Fleet owners planning an electro-hydraulic joystick retrofit often want electronic cab input while keeping the main valve stack — servo actuators on manual spools rather than a full electro-hydraulic valve replacement [Source: Anderson MOD10 product documentation; Hydraulic Master Scanreco crane kits]. Trunsin supplies electronic sticks (ZS30, ZS40) that feed ECU or servo drivers; we do not supply hydraulic valves.
Read hydraulic vs electronic before scoping timeline and harness work.
Electro-hydraulic joystick retrofit — phased path
| Phase | Scope | Trunsin role |
|---|---|---|
| 1 — Audit | Valve type, pilot pressure | Stick spec + output type |
| 2 — Cab input | Electronic stick install | ZS30 analog or ZS40 CAN |
| 3 — Actuation | Servo on existing spools | Partner integrator |
| 4 — Commission | Deadband + neutral | Centering guide |
Crane programs referencing Scanreco + cross-rod kits should align stick neutral with radio interlocks — see Scanreco retrofit and radio pairing.
Output selection for retrofit ECUs
- Analog 0–5 V — legacy PLC inputs
- PWM — some servo drivers
- CANopen/J1939 — modern mobile ECUs — CANopen integration
Frequently asked questions
Does Trunsin sell MOD10 actuators?
No — we supply cab joysticks; actuation is integrator scope.
Timeline for cab-only phase?
Often 4–8 weeks ARO after configurator sign-off — valve phase varies.
Hall upgrade during retrofit?
Recommended when replacing drift-prone pots — Hall vs potentiometer.
CAN bus required?
Only if target ECU is bus-native — otherwise ZS30 analog may ship faster.
