Hart Door Systems supplies over 60 doors to fellow NEAA member over 30 year period


Komatsu, one of the world leading manufacturers of construction, mining and utility equipment, invests in industrial door solutions from Hart Door Systems.

The Komatsu UK plant in Birtley, Co Durham officially opened in 1987. Safety and reliability are paramount in this 200,000 sqm facility, which has produced over 60,000 units.

Although only a small part of the building, industrial doors cause the biggest problems if they are not designed with the environment and usage in mind.


Komatsu and Hart Door Systems began their relationship in the 80’s with the installation of one of Harts earliest prototype Speedors. Due to the success of the door, four Speedors and four roller shutters were installed in 1992.
As a British manufacturer, Hart provides Komatsu with a first-class service, offering support and parts when required and due to the reliability of the doors, maintaining the safe, efficient running of the facility.

Each Hart door is made to measure and each safety device and activator is fitted to suit specific areas, giving Komatsu a safe and secure working environment for its employees.


Large facilities like Komatsu UK bring with it many challenges such as the need to ensure a safe and efficient flow of large vehicles associated with production. Hart delivers doors that are engineered for endurance while taking into account the environment and daily usage.

Over the years, Hart has installed over 60 doors to the facility across a range of door types including Speedor Cleanrooms, Speedor Storms and electric roller shutters. Only recently Hart has replaced some of the original doors installed in 1992 giving Komatsu almost 30 years of usage from the doors.

“Komatsu has used Hart Doors for many years as we find them reliable in service.”

Mark Stephenson, Production Engineering Manager
Komatsu UK

“Komatsu’s operation in the North East is a huge success, manufacturing excavators, dump trucks, dozers and loaders for a global market. This is a fast- moving, highly efficient, business and we play our part by delivering doors that are reliable and long lasting.”
