somewhere no beat covers and it says so and names the screen, instead of showing you the nearest teaching point as if it were about what you are looking at.
  • Thirty beats in teaching order — the bags, the parts, every configuration, the aerial — closing on what the app will not tell you.
  • Five keys above the strip — bags, kit, configs, aerial, close — one tap to that section, the one you're in lit. The outline keeps the fine grain.
  • Each beat sets its own scene: opens the bag, brings up the part, switches the rig. Then it leaves the drawing live under your hands so you can rotate it for the room.
  • In LESSON the tab bar, the clock and the footer go, the strip stands beside the drawing, and the type is sized to read from the back of the room.
  • A beat carries no rule of its own. It carries references, and the strip reads the quote and the citation off the same object every other screen reads. The only words a beat owns are the question you put to the room.
  • Next and prev, an outline to jump by, and arrow keys, PageUp, PageDown and Space so a USB clicker drives it. One mirrored screen — dongle, HDMI lead, or a share off a laptop or a phone. Nothing to pair.
Every number is sourced
  • A DATA screen with eight statuses — manufacturer text, department practice, field estimate, derived, placeholder, not-yet-sourced — so a number that isn't verified is labelled instead of hidden.
  • It lists what it is still missing and what would unlock it: the ice chart, the reach geometry, the Vortex working load. A hole stays a hole rather than getting filled with a plausible number.
  • The number checks run every time the app opens and say on screen if any fail; the full suite is a key you press. If it disagrees with itself, it says so rather than being quietly wrong.
Make it your department
  • Department profile: which aerials you run and which portable kit. Both are data — adding a truck or a kit is a data change, not a code change.
  • A SOP screen that quotes a rope-rescue SOP verbatim with the section number on every line, and puts the angle band and the rope-count rule beside the rope count the app is actually set to. It ships under the department profile; open, it opens empty, because another department’s procedure is not yours.
  • Your name on the front — the masthead carries a slot for whoever is teaching. It is the cover and nothing else: it changes no figure, no rule and no citation.
  • It writes nothing to your device. No cookies, no local storage, deliberately — a name typed into settings is gone when you close the tab, and a licensed copy carries it in the file instead.
What’s coming In development
  • More scenarios, portable and aerial both.
  • More rope-system components in the library.
  • Build the rope system onto the rig. Right now the app gets you a sound high directional. Next it carries the mechanical advantage too — rig the whole system on the screen, not just the high point.
  • Load your own department's rope-rescue SOPs, so the app quotes your book instead of the one that ships with it.
  • Your own teaching notes on each class beat — the field-practice slot is built and ships empty, waiting for the notes that come off the first class.
