More and more construction companies are adopting RFID to detect safety equipment

More and more construction equipment management companies adopt N4 Systems’ RFID system Field ID to realize automatic document establishment of field work equipment. Elko Wire Rope Mining Supply plans to adopt the N4 Systems solution in June, and Hercules SLR will adopt the new N4 RFID system in February this year.
Elko Wire Rope & Mining Supply provides tools such as steel ropes, rigging and cranes for coal, drilling, and construction companies; the company also provides equipment inspection services, that is, sending professional inspectors to work sites to check the use of equipment. And report to the user. The company also submits the report to relevant judicial agencies, such as the U.S. Occupational Safety and Health Review Board and the U.S. Mine Safety and Health Administration.
Previously, Neely Hammond, manager of the Elko cable factory, said, “We mainly rely on paper records.” The company’s inspectors traveled to mines in Nevada and Utah or other field work sites. They inspected the equipment, wrote down paper reports, and sent them back to Elko’s office. Managers either store documents in file cabinets, enter them into computer systems, or summarize the details in reports and email them to customers.
Hammond said that the paper recording method has the following weaknesses: Paper reports are easy to lose and difficult to trace, and it would take a huge amount of labor to re-enter the information into the computer system. Moreover, customers cannot receive copies of test documents immediately and must store test records to ensure that relevant documents can be quickly obtained when government agencies inspect them.
In addition, the inspector has to spend a lot of time filling out the form. In a dusty environment like this in a mine, it is difficult to check the serial number on the device with the naked eye. If the serial number record is wrong, the inspection record of the device is meaningless.
According to Mondal, after adopting the N4 system, the inspection recording process has been largely automated. Elko inspectors are equipped with two Psion Teklogix Workabout Pro G2 handheld mobile computers with 13.56 MHz RFID readers. Each safety device is affixed with a high-frequency label that complies with the ISO 15693 standard.

Handheld computers can store 8 billion bytes of item-related data, which can be downloaded from the N4 Systems website using Ethernet in the office. Each handheld device stores device data on the workplace, including the serial number in the RFID tag of each item. When the inspector uses the reader to read the serial number of the tag, the handheld device recognizes the type of the device, prompts the staff to check the process for this kind of equipment, and the inspector completes the device inspection according to the prompts.
When the inspector returns to the office, he uploads the data to the N4 Systems Internet server. Customers can immediately see the inspection report through the N4 System software. “We hope this saves a lot of time,” Hammond said.
Hercules uses RFID Psion Teklogix mobile computers to detect up to 1,000 sets of equipment in a week.
