Highly Accurate Digital Industrial Crane Scales

Time and money can be saved by weighing the load while moving it. We offer a comprehensive capacity range from 0~500 kg up to 0~200 tons with robust professional designs that enables solutions to a variety of different applications in industrial environments. The scales have a clear display and they can be equipped with hand-held display units or radio data transmission to a ground station or a PC in the office. Information on material, customer, price, stock etc.  can also be transmitted. There are special models for foundries and for weighing long pieces.

Model Sigma PCS

An economic robust and compact crane scale
it allows you to weigh reliably and accurately during transfer, eliminating the need to move objects to and from stationary scales.

Easy to use
You just hang the crane scale on the crane hook and switch it on. Everything is ready for weighing.

Rugged, safe and accurate
Sigma ECS crane scales are designed and manufactured for demanding industrial use. The breaking strength of the load cell is five times the rated capacity. An advanced measuring algorithm and special movement compensation ensure accurate weighing even if the load is swinging.
