Unimog and Versalift team up for low voltage RT

Versalift hs teamed up with Mercedes-Benz Unimog in the UK to launch a new truck mounted aerial work platform.
The vehicle made its world debut on the Versalift stand at the Vertikal Days exhibition, which took place at Silverstone in the UK this week.
Based on a Unimog U218 implement carrier with nominal 7.5-tonne gross weight, the vechicle is designed to provide utilities companies with a compact, fast and reliable off-road package for work on low voltage power lines in difficult-to-reach areas, at a highly attractive price.
Following the Vertikal Days event, which takes place at Silverstone, the new truck is being made available to operators for trial. Although Versalift has been mounting its equipment on Unimog chassis for many years, this is the first time the two have invested together in a joint demonstration unit.
The Mercedes-Benz Unimog is renowned for its unrivalled combination of on-road speed and all-terrain capability. The new vehicle is fitted with an all-steel boom and platform that offers a maximum working height of 15m. The equipment is insulated to safeguard operatives working on lines carrying up to 1,000 volts – crucially, should the boom make contact, the chassis is also protected. To maintain its Certified LV integrity, the unit requires an annual dielectric test.
Given the demanding conditions in which the Unimog is likely to be employed, Versalift has opted for the sturdy reliability of traditional, fully hydraulic boom operation. However, in the unlikely event that the team using the truck run out of diesel, a clever electronic override ensures the platform can be brought down safely.
Other features of the design include an exceptionally low centre of gravity, enhancing off-road stability, and very little overhang behind the back axle, which makes for excellent departure angles. The Unimog’s panoramic windscreen is also an aid to drivers negotiating rough terrain.
The U218 variant is powered by an advanced and economical 130 kW (177 hp) four-cylinder engine. The truck’s four-wheel drive system provides ultimate traction when the going gets tough while, provided the 7.5-tonne gross weight is not exceeded, it can also be driven under ‘Grandfather Rights’ by anyone who passed their car test before 1 January 1997.
Versalift UK director Andy Bray said, “We do a lot of work with Mercedes-Benz in general, and with its Unimog team specifically, but the joint development of our new demonstrator has elevated the relationship to another level.
“At Versalift we certainly build more complex equipment on Unimogs – the Cat C platform mounted on a 13.5-tonne U530 chassis and delivered recently to Northern Powergrid, for example, is insulated to 46,000 volts and features twin buckets so two operators can work simultaneously, as well as a materials handling jib.
“But the new demonstrator also ticks a lot of boxes as an entry-level, Unimog-based alternative to less flexible machinery such as tracked spider-lift platforms which have to be towed into position. For low-voltage line work, perhaps by arboreal teams clearing foliage, it’s a highly attractive proposition.”
