Crane tenders that name a KST crane control joystick usually mean a chair-mounted master layout — left/right armrest sticks for hoist, trolley, and slew — not a single catalog SKU sitting on a desk [Source: Gessmann KST crane control / operator-chair programs; gessmann.com multi-axis V11 product context]. Buyers educated by KST and Gessmann chair packages evaluate reach envelope, vibration isolation, and axis count together. Trunsin focuses on the sticks: AT16 and AT20 for armrest or standalone pulpit mounts, paired with seat OEMs when the tender bundles the chair.
For seat-side ergonomics and armrest geometry, start with crane operator chair joystick and crane cabin operator seat specification. This article answers the RFQ question: chair-mounted master vs standalone AT16 when the bid text says “KST.”
KST crane control joystick — chair master vs standalone AT16
| Decision | Chair-mounted master | Standalone AT16 / AT20 |
|---|---|---|
| When tenders say “KST” | Default expectation — sticks in armrests of operator chair | Acceptable when pulpit already has a fixed console |
| What Trunsin supplies | AT16/AT20 + grip modules mapped to seat OEM mount | Same sticks on pedestal or console plate |
| What partners supply | Seat frame, rotation lock, vibration mounts | Console fabrication if no chair package |
| Axis map | Typically dual masters (hoist/trolley + slew/aux) | One or two sticks per panel drawing |
| RFQ must-have | Seat OEM drawing + left/right hand layout | Panel cutout + depth clearance photo |
Honest boundary: Trunsin does not sell a branded “KST chair” as a complete seat SKU. When buyers ask for a KST crane control joystick replacement or alternative path, engineering maps the stick envelope and electrical interface to AT16/AT20 while the seat remains a partner or incumbent OEM line. Compare modular chair programs on Gessmann V11 alternative when the competitor name is on the bid.
Axis and duty checklist for KST-named RFQs
- Hoist / trolley / slew — confirm which stick owns which axis; mirror left/right for dual-chair rooms — hoist joystick controller.
- IP and duty — process and port pulpits often want IP65-class masters; see port crane joystick controller for STS/gantry notes.
- Vibration — loose armrest mounts show up as centering drift; plan fasteners and dampers with the seat OEM — centering error fix.
- Radio dual path — if portable remotes share enable logic, commission with radio remote crane joystick pairing.
When standalone AT16 is the better KST answer
Choose standalone when the cab already has a fixed metal console, when the chair is out of scope for this outage, or when the customer wants a drop-in stick swap without touching seat wiring. Many “KST” keyword searches still resolve to multi-axis masters; AT16 meets the electrical and mechanical ask if the mount drawing is clear. Use the multi-axis checklist in multi-axis crane joystick spec checklist and the application hub crane application industrial joystick guide.
For overhead bridge replacements without a full chair program, overhead crane joystick replacement is the closer cluster twin than a seat tender.
Frequently asked questions
Is AT16 a drop-in KST crane control joystick clone?
No — pinout, grip, and armrest brackets differ by seat OEM. RFQ with photos and drawings; Trunsin maps function, not brand clone geometry.
Does Trunsin sell complete KST operator chairs?
Joystick and grip focus. Complete chair bundles go through seat partners or the incumbent chair OEM; we integrate AT16/AT20 to the armrest drawing.
Chair-mounted vs floor pedestal for the same crane?
Both work. Chair-mounted matches KST-educated tenders; pedestal suits existing pulpits — send the preferred mount photo on RFQ.
How does this differ from the crane operator chair joystick article?
That post covers ergonomics and seat layout broadly. This page targets bids that literally name a KST crane control joystick and need the chair-vs-standalone decision table.
