M&M Test Weights work with a number of overhead crane manufacturers, who manufacture, install and modify gantry cranes, goliath cranes, chain and wire rope hoists and swing jib cranes.
Lastly we are able to provide the relevant weight needed to achieve crane safe working load (SWL), and proof load (overload) in the exact load increments our customers require.
Please get in touch to discuss your overhead crane testing requirements!


Helpful and knowledgeable staff with a great selection of test weights and cradles to suit, competitive pricing and flexible when required with regard to deliveries. M and M always provide a great service."
