Truck and Track



Haulage halves its NOx

output in five years

Harmful NOx emissions from trucks have halved in only five

years, according to new government statistics.

Department for Transport figures show a 52 percent fall between

2013 and 2018 as haulage firms have upgraded to cleaner Euro VI


The Road Haulage Association says that the trend is set to continue

and projects that NOx emissions from HGVs will have reduced by

more than 80 percent by the end of 2025.

But the Association, in its NOx Emission Assessment, warns that

many operators face an uncertain future as local authorities press

on with plans which will see hauliers charged up to £100 per day to

enter clean air zones.

RHA chief executive, Richard Burnett says that efforts to improve

air quality will fall short until they proportionately target sources

of emissions.

“The government is signing off poorly conceived measures which

punish hauliers for local authority failures to keep emissions in

check,” he said.

“But we’re leading the way – we’ve more than halved our NOx

emissions in the last five years and this will only continue as firms

upgrade their fleets.”

Lorries and buses account for a small, declining proportion of NOx

emissions according to National Atmospheric Emissions Inventory

data. Figures from2015 show that the sectors were responsible for

only 7.6 percent of NOx, whilst the share from other key sources

such as ‘passenger cars’ and ‘combustion in industry’ were much


Latest FlexiEdge fast-action doors

Stertil Door Products is attracting unprecedented interest

and orders for its latest generation of FlexiEdge fast-action

doors. Originally introduced to the UK market in 2013, the new

FlexiEdge models continue to provide exceptional safety plus

unrivalled resistance to wind, weather and impact damage.

The latest FlexiEdge models comprise 16 models of different types

and styles including internal and external doors, all-weather

doors, cleanroom and freezer/coldroom doors plus emergency

exit doors incorporating breakthrough curtains. Standard models

are available in widths up to 11 metres and heights of 5.5 metres

whilst bespoke and special sizes may be specified.

Featuring revolutionary design, the new FlexiEdge doors are

manufactured fromtopqualitymaterials including galvanised steel

for structural strength allied to reinforced polyethylene side guides.

The door curtains, whichhave beendeveloped tooffer flexibility and

durability, incorporate no rigid elements. A hi-tech manufacturing

process involves the insertion of reinforced polyester within a

PVC sandwich to produce a high strength yet lightweight door

curtain. These curtains are available in a wide range of standard

RAL colours and various style options that include vision panels

and windows, translucent curtains, insulated versions for chiller/

freezer applications and fly screen curtains. Many of thesemay also

be specified to incorporate company names, logos and other types

of corporate branding.

FlexiEdge fast-action doors have been designed to set new

standards of safety. The door curtain is fully flexible with a soft

bottom edge which not only self-adjusts to seal on an uneven floor

but also avoids any possibility of causing injury to users. In addition,

the incorporation of an infra-red photocell, fitted 300mm above

floor level, supported by a bottom edge wireless detector ensures

instant halting of all door movement in the event of sensing an

obstruction of any kind. Also, the flexible soft-edge curtain provides

maximum resistance to damage caused by a vehicle collision. If the

door edges are knocked out by the collision, they are automatically

re-inserted in the side guides as the door opens.

A wide range of activation systems allows maximum versatility

of FlexiEdge doors in many different applications. Alternatives to

the standard push button pads include wired and wireless pull

cords, key switches, induction loops, photocells, radar, radio or

infra-red transmitters, presence detectors and touchless hand-

wave detectors. Depending on the requirements of individual

applications, the most appropriate activation method may be

specified to ensure that the doors may be used intensively in the

busiest high traffic areas.
