engcon Q-safe & EC-Oil English

engcon's Q-Safe™ is the one of the safest quick hitch locks on the market, where the risk of incorrect coupling is designed out. With Q-Safe™ fitted to an excavator, the bucket or tool must have ground contact that exerts a given pressure. In other words, buckets, tools and attachments cannot be
removed whilst in the air.

1 When the Q-Safe™ quick hitch lock makes contact with the bucket or attachment's first axle, the area around the machine is warned by sharp audible and visual signals, and the machine's turn function is blocked.

2 As long as the bucket or attachment is not properly locked on both axles, the audible and visual warnings will continue.

3 When both axles have full contact, the audible/visible warnings are cancelled and the turning block is released. The machine is ready to work with the bucket/attachment fully connected.

The Q-Safe™ hydraulic quick hitch lock features safety functions such as:
a. electronic surveillance via two independent sensors that monitor both axles' contact.
b. a non-return valve prevents the hydraulic cylinder opening even in the event of a hose rupture/pressure drop.
c. powerful, exterior springs keep the hitch locked even if the electronics and hydraulics fail.
d. in addition, the rear axle is locked in a wedge-shaped position with a smart "steel-lip" preventing the attachment falling out of position regardless of anything failing in any of the other safety functions.
