Send Liftech the building location, number of floors/stops, shaft width and depth, pit depth, overhead height, required capacity and intended application — by phone or WhatsApp at +92 333 4455325 or through the website enquiry form. A site survey is recommended for an accurate technical proposal.

Important information includes: number of floors, number of stops, shaft width, shaft depth, pit depth, overhead, floor-to-floor height, required capacity, required speed, door width, building use, expected traffic, machine-room availability, electrical supply and architectural requirements.

Liftech supplies passenger elevators (450–1600 KG, 1.0–2.5 m/s), home lifts (250–400 KG, 0.4 m/s), hospital bed lifts (1600–2500 KG, 1.0–1.6 m/s), heavy-duty cargo lifts (2000–5000 KG, 0.25–0.63 m/s), commercial high-rise group control systems (up to 8 cars, 2.5+ m/s with destination dispatch), plus EN 115-1 escalators and moving walks (600/800/1000 mm step width, 30°/35° incline, 0.5–0.75 m/s).

An MRL (machine-room-less) elevator uses a compact permanent-magnet synchronous gearless traction machine mounted inside the shaft at the top overhead, eliminating a rooftop machine room. It reclaims 6–9 m² of built-up area per shaft, cuts civil cost, reduces energy use by 30–45% versus a geared machine, runs 5–10 dB(A) quieter, and eliminates gear-oil maintenance.

Geared machines use a worm/helical gearbox between the motor and sheave, run at 0.63–1.75 m/s, cost less upfront but consume more energy and require gear-oil changes. Gearless PM machines couple the motor directly to the sheave, run at 1.0–8.0 m/s, deliver smoother ride quality (typically ≤15 mg horizontal vibration), and are the current EN 81-20/50 baseline for new mid- and high-rise buildings in Pakistan.

Whenever stretcher, wheelchair, or hospital-bed access is required — hospitals, diagnostic imaging centres, dialysis units, senior-living, ICU floors. Bed lifts have 1100–1400 mm clear door opening, 1400–1800 × 2400–2700 mm cabin, ARD, precision leveling within ±3 mm, silent VVVF drive, stainless steel AISI 316 or antimicrobial PVC-coated walls, and independent-service and hospital-priority operation.

Textile mills, denim and knitwear units, cold storage, warehouses, food processing plants, automotive assembly lines, packaging plants and multi-storey retail back-of-house. Liftech cargo lifts range 2000–5000 KG with reinforced sling, T89–T125 guide rails, 12–13 mm 8×19 Seale steel wire ropes, bi-parting or vertical roller-shutter doors, load-weighing overload sensors and Class A2 fire-rated landing doors on request.

Traction (gearless or geared) is preferred for 4+ stops, higher speeds (≥1.0 m/s) and continuous duty — lower operating cost and no hydraulic oil handling. Hydraulic elevators suit low-rise (2–4 stops) applications with heavy loads, no overhead machine-room space, and low duty cycle; they consume more energy per trip and require oil temperature control in Karachi's summer. Liftech recommends gearless MRL traction for 95% of Pakistani mid-rise projects.

600 mm — one-person light-duty (offices, boutique retail). 800 mm — one-person with parcels (mid-sized malls, supermarkets). 1000 mm — two persons side-by-side (heavy-duty malls, metros, airports, transport hubs). All Liftech escalators are engineered to EN 115-1 with 30°/35° incline options, auxiliary brake, step-level monitoring, skirt-safety switches, comb-plate impact switches and handrail-entry safety.

Instead of press-and-wait, passengers key their destination floor at the lobby; the group controller assigns the elevator that minimizes system-wide travel time, groups passengers by destination, and pre-positions idle cars. Field data across our Karachi and Lahore installations shows 25–40% reduction in average waiting time, 15–25% shorter journey time and 8–15% lower kWh/trip through better load distribution and regeneration capture.

Indicative supply-and-install prices in Pakistan: passenger elevators PKR 3.8M–6.4M (630–1000 kg, 5–8 stops, MRL gearless, standard SS 304 cabin); home elevators PKR 2.4M–3.6M; hospital bed elevators PKR 5.6M–9.2M; cargo and freight elevators PKR 4.2M–8.2M; dumbwaiters PKR 0.85M–1.65M. Final pricing depends on load, travel, stops, speed, cabin specification and site conditions — request a formal quotation for your project.

