The Monde JS RT series hydraulic excavator shear is the boom-mounted industrial cutting attachment for demolishing metal structures, recycling vehicles, cutting beams and tubes and dismantling ships — applications where a hydraulic breaker cannot cut and where manual cutting with an angle grinder or thermal cutting is slow and dangerous.
With a cutting force of up to 65 tonnes and a tip force of up to 295 tonnes, the Monde JS-RT hydraulic excavator shear cuts metal profiles, I-beams, steel plates, cables and vehicle bodies in a fraction of the time required by alternative methods.
The Monde JS-RT hydraulic excavator shear is available in 5 models — JS280RT, JS350RT, JS380RT, JS450RT and JS480RT — covering excavators from 14 to 39 tonnes, with weights between 2,100 and 4,600 kg and maximum jaw openings between 485 and 740 mm.
Built from Q460, NM360/400 and Hardox 450/500, with an integrated cooling system for 8 hours of continuous operation and hydraulic safety locks, the Monde hydraulic excavator shear is the industrial cutting solution for professional demolition and metal recycling operators. Key advantages of the Monde hydraulic excavator shear
• Cutting force up to 65 tonnes — tip force of 295 tonnes — the Monde JS-RT hydraulic excavator shear generates up to 65 tonnes on the main jaws and up to 295 tonnes at the tip, where the lever geometry concentrates the force on a minimal area. This tip force allows cutting steel structures with cross-sections impossible to tackle with smaller hydraulic shears or with breakers.
• 2–3 times faster than a hydraulic breaker — the Monde hydraulic excavator shear cuts a beam or a metal column in a single 10–30 second cycle compared with the tens of minutes of percussion required by a hydraulic breaker to fragment the same structure. On an industrial demolition site processing 50–100 tonnes of metal per day, the productivity difference translates directly into the cost per tonne processed and the number of site days required.
• Rotating — access from any angle — the Monde JS-RT hydraulic excavator shear is rotating, allowing the operator to position the jaws perpendicular to the structure being cut regardless of its orientation relative to the excavator. This rotational freedom is essential on demolition sites where structures are in unpredictable positions and where frequent repositioning of the excavator would drastically reduce productivity.
• Q460, NM360/400, Hardox 450/500 — the hydraulic excavator shear is built with high-strength steels matched to the extreme demands of metal cutting: Q460 for the load-bearing structure, NM360/400 for the jaw body, Hardox 450 and 500 (430–530 HB) for the cutting edges — the zones with the highest abrasive and thermal contact when cutting structural steel.
• Integrated cooling system — 8 hours of continuous operation — the Monde JS-RT hydraulic excavator shear includes an integrated cooling system for the hydraulic circuit that allows continuous operation over full 8-hour shifts without overheating. On sites with high daily output of demolition or metal recycling, this ability to operate continuously without mandatory cooling breaks is a direct operational differentiator over shears without an active cooling system.
• Hydraulic safety locks — the Monde hydraulic excavator shear is equipped with hydraulic locks that prevent accidental opening or closing of the jaws upon loss of hydraulic pressure. This safety feature is mandatory in demolition and rescue applications where loss of jaw control under load can cause serious accidents.
• 5 models for 14–39 tonnes — JS280RT (14–18t), JS350RT (20–28t), JS380RT (20–28t), JS450RT (28–39t), JS480RT (28–39t) — the Monde hydraulic excavator shear covers the medium and medium-heavy classes of excavators used in industrial demolition and metal recycling. UZINEX engineers select the right model for your excavator based on tonnage and available hydraulic flow.
• 60-month UZINEX warranty — spare parts for jaws and cylinders in stock in Iași, guaranteed 24–48 hour national technical support.

Demolition of industrial steel structures — halls, warehouses, steel bridges, trestles — is the benchmark application for the Monde JS-RT hydraulic excavator shear. Industrial structures in structural steel of grade S355 or higher, with sheet thicknesses of 15–40 mm and HEA/HEB profiles with flanges of 200–400 mm, are cut efficiently by the hydraulic excavator shear without thermal cutting or access to a power grid.
