Overhead and process crane cabins demand operator seats that survive bridge vibration, support precise joystick reach, and keep electrical compartments accessible without leaving the seated position. Catalog office seating fails within months; integrated crane pulpits require configuration on control console platforms such as EOS and TIA.

Vibration and rotation: paired bearings and locks
Single-bearing rotation stacks drift under crane bridge vibration. Trunsin employs paired top and bottom bearings with anti-vibration bases and rotation locks featuring adjustable wear blocks. Lock engagement is verified on video before batch release.
Joystick reach and hand rest placement
Crane operators depend on predictable reach to multi-axis industrial joystick controllers. Hand rests may land on the chair or lateral box depending on lid swing and grip orientation — evaluated in 3D against your grip model.
Cabin space constraints and line of sight
Low ceiling height, side windows, and emergency egress paths limit box depth and monitor mast height. Share cabin drawings early; inter-box spacing and box depth must allow full lid opening beside the operator seat without blocking egress.
How we validate
Cabin reference drawings drive 3D layout gate. First article covers rotation stability under vibration simulation, joystick reach with PPE, monitor line of sight, and lateral box access from seated position. Video evidence for lock engagement and box opening.
Specification checklist
| Item | What to confirm | Evidence |
|---|---|---|
| Vibration base | Paired bearings + isolation | Rotation without drift |
| Joystick reach | Grip model in 3D | Hand rest placement |
| Monitor LOS | Mast height vs windows | VESA mass checked |
| Box depth | Egress clearance | Lid swing verified |
| Electrical access | Double-bit + gas springs | Seated maintenance reach |
Frequently asked questions
How is crane cabin seating different from floor pulpits?
Vibration duty, compact volume, and line-of-sight to load dominate — box depth and mast height are tighter constraints.
What drawings should we send?
Cabin plan, elevation, joystick layout, monitor spec, and egress paths.
Can Trunsin match an existing crane OEM layout?
Yes — reference drawings drive spacing, depth, and rotation lock placement.
Does foot rest load matter in crane cabins?
Operators brace during critical lifts; foot rest structure is validated like mill pulpits — static load on gap record.
