Makes you think.

"The Lightest & Strongest Machines in the World".

To support Premier Cycle Company's motto Kirkaldy's Testing Works carried out Pulling & Bending Stress tests on their steel "Helical Tubing" bicycle frames in 1893 which were proudly published in Premier's sales brochures.

From 1893 the system pumped 6.5 million gallons each week which grew to 32 million gallons by 1933.

But this water pressure did not satisfy Kirkaldy's needs so an intensifier was installed raising the pressure to 4,500 psi ! (310bar).

In 1883 London was introduced to the Hydraulic Power Company, a vision to offer a cleaner more compact alternative to steam engines to power London.

Pressurised water was pumped around by a series of Pumping Stations at 700-800 pounds per square inch (55 bar).

What do you keep in your safe?

David Kirkaldy kept his prized possessions in his large safe, a fine set of Kirkaldy patent micrometers, for accurate measuring, along with other calculating and measuring instruments.

Load testing Sydney Harbour Bridge in 1932.

In 1865 David Kirkaldy commissioned a 116ton, 47’ 7” long water powered Universal Testing Machine that can apply 1,000,000lb of force.

We still operate that machine today in London SE1.

@GScott42087 @RobertElms We are a working museum housing much of Kirkaldy’s testing equipment and located on the ground floor and basement of No99, we’ve been here since 1874, previously located at The Grove from 1865/66.

@RichardRf020370 @RobertElms We open roughly twice a month due to the fabric of the works and one of those days we run our Victorian 47’ 7” long, 116 ton Universal Testing Machine that can apply a 1,000,000lb of force all powered by hydraulic water.

[Facts Not Opinions @TheTestingWorks]

@RobertElms We are the world’s oldest independent material testing house founded in 1874, the works was originally powered by hydraulic water provided by London Hydraulic Power.

We helped build the Sydney Harbour Bridge, Tower Bridge, the original Wembley Stadium amongst other iconic builds
