Engcon will no longer offer the older, industry-standard S-type quick hitches in the sizes S45-S80, which date all the way back to the 1980s. The new Q-Safe (QS) quick hitches, which are backward-compatible with the Scandinavian ‘S’ geometry, will still pick up attachments using this standard but crucially will connect hydraulic and electrical power automatically from an excavator to its tools and attachments using EC-Oil and, because of the intelligent nature of the hitch and control system, are counted among the world's safest hitches.

Engcon's QS quick hitches and QSC locking system eliminates the potential of human error that can occur when attaching or detaching buckets and other tools and attachments. Because the bucket’s axles are independently detected by electronic sensors, swinging or half-connected buckets are not possible. Ground-pressure sensing further eliminates the possibility of operator error by requiring the attachment to be grounded before the hitch can be opened and it is also possible to disable the digger’s boom and slew functions when the hitch is in an unsafe state. As well as preventing operator error or misuse, the system also has boom-mounted audible and visible alarm to warn nearby operatives when attachments are being changed or the hitch is in an unsafe state.

The growth in the use of hydraulic attachments on job sites has led the company to make its EC-oil automatic hydraulic connection system a standard fitting on installations using the DC2 control system. This means that operators using the company’s tiltrotators on diggers from 6 tonnes upwards can change hydraulic tools without having to leave the cab.
