Hey everyone, it\u2019s Jake, and for the last three years I\u2019ve been running a small, specialty parts supplier that works directly with BLT (that\u2019s British Lift Technologies, for anyone who doesn\u2019t know the shorthand we use on our production floor). Most days, I\u2019m on the phone with their maintenance crews, their parts managers, even the on-site techs who are yanking old elevator parts out of buildings in Manchester or Birmingham and slapping our replacements in. The question I get asked more than any other these days is: \u201cJake, how do we actually measure if the elevator parts you\u2019re supplying us are efficient?\u201d It\u2019s not a vague \u201chow good are these parts\u201d question\u2014BLT has concrete uptime goals, energy budgets that get audited every quarter, and they can\u2019t afford a part that works fine for a month but tanks once a high-rise in London calls needing repairs. Elevator Parts for BLT<\/a><\/p>\n

<\/p>\n

First off, let\u2019s cut the jargon. A lot of suppliers will throw around terms like \u201cpower factor correction\u201d or \u201cmechanical efficiency ratio\u201d like they\u2019re trying to sell you a rocket ship, but at the end of the day, efficiency for elevator parts isn\u2019t just a number on a spec sheet. For BLT, it boils down to two things: how well the part makes their elevators run, and how little it costs them over its whole life, not just the upfront price tag. I\u2019ve seen way too many parts that are cheap on paper but break every six months, so they end up costing BLT way more in downtime and emergency calls. So today, I\u2019m walking you through the real, day-to-day ways we measure the efficiency of our parts specifically for BLT\u2014stuff we actually use in our warehouse and at their sites, not just lab tests that don\u2019t translate to real-world use.<\/p>\n

Let\u2019s start with the big one for BLT: energy efficiency. BLT\u2019s sustainability team audits their entire fleet every year, and elevator parts are a huge chunk of that. Not long ago, their team noticed that old motor bearings they were using were drawing 12% more power than the industry average, just because they were rough-machined and created extra friction. So when we supply bearings for BLT, we don\u2019t just check the part\u2019s tolerance when it comes off our line\u2014we test it under load, exactly how BLT uses it. Wait, what does that mean? For a 10-person residential elevator in Liverpool, the load is steady most days, like 80% capacity, but for a 50-person commercial elevator in London, the load spikes at 9 a.m. and 5 p.m. We run each part through that exact load profile in our test rig, not just a standard 100% load.<\/p>\n

Last quarter, we did a test run of our planetary gearboxes for BLT\u2019s new mid-rise office fleet. Our initial spec said they were 94% efficient, but we hooked up a power meter during real operation and found they were actually 95.2%\u2014no, that tiny difference isn\u2019t a typo. That extra 1.2% means each gearbox saves BLT about \u00a318 a year in energy, and if they put that in 200 elevators, that\u2019s \u00a33,600 a year. Multiply that over 10 years, and that\u2019s a \u00a336,000 difference. For BLT, energy efficiency isn\u2019t just a box to tick\u2014it\u2019s real cash. We also track standby power, which is the power a part uses when the elevator isn\u2019t moving. Old door operators would draw 15W just standing by, waiting for a call. Our new ones draw 3W\u2014yeah, you read that right. That might not sound like much, but over 12 months, that\u2019s 105kWh saved per door operator, which is like powering a laptop for 12,000 hours. That\u2019s the kind of number BLT\u2019s sustainability team actually cares about.<\/p>\n

Next up, uptime efficiency, which is just as important as energy. Let\u2019s be real\u2014if a part is super energy efficient but breaks every two weeks, it\u2019s not efficient. For BLT, uptime is non-negotiable. A broken elevator in a hospital? That\u2019s a crisis. A broken elevator in a 20-story office? That\u2019s thousands of pounds lost in productivity. So how do we measure the efficiency of our parts when it comes to uptime? We use two things: Mean Time Between Failures (MTBF) and Mean Time to Repair (MTTR). But again, we don\u2019t just use lab numbers\u2014we run parallel tests with BLT\u2019s field teams.<\/p>\n

For example, last year we tested our roller guides against the ones BLT had been using from another supplier. Our initial lab test gave an MTBF of 120,000 cycles, but when we installed them in 15 random BLT elevators across the West Midlands, they hit 132,000 cycles before the first failure. That extra 10% meant BLT only had to replace roller guides once every 5 years instead of every 4. As for MTTR, that\u2019s how fast a tech can swap the part out. We designed our roller guides so they mount with two bolts instead of four, and use a universal adaptor that fits BLT\u2019s existing brackets. That cut repair time from 22 minutes to 8 minutes per unit. For a maintenance crew that handles 10 part swaps a week, that\u2019s 140 extra minutes a week they can spend on other repairs, not waiting for parts or fumbling with weird mounts. That\u2019s efficiency you can actually count on, not just a spec.<\/p>\n

