How do you know when hoist ropes need replacement?

Ropes are retired on condition, not on a calendar. The criteria are qualitative — visible broken wires, measurable diameter loss, rouge from internal wear, kinks, and corrosion — applied per industry wire-rope standards. When any rope in a set reaches criteria, the whole set is replaced together so every rope shares load equally.

What is the difference between geared and gearless traction machines?

A geared machine drives the sheave through a gear reduction, suiting moderate speeds and low- to mid-rise buildings. A gearless machine couples the sheave directly to the motor, supporting higher speeds and taller buildings with fewer wearing parts but larger, heavier components.

Do traction elevators need different code tests than hydraulic elevators?

Yes. Traction units require periodic no-load and full-load testing of the governor and safeties under adopted ASME A17.1, including the five-year full-load Category 5 test. Hydraulic elevators have their own regime centered on the pressure system and valves.

Can Prime service proprietary traction controllers?

Prime services the machine, ropes, brake, governor, and safeties on any traction elevator, and works on controllers where diagnostics and parts access allow. Some manufacturer-specific controllers restrict third-party diagnostics, and Prime states plainly when a component requires OEM involvement. Where that recurs, a non-proprietary replacement controller is a practical option.

Does Prime handle machine-room-less traction elevators?

Yes. MRL units are gearless traction elevators with the machine mounted in the hoistway instead of a machine room, and Prime services them alongside conventional traction equipment. Access and suspension design differ, but the rope, brake, governor, and safety fundamentals are the same.

Is emergency traction elevator service available in Dallas–Fort Worth?

No. In Dallas–Fort Worth, Prime provides scheduled service only — planned maintenance, quoted repairs, and code testing arranged in advance. Emergency dispatch and the under-60-minute response apply to the Houston metro only.

Traction Elevator Service in Houston and Dallas–Fort Worth

Traction elevators move the car with steel ropes, a driven sheave, and a counterweight instead of hydraulic pressure, and they dominate mid- and high-rise buildings across Houston and Dallas–Fort Worth. Keeping them safe means routine attention to parts a hydraulic elevator does not have: hoist ropes, sheave grooves, machine brakes, governors, and safeties.

Prime Elevator Corp services geared and gearless traction machines under TDLR Elevator Contractor License #20478, from rope inspection and replacement to brake work, governor testing, and machine-room upkeep. This page explains the scope, the cost drivers, and how Texas compliance applies.

What is traction elevator service?

Traction elevator service is the scheduled maintenance, inspection, testing, and repair of elevators raised and lowered by steel ropes running over a motor-driven sheave. The work centers on the parts that wear under tension and friction — ropes, sheave grooves, and the machine brake — and on the overspeed protection chain of governor and safeties.

Traction elevator: An elevator raised and lowered by steel hoist ropes driven by friction over a rotating sheave and balanced by a counterweight.
Sheave: The grooved wheel the hoist ropes run over; the drive sheave transmits motor torque, deflector sheaves route the ropes.
Geared machine: A traction machine that drives the sheave through a gear reduction; typical on low- and mid-rise buildings at moderate speeds.
Gearless machine: A machine with the sheave coupled directly to the motor; used for higher speeds and taller buildings.
Governor: A speed-sensing device that trips if the car overspeeds, cutting power and setting the safeties.
Safeties: Clamping devices on the car frame that grip the guide rails and stop the car when set by the governor.

When does a building need traction elevator service?

A building needs traction elevator service on a regular schedule, and immediately when ride quality, stopping accuracy, or machine-room noise changes. Ropes, brakes, and sheaves rarely fail without warning; symptoms show first.

Reddish dust (rouge) on the ropes or in the pit — a sign of internal rope wear
Visible broken wires, flattened strands, kinks, or corrosion on any hoist rope
Car bounce at stops, or settling below floor level under load
Grinding, thumping, or rhythmic clicking from the machine room during runs
The brake drifting through stops, or repeated re-leveling at floors
Ropes riding at different heights in the grooves, or grooves worn shiny at the bottom
A governor trip or safety application — either requires inspection before the car returns to service
Gear oil leaks, overheating, or new vibration at a geared machine

What does Prime actually do on a traction elevator?

Prime maintains, tests, and repairs the complete traction system: ropes, sheaves, machine, brake, governor, safeties, drive, and controller. Maintenance is condition-driven rather than sequential, so the scope below is a checklist, not a step order.

Hoist and governor rope examination: broken wires, diameter loss, lubrication condition, and equal tension across the set
Rope lubrication and tension equalization, with full-set replacement when wear criteria are reached
Sheave inspection for groove wear, with re-machining or replacement when grooves no longer seat the ropes correctly
Machine brake inspection, cleaning, and adjustment for holding torque and smooth, accurate stops
Governor and safety examination, plus the periodic no-load and full-load tests the adopted code requires
Machine care: gear oil, bearings, and backlash on geared units; bearings, brushes, and commutators on legacy DC gearless machines
Motor, drive, and controller checks, with fault-history review where the controller supports it
Machine-room housekeeping an inspector will flag: lighting, guarding, clearances, and legible rope data tags

What equipment does traction elevator service cover?

Prime services geared and gearless traction elevators from every major manufacturer, plus legacy lines no longer built but still common in Texas buildings. That includes current Otis, KONE, Schindler, TK Elevator, Mitsubishi, and Fujitec equipment, and legacy Dover, Montgomery, Haughton, U.S. Elevator, and Delaware installations.

Traction machine types Prime services
Machine type	Where it is typically found	Service focus
Geared traction	Low- and mid-rise offices, hotels, multifamily	Gear oil and bearings, brake adjustment, rope wear, leveling accuracy
Gearless traction	Mid- and high-rise towers	Ropes and sheave grooves, brake systems, motor and drive condition
Machine-room-less (MRL) traction	Newer low- and mid-rise buildings	Hoistway-mounted gearless machines; ropes or coated suspension per design
Legacy DC machines	Older buildings not yet modernized	Motor-generator sets or retrofit drives, brushes and commutators, obsolete parts sourcing

What does traction elevator service cost?

Traction elevator service is priced from a site survey, not a rate card, because labor and materials vary widely from machine to machine. Cost turns on a handful of drivers a walkthrough of the machine room and hoistway settles quickly.

Rise and rope count — taller buildings run longer ropes and more of them
Geared versus gearless — gearless machines and their brakes are larger and heavier to work on
Rope replacement scope — ropes are replaced as a complete set, never singly, so set size drives material cost
Access and rigging — machine-room location, hoisting paths, and off-hours requirements
Parts availability — proprietary or discontinued components can require OEM sourcing or engineered substitutes
Test scope — full-load tests involve test weights and more crew time

A maintenance agreement covers routine examination, lubrication, and adjustment at a predictable recurring cost; repairs, rope replacement, and load testing are quoted separately.

How does compliance factor in for traction elevators?

Every traction elevator in a Texas commercial building must pass an annual inspection by a TDLR-licensed inspector, with the report filed to maintain a current certificate of compliance under Chapter 754 of the Texas Health and Safety Code. Traction equipment also carries periodic governor, safety, and brake tests under the ASME A17.1 code TDLR adopts. Prime performs the maintenance and testing that puts a unit in position to pass.

Annual inspection: Every 12 monthsBy a TDLR-licensed inspector — Tex. Health & Safety Code §754.019
Category 1 test: AnnualNo-load safety and governor test under adopted ASME A17.1
Category 5 test: Every 5 yearsFull-load, full-speed safety and governor test under adopted ASME A17.1
