Leigh, UK, 15.04.2015. Specialist airport and highway maintenance contractor, Allied Infrastructure Management Ltd, has transformed one of its Iveco Daily extruder service vehicles by installing an Allison 1000 Series™ fully automatic transmission. Equipped for the demanding duty of concrete and joint sealing, the switch has resulted in improved efficiency, reliability, ease of operation and confidence in the vehicle delivering maximum uptime.
The 6.5 ton adapted panel van maintains a consistent speed of 2 mph to match the walking pace of the operator who applies sealant to the prepared surface, fed from the van via an extruder arm. In previous stop-start conditions with the original manual transmission, the driver had to constantly engage and disengage the clutch. Upgrading to the Allison fully automatic transmission has negated the issue of clutch wear and fear of potential failure and vehicle downtime due to overheating. Allison’s torque converter increases engine torque and offers uninterrupted power during acceleration and gear shifting, which contributes to making the application of the sealant easier and smoother.
Allied Infrastructure’s runway repair work predominantly takes place overnight between the hours of 12 a.m. and 5 a.m. A workforce of one extruder and five operatives is able to achieve up to 2,000 linear meters of joint sealing in this period; four hours for application and one hour for sealant curing and cleaning-up of the repaired area.
Allied Infrastructure contacted Iveco specialist, Dunstable-based Northern Commercials, which recommended and implemented the Allison Transmission solution, based on other successful installations using the 1000 Series. Notable examples were two fire trucks in the Netherlands and a police van in Switzerland. All three cases were carried out successfully with close support from Iveco.
“The improvement has been significant. Efficiency and reliability have increased markedly,” said Tricia Green, business development and key account manager, Allied Infrastructure UK. “Our operatives find the slow, even and smooth pace required for perfect delivery of the sealant far easier to achieve. This creates a better final outcome in terms of the quality and finish of the joint maintenance. Risk must be managed and minimized when you work in such tight time frames; in an environment such as an airport.”
Green continued, “At 5 a.m. the runways and work areas have to be handed back to Airside Operations and be fit for purpose. The re-gear to an Allison transmission has increased confidence in the reliability of our extruder. We plan to re-gear our other extruders with Allison automatic transmissions in the future.”
