BLT lifts

Service life is determined not by the country but by what is inside: the traction machine, controller, guide rails and doors. In its basic specification, a BLT lift performs well in a residential building with average traffic. For a building with heavy traffic, we re-specify the drive and controller with European components, and then the discussion of service life becomes concrete, with specific items in the specification.

Yes, this is done for a specific order. The components most often upgraded are the traction machine, the variable frequency drive (VFD) and the controller, the parts whose failure costs the most. The extra cost is noticeable, so the decision is made per project: for a five-storey residential block it usually does not pay off, but for a business centre with a morning peak it does.

Buttons, sensors, door rollers and brake linings are cheaper to include as a kit in the original order, while the container is shipping with the lift anyway. After that, some items can be sourced from what is available on the market. The worst-case scenario is waiting for a small part sent separately from halfway around the world, and that is exactly what we try to avoid.

A sea route with transhipments plus customs clearance versus a truck overland from Europe: the difference in lead time is significant. The factory gives an exact date once the order is confirmed. We do not quote a lead time in advance: it depends on how busy the production line is and on the freight situation, and a promise made at random hits the construction schedule.

Yes, we both install them and take them on for maintenance in Ivano-Frankivsk, Lviv, Ternopil, Chernivtsi and Uzhhorod. A practical point: the factory drawings must be checked against the actual shaft before the order is confirmed. Correcting dimensions once production has started is slow and expensive, so we go out and measure ourselves rather than relying on the designer's figures.
