Transport and infrastructure
Metro systems, rail transport, port and municipal utilities. Diagnostics of moving parts, escalators and pumping stations; CV-based control of safety and wear.
This mix delivers the most on the industry's key process stages. Details in the cards below.
Monitored machines — interactive
Escalator gearboxes, tunnel ventilation, pumping stations — equipment that works while the city sleeps. Models with measurement points — spin them.




Where Liman-Tech applies — stage by stage
For each stage: the equipment worth monitoring and what each method delivers. No fluff.
Metro: tunnel ventilation and drainage
Metro: traction substations
Rail transport and marshalling yards
Ports and transhipment terminals
Municipal and urban infrastructure
Where combined methods multiply the effect
Three rollout levels — pick by maturity
Escalators and moving systems
Main drives, gearboxes, chains
Transparency across a network of sites
Tens and hundreds of sites in a single control-room view
CV for safety
Platforms, clearance gauges, track and wagon condition
Results in numbers
- A move to condition-based maintenance instead of scheduled escalator tear-downs
- Early detection of drive defects – 2–6 months before failure
- −20–50% electricity for ventilation and pumping after switching to variable-frequency drives (VFDs)
Industry benchmarks; the actual effect depends on a site assessment at your facility.
Real case: a hardware-and-software complex for escalator diagnostics and monitoring at the Moscow Metro – in operation since 2021.
Three commercial models
From outright purchase to a service model where you pay out of verified savings.
CAPEX — purchase
You own the hardware and software — the full effect is yours. Transparent and familiar; for critical infrastructure it is the only option.
MaaS — subscription
Monitoring-as-a-Service: 36 months, a monthly base fee plus a share of the verified effect. The performance risk is ours — no effect, nothing beyond the base.
ESCO — energy performance contract
Energy-saving measures with no capital outlay on your side: we invest, repayment comes out of verified savings.
