Regular cleaning of the hoistway to remove construction dust and debris is the most effective preventative measure against physical belt scratching.
If a scratch is deep enough to expose the internal steel wires or cords, the belt is compromised and must be replaced.
Combined with ReGen drives , which capture energy normally lost as heat and feed it back into the building’s grid, the system is up to 75% more efficient than conventional elevators.
The Gen2 door systems, whether center-opening or telescoping, rely on precise tracks and hangers. If door hangers are loose or the tracks are misaligned, the metal door panels can swing slightly. As they open and close, the edge of one door panel can scratch the face of the other panel. otis gen2 scratch
By far, the most effective solution to scratching noises is preventing them through a proactive maintenance program. Otis emphasizes that many problems are entirely avoidable when preventive maintenance is up-to-date.
The belts should only be cleaned with mild soap and water when they become excessively dirty. Aggressive chemicals must be avoided. The guide rails require specialized rail oil applied at the correct viscosity to prevent scoring without over-lubricating and dripping onto the belts.
The occurrence of a scratch or scratching noise on an Otis Gen2 belt can usually be traced back to a few specific mechanical or environmental variables. 1. Foreign Debris and Contamination Regular cleaning of the hoistway to remove construction
Specifically, the sound occurs when the steel tension members inside the flat belt move unevenly against the polyurethane coating, or when the belt’s surface wears unevenly against the machined grooves of the traction sheave. Over time, these components fail to mesh smoothly, generating a rhythmic, cyclical scratch coinciding with the rotation of the drive sheave.
Its compact machine and controller can fit inside the hoistway, eliminating the need for a separate machine room.
The is more than an acoustic nuisance; it is a diagnostic signal. It tells you that the friction balance between belt and sheave has failed. Whether caused by dust, misalignment, or worn polyurethane, every scratch is a countdown to a more expensive failure. By far, the most effective solution to scratching
Excessively tightened bolts can cause belts to "pucker," leading to uneven and premature wear.
This refers to superficial or deep scoring, scratching, or gouging along the length of the flat belt.
Modernize your maintenance mindset, and your Otis Gen2 will reward you with decades of silent, reliable vertical transportation.
