No more need for a third hand
The Hook Latch Trigger was conceived in response to a real challenge. It’s one example of how internal R&D collaboration and close cooperation with customers can result in innovations that help improve productivity, ergonomics and safety.
Employees of Konecranes’ service branch in Tasmania noticed that at customers’ sites, safety latches on crane hooks were often deliberately broken or taped open to facilitate easier operation when putting chains in or taking them out. This practice is highly unsafe and is prohibited for many reasons.
Without a properly functioning safety latch there is a risk of the load falling during the lifting process. Also, the safety latches on large hooks are quite strong, posing a risk of hand injury while loads are being attached.
Aiming to provide a solution, local Konecranes service personnel built a hook with a handle that the user could push down to get the safety latch open without having to put their fingers in the hook’s opening. While the solution wasn’t technically optimal, it raised attention about an existing need and sparked further development.
Continuous development and testing
Konecranes’ R&D function got hold of the concept for the Hook Latch Trigger through the company’s global innovation work. Since then, employees from Finland and India have joined in and developed several iterations. Each phase has brought new technical features and responded to new needs.
