POTENSI exhibits lift and escalator parts at Lift Expo Moscow 2026, 10–12 November. Crocus Expo, Pavilion 3, Hall 13, Booth A5. Bring a part, get a straight answer.

Yes, most lift doors have a sensor — but not all, and not the same type. How to tell what your door has in three checks, and what the sensor still cannot cover.

What an elevator ARD is, how the automatic rescue device works, what 220V and 380V models mean, how to size one for your lift, and what drives the price.

Most explanations of how an elevator traction machine works say the same thing: the motor turns a wheel, the wheel moves the ropes, the car goes up. That is true, but it skips the part that actually explains the machine.

A traction machine does not wind the ropes onto a drum. It grips them.

Elevator door sensor types fall into five groups: infrared light curtains, photo eyes, mechanical safety edges, ultrasonic sensors, and 3D sensors. This guide covers each type, how to identify the one you already have, and which to choose.

Escalator handrail replacement may be necessary for deep cracks, exposed reinforcement, permanent deformation, or serious joint damage. Dirt, minor surface marks, poor tracking, and speed differences do not always require a new belt. A qualified technician should first inspect the handrail and related components.

Learn how to choose the right escalator handrail by material, profile, dimensions, length, joint type, application, and supplier support.

Learn what elevator buttons are, how they work, common types, materials, COP and LOP applications, selection tips, replacement advice, and FAQs for elevator projects.

Public places like metro stations, airports, and shopping malls require highly reliable equipment. To ensure passenger safety and reduce risks, choosing the right escalator safety devices is essential. This article explains the key components needed to meet international standards and maintain safe operations in busy environments.
