The Monde YZJ310 metal-structure demolition shear is the highest-force hydraulic cutting attachment in the UZINEX range — designed for heavy industrial demolition and processing large metal scrap where raw cutting force and jaw opening are the determining parameters.
With a lateral cutting force of 295 tonnes, a frontal force of 122 tonnes, a maximum opening of 745 mm and a weight of 3,300 kg, the Monde YZJ310 metal-structure demolition shear is calibrated for the 12–35 tonne excavators used in industrial demolition, heavy scrap-metal processing and dismantling large machinery.
The defining design feature of the Monde YZJ310 metal-structure demolition shear is the installation of the hydraulic cylinders in an inverted position compared with the conventional configuration — a solution that maximises the effective jaw clamping force at the same hydraulic flow and pressure, without increasing the attachment weight or placing additional demand on the excavator's hydraulic circuit.

Key advantages of the Monde YZJ310 metal-structure demolition shear
• Lateral cutting force 295 tonnes — the Monde YZJ310 metal-structure demolition shear generates 295 tonnes of cutting force on the lateral blade — the main cutting zone used for sectioning I-sections, HEA/HEB, bridge beams and heavy steel structures. This force covers the structural sections used in heavy-class industrial halls and metal construction infrastructure, including S355 steels and equivalents.
• Frontal cutting force 122 tonnes — the Monde YZJ310 metal-structure demolition shear develops 122 tonnes of frontal force at the jaw tips — the zone used for initial penetration into structures and for cutting pieces positioned deep within the shear opening. The 295t lateral / 122t frontal combination allows efficient operation on sections of varying sizes without repeatedly repositioning the material.
• Maximum opening 745 mm — the Monde YZJ310 metal-structure demolition shear opens its jaws to 745 mm, covering heavy-class structural sections: HEA/HEB beams up to 300 mm wide with added gusset plate, composite structures and packs of sections fixed together during demolition. The 745 mm opening is the critical parameter that determines whether a section can be gripped and cut in a single movement or requires successive cuts.
• High-capacity hydraulic cylinders in inverted position — the Monde YZJ310 metal-structure demolition shear uses hydraulic cylinders installed in an inverted configuration compared with conventional shears. This positioning changes the geometry of force application on the movable jaw, increasing the effective clamping force at the rated pressure of the excavator's hydraulic circuit without requiring an auxiliary circuit with higher parameters or modifications to the machine's hydraulic system.
• Full range of metal materials — the Monde YZJ310 metal-structure demolition shear processes round steel, round pipe, channel, I-beam sections, steel plate, cables and any other form of metal structure common in industrial demolition and ferrous-scrap collection. The material versatility is made possible by the combination of the wide 745 mm opening and the bilateral cutting force.
• Construction from high-strength steel with anti-wear plate — the Monde YZJ310 metal-structure demolition shear has a main body made from high-strength structural steel and jaws fitted with replaceable anti-wear plate. This layered construction maintains cutting performance throughout the attachment's service life and reduces maintenance cost compared with shears with non-hardened monobloc jaws.
• Compatible with 12–35 tonne excavators — the Monde YZJ310 metal-structure demolition shear covers the medium and medium-heavy excavators currently used on industrial demolition sites in Romania. The 3,300 kg weight fits within the lifting capacities of 12–35 tonne excavators without compromising machine stability or overloading the arm joint.
• 60-month UZINEX warranty — spare parts for jaws and cylinders in stock in Iași, guaranteed 24–48 hour nationwide technical support.
Main applications of the Monde YZJ310 metal-structure demolition shear
Demolishing industrial halls with heavy steel structures is the reference application of the Monde YZJ310 metal-structure demolition shear. Decommissioned industrial platforms — production halls, warehouses, machine shops, pumping stations — have load-bearing structures made from HEA/HEB sections of 200–400 mm and bridge beams that require a shear with a large opening and high lateral force to be sectioned efficiently and reduced to transportable dimensions.
Processing large metal scrap is the second major application of the Monde YZJ310 metal-structure demolition shear. Authorised scrap-metal collection centres receive heavy batches from industrial demolition — groups of welded sections, long beams, massive machine frames — that smaller shears cannot process efficiently.
The Monde YZJ310 metal-structure demolition shear, with its 745 mm opening and 295 tonne lateral force, handles the flow of these heavy materials without prior manual pre-cutting.
Dismantling decommissioned heavy industrial machinery — hydraulic presses, mills, crushers, compressors, tanks and heat exchangers made from thick steel — requires frontal force for initial penetration and high lateral force to complete the cut.
The Monde YZJ310 metal-structure demolition shear covers this application with 122 tonnes of frontal force and 295 tonnes of lateral force — a combination sufficient for heavy-class structural steel machinery.
Demolishing port and riverside metal infrastructure — metal quays, support structures, decommissioned pontoons — is a niche application where the combination of low weight relative to cutting force and compatibility with the 12–35 tonne excavators currently used on such sites makes the Monde YZJ310 metal-structure demolition shear a practical solution compared with fixed cutting equipment.
The YZJ310 shear in the context of the full UZINEX shear range
UZINEX offers three types of hydraulic shears for excavators, each optimised for a different class of applications and tonnages. The right choice depends on the tonnage of the available excavator, the dimensions of the material to be processed and the priority among cutting force, cycle speed and attachment rotation.
The Monde JS-RT hydraulic shear (models JS280RT–JS480RT, 2,100–4,600 kg, 12–50 tonnes) is the multi-model solution for operators who need a wide range of sizing options — from 14–18 tonne excavators up to 28–39 tonnes — with main applications in medium and large demolition. The JS-RT range covers several tonnage classes with distinct models, in contrast to the specific nature of the YZJ310.
The Eagle Shear 310 (1,350 kg, 10–20 tonnes, 360° rotation, 8–12 second cycle) is the solution for smaller excavators that prioritise cycle speed and free rotation over maximum cutting force — metal recycling, vehicle dismantling, light selective demolition.
The Monde YZJ310 metal-structure demolition shear (3,300 kg, 12–35 tonnes, 295t lateral force, 745 mm opening) is the solution when raw cutting force and jaw opening are priorities — heavy industrial demolition, processing large metal scrap, dismantling massive machinery. Combined with a Monde DEHN quick coupler, it can be quickly switched with a bucket or another attachment for moving and sorting the material resulting from demolition.
Frequently asked questions about the YZJ310 metal-structure demolition shear
What hydraulic parameters does the Monde YZJ310 require?
The Monde YZJ310 metal-structure demolition shear operates with the standard auxiliary hydraulic circuit of 12–35 tonne excavators — no modifications to the hydraulic system are required. UZINEX checks the flow rate and pressure available on your specific model when quoting and confirms the compatibility of the metal-structure demolition shear before delivery.
The practical difference between 295t lateral force and 122t frontal?
The 295 tonne lateral force is exerted on the central zone of the jaw — the optimal cutting location for correctly gripped sections. The 122 tonne frontal force is exerted at the jaw tips and is used for initial penetration and for cutting pieces positioned toward the tip of the metal-structure demolition shear. The experienced operator positions the material in the maximum-force zone (lateral) for high-strength sections and uses the frontal force for initial penetration into compact structures.
Are the Monde YZJ310 jaws replaceable independently?
Yes — the anti-wear plates of the jaws of the Monde YZJ310 metal-structure demolition shear are replaceable without fully disassembling the attachment. UZINEX keeps spare parts in stock in Iași for immediate delivery, minimising machine downtime when the cutting components wear out.