An MRL (machine-room-less) elevator typically costs PKR 3.9M–7.2M supplied and installed (630–1275 kg, PMSM gearless machine, 5–8 stops). Although the equipment price sits slightly above a comparable machine-room elevator (PKR 3.6M–6.8M), the MRL option saves the machine-room civil work — reclaiming 6–9 m² of built-up area per shaft — and cuts energy use by 30–45%.

An MRL elevator mounts its compact permanent-magnet gearless machine inside the shaft overhead — no machine room, lower civil cost, quieter operation and no gear oil. A machine-room elevator houses its machine (geared or gearless) in a dedicated room above the shaft: it supports larger capacities (1600 kg and above), higher speeds (2.5 m/s and beyond), easier maintenance access and better heat dissipation. MRL suits mid-rise residential and commercial buildings; machine-room remains standard for high-rise and heavy-duty applications.

A home elevator of 250–400 kg rated load, 0.4 m/s speed, 2–4 stops, with an MRL gearless drive (or hydraulic for 2–3 stops), 900–1100 mm clear door opening and ARD rescue is the typical choice for Pakistani homes. It needs a shaft footprint of roughly 1300–1800 mm, no machine room, and runs on a standard single-phase supply. Prices typically fall in the PKR 2.4M–3.6M band.

A hospital bed elevator — 1600–2500 kg rated load, 1100–1400 mm clear door opening, 1400–1800 × 2400–2700 mm cabin, precision leveling within ±3 mm, silent VVVF drive, ARD, stainless steel AISI 316 or antimicrobial walls, and independent-service and hospital-priority operation. These enable direct stretcher and bed transfer and meet EN 81-70 accessibility requirements.

For offices and commercial buildings: 630–1600 kg passenger elevators at 1.0–2.5 m/s with group or destination-dispatch control, EN 81-70 accessibility features and IP54/IP41-rated equipment. Above 8 stops, a formal traffic study sizes the number of cars, capacity and control strategy — destination dispatch typically cuts average waiting time 25–40% in Grade-A towers.

Start with building use, number of floors/stops, expected peak traffic, required capacity and speed, door width, machine-room availability, shaft dimensions, electrical supply and budget. Send these to Liftech for a technical proposal; for buildings above 8 stops, hospitals and hotels, a formal traffic study is recommended before civil design is frozen.

Indicative EN 81-20 shaft dimensions: 630–1000 kg passenger MRL — shaft approximately 1600–2000 mm wide × 1800–2200 mm deep, pit 1200–1600 mm, overhead 3200–3800 mm. A 1600 kg hospital bed elevator needs roughly 2300 × 2400 mm. Final shaft, pit and overhead dimensions are confirmed in Liftech's shaft-fit drawings — never finalize civil work before the drawing is approved.

Monthly scheduled preventive visits, checklist-based servicing of traction machine, brake, ropes, sheave grooves, guide shoes, doors and door operator, VVVF drive, controller and safety chain; ARD functional test, safety-gear and overspeed-governor inspection, rope-tension equalization, gear-oil check (geared), COP/LOP function test, 24/7 breakdown response with defined SLA, quarterly ride-quality (vibration/A95) and error-log reports, and genuine spare parts per OEM schedule.

Modernization retains the shaft, sling, guide rails, counterweight frame and cabin shell — replacing only the controller, VVVF drive, door operator, ropes, ARD, safety gear, COP/LOP and cabin finishes. It restores factory ride quality, achieves EN 81-20/50 compliance and cuts energy use 30–45% at 40–60% the cost and 15–25% the downtime of a full replacement.

High-traffic commercial and hospital lifts — every 30 days. Residential lifts — every 45–60 days. Cargo and industrial lifts — every 30 days with load-cycle logging. After year 8, add semi-annual audits of rope wear (broken-wire count per lay length per EN 12385-5), sheave-groove profile, brake-lining thickness, contactor pitting and controller electrolytic capacitors.

Karachi, Hyderabad and interior Sindh from the head office; Lahore, Faisalabad, Multan, Sialkot, Gujranwala and Bahawalpur from the Lahore office; Islamabad, Rawalpindi, KPK (Peshawar, Abbottabad) and northern Punjab from the Islamabad office. Nationwide dispatch coordinated by the Karachi Network Operations Centre.

6–12 stop mid-rise: 30–55 working days from shaft-ready date — 3–5 days for scaffolding and rail-plumbing, 8–12 days for mechanical erection (machine, sling, doors), 5–8 days for electrical wiring, 4–7 days for adjustment and 2–3 days for third-party load testing to EN 81-20/50 clauses 5.6 (car safety) and 5.11 (electrical). High-rise or group control adds 15–25 days for commissioning.

