Donghong Attachment Hydraulic steel shear

As an attachment with no drive of its own, a steel shear such as the DHG-06 draws its hydraulic power entirely from the carrier through the quick-coupler. Jaw opening, cutting force and dead weight are the key figures for steel shears, and they determine the size chosen to match the operating weight of the excavator in use.

Steel shears like the DHG-06 are used in metal recycling and in dismantling steel structures, for example cutting beams, pipes and reinforcement bar down to pieces that can be transported. The quick-coupler and hydraulic connection decide which carriers the attachment can be fitted to. Tools of this kind are often used at scrapyards and when dismantling steel-framed halls and structures, where the priority is breaking material down quickly on site.

Buying a used hydraulic steel shear means checking the blades for chipping and whether they can still be re-sharpened, the tightness of the hydraulic cylinders and the play in the jaw bearings. The quick-coupler mount should also be checked for wear and for matching the size of one's own carrier, since a shear without the right connection cannot be used at all.
