Actually picks up the load with a spring-loaded lock that keeps positive clamping force throughout the lift — no need to worry about slippage during vertical or horizontal plate handling, and we usually stock models from 0.8 up to 30 tons depending on your typical plate thickness.
The jaw opening ranges from 0 to 90mm depending on the model you select, and the die-forged low carbon alloy steel construction with high-frequency quenching on the cams gives it better wear resistance than standdard untreated clamps in most cases. It's pretty much designed for steel plate handling and structural lifting in fabrication shops, but it's not ideal for curved surfaces or pipe lifting — that's a different tool entirely.
What it does is engage the plate edge automatically when you start lifting, and the anti-slip design combined with heat-treated cams holds tight even with some vibration during the move. Most buyers go with the 10-ton model for general fabrication work, though you'll want a COA on the specific batch to confirm the hardness specs meet your internal safety requirment.
One thing you wouldn't think to ask about — the weight range is 2.8 to 155kg depending on capasity, so the larger units need two people or a forklift just to position them on the plate. Storage should be dry with the lock released to avoid spring fatigue over 20 days or so of sitting idle.
The jaw opening depends on the model, but it covers plates from 0 up to 90mm thick. For example, the 0.8-ton model handles plates 0-20mm, and the larger ones go up to 90mm. Check the specific model's specs for exact thickness range.
Yes, we typically require a minimum order quantity, but for sample testing we can often do a single unit. Just reach out with the model capacity you need, and we'll confirm the MOQ for that specific size.
Standard lead time is about 15-25 working days, depending on stock levels. Higher capacity models like 30 tons might take a bit longer if not in stock, but we'll give you a confirmed timeline with your order.
Yes, we provide a certificate of compliance showing conformance to industrial lifting safety standards. If you need additional test reports or material certificates, let us know and we can include them with the shipment.
The spring locking mechanism automatically engages when the clamp grips the plate, preventing accidental release. For the anti-slip design, just keep the cam and jaw surfaces clean from grease or debris—no special maintenance beyond regular inspection.
