Cayman: Mobile shears for scrap recycling
The Cayman range of hydraulic mobile shears is the ideal solution for medium to heavy scrap recycling operations. With advanced technology and high-quality steel construction, these excavator-mounted shears are designed to meet the diverse needs of industrial and demolition sites. Developed by Zato over two decades ago, the Cayman demolition and recycling shear continues to excel, offering dependable reliability, durability and cutting strength. Available in eight sizes and easily switched between boom and bucket mounting, it adapts to a wide range of carriers and materials on site.
General features
- Engineered for optimal performance and durability
- Reduced maintenance time and costs
- Maximises the value of processed materials
Built as heavy-duty mobile scrap shears
As purpose-built mobile scrap shears, the Cayman brings its cutting force directly to the material instead of moving scrap to a fixed machine. Drawing on long experience as mobile scrap shear manufacturers, Zato pairs the Strenx 700 frame with a high-bore cylinder and four-edge blades so the attachment keeps performance high while maintenance time stays low.
- Robust Strenx 700 frame designed to protect mechanical components
- High-bore cylinder engineered for powerful cutting forces
- Solid, compact beak for track cuts up to 70 kg/m
- Interchangeable blades featuring four cutting edges
- Streamlined 360° hydraulic rotation for reduced maintenance
- Versatile mounting for both boom and bucket placements

FAQ
What are mobile shears and how do they differ from a stationary shear?
Mobile shears are hydraulic cutting attachments fitted to an excavator, so the cutting force is brought to the material on site rather than feeding scrap into a fixed machine. This makes them flexible for demolition and scrapyards. Zato’s Cayman is a mobile shear available in eight sizes for medium to heavy scrap.
What is the advantage of interchangeable blades with four cutting edges?
Each Cayman size lists a recommended excavator-weight range for boom and for bucket mounting, from small 4–6 tonne carriers up to machines of 110 tonnes. The right model depends on your carrier and the scrap you cut; Zato’s team matches the shear to your equipment and application.
What makes a demolition shear durable?
Blades with four cutting edges can be rotated as they wear, so each blade lasts longer before replacement, reducing consumable costs and downtime. On the Cayman, the interchangeable blades work with a high-bore cylinder and rigid Strenx 700 frame to maintain cutting performance over time.
Can the Cayman rotate for easier positioning?
Yes. The Cayman features streamlined 360° hydraulic rotation, which lets the operator position the jaws precisely for each cut while keeping maintenance requirements low. This improves productivity on complex demolition work and awkward scrap.
What materials can the Cayman process?
The Cayman is designed for medium to heavy ferrous and non-ferrous scrap, including lightweight HMS2, heavy HMS1, cars, cast iron and industrial demolition scrap. Its compact beak can handle track cuts up to 70 kg/m. Zato can advise on the best size for your specific materials.
