If you currently buy this counterweight as a casting, we can re-engineer it as a welded fabrication — no tooling, no minimum batch, no pattern lead time.
The box is filled with compacted steel sand at 4.8 t/m³ — roughly double the density of concrete-filled counterweights — and every unit is weighed before the cover plate is welded on. Send us your existing casting drawing or a sample and our engineers will return a welded-fabrication proposal within 24 hours. Full detail on cast-to-welded conversion.
The more detail you share, the faster and more accurate your quotation will be. Not sure about something? Just email us what you have.
No drawings? Send us photos or the forklift brand & model — our engineers will work from that and send a technical review within 24 hours.
We regularly produce counterweights for Komatsu, Mitsubishi, Doosan, Clark, Hangcha, Heli, TCM, Nissan and other brands. If your model is not listed, send us the brand & model or a drawing and we will confirm fitment.
The welded box construction filled with compacted steel sand achieves the exact required weight at a lower material cost than a solid steel block, while keeping the counterweight structurally strong. It is the standard construction for large counterweights.
Yes. MOQ is 1 unit for samples and 5+ units for production batches. Sample lead time is 45 days depending on complexity.
Yes. We routinely machine exhaust clearances, tow pin bosses, and other features into the counterweight per the forklift model or your drawing.
Standard finish is shot blasting + anti-rust primer + high-durability enamel paint. Custom RAL colors and logos are available on request.
Yes, and it is one of our most common engineering requests. Send us the existing casting drawing or a physical sample and we will re-engineer it as a welded box filled with compacted steel sand. You avoid pattern tooling entirely, MOQ drops to 1 unit, and design changes are handled by re-issuing the drawing rather than cutting a new pattern.
We reply by email within 24 hours with a technical review and quotation. Attach drawings or photos directly in the email.
