The annual preventative maintenance inspection is exhaustive. But it helps you operate your system consistently and reliably. We verify this list first-hand and in person with a technician who knows these systems like the back of their hand.
Safety inspections involve two phases: mechanical and electrical.
Rotomat Annual Safety Inspection - Mechanical
This annual inspection includes 13 mechanical systems and documentation points ranging from general condition to the fine details—things like deflection, stability, safety sign compliance, chains, shafts and tons more.
| Item |
What We Check |
Verified (Y/N) |
| Condition | Confirm overall mechanical condition and that operation matches intended use and ambient requirements (load, space, temperature, humidity). | Y/N |
| Deflection | Check for overload by inspecting carrier deflection and confirm loads are evenly distributed when loaded. | Y/N |
| Stability | Verify the unit is plumb and anchored where required per technical data; confirm anchoring is present if needed. | Y/N |
| Manuals and instructions | Ensure installation/operating instructions are complete, current, and available in the local language. | Y/N |
| Securing against falling objects | Confirm inner equipment on carriers is secured and that protruding items are detected by light barriers. | Y/N |
| Safety signs | Verify signs comply with current Hänel documentation and are intact and legible. | Y/N |
| Labeling | Check that required safety and operating labels are affixed externally, legible, and permanent. | Y/N |
| Hazard area security | Ensure panels/doors/openings require tools or are electrically locked; with multiple access points, only one may be open/active. | Y/N |
| Protection from hazardous movement | Confirm crush/cut points are guarded, safety devices cannot be bypassed by reach, and the unit cannot start unintentionally. | Y/N |
| Inner equipment | Check carrier fixtures and contents to prevent hazards caused by loose or unsecured items. | Y/N |
| Chains & shafts | Inspect carrying/drive chains and connecting shafts for wear, deformation, cracks, missing parts, and proper lubrication. | Y/N |
| Type plate | Verify plate details (manufacturer, model year, requisition, total/carrier load, electrical specs) are present and correct. | Y/N |
| Locking devices | Visually confirm both locking devices are complete, undamaged, and properly housed in their storage container. | Y/N |
Rotomat Annual Safety Inspection - Electrical
Then we move on to the electrical system, which has another layer of inspection and verification 13 points deep. Those range from lighting to weighing device evaluation to uneven load distribution warnings to emergency control devices. Critically, we make sure your emergency control devices are functioning properly.
| Item |
What We Check |
Verified (Y/N) |
| General installation | Confirm electrical equipment is suitable/certified; visually inspect wiring and record ground/insulation resistance to standards. | Y/N |
| Main switches | Verify visibility, accessibility, and lockability; note presence of separate control cabinet with de-energizing switch if equipped. | Y/N |
| Main service switch | Check visibility/accessibility/lockability; confirm out-of-view service doors are secured and carousel cannot run when switched off. | Y/N |
| Vertical motors - current load | Measure/log M1 (and M2 if present) across a full rotation and confirm balance within ±10%. | Y/N |
| Safety devices | Confirm two-piece rocker switches and ESPE type 4 light barriers/curtains function correctly (test bar per manufacturer). | Y/N |
| Command & monitoring devices | Ensure controls are accessible and clearly, permanently labeled. | Y/N |
| Operating PC location | Verify control position (at access opening or remote) complies with required guarding (light curtain or electrically locked door), or note "without PC." | Y/N |
| Lighting (optional) | Check illumination adequacy and protection from mechanical damage. | Y/N |
| Emergency controls | Test EMERGENCY STOP / red-yellow main switch functions at all access points. | Y/N |
| Uneven load measures | Confirm warning device presence and effective protection from unwanted motion; verify manual describes correct load/unload sequence. | Y/N |
| Crank (if present) | Verify coupling to drive via service door and note test only allowed when the crank is not inserted. | Y/N |
| Residual current circuit breaker (optional) | Confirm device is installed where applicable and trips when test button is pressed; note optional circuits protected. | Y/N |
| Fault memory / run log | Read and evaluate error logs (e.g., MP12N via JUMP software) and review statistics for issues tied to weighing/device performance. | Y/N |
