Maintenance teams planning overhead crane joystick replacement on bridge or process cranes need multi-axis mechanical sticks with predictable gate feel — not consumer game controllers. Failures often combine detent wear and grip switch fatigue after multi-shift duty [Source: crane operator forum patterns].
Trunsin AT16 and AT20 cover pulpit RFQs when axis map and outputs match after drawing review. Start with crane spec checklist before quoting.
Overhead crane joystick replacement — spec dimensions
- Axis count — hoist, bridge, trolley, auxiliary
- Gate type — cross vs all-direction; friction lock on hoist
- Grip switches — deadman and rocker functions
- IP — indoor vs heat/ dust in steel mill pulpit
- Mount — panel cutout and operator reach — link crane cabin operator seat
AT16 vs AT20 for overhead duty
| Factor | AT16 | AT20 |
|---|---|---|
| Typical crane | Bridge, process, medium port | Heavy tower/port master |
| Mechanical life | Multi-million cycle class | Heavy-duty crane rating |
| Gessmann cross | V11 alternative | Large master layouts |
| RFQ | Configurator | Same PDF workflow |
Frequently asked questions
Single-unit overhead crane retrofit?
Yes for approved programs — send pulpit photos and wiring.
Replace Gessmann and S+B with one Trunsin model?
Axis map may differ — separate cross-reference per failed stick.
CAN overhead cranes?
Many pulpits remain contact/analog; CAN retrofits may use ZS40 on new ECU.
Operator seat bundled?
See crane application hub and operator-seat cluster for pulpit tenders.
