WORLDWIDE LOAD TESTING SPECIALISTS

Specialist load testing
since 1979.

Established in 1979 by John David Graham and Norman David Graham, the company was formerly known as Water Weights. WWLTS pioneered the use of water-filled bags for proof load testing in Africa.

Today, our work brings together independent examination, load testing, detailed reporting and specialist equipment hire and sales. We support customers working with lifting tackle, workshop machinery and high-capacity cranes across demanding industrial environments.

Our focus is practical: understand the equipment, plan the appropriate inspection and test, and give the customer clear findings they can use.
