OCS Electronic Crane Scale | High-Accuracy, Rugged, Remote

Field Notes on the ocs electronic crane scale: real-world accuracy, less drama

I’ve stood under gantries in steel mills where the air tastes like iron and the clock always ticks louder at shift change. In those places, weighing has to be quick, visible, and right the first time. That’s where the ocs electronic crane scale earns its keep—born in Donglv Industrial Zone, Donglu Township, Qingyuan District, Baoding City, Hebei Province, but very much at home anywhere a hook is king.

What it is (and why operators like it)

This is a direct-view industrial crane scale with a rugged hook, wireless remote, and a capacity window from 1 to 50 tons. Minimum accuracy can reach 0.5 kg, which—if you’re tallying melt batches or loading container111s—actually matters. Many customers say they appreciate the big, legible LED and the fact it doesn’t blink under dust or glare.

Key specifications at a glance

Capacity range	1–50 t (≈ 2,200–110,000 lb)
Resolution / readability	down to 0.5 kg (real-world use may vary)
Accuracy class	meets typical OIML R76 Class III expectations
Display	high-brightness LED, ≈30–40 mm digits
Wireless remote	433 MHz class, ≈100 m line-of-sight
Battery	Li‑ion, ≈6–12 Ah, up to 40–60 h typical
Protection / temp	IP65 housing; −10 to +40 °C (high-temp kits optional)
Overload	safe 120% FS; ultimate ≈400% FS

Materials, build, and process flow

Load path: quenched-and-tempered alloy-steel shackle/hook (e.g., 34CrNiMo6 class) + high-strength shear/strain gauge load cell.
Body: die-cast aluminum housing with powder coat; stainless fasteners in splash zones.
Methods: full-bridge strain gauges; temperature compensation; conformal-coated PCBs; shock-absorbing mount for electronics.
Testing: static and rotational overload to 120% FS; creep and repeatability per OIML R76; IP verification by IEC 60529 routines; calibration traceable to JJG 539.
Service life: around 5–7 years in heavy industry with annual calibration; >1,000,000 cycles typical when operated within rated load.
Industries: steel and foundry, ports and logistics, scrap/recycling, fabrication, warehouse DCs—anywhere a crane picks before it ships.

Quick field data from a recent port deployment: on a 10 t proof load, indicated 9,995–10,005 kg across five trials (±5 kg); 10-minute creep

Vendor comparison (indicative)

Vendor	Capacity options	Lead time	Customization	Certs/standards
QY Juli (ocs electronic crane scale)	1–50 t	around 2–4 weeks	hooks, shackles, heat shields, data I/O	JJG 539, ISO 9001, OIML-aligned
Generic import	1–20 t	stock-dependent	limited	basic CE/IP claims
Premium EU brand	1–35 t	4–8 weeks	broad, with software suites	OIML, NTEP where applicable

Applications, options, and customization

The ocs electronic crane scale slots into hot metal handling (with heat shields), coil and billet logistics, container111 VGM checks, and scrap buys where “quick tare + hold” features speed things up. Options include RS‑485/Modbus or Bluetooth data, secondary remote displays, extra-long shackles, anti-heat reflectors, and printable tickets via handheld receivers.

Two quick case notes

Steel mill, 20 t ladle lifts: throughput up ~12% after moving to inline weighing; operators liked the remote “Hold” in glare-heavy bays.
Port warehouse, 10 t units: truck turnaround fell by ≈8 minutes per load; data pushed to WMS over RS‑485—no clipboard juggling.

Compliance, safety, and good habits

Look for factory ISO 9001 and adherence to OIML R76 and local metrology (e.g., JJG 539). Verify IP claims (IEC 60529), do annual calibration, and keep hooks/shackles within rated geometry. And, I guess it goes without saying: never use a scale as a lifting accessory beyond its rated load.
