PML 1000 Lifting Magnet – Heavy-Duty, Safe, CE-Certified

Hands-on Notes: The PML-Type Magnet Everyone’s Asking About

If you lift steel plate day in, day out, you’ve probably eyed a Pml 1000 Lifting Magnet at some point. Dawei’s PML series (300/600/1000/2000 kg) has been popping up in docks, fabrication shops, and steel service centers from Baoding to Birmingham. I visited a plant in Hebei a while back—Donglv Industrial Park, to be exact—and, to be honest, I liked the simplicity: lever, safety lock, clean magnetic circuit, done.

What’s trending in magnetic lifting

Two things: safer thin-plate handling and fewer slings on the floor. Actually, the big driver is labor productivity—fewer hooks, faster picks, less re-choking. Many customers say magnets are cutting cycle time by around 20–30% on repetitive plate moves. The other trend is standards-driven: buyers increasingly ask for proof of breakaway factors and traceable testing. Sensible, given real-world variables like surface rust and air gaps.

Key specs at a glance

Model	Rated Load	Breakaway (lab)	Min Plate Thickness	Temp Range	Net Weight
PML-300	300 kg	≥ 3.0× rated (≈900 kg)	≥ 10–12 mm	-40 to +80°C	≈ 8–10 kg
PML-1000	1000 kg	≥ 3.0× rated (≈3000 kg)	≥ 20–30 mm	-40 to +80°C	≈ 40–45 kg
PML-2000	2000 kg	≥ 3.0× rated	≥ 35–40 mm	-40 to +80°C	≈ 75–85 kg

Notes: Values are typical; real-world use may vary with material grade, surface roughness, air gap, and temperature.

Magnet type: NdFeB (high-energy neodymium) with low-carbon steel pole shoes
Safety: mechanical lever with positive lock; closed-flux circuit to minimize stray fields
Testing: pull-off tests on S235/S355 plates; gauss verification at pole face

How it’s built and verified

Materials come in from Baoding-region mills, then rough-machined housings, ground pole faces, assembly of the magnet stack, and the cam/lever install. After that: demag checks, air-gap trials (0–0.5 mm shims), and breakaway tests. Internal procedures track to ASME B30.20 and EN 13155 principles—yes, I asked to see the pull charts. Service life? With clean contact surfaces and no impacts, operators report 8–10 years. Keep it away from heat above 80°C and you’ll do fine.

Where it shines

- Plate cutting lines and press shops moving ferromagnetic sheets;
- Warehouse picking of flats and flame-cut parts;
- Dockside steel handling where slings slow things down.

Quick case: a mid-size service center swapped two slings for one Pml 1000 Lifting Magnet on 10–20 mm plate. Cycle time per lift dropped from 2:40 to 1:50, and operators liked the predictable release—no stuck hooks, no pinch points.

Vendor snapshot (quick compare)

Vendor	Range	Standards/Docs	Notable
Dawei (Hebei, CN)	300–2000 kg	Test data + factory ISO 9001	Good value; thin-plate focus
Brand A	100–3000 kg	EN 13155 approach, CE docs	Wider accessories
Brand B	500–2000 kg	ASME B30.20 compliance notes	Heavier-duty housing

Customization and practical tips

Custom pole shoes for curved parts or flame-cut surfaces
Higher-temp magnet grades for hot workpieces (ask for data)
Proof-load certification sheet and serial traceability on request
Maintenance: wipe pole faces, avoid paint/rust buildup, monthly function test
Rule of thumb: any air gap—mill scale, paper, paint—reduces capacity fast

Compliance and documents

Request a dossier showing: factory ISO 9001, pull-off test sheet for your Pml 1000 Lifting Magnet, operator manual referencing ASME B30.20/EN 13155 use conditions, and material traceability. Some buyers also ask for MMPA guidance notes—can’t hurt.
