Materials And Construction
- Die cast aluminium enclosure
- Stainless steel shackle and hook
Customisation Options
- Capacity from 30 kg to 300 kg
- Unit set configured for the destination market
Use Guide
- Select a capacity above the heaviest planned lift; safe overload is a protection limit, not a working range
- Inspect the shackle and hook for wear and deformation before each shift
- Zero the scale before each lift rather than trusting the last reading
Certification
- OIML Class III
How It Compares
| OCS-C1 crane scale | The OCS-C1 covers 1000 kg to 5000 kg with a 30 mm display, remote operation to 10 m and a 360 degree swivel hook. The OCS-L is the compact model below 300 kg. |
|---|---|
| GS-006 mechanical hanging scale | The GS-006 is a mechanical dial scale with no battery. The OCS-L is the digital option with tare, hold and an overload alarm. |

View specifications →Crane Scale Safety And Inspection Basics
A crane scale sits in the load path of a lift. Treat it as lifting equipment first and a measuring instrument second.
Shear Beam S Type And Column Load Cells Compared
Four structures cover nearly every weighing build. Choosing the wrong one creates mounting problems that no amount of calibration will fix.
