Uttoxeter's biggest employer has secured one of its biggest orders in the UK – and is set to net more than £55 million as part of the deal.
JCB will receive the huge fee in exchange for more than 1,200 machines and a range of generators.
A-Plant, described by JCB as "the country’s leading equipment rental company", has placed the huge order.
It includes more than 600 JCB Loadall telescopic handlers and more than 450 mini and midi excavators.
Other machines included are rough terrain forklift trucks, site dumpers, backhoe loaders and tracked excavators.
The deal is good news for JCB’s factories in Rocester, Uttoxeter, Cheadle and Hixon, whose products have been purchased in the landmark order.
The volume of generators bought is enough to power eight hospitals or 4,000 homes.
JCB UK and Ireland sales director Dan Thompstone said: “A-Plant has been buying JCB equipment now for more than 25 years and we are delighted to support its latest investment in our equipment.
"We are proud of our long-standing partnership with A-Plant, delivering innovative, quality products supported by excellent parts and service back-up from Greenshields JCB.”
JCB employs around 5,400 workers at its factories around Staffordshire.
The company revealed late month at its earnings grew to £287 million in 2016, up from £214 million on the previous year. That came on the back of sales increasing to £2.62 billion from £2.34 billion over the same period.
In total, the manufacturer sold 66,011 machines compared to 59,844 in 2015.
The performance was achieved despite a contraction in the global construction equipment market of one per cent.
A Staffordshire Chamber of Trade spokesman said: "As well as being a world-leader and a household name, JCB is a fantastic advertisement, across the world, which tells people about the excellence of Staffordshire businesses, demonstrating its commitment to the area and the local economy where it has its roots.
"JCB is a vital part of the region's economy."
The deal means that in the last three years A-Plant has placed orders with JCB worth more than £140 million.
The equipment will be distributed throughout its network of over 175 service centres.
A-Plant marketing director Asif Latief said: “The latest products are more innovative, productive, safer, greener and more sustainable.
"We are delighted to have placed this latest order with JCB, which demonstrates our commitment to working with leading brands.
"It is part of our continual fleet investment programme which has seen A-Plant invest over £300 million during the last two years.
“Among the 1,300 pieces of new equipment, we will be supplying 162 generators into A-Plant's rapidly expanding power solutions division.
"Customers tell us that their number one priority is reliability, closely followed by availability and quality, so it is vital that we continue to meet these key requirements.”
A-Plant forms part of FTSE 100 company Ashtead Group plc and is the UK's largest equipment rental company with more than175 Service Centres nationwide, more than 3,600 employees and over 35,000 customers in the construction, industrial, infrastructure and events sectors.
