What Are Test Weights Used For?
Ensuring the safety and compliance of lifting equipment is a top priority for engineers, crane specialists and site managers alike. One of the most effective ways to do this is through test weight hire, which plays a vital role in load testing and proof load testing of various lifting and load-bearing structures.
At LMT Hire Ltd, we supply over 500 tonnes of cast steel test weights in a wide range of sizes — from 56lb hand weights to 7,400kg block weights — making us a trusted partner for lifting professionals across the UK.
Our test weights are commonly used for:
- Overhead and mobile cranes
- Jib cranes, gantry cranes and runway beams
- Hoists and Hiabs
- Lifting beams and lift shaft beams
- Excavators and other heavy equipment
If you’re unsure what you need, our team is always happy to advise and ensure you get the right solution for your specific testing requirements.

Why Is Load Testing So Important?
Load testing is a controlled process where test weights are applied to equipment — such as cranes, hoists, or lifting beams — to confirm it can handle its rated load safely. Also known as proof load testing, this process is essential for:
- Spotting weaknesses before they cause equipment failure
- Certifying equipment as safe for operational use
- Meeting UK legislation, including LOLER and PUWER requirements
- Verifying repairs, modifications, or new installations
- Preventing downtime and improving reliability
- Whether you’re testing after an incident or before equipment goes into use, proper load testing reduces risk and improves overall safety on site.
