Q-Safe™ is engcon's newly-developed quick hitch lock for excavators. The biggest innovation is that incorrect tool connection due to the 'human factor' is no longer possible. The system simply takes over some of the operator's safety duties.
Q-Safe™ has threefold safety and forms part of engcon's 'Non Accident Generation' initiative in which safety awareness hallmarks the whole product range.
With Q-Safe™, engcon has constructed one of the world’s safest quick hitch locks, where the risk of incorrect tool connection is designed out. With Q-Safe™ fitted to an excavator, the bucket or tool must achieve a certain ground contact pressure to allow connection or removal. It is simply not possible to release the bucket or tool while it is hanging in mid air.
When the Q-Safe™ quick hitch makes contact with the bucket or tool's first pin, people in the surrounding area are alerted by a loud audible warning and bright warning light and the machine's slew function is blocked.
The audible warning and the light will continue to alert all the time the bucket or tool is not properly locked by both pins. Furthermore, the slew function will continue to be blocked.
When both pins have full contact, the audible/visual alerts are cancelled and the slew restriction released. The machine is ready to work with the bucket/attachment fully connected. The tool can now only be removed when it is resting on the ground at a given pressure.
* The ground pressure function requires the bucket/tool to exert pressure on the ground before it can be unhitched. The function comes with the engcon Quick coupler Standard Control (QSC) locking system.
Electronic monitoring, hydraulic locking and a mechanical blocking function. With Q-Safe™, the safety system shoulders some of the operator's responsibility for connecting the attachment correctly, thus providing a safer workplace. Initially, Q-Safe™ will be delivered with a warning system. Order the complete system with slew limitation and the ground contact requirement for tool disconnection in consultation with the machine supplier.
From 2014, in a phased program, engcon will be supplying Q-Safe™ as a standard quick hitch lock in sizes S45, S50, S60, and S70. This is applicable both as a machine hitch and below engcon tiltrotators
