Compatible with your
QLM – Q-Safe Light Module is a system used in combination with Q-Safe to provide both a visual and audible warning unless both bucket axles are in their correct positions and locked.
QLM is provided as standard when the Q-Safe quick hitch is selected together with the engcon tiltrotator.
QLM is ordered as a separate product for Q-Safe quick hitches for excavators (machine hitch).
The QLM module is installed on the left side of the excavator's arm and its cabling is integrated into the DC2 cabling.
If a control system other than the DC2 is used, run a separate cable for the QLM to the excavator cab.
Order the full system with slew limitation and ground contact for releasing tools in consultation with the machine supplier concerned.
engcon will successively provide Q-Safe™ as the standard quick hitch lock in the sizes S45, S50, S60 and S70. This applies to both the machine hitch and the hitch under the engcon tiltrotator.
What is most important for you?
System engcon, centred around the tiltrotator, saves both time and fuel.
Fewer machine transits and less need for manual work increases safety at the workplace.
The tiltrotator's ability to tilt and rotate makes the machine a good all-rounder that carries out most tasks with greater precision.
Fewer machine movements and faster jobs mean less wear on the machine.
Despite the increasing popularity of tiltrotators, many excavator manufacturers do not yet sell 'tiltrotator-ready' machines on certain markets. There are two main considerations when buying a new excavator for use with a tiltrotator - dipper length and hydraulics. Ideally, a shorter dipper should be chosen to take into account the build height of the tiltrotator. For example, if the standard dipper length is 2500mm, choose one 2000mm long so that the extra reach resulting from the addition of the tiltrotator still falls within the manufacturer's safe working range and that there is no chance of the bucket or other attachment hitting the cab when fully crowded.
The standard machine hydraulics can often be used for tiltrotator operation, but the machine controls may not be sufficiently sophisticated to fully exploit the capabilities of the attachment. Tiltrotators are usually supplied with so-called fully proportional control systems. These allow the hydraulic power to be gradually increased according to the needs of the attachment and the task to be completed, for example when pouring type 1 or concrete into a narrow area or using grabs or pallet forks. Non-proportional, or on/off systems which are generally button-operated do not allow the delicacy of control necessary for many tiltrotator operations.
If the excavator has two dual-acting proportionally controlled hydraulic circuits, then basic tiltrotator operation should be possible using the excavator's controls. A third, non-proportional circuit will be required for the tiltrotator hitch. Where a single, dual acting circuit is fitted, it is often more cost-effective to use engcon's DC2 control system which manages the hydraulic switching and flow proportionally within the tiltrotator, rather than have additional circuits fitted.
The pin geometry on your existing buckets is unlikely to be compatible with the S-type coupler fitted to standard tiltrotators. Choosing a Unisafe/PUP coupler to allow you to use your existing buckets is likely to be a false economy for the simple reason that tiltrotator (s-type) buckets are designed for tiltrotator digging. Not only is the angle of the bucket optimised for tiltrotator use, but the bucket geometry (shape, size, etc.) is specific for rotational and angled digging and grading. The saving you make by choosing the S-type coupler can be re-invested in top bracket adapters to convert your existing buckets and other attachments.
If you are running hydraulic tools, you can also purchase adapter brackets EC-Oil ready, or pre-fitted with EC-Oil and thus convert your current hydraulic tools with ease for the S-type coupler.
