Choosing test weights for safe work load or quality tests

Test weight accuracy

Weights used for proof load and quality tests do not need to be as accurate as calibration weights used to test weighing equipment.
You can choose cast iron weights calibrated to the M1 standard as used for testing scales if you prefer, but we also offer other class weights, which have a tolerance 10 times greater than the M1 class. Reducing the accuracy makes the weights less expensive because less time is required to adjust them, and because the tolerance is larger the weights are less likely to drift outside the specified tolerance when using in the more demanding conditions of proof load testing.

Test weights come in all different shapes and sizes depending on what they are made of, how heavy they are and how they are used.

Block Weights for forklifts and cranes

Cast iron block weights are used for high capacity proof load testing applications.

The weights come in two different designs, one design as per the picture includes a fork guide and a loop in the top so they can be lifted by a fork lift truck or a hoist/crane and the other design can be moved with pallet truck scales or a crane/hoist. The second design can also be used with a fork lift truck but because the first design uses a closed fork guide this is the one we recommend for fork lift trucks because it is a safer load.

The units below are manufactured from steel , however we also have cast iron options available.

Cast iron M3 class weights

Cast iron M1 class weights

Cast Iron M1 class weights are ideal for proof load testing requirements where the weights need to be carried but they can also be moved on pallets or in cages so they make a flexible choice for proof load testing.

These weights are supplied to M1 tolerances and are normally purchased with one of the certificate options available.

These weights are available in 5 kg, 10 kg or 20 kg to suit your requirements.
