Manufactured Elevator Quality

Three Towers

by Russ Ward – It makes me chuckle when I hear people say there are several elevator manufactures. In reality, there are precious few that actually engage in manufacturing. The definition of manufacturing is the making of goods or wares by manual labor or by machinery, especially on a large scale. The rub is that the big four elevator companies do not make goods or wares.

Instead, what they actually do is produce some elevator parts. The rest of the parts are produced by subcontractors that supply several companies. When an order is placed and the elevator leaves the warehouse, it is not recognizable as an elevator at all, but several components that then need to be screwed, wired, bolted, hung and placed inside a pre-existing or stick-built vertical shaft.  The real elevator manufacturing takes place inside the vertical stick-built elevator shaft on the job site. Until it is assembled, it is not a ware or a good but a box full of parts.

It would be the same if you ordered a car from your local dealership and were handed the keys and a giant crate full of parts. Find out why manufacturing is the best way to make an elevator. Click here.

Footprints on the Ceiling

142ofc_copyI remember a Classics Illustrated comic book from my youth telling the tales of Abraham Lincoln. One of the stories involved Lincoln gathering a group of younger boys and having them step in the mud with their bare feet. As a prank, Lincoln held each of them upside down and had them walk their feet across the kitchen ceiling, leaving muddy footprints as they went. When his stepmother, Sarah Lincoln, came home and saw the muddy footprints on her ceiling, she threatened to spank him.

Lincoln was 6 feet 4 inches tall at the time, and I can all but imagine seeing the future President bent over his stepmother’s knee, stovepipe hat and all. Also, his stepmother’s initial reaction to the unnatural site of footprints on her ceiling would have been priceless.

Sometimes when our elevators are craned vertically into place and the inspector or elevator technician is in the hoistway for the first time, they, too, have a reaction like Sarah Lincoln. They see footprints going up and down the hoistway walls, along guide rails and around hatchway door openings. Some have even asked our installation crew where the footprints came from and how they could be up and down the vertical hoistway. And no, we don’t hold people upside down.

That is one of the challenges we face when describing the Phoenix Modular Elevator process of manufacturing. In the mind of most elevator professionals, they think vertically when they enter a hoistway or elevator car. It only makes sense, as they have spent years, if not decades, inside a vertical shaft.  For them, it is hard to think of it any other way.

However, our elevator manufacturing process is born horizontally. The hoistway is not built on a work site, but out of tough 4×4 inch tube steel in our production facility. Once the frame is laid out, it is plumbed and squared to make sure the shaft is always perfectly square and straight. Phoenix Modular Elevator workers and inspectors are able to walk alongside the frame, inside and out, testing welds and checking quality. As the frame is constructed, it is placed on a machine that can literally spin the hoistway, so welding in 2×4 C-studs and placing fire-rated drywall takes hours, not weeks. When one side is done, the entire hoistway is rotated to the next side. The guide rails are then installed, leveled and inspected. We know when a hoistway leaves the factory, it is completely square and the guide rails are straight and level.

During this whole process, a great crew of quality inspectors, welders, drywallers and finishers stroll through the hoistway, leaving footprints. Mystery solved.

Simultaneously, the cab is completed to the customer’s specifications. Again, the cab is not inside the shaft; instead, it is built in a separate area of the factory and not in a cramped hoistway. This means building the car is safer, easier and faster. When the car and hoistway are complete, we simply insert the cab in the still-horizontal hoistway. All connections are made, the car and counterweights are roped if needed, and it is ready to be transported by truck to the work site.

So the magician has shown his trick. How did the footprints get up and down the hoistway walls? The hoistway is never vertical until it gets to the site where it is installed faster and easier than a site-built elevator.

Hotels + Modular = The Perfect Solution

Red Roof InnHotels built prior to the Americans with Disabilities Act (ADA) have a decided disadvantage when meeting the needs of potential customers. With only stairs to transport guests to upper floors, people with some disabilities have limited choice of the rooms they can occupy. It also means that people who do not want to carry luggage up a flight of stairs may seek other accommodations.

This issue  will likely grow. With the graying of America, the number of disabled persons will continue to increase from the 57 million current reported by the US Census Bureau. That is a whole lot of people that a hotel without an elevator may not be serving well, or at all.

Since the passage of the ADA in 1990, it has become an expectation that access will be provided. However, many older hotels are not accessible beyond the first floor, and although it is perfectly legal for older hotels to be grandfathered in and avoid ADA requirements, it may not make for the best customer experience. This can also lead to a lower rate per room for higher floors. To combat this problem, one hotelier was able to meet his patrons needs by placing a modular elevator on the exterior of the existing structure.

An ancillary benefit of the modular elevator addition is that employees were no longer lugging heavy laundry carts and other items up and down stairs. The elevator increased staff productivity and morale while also reducing the potential for work-related accidents and injuries. It was a win for the hotel, not only because it opened new possibilities for customer and employees, but because the installation was easy and fast.

For a commercial-quality modular solution, another benefit is time. A hotel does not have to close its doors for an extended period of time during installation, as a modular elevator is lowered into place by a crane in under half a day, and installation can be completed in a week.

The end result is a more profitable, safer hotel that provided access to more potential customers and a way for workers to be more efficient and productive.
