QSC

There are currently around 20 major excavator manufacturers, many of whom supply quick hitch control systems. However, they’re all different and none of them match Engcon’s tiltrotator hitch protocols.

With a direct mount tiltrotator this isn’t a problem but with a twin hitch setup there’s a clear risk of incorrect operation. That’s why we’ve standardised on fitting QSC on all twin-hitch installations using DC2 controls over 6 tonnes.

With Engcon’s Quick hitch Standard Control (QSC) locking system, the hitch control function is standardised, irrespective of the make and model of digger. Whilst specially designed for so-called twin-hitch arrangements (where the tiltrotator is mounted on a hitch that is permanently attached to the excavator), the system works equally well for direct-mounted arrangements.

Ergonomically-designed, QSC has an intuitive sliding cover which immediately identifies the hitch to be operated – either the top (machine) hitch or the lower (tiltrotator) hitch.

In each case, the hitch operation is the same; with the requirement for two buttons to be pressed simultaneously to open, or close, the hitch. The system also uses a boom ram pressure sensor to detect ground pressure, which in turn establishes the requirement for the attachment to be grounded before the hitch can be opened – thus preventing buckets from being accidentally dropped.

Together with the Q-Safe quick hitch, the QSC further increases safety by means of an audio visual alert system. If both bucket axles are not in the correct position, the system uses sound and light alarms. It is also possible to specify boom and slew lock when the hitch is in an unsafe state as an optional extra.

A Q-Safe quick hitch, when combined with QSC and the QLM light module, means Engcon delivers one of the world’s safest quick hitch operating systems. This means the operator always knows what is happening and when it happens.