A traffic study models passenger arrival rate, interval, handling capacity and average waiting time using RTD3 or Elevate simulation. Required for all buildings above 8 stops, hospitals, hotels and any Grade-A office tower. Output specifies the number of cars, capacity, speed, control strategy (collective, group, destination) and lobby layout — before civil design is frozen.

ARD is a battery-backed inverter that on power loss detects the lightest travel direction and drives the elevator to the nearest floor at 0.15–0.30 m/s, opens the doors, then powers down. Mandatory under EN 81-20 and Pakistan Building Code good practice for every occupied-floor lift. Liftech specifies 1P or 3P ARD units sized for full rescue plus 30–60 minute standby for Pakistan's extended outages.

High-traffic commercial and hospital lifts: preventive service every 30 days. Residential lifts: every 45–60 days. Cargo and industrial lifts: every 30 days with load-cycle logging. After year 8, add semi-annual audits of rope wear (broken-wire count per EN 12385-5), sheave-groove profile, brake-lining thickness and controller components.

Typical modernization scope: controller (e.g. Monarch NICE 3000+), VVVF drive, door operator, wire ropes, ARD, safety gear, COP/LOP fixtures, load-weighing and cabin finishes — while retaining the shaft, sling, guide rails, counterweight frame and cabin shell. It restores factory ride quality, achieves EN 81-20/50 compliance and cuts energy use by 30–45% at 40–60% of the cost of full replacement.

Every Liftech elevator is engineered to EN 81-20:2020 (safety rules for construction and installation) and EN 81-50:2020 (design rules, calculations, examinations and tests), plus EN 81-28 (remote alarm), EN 81-70 (accessibility for persons with disability), EN 81-72 (firefighters lifts) and EN 81-73 (behaviour of lifts in the event of fire) where applicable. Escalators follow EN 115-1:2017. Optional certifications: ASME A17.1 for North-American-spec projects, ISO 9001:2015 quality management and PEC (Pakistan Engineering Council) electrical and structural sign-off.

EN 81-20 covers construction/installation: car and counterweight guiding, safety gear engagement at overspeed, UCM (Unintended Car Movement) protection, door interlocks with monitored contacts, machinery-space safe access, buffers, escape and rescue. EN 81-50 defines the design rules and type-tests — rope factor of safety ≥12, guide-rail stress and buckling calculations, buffer stroke, safety-gear friction, and third-party test methodology. Together they replaced EN 81-1/2 as the current European baseline.

At handover of every new installation (125% rated load static, 110% dynamic per EN 81-50 §5.6/5.7), after any major modernization, after rope replacement, after safety-gear or governor overhaul, and typically every 5 years for commercial lifts per building consultant, insurer or PEC-registered inspection body requirement.

EN 81-70 sets accessibility rules for persons with disability: minimum 1100 × 1400 mm cabin (Type 2), 900 mm clear door opening, tactile Braille buttons at 900–1200 mm height, mirror for wheelchair reversing, audible floor announcement, handrail at 900 mm and re-open photocell. Increasingly specified by hospitals, universities, Metro/BRT stations and Class-A commercial towers in Pakistan.

Every project ships with a compliance dossier: shaft-fit and rail calculations, EN 81-20/50 conformity checklist, factory test certificates for machine/controller/ARD/governor, 125% static and 110% dynamic load-test report, ARD activation report, brake torque test, insulation-resistance and earth-continuity test, PEC-registered engineer sign-off, spare-parts list, wiring diagrams and O&M manual.

Karachi coastal sites and basement machine rooms see condensation, salt-laden air and dust. Liftech specifies IP54 door operators and IP41 controller cabinets as standard, with IP55 landing-door junction boxes on ground-floor entrances directly exposed to the outside atmosphere — extending contactor and PCB life 2–3× versus commodity units.

EN 81-72 firefighters lift (2h fire-rated shaft, dual power supply, fireman switch, hoistway pressurization interface), EN 81-73 (return-to-designated-floor on fire alarm signal, then park with doors open), and locally NFPA 72 alarm interface where the consultant specifies. Liftech configures the controller I/O for BMS/FAS handshake as part of standard commissioning.

