Calibration Block Weights

Block Weights are typically used for safe load testing of over head cranes and lifts etc or calibrating weigh bridges and large capacity scales. Block Weights are normally supplied in nominal adjustment for safe load applications  ie +/- 5% or adjusted to M1 (+/-0.005%) and certificated by Trading Standards for calibration purposes.

They are supplied painted in red oxide primer but you can request a specific colour, (surcharge does apply).

We make bespoke weights for specific applications and also make Block Weights in excess of 2000kg's up to a maximum of 8500kg's. 3D CAD design service available for bespoke test weights and sinker weights. 

If your Block Weights require serial numbers Stencilled or Stamped on them, or for further information please contact us.
