1.    Introduction of TCK-DT Series Elevator Wire Rope Testers

Wire rope is an 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 instruments, wire rope safety has always been a “blind spot” of elevator safety management and even the “hidden danger” for passengers’ life.

TCK elevator wire rope tester adopts the world’s leading and proven weak magnetism inspection technology. It is capable to inspect multiple ropes at the same time, and solve effectively the problems concerning elevator wire rope inspection. It 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 conclusion regarding the safety status of the inspected wire ropes.

TCK 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 worldwide.