Monarch NICE 3000+ and NICE 5000 controllers, Fuji Frenic Lift LM2A VVVF inverters, Yaskawa L1000A drives, Ziehl-Abegg ZAtop SM200/SM225 gearless machines, Torin gearless machines, Wittur, Selcom and Fermator door operators, Montanari geared machines, ARD (1P and 3P), Adams and Wittur safety gear, Blain oil buffers, PU energy-accumulation buffers, T70/T89/T125 guide rails, 8/10/13 mm 8×19 Seale steel wire ropes, sheaves, deflector pulleys, load-weighing devices, 3D door detectors and full stainless-steel cabin/door assemblies.

Monarch NICE 3000+ is a serial-communication elevator controller with integrated CAN-bus door interface, position/velocity closed-loop control, group-control ready and clean fault-code output — field-proven across Chinese, Turkish and European elevator brands. Fuji Frenic Lift LM2A is a purpose-built VVVF inverter with torque control at zero speed, regenerative option, wide 380 V ±15% input tolerance (critical for Pakistan's grid), and integrated brake-chopper — the industry benchmark for modernization.

Steel wire ropes (typically 8×19 Seale, 1770 N/mm² grade) are replaced when broken-wire count exceeds EN 12385-5 / EN 81-20 limits per lay length (usually 24 broken wires in 6d for ordinary lay), when rope diameter reduction exceeds 6% of nominal, when severe corrosion or crown-wire wear is present, or after 10–15 years — whichever comes first. Always replaced as a set, never individually.

From Liftech's parts division at the Karachi head office with local stocks in Lahore and Islamabad — call or WhatsApp +92 333 4455325. Every part ships with OEM certificate of origin, batch/serial traceability, type-test certificate (for safety components) and warranty. We do not supply grey-market or unbranded replicas.

Every retrofit begins with a controller/drive/door survey, hoistway measurement (guide rail gauge, DBG, overhead, pit), existing-cabin electrical audit and building-power measurement. Liftech engineers then match the Monarch/Fuji package to the sling, rail T-profile, motor kW/rpm and encoder resolution, and validate against a commissioning checklist (no-load run, full-load run, safety-gear drop test, brake torque, ARD activation) before handover.

A UPS keeps controller electronics alive but cannot move the car. An ARD (Automatic Rescue Device) is a battery-backed inverter that detects the lightest travel direction on power failure, drives the traction machine at 0.15–0.30 m/s to the nearest floor, opens doors and then shuts down. ARD is mandatory under EN 81-20 for any occupied-floor lift; UPS-only is not compliant.

Sheave groove profile determines rope traction (Eytelwein T1/T2 ratio); undercut U-grooves wear to semi-circular over time, reducing traction below EN 81-50 requirements and causing rope slip on emergency stops. Brake linings must retain ≥125% rated-load holding torque with one shoe disabled per EN 81-20 §5.9.2.2.2.1. Both are inspected on every AMC visit and re-machined or replaced before they fall out of tolerance.

Head office at Office No. A06, 1st Floor, Plot No. 16, Main Saba Avenue, Near Avenue Park, DHA Phase 6, Karachi — housing engineering, project management, the parts warehouse and the national 24/7 dispatch centre. Regional offices in Lahore (Gulberg III) and Islamabad (Blue Area) hold local parts stock and installation crews.

Karachi's coastal humidity (60–85% RH), airborne chloride, dust load and unstable grid demand AISI 316 stainless steel landing doors on exposed lobbies, IP55 external junction boxes, sealed door operators, VVVF drives with 380 V ±15% tolerance, and ARD units sized for 30–60 minute rescue duty. Liftech's Karachi engineering team specifies to these conditions by default.

The Lahore regional office covers Punjab (Lahore, Faisalabad, Multan, Sialkot, Gujranwala, Bahawalpur) and the Islamabad office covers ICT, Rawalpindi and KPK — both established to guarantee same-day site response for commissioning and breakdowns.

Government buildings in the Blue Area, corporate towers on Jinnah Avenue, hospitals in Sector G, and premium residential in F-6, F-7, F-8 and F-11 — including modernization of legacy Schindler, KONE and Hyundai installations from the 1990s and 2000s.

Under AMC, Liftech targets 60-minute on-site response inside city limits for entrapment calls and 4 hours for non-entrapment breakdowns, backed by remote first-response diagnostics via the Liftech IoT Smart Gateway (fault-code retrieval, controller reset, drive-parameter read) before the technician is dispatched.

Hyderabad, Sukkur, Larkana (Sindh); Faisalabad, Multan, Sialkot, Gujranwala, Bahawalpur (Punjab); Peshawar, Abbottabad, Mardan (KPK); Quetta (Balochistan); and Muzaffarabad (AJK) — served from the nearest regional office with contracted local crews for AMC coverage.
