Elevator  Wire Rope  Intelligent Safety Monitoring Device

Product Introduction

For long-period service in tensile fatigue and bending fatigue, wire ropes will be easily affected by flaws of broken wires, abrasion, corrosion, fatigue, etc. To some certain severity, one of service wire ropes will be broken first and the rest will be broken one by one in a short time caused by load accumulation. When the load is over limit, the rest wire ropes will collapse instantly, which may lead to serious accident of cabin falling and personal death or injure.

Although elevator “Safety Gear” could provide secondary protection against cabin falling accident caused by sudden wire rope failure, blood lessons from most accidents of serious casualties prove that applying “Safety Gear” is not absolutely safe.

TCK•W® -DTAJ elevator wire rope safety intelligent monitor equipment, adopting the most advanced Weak Magnetism Inspection Technology in the world , 24-hour online intelligently monitors the safety of service wire ropes and alarms timely for sudden rope breakage and serious flaws that affect wire rope safety.

The application of TCK•W®-DTAJ elevator wire rope safety intelligent monitor equipment, not only can ensure elevator wire ropes operation safety, but also can effectively reduce visual inspection workload, improve inspection efficiency and save inspection time. It will be the “Protector” for elevator wire rope safety.
