PML 1000 Lifting Magnet - Safe, High Capacity, Quick Release

In busy plate yards and fabrication shops, you can almost hear the collective sigh when a power-free lifter clicks on and a 1-ton sheet just… moves. If you’re weighing options, the pml 1000 lifting magnet sits in that sweet spot: big enough for real work, small enough for one person to handle.

Dawei’s Permanent Magnetic Lifter—PML Type—comes in 300, 600, 1000, and 2000 kg ratings. Origin: Donglv Industrial Park, Qingyuan District, Baoding City, Hebei, China 071100. I visited the area a few years ago; it’s a quiet manufacturing hub where magnets, hoists, and heavy kit are everyday conversation.

Why shops are shifting to permanent lifters

Two trends: fewer hands on the floor and tighter safety audits. No power cables, faster picks, fewer slings—these devices tick all three boxes. Also, with steel prices wobbling, productivity wins matter. Many customers say they recoup the cost in months, not years.

Specification snapshot (real-world use may vary)

Notes: based on flat, clean, low-carbon steel with full contact. Surface roughness, air gaps, and alloy content reduce capacity—sometimes a lot.

What’s inside and how it’s built

- Materials: NdFeB magnet blocks, low-carbon steel yoke, machined pole shoes, 45# steel cam/shaft, safety latch handle.
- Methods: CNC machining, pole shoe grinding for flatness, epoxy sealing, torque-calibrated assembly, 100% proof pull-off test.
- Testing: breakaway on clean test plate per EN 13155 principles; labeling per ASME B30.20/BTH-1; sample salt-spray for coating life.
- Service life: around 8–10 years in indoor use; inspect before each use and annually by a competent person (yes, paperwork matters).

A shop manager told me their pml 1000 lifting magnet measured ≈3,100 kg breakaway on 50 mm Q235 plate during acceptance—comforting margin, though you still lift only the rated load. To be honest, thin plate needs extra care.

Where it shines

Flat plate cutting tables, flame/plasma nests, warehouse picking, dockside plate staging, steel service centers, and even round bar handling with correct contact area. Advantages: no power, quick on/off lever with lock, compact, predictable performance.

Customization and field notes

- Custom pole shoes for round/uneven stock
- High-temperature versions (ask for ≤120°C rated options)
- Private label and bilingual nameplates; pull-test certificates per batch

Case 1: A shipyard paired two pml 1000 lifting magnet units on a spreader bar to lift 12–16 mm plate sections—fewer slings, cleaner edges. Case 2: A small fab shop cut loading time by ~35% moving remnants off a laser bed. Feedback? “Handle lock feels positive; operators trust it.”

Compliance, paperwork, and good habits

Look for CE/EN 13155 conformity, factory ISO 9001, and markings per ASME B30.20/BTH-1. Keep surfaces clean, verify contact, de-rate for thin/rough/hard alloys, and document annual inspections. Simple, but it prevents the heart-in-mouth moments.
