Elevator Vocabulary Cheat Sheet

The elevator industry uses terminology that can be confusing for property managers. Here are the terms you'll actually encounter in contracts, proposals, and inspection reports.

Contract Types

Full Maintenance (FM)
A service contract where the vendor handles all maintenance, repairs, and parts. Should cover everything except vandalism and acts of God. Check the exclusions list carefully -- many "full maintenance" contracts exclude major components.
Oil & Grease (O&G)
Also called an "Examination" contract. Covers only routine maintenance visits -- lubrication, adjustments, inspections. All repairs, parts, and callbacks are billed separately at time-and-materials rates. Cheaper monthly but unpredictable total cost.
Examination
Same as O&G. The vendor examines and maintains the equipment on a schedule, but any repairs are extra. Common in newer buildings where breakdowns are rare.
T&M (Time & Materials)
Billing method where you pay the tech's hourly rate plus parts cost plus markup. Used for repairs outside your contract scope or if you have no contract at all.

Service & Maintenance

Callback
Any unscheduled service visit. Someone calls in a problem, the tech responds. On an FM contract, callbacks should be included. On O&G, you pay per visit.
Entrapment
A passenger is stuck inside the elevator car. This is the highest-priority callback and typically requires the fastest response time (30 minutes to 1 hour).
NTF (No Trouble Found)
Tech responds to a callback but can't reproduce the problem. High NTF rates can indicate intermittent issues, user error, or equipment nearing end of life.
PM Visit
Preventive Maintenance visit. The scheduled maintenance your contract covers. Typically monthly or quarterly depending on equipment type and contract terms.
MCP
Maintenance Control Program. A written plan documenting all maintenance, testing, and inspection procedures for each unit. Required by code in most states. Should be kept on-site in the machine room.

Equipment & Components

Hydraulic Elevator
Elevator powered by a hydraulic piston (jack) pushing the car up from below. Common in low-rise buildings (2-6 floors). Cheaper to install but slower and limited in travel height.
Traction Elevator
Elevator powered by a motor and counterweight system using steel ropes or belts. Faster than hydraulic. Used in mid-rise and high-rise buildings. Can be geared or gearless.
MRL (Machine Room-Less)
A traction elevator where the motor sits in the hoistway instead of a separate machine room. Saves space. Common in newer construction. Maintenance can be more specialized.
Controller
The brain of the elevator. Controls all logic -- floor selection, door timing, leveling, safety circuits. Replacement costs $50,000-$70,000+. This is the most expensive single component.
Door Operator
The motor and mechanism that opens and closes the car and hoistway doors. The #1 source of callbacks on most elevators. Typical replacement: $3,000-$8,000 per set.
Hoist Ropes / Belts
Steel wire ropes (traditional) or flat belts (newer MRL units) that connect the car to the counterweight through the machine. Replacement is a major expense: $15,000-$30,000+.

Work Types

Modernization
A full rip-out and rebuild of the elevator system -- new controller, new door equipment, new fixtures, potentially new motor. This is the most comprehensive (and expensive) upgrade. Not a minor refresh.
Repair
Fixing something that's broken. A door operator fails, a relay burns out, a valve leaks. Repairs restore function. They don't upgrade or modernize.
Upgrade
Improving an individual component without a full modernization. Examples: adding a new phone line, upgrading cab lighting to LED, installing a new car operating panel.

Testing & Compliance

CAT 1 Test
Category 1 periodic test. Annual no-load safety device test. Checks that all safety equipment functions properly without putting the elevator under full load.
CAT 5 Test
Category 5 periodic test. Full-load, full-speed comprehensive safety test. Required every 5 years in most states. Tests the elevator's ability to stop safely under worst-case conditions. Expensive: $2,000-$5,000+.
AHJ
Authority Having Jurisdiction. The state or local agency that enforces elevator codes. They conduct (or authorize) inspections and issue certificates of operation.
Certificate of Operation
The permit that allows your elevator to operate legally. Issued by the AHJ after passing inspection. Must be current. Operating without one can mean fines and liability exposure.
ASME A17.1
The national safety code for elevators and escalators. Most states adopt some version of this code (with amendments). It defines minimum standards for installation, maintenance, and testing.
QEI
Qualified Elevator Inspector. A nationally certified inspector. Some states accept QEI inspections in place of state inspectors. Others (like Connecticut) do not.

Contract Terms

Evergreen Clause
A provision that automatically renews the contract for another term (often 1-5 years) unless you cancel in writing within a specific window. The #1 trap in elevator contracts.
Escalation Clause
The annual price increase built into the contract. Industry standard is 3-5%. Above 5% compounds quickly and should be negotiated down.
SLA
Service Level Agreement. Defines measurable performance standards -- response times, uptime guarantees, reporting frequency. If your contract doesn't have one, there's no accountability.
Scope of Work
The specific list of what the contract covers. Read this section and the exclusions section together. The gap between them is where surprise bills come from.
Pro tip: Print this sheet and keep it at your desk. When a vendor proposal or contract comes in, cross-reference any terms you're unsure about. Knowledge is leverage.
