Customizing Plant

Utility Service CompanyCustomizing Plant
to Increase Safety
is a Priority for
Utility Service Company

Morrison Utility Services (MUS) has added a further 60 Volvo EC18Ds and 3 ECR50Ds to its mobile plant fleet, all of which have been fitted with unique safety features to prevent the inadvertent operation of controls, thus significantly cutting out large elements of risk.

Already a significant user of Volvo utility equipment MUS has been adding EC17s and EC18s to its mobile plant fleet since 2000 and, in the process, has developed a strong relationship with Leeds based Chippindale Plant - Volvo’s utility dealer covering Yorkshire and the north east of England.
This latest batch of sixty Volvo EC18Ds and three ECR50Ds has been equipped with unique, factory fitted safety features to satisfy MUS’ requirements.

Our aim is always to significantly reduce and preferably eliminate elements of risk in all areas of our operations,

explains Jeremy Harrison, MUS Director of Plant and Fleet Services.

One major area of concern is the inadvertent operation of machine controls by our operatives working on site. This could be the accidental use of machine controls such as clothing brushing against servo levers or even a deliberate shortcut. We therefore challenged Chippindale Plant and Volvo Construction Equipment to devise a system that eliminated these scenarios,

he continued.

Morrison Utility Services have their own special trailer to transport mini-excavators from site to site.

With this remit in mind Volvo’s compact excavator design engineers came up with a unique solution which has been fitted to all of the latest 63 machines.

Morrison Utility Services have their own special trailer to transport mini-excavators from site to site.

The net result is a system whereby the operator must be seated and, having lowered the left hand control console (which normally activates the hydraulic system), must then activate a separate switch on the dashboard to make the system live.

Each time an operative lifts the left hand console or leaves the seat, the switch must be depressed again to re-activate the system. It means, for example, if the operator stands up to look into the trench being dug, an accidental, uncontrolled movement of the machine cannot occur when the operative sits back down.

An additional requirement was to facilitate the safe use of hydraulically operated hand-held tools. All sixty EC18Ds have been fitted with additional service lines and a similar unique safety feature requiring a second switch on the dash board to be depressed to activate the hydraulics.

Once depressed this isolates all other hydraulic functions of the machine. Aside from the hand held tool operation, no other accidental or unauthorised use of the machine can therefore take place. Conversely, once the machine is being operated in the normal way, the hand held tool line is isolated.
