Why is the Q-Safe one of the world’s safest quick hitch locks?

Q-Safe cannot be opened with the tool off the ground. The bucket must be in contact with the ground in order to disconnect* it. In other words, it's impossible to drop the bucket through unintentional opening of the quick coupler lock.

Furthermore, Q-Safe enjoys threefold safety through:

1. Monitoring functions with audio and visual alerts to warn the operator if the bucket is not correctly connected.
2. Powerful springs and hose burst valves in the locking cylinders maintain the lock function in the event of a ruptured hose. This unique design feature makes it impossible for the bucket to dislodge, even if the locking cylinder or other hydraulics should fail.
3. Preventing full excavator use, unless the bucket or tool is properly connected, by activating slew limitation* or boom lift limitation*.
