Bell Equipment has supplied UK contractor
John F Hunt with three 25 tonne B25E
articulated dump trucks (ADTs) for land
remediation work on amajor contract
recently won by the latter company. They
join two D-Series ADTs that have been
in the contractor’s fleet for the last nine
years.
John Yeldham, depot manager at John
F Hunt, explained: “The Bell dump trucks
are reliable and hardworking and we’ve
experienced very little downtime. On the
rare occasions we’ve needed help, Bell has
provided a great back-up service. The Bell
B25E is the ideal size for our purposes
and we’re getting the excellent results we
anticipated.”
The new generation E-series offers
increased production payloads, lower daily
operating costs and superior ride quality,
with Bell claiming the lowest fuel cost per
tonne on themarket for itsmachines.
The smallest in the Bell ADT range, the
B25E reflects the importance of having a
high-quality, robust dump truck capable of
working within the often confined spaces
resulting from a demolition.
“It is, in part, for applications such
as these that we supply a 25-ton ADT,
so we’re delighted that John F Hunt
has recognised the advantages of
choosing a smaller machine capable of
exceeding expectations in tight working
environments,” confirmed Richard Higgott,
sales andmarketingmanager at Bell
Equipment UK.
