No more need for on-site employees risking unstable movements on a steel structure while trying to unhook the crane’s slings. The remote controlled sling release ensures maximum security while allowing the crane operator to unhook by remote control therefore, eliminating all-risks of falling and injury. Since 2009, the use of DLR is strongly recommended  for jobs on crane operated sites.


User-friendly, the DLR allows contractors to save time on every haul. Manually detaching the sling can take several minutes. By the end of the day, these minutes turn into hours. The remote controlled sling release can help you save precious and costly time.


Thanks to the DLR’s speed and simplicity, contractors automatically increase cost- effectiveness. Investing in a DLR is indisputably a short, medium and long term profit. An innovative, wise and lasting choice.

About us


In 2007, Benoit Rouleau, inventor of the DLR, got the idea to create this device as the CSST Commission increasingly continued to oppose, with reason, dangerous work methods practiced by structural steel workers. Mr. Rouleau then thought of an electronic release remote control that could replace manual labour and at the same time provide a safer work place.

Mr. Rouleau worked non stop nights and week-ends. After a full year of research and 4 prototypes later, the DLR was unveiled. Even though the DLR is completed and highly reliable, Mr. Rouleau continues to improve the DLR’s performance as well as customer satisfaction.
