System Introduction

As a high-risk and key component of cableway equipment, wire rope is regarded as the “lifeline” for the cableway transportation. However, for a long time the rope failure accidents always lurk during the operation of wire ropes due to the lack of scientific and reliable inspection instrumentation. Management departments mostly adopt the methods of visual inspection and periodic replacement of wire ropes to ensure the safety of in-service wire ropes .

However Visual inspection only detects external flaws, but cannot detect “major hidden dangers” such as internal broken wires, abrasion, corrosion, fatigue and so on. Periodic replacement of wire ropes results in huge waste which cannot radically prevent wire rope failure accidents.

Traditional wire rope inspection technology cannot accurately detect the flaws of wire ropes due to its various limitations such as low sensitivity, low repetition rate, influence by speed, “zero drift” and big weight. Therefore the safety of in-service wire ropes has always been the “blind spot” in cableway safety management.

TCK•W® Weak magnetism inspection technology successfully solves the difficult problems in the safety inspection of cableway wire rope and provides cableway management departments with reliable method to monitor the safety status of wire ropes, avoid rope failure accidents, scientifically reduce the cost of wire rope replacement and enhance the service efficiency of wire ropes.

① TCK•W® Modular Inspection Device

-Real-time monitoring wire rope safety status while wire rope is running at high speed;

-The operation of wire rope is always at a safe and controlled monitoring status;

-Weak Magnetic Sensor with high sensitivity, high stability characteristic, not influenced by the operation speed;

-Wide-spacing and non-contact inspection to ensure safety operation of the inspection device;

-On-line positioning installation and automatic operation;

-Suitable for all-weather indoor and outdoor working environments, with rain-proof, shock-proof, and oil-proof design。

② TCK•W® Intelligent data collection & conversion workstation

-Intelligent multi-channel two-way automatic information communication mode;

-Modular multi-function unit combination, easy for updating;

-Shield-type information receiving & conversion and anti-interference design。

③TCK•W® Photoelectrical Distance/Speed Measuring Device

-Adopt high-precision photoelectrical encoder and light aluminum frame;

-Anti-loosening mechanical structure, self-clamp-floating cantilever support, and friction wheel with multi-channel anti-slip rings;