Wait, let\u2019s not forget wear efficiency\u2014this is the stuff that happens over time, not just the first month. A lot of parts look good when they\u2019re new, but start to degrade fast after 6 months, especially in areas with heavy use. For BLT, which has some elevators in places like Manchester\u2019s Piccadilly Plaza that get 1,000+ rides a day, wear is a big deal. We test all our high-wear parts\u2014rollers, brake pads, chains\u2014using a accelerated wear test rig that simulates that 1,000+ ride a day load. We run the parts for 30 days straight, non-stop, and track how much they wear down. If a brake pad wears 0.2mm per 10,000 rides, that\u2019s way better than the 0.5mm BLT was getting before. Last month, we had a BLT tech tell us that our brake pads in a busy Birmingham office lasted 18 months vs. the old ones that only lasted 10. That means less part inventory, fewer emergency call-outs, and less money spent on replacements. That\u2019s the kind of efficiency that builds trust, not just numbers.<\/p>\n

Also, for BLT specifically, we have to account for their existing fleet compatibility. BLT doesn\u2019t want to rip out every old component in their elevators to fit new parts\u2014they need parts that work with what they already have. That\u2019s a huge part of efficiency we don\u2019t talk about enough. Last year, BLT was looking for a new door operator, and one supplier sent us a part that required a whole new control panel. That would\u2019ve cost them \u00a32,000 per elevator to install, plus downtime for two days per unit. Our door operator was designed to work with BLT\u2019s existing control panels\u2014no rewiring, no new software, just plug and play. That saved them thousands in installation costs and cut downtime to 45 minutes per elevator. That\u2019s functional efficiency, and it\u2019s non-negotiable for working with BLT, because they have 3,000+ elevators across the UK, not just a handful of new builds.<\/p>\n

Let\u2019s get real for a second\u2014what are the common mistakes suppliers make when measuring efficiency for BLT? A lot of them just use lab tests without real-world load. I\u2019ve seen a supplier send BLT a part that tested at 96% efficient in a lab, but when installed in a real elevator that stops and starts 20 times an hour, it dropped to 90% because the lab test only ran it at a constant speed. That\u2019s not efficiency\u2014that\u2019s marketing. Another mistake is only measuring upfront cost, not total cost of ownership (TCO). We calculate TCO for every part we send to BLT: energy cost over the part\u2019s life, repair cost, downtime cost, replacement frequency. When we quote our parts, we don\u2019t just give a price per unit\u2014we give a TCO breakdown so BLT can see exactly how much they\u2019ll save over 10 years. Last quarter, that made a huge difference when BLT was choosing between our gearboxes and a cheaper competitor. Their initial quote was \u00a3100 cheaper per unit, but when we ran the TCO, our parts saved them \u00a33,800 per unit over 10 years, because of lower energy use and fewer repairs. That\u2019s how we win business with BLT\u2014we don\u2019t lowball them, we show them the real numbers.<\/p>\n

Another thing we track for BLT is performance consistency. BLT has a brand to uphold\u2014their elevators need to run smooth, no jolts, no squeaks, every single time. We\u2019ve had a few parts in our early days that were efficient on test but had a 10% defect rate when installed, which caused complaints from building managers. Now, we do 100% quality checks for every part that goes to BLT, not just random sampling. We measure vibration levels on every motor we ship\u2014if the vibration is higher than 0.5mm\/s, we send it back, no exceptions. Last month, a batch of 20 motors came off our line with a tiny machining flaw that would\u2019ve made them vibrate too much. We caught it before shipping, which saved BLT from 20 complaints and 20 repair calls. That\u2019s a big part of efficiency too\u2014consistency means less wasted time and money.<\/p>\n

Wait, let\u2019s circle back to what BLT actually needs. They don\u2019t need a parts supplier that can explain efficiency in a PhD-level thesis. They need parts that save them money, keep their elevators running, and don\u2019t cause headaches. When we measure efficiency for our parts, we\u2019re not just checking boxes for our own QA\u2014we\u2019re checking boxes that matter to their bottom line, their uptime goals, and their sustainability targets.<\/p>\n

If you\u2019re at BLT and you\u2019re reading this, or if you\u2019re a procurement or maintenance manager for an elevator company looking to cut costs without sacrificing performance, here\u2019s the thing: efficiency isn\u2019t a number on a spec sheet. It\u2019s the gearbox that saves you \u00a33k over 10 years, the roller guide that only needs replacing every 5 years instead of 4, the door operator that plugs into your existing system and cuts repair time in half. It\u2019s not just about what the part does alone\u2014it\u2019s about how it works for your whole operation.<\/p>\n

<\/p>\n

If you\u2019re part of BLT\u2019s team and you\u2019re looking to tweak your part efficiency metrics, or if you\u2019re ready to test how our parts stack up against what you\u2019re currently using, hit our line\u2014we\u2019re always happy to send over data sheets with real field results, not just lab numbers. We can do a side-by-side test on one of your elevators for 3 months, no strings attached, so you can see exactly how our parts perform in your fleet. No pressure, no fine print, just straight numbers.<\/p>\n

Elevator Parts for TOSHIBA<\/a> At the end of the day, working with BLT isn\u2019t just a business\u2014it\u2019s building parts that keep people moving, whether they\u2019re going up to an office on the 15th floor or down to a hospital\u2019s emergency room. Measuring efficiency isn\u2019t just about making a sale; it\u2019s about making their jobs easier, their elevators more reliable, and their budgets healthier. That\u2019s the standard we\u2019ve stuck to for every part we supply, and it\u2019s why BLT\u2019s been a repeat customer for the last three years.<\/p>\n
