Unisafe

Quick hitch

engcon is synonymous with efficiency and safety.
For over 20 years, engcon has worked closely with machine operators and developed safe, dependable and economical attachments for excavators. The close relationship with machine operators, has produced durable and heavily field tested products which meets the markets requirements, as well as european safety standards.The world leading manufacturer has now released its Unisafe double locking coupler series for tiltrotators. This double locking coupler meets the latest safety standards required on the market to date. In conjunction with the engcon Tiltrotator, it offers incomparable efficiency and safety to your machine and workplace. 

The Unisafe double locking coupler eliminates all risk of the bucket falling off by accident, and the engcon Tiltrotator allows the operator to perform more actions without having to move the excavator or even leave the cab.
Fewer movements of the machine not also provides you with a safer alternative – but also a greener and more economical alternative, since pollution is reduced and fuel economy improved.

FAQs

What should I consider when deciding my excavator specification?

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.

How do I safely control locking the bucket and/or tiltrotator? Regardless of the type of excavator I have?

You can do this using QSC – Q-Safe Control – which is a smart panel installed on the right in front of the operator in the cab where the lock buttons for the machine's quick coupler and the tiltrotator's quick coupler lock are brought together in a single control unit. This means the operator, regardless of the type of machine he is using, does not have to search for lock buttons. QSC is suitable for all excavators and every make and type of quick hitch. In other words, engcon has standardized the actual control of all quick hitches thus reducing to a minimum the risk of accidents due to incorrect operation.

Can I use my existing buckets?

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.
