SAFETY CONSIDERATIONS
Most accidents occur within the first five seconds of connecting the attachment to the coupler, and unintentional drops do happen. Coupler-related injuries tend to be the result of an operator failing to secure the safety lock, some of which end in fatality.
the best ways to prevent unintended coupler releases include ample training on installation and testing procedures, increased awareness of the hazards regarding attachment changeout, and ensuring that the pins are inserted and locked properly. The development of hydraulic couplers was a manufacturer response to minimize the risk of injury and fatality, especially as they relate to operator error.
While cost is an important factor in the purchase of any tool, safety should be a top priority when considering how to choose an excavator quick coupler.
HYDRAULIC COUPLERS
Hydraulic couplers offer the highest level of safety and efficiency for your machine and your operators. The attachment changeout process can be completed from inside the cab, with safety features that make them the better choice for preventing injuries on-site.
One of the safety features that has been added to hydraulic couplers include a wedge-locking system that requires the coupler to lock the attachment in two different places. The pressure that this creates will keep both pins and the attachment secure.
Another feature includes a safety knuckle that latches onto the first of the two pins. This eliminates the risk of unintended attachment drop, even if the operator forgets this part of the process. The safety knuckle works separately from the wedge that secures the second pin, meaning that even if the hydraulic system fails, that first pin will not be released. Operators switch attachments by releasing the wedge and securing the attachment on the ground before removing the safety knuckle.
In the event that an operator forgets the attachment is unlocked, some hydraulic couplers have a time-out feature. After about 5-12 seconds, the safety knuckle will re-engage itself if it is not safely removed, preventing an unintended attachment drop. This time frame is customizable to suit operator needs.
DP Quick Coupler changing buckets or special attachments in a few minutes, usually without tools and without leaving the operator’s seat.
