Double-cylinder hydraulic shear series

The supplied drawings cover two related attachment families: rotating eagle-beak shears for excavator metal cutting, and full-blade twin-cylinder shears for heavier scrap processing. The page keeps their model families separate so carrier and cutting data are not mixed.

Applications and configuration

Scrap steel cutting, vehicle dismantling, structural steel processing and demolition work.
RT models add hydraulic rotation for positioning the jaws around irregular steel sections.
Full-blade models are selected by carrier class, blade opening, depth, section size and hydraulic supply.
Replaceable blades, reinforced pivot points and dual cylinders support serviceable heavy-duty operation.

Selection information

Confirm excavator make and operating weight, hydraulic flow and pressure, mounting pins and centre distance, target steel profile, required opening and whether a rotating head is needed. The final carrier check and order drawing take priority over a model range.

Equipment photos

Reference images and drawing extracts are shown for configuration review. Final blade, bracket and pin dimensions are confirmed against your excavator before the order.