Recycling of heavy vehicles — trucks, buses, agricultural and construction machinery — is a major application for the hydraulic excavator shear in dismantling and auto recycling centres. The bodies and frame of a 20-tonne truck can be fragmented and sorted into metal categories in less than an hour with the hydraulic excavator shear, compared with 4–6 hours using manual methods with an angle grinder and a portable hydraulic press.
Cutting and portioning metal materials for recycling — I-beams, UPN and IPE profiles, thick-walled industrial tubes, steel plates and steel cables — is carried out directly on the scrap collection platform with the hydraulic excavator shear, eliminating the operations of moving the material to a separate press or industrial saw.
Dismantling river and sea-going vessels is a specialised application of the hydraulic excavator shear, where thick-plate structures (10–30 mm) and the complex hull profile require an attachment with a large jaw opening — the JS450RT and JS480RT models, with openings of 700 and 740 mm, are dimensioned for the structural sections of medium-tonnage vessels.
Rescue and emergency response operations — freeing people trapped in vehicles or collapsed structures — use the hydraulic excavator shear for the rapid cutting of metal structural elements blocking access, in situations where the speed of intervention and the available cutting force are critical. Hydraulic excavator shear vs. the hydraulic breaker — when each choice is justified
The hydraulic breaker for excavator is the solution for fragmenting concrete, rock and mixed concrete-steel structures where repeated percussion disintegrates the material. On pure metal materials — structural steel, alloys, thick plate — the hydraulic breaker is inefficient: percussion deforms the metal but does not cut it, prolonging operations by 5–10 times compared with the hydraulic excavator shear on the same materials.
The hydraulic excavator shear is the right tool whenever the objective is the controlled cutting of metal, not fragmentation by percussion. On a mixed demolition site with reinforced concrete and metal structures, combining a hydraulic breaker (for concrete) with the hydraulic excavator shear (for structural metal) through rapid attachment changes with a Monde DEHN quick coupler maximises productivity on both material types without replacing the base machine.
Compared with the heavy duty excavator bucket or the rock bucket , the hydraulic excavator shear is a specialised processing attachment — it does not excavate, but cuts and sorts already-excavated metal or existing metal structures. The two types of attachment are complementary, not alternatives. Frequently asked questions about the hydraulic excavator shear
What maximum thickness of structural steel does the Monde JS-RT hydraulic excavator shear cut?
The maximum cutting thickness depends on the chosen model and the steel grade. On S235/S355 structural steel, the JS450RT and JS480RT models cut plates up to 40–50 mm thick and HEB400 profiles in a full section. UZINEX engineers confirm the cutting capacity for the specific materials of your project at the quotation stage. Does the hydraulic excavator shear require additional hydraulic flow compared with the standard bucket?
Yes — the JS-RT hydraulic excavator shear requires 180–300 L/min at 250–350 bar, parameters available on 14–39 tonne excavators with a high-pressure hydraulic circuit. UZINEX checks the parameters of your excavator's hydraulic circuit before delivery to confirm compatibility and avoid the under-flow that reduces the available cutting force. How long does it take to replace worn jaws on the hydraulic excavator shear?
The jaws of the Monde JS-RT hydraulic excavator shear are independently replaceable components, without complete disassembly of the attachment. UZINEX keeps replacement jaws in stock in Iași for all 5 models in the JS-RT series, with immediate delivery to minimise machine downtime. Is the Monde hydraulic excavator shear eligible for SEAP/SICAP public procurement?
Yes. UZINEX provides the complete technical documentation at delivery. The product can be added directly to SEAP/SICAP from the product page. UZINEX is a member of the Enterprise Europe Network and delivers equipment for projects with European and NRRP funding. Why UZINEX for the hydraulic excavator shear
