JCB's Hydradig gets a Prolec upgrade

James Fisher Prolec (Prolec) has been working closely with construction machinery specialist, JCB.

Prolec has designed and integrated a bespoke safety system into JCB's new Hydradig excavator which makes it super-safe to operate in confined spaces. The Prolec system ensures the Hydradig excavator complies with tough regulations set by major infrastructure project companies for working in congested environments.

But the specifics of Hydradig’s design and function meant Prolec had to engineer a bespoke solution which would fit the excavator’s compact dimensions but be capable of reliably controlling its range of motion.

Safe working zones

The safety solution Prolec has successfully designed and manufactured is the next generation variant of its flagship ‘rated capacity indicator and machine envelope monitoring system’ which physically limits a machine’s movement. It works by asking operators to define safe working zones on any site. The Prolec system is then able to restrict a machine’s movements should it approach these limits.

This has huge safety implications for Hydradig, allowing the excavator to be used on the new M6 smart motorway conversion (working in the narrow confines of the central reservation without risk to traffic on either side). It also maximises productivity because the movement restriction ensures users can confidently make use of the machine’s full capacity.

Prolec can now offer the new design to Hydradig owners who want to retrofit their excavators for use in confined spaces.

Prolec’s product support manager, Ed Staveley explains:

‘The Prolec system allows the Hydradig operator to manage risk by constantly monitoring the machine’s movement within defined safe zones restricting its movement if it approaches these limits.’

There is a growing requirement for plant machinery to have these kinds of safety systems as standard, and this project for Prolec comes on top of a similarly high profile job for Caterpillar.
