GKN Weels co-develops new solutions for JLG telehandler application

The current offering of Standardwheels has been designed to meet a broad range of off-highway equipment applications. On occasions, OEMs will demand unique solutions to match specific, and often highly challenging, conditions. In such circumstances, the ability for the OEM, tyre and wheel manufacturers to work closely together can provide greater value to the end user. The benefits of this type of collaboration are clearly demonstrated in a design project undertaken by GKN Wheels in North America withaccess equipment specialistJLG

Industries.


JLG was seeking a way to differentiate its products. This resulted in

the development of a solution that provided enhanced telehandler

stability, greater tread life and lower operating costs. Rather than

considering a wheel and tyre design in isolation, it was recognized that

the co-development of the products could maximize overall performance

and offer the best value.


GKN Wheels Armstrong was selected to design and develop the new wheel

due to their engineering expertise and in-house test capabilities.


GKN worked in liaison with the engineers of Bridgestone Americas' Off

Road Division to develop the wheel in parallel with their new tyre, the

Firestone DuraForce MH.


Len Hensel, Technical Director at GKN Wheels, North America, stated:

"The project took into account JLG's requirements, the

characteristics of a newly developed tyre, and the operational and

service elements. From the outset, the approach focused on a close

working relationship between all three companies, rather than each

working in isolation. Instead of selecting standard product as the

basis for development, the solution was engineered from a clean sheet of

paper."


Historically, wheels for this type of application were a 24" or 25"

diameter utilizing 9mm gauge steel. The unique GKN design resulted in a

new 28" diameter size to fit the tyre geometry and has a specific

shape which enables the wheel to support the loading and durability

requirements of the machine, while using a lighter 8mm gauge steel.


In addition, the 28" rim shape offers improved tyre serviceability

relative to conventional wheels, despite the stiffer tyre sidewall,

resulting in reduced servicing costs.


The wheel and tyre combination provides superior customer value from

the enhanced tread wear characteristics that result in a projected tyre

life that is up to three times more than the Firestone SGG. The new

designs have also allowed JLG to reduce from four tyre options down to

two. This means fewer parts to stock and reduced inventory-carrying

costs for JLG distribution.


Commenting on the development, Michael Poirier, General Manager of

Corporate Accounts for Bridgestone Americas' Off Road Division said:

"We are extremely proud to have collaborated with JLG and GKN to

bring one of the most exciting introductions to materials handlers in

many years. We utilized the collective strengths of three organisations

to deliver a superior product that dramatically improves the total cost

of ownership and the overall stability of the machine."
