I. Overview of URNDT Elevator Wire Rope Testers
Wire rope is a very important, but high-risk component of elevator equipment as it directly concerns the safety of passenger life and property. For a long time, due to the lack of reliable inspection equipment, wire rope safety has always been a “blind spot” of elevator safety management and even the “hidden danger” for passengers’ life.
URNDT elevator wire rope tester adopts the world’s leading and proven weak magnetism inspection technology. It is able to inspect multiple ropes at the same time, and solve effectively the problems concerning elevator rope inspection. This equipment could detect quantitatively all types of flaws such as broken wires, corrosion, abrasion and fatigue of multiple ropes simultaneously. The testing data is presented in a detailed and easy to understand numerical report, with clear conclusions regarding the safety status of the inspected wire ropes.
URNDT Elevator Wire Rope Tester has achieved the perfect combination of innovative technology, practicability and miniaturization. With a PC, testing data is displayed in real time and the testing result is not affected by the speed and load of the target elevator. It is easy to operate and has been recognized by users as the most advanced NDT equipment for elevator wire rope inspection in the world.

IX. Applications of Elevator Wire Rope Tester
URNDT Elevator Wire Rope Testers have been accepted by elevator manufacturers and elevator maintenance companies and used to inspect wire ropes of both passenger and freight elevators.
Elevator manufacturers like Nippon Otis have entered partnership with URNDT to develop customized rope testers for inspecting their elevators worldwide.
To ensure the safe and reliable operation of elevators in Beijing during the 2008 Olympic Games, Beijing Bureau of Quality and Technical Supervision held a public bidding for 12 elevator rope testers. With its leading and proven technology, and quality customer services, URNDT won the bidding. During the Games, all critical elevators were tested with URNDT rope testers, which made significant contribution to the safety of the Games.
