Under the revised elevator inspection standards that will be implemented on September 15, companies and domestic inspection agencies are making quick moves to use weightless inspection equipment for regular elevator inspections.

As part of the plan to advance inspection equipment, the two major inspection organizations are working hard to develop their own weightless inspection equipment before the enforcement date of regular inspections under the revised inspection standards. In particular, Honglim (CEO Kim Deok-young), a specialized supplier of elevator diagnostic equipment, introduced the ELVI system, a weightless inspection equipment developed by Henning in Germany in 2011, to Korea and is waiting for the time of application.

The equipment, which consists of six load testers, acceleration sensors, controllers, and software, is a state-of-the-art upgrade of the currently commercialized ADIA system.

The test equipment can determine the safety force, traction test, brake force, and emergency stop device test by attaching the load testers to the rope without weights and installing acceleration sensors on the upper frame of the car to determine the weight of the car, counterweight, and weight balance. The dual load meter can calculate the braking force and resilience of the restraint by applying equal tension to all ropes. This whole sequence of operations takes place in just 30 minutes.

 

According to Mr. Kim, the fast test time is expected to save costs and eliminate the wear and tear on parts and the hassle of preparing for the test. In particular, it can measure the braking force applied by the gabana under the assumption that the car is free-falling when the rope is cut, making it suitable for safety-critical EN code standards. Currently, the device has been certified in Germany, Austria, Venezuela, and Saudi Arabia and is currently being used in routine inspections, and from September 2013, it will be provisionally permitted in the United States and Canada under Inspection Regulation A17.
