L
Kilometers of line, defects found only by walking it
Hundreds of idlers per line — manual patrol is needle-in-haystack; degradation goes unnoticed.

Port & conveying: one belt stops, the whole terminal slows down
Long-distance belts and handling machines run around the clock; idler, pulley and gearbox failures cause spillage, belt tearing, even fires. DHMS has a published quantified case on conveyor equipment (Anhui Mining Machinery: safety +50%, downtime −40%); Lean front-loading (Huazhiying Management & Technology) builds the planned-maintenance and spares systems — monitoring plus management keeps vessels and trains on schedule.
INDUSTRY PAIN
Three surprises that make conveyor systems accident-prone
F
A seized idler bearing means spillage, tearing, fire
Failed idler/pulley bearings generate friction heat — from spillage and blockage to belt tearing and ignition.
S
Unplanned stops delay vessels and trains
Handling follows vessel and rail schedules; a conveyor trip disrupts the plan and triggers demurrage.
HOW WE SOLVE
Get the maintenance strategy right, and every machine watched
Build planned maintenance along the whole line
Grade main and branch lines, then pair them with spot-check standards, scheduled-repair models and spares strategy — so management keeps up with monitoring data.
- Line criticality grading (main / branch / transfer points)
- Spot-check routes, standards and intervals
- Idler/pulley spares classification & safety stock
- Maintenance planning aligned with vessel/train operations
Every conveyor section reports its own health
Wireless vibration/temperature sensors on idlers, pulleys, gearboxes and motors; AI tracks bearing degradation and alerts 30–90 days ahead, linked to maintenance windows.
- Online monitoring of idlers, pulleys, gearboxes, drive motors
- Bluetooth sensors → gateway → cloud, segmented long-range networking
- Early warning before idler seizure — prevent spillage & tearing
- Alerts linked to repair plans and parts dispatch
PATH
Pilot on the worst sections, then scale to the line
01
Grade the line
Rank main lines, branches and transfer points by consequence; pick pilot sections.
02
Prepare the strategy
Sort spot-check routes, repair models and idler spares strategy first.
03
Monitor the pilot
Deploy sensors and gateways on failure-prone sections; validate alerts on real degradation.
04
Scale the line
Link alerts to repair plans and operations schedules; extend to the whole route.

FAQ
Port & Conveying: frequently asked
Hundreds of idlers — do we need a sensor on every one?
No. Use "full monitoring at critical points + graded inspection elsewhere": online sensors on drive pulleys, tail pulleys, gearboxes and motors; smart spot-check instruments and patrols for general idlers. Best ROI by design.
How does data travel back over kilometers of line?
Sensors pair via Bluetooth to nearby industrial gateways (60 sensors per gateway); gateways upload via Wi-Fi or 4G. Long lines are segmented — no cable runs needed.
Can belt tearing actually be predicted?
Tearing is usually the end state of long-term idler/pulley bearing degradation. Alerts fire weeks to months before seizure, removing the root causes; combine with longitudinal-tear detection devices for a complete defense.
Are the quantified results verifiable?
The Anhui Mining Machinery figures come from published DHMS and Industry Internet Alliance case materials (as of 2022): safety +50%, efficiency +30%, downtime −40%, maintenance cost −30%. Actual results depend on the site baseline assessment.
