In the demolition and recycling industry, a hydraulic scrap shear for an excavator is a specialized attachment that converts your excavator into a high-performance steel cutting machine. The current global boom in infrastructure renewal, bridge dismantling, and scrap metal recycling has driven a surge in demand for reliable cutting attachments. YG Machinery has launched five vertical hydraulic scrap shears for excavators: the YG-620, YG-1413, YG-2200, YG-2977, and YG-4052. They feature 360° rotation (hydraulic or collision), double-cylinder cutting force, IP54-rated durability, high efficiency, and easy mounting on 5-50 ton excavators. With extremely low maintenance requirements, significant long-term operating cost advantages, corrosion-resistant steel bodies, and core components from top-tier brands, they are suitable for cutting needs in different scenarios, from scrap rebar processing to structural steel demolition. They are a highly reliable choice for contractors, scrap yards, and demolition crews.
But with five models and many ordinary shears on the market, how do you choose the right one? In this head-to-head comparison, we pit YG Machinery’s five popular hydraulic scrap shears against average alternatives, focusing on cutting force, jaw opening, rotation system, and excavator compatibility.
Technical Specifications Of YG Hydraulic Cutting Shears
All five models are hydraulic-driven attachments designed for cutting scrap rebar, structural steel, pipes, and concrete reinforcement. Below are the core parameters.

All models feature a double-cylinder design for balanced cutting force. The larger four models include full 360° hydraulic rotation, while the YG-620 uses a collision-based rotation system (still 360°).
Comparison Of The YG-type Shearing Machine And The Ordinary Shearing Machine
Many buyers searching for a hydraulic scrap shear for an excavator get tempted by cheap, single-cylinder shears with vague specs. Let us break down three critical dimensions across YG’s lineup and compare them to ordinary alternatives.
Cutting Force Distribution (Bottom, Medium, Tip): Ordinary shears often advertise only the bottom shear force (the strongest point), hiding weak tip performance. YG provides transparent numbers for all three positions. For example, the YG-4052 delivers 387.2T at the bottom, 218.2T in the middle, and still 147.2T at the tip – enough to cut thick rebar even in tight spaces. Cheap shears may have 150T at the bottom but only 30T at the tip, making precision cuts impossible.
Jaw Opening and Shear Depth: A wider opening lets you grab larger steel sections. The YG-620 opens 334mm – suitable for rebar and small beams. The YG-4052 opens 801mm – wide enough for structural steel columns. Ordinary shears in the same weight class often have 20-30% smaller openings. Shear depth follows the same pattern: YG-4052 cuts 736mm deep, while generic 4-ton shears rarely exceed 500mm.
Rotation System and Maneuverability: The YG-620 uses collision rotation (mechanical stops) – reliable and cost-effective for 5-9T carriers. All larger YG models feature full 360° hydraulic rotation, allowing continuous rotation without repositioning the excavator. Ordinary shears at similar prices often use limited rotation (180° or 270°) or require an extra hydraulic circuit that many excavators lack. YG’s hydraulic rotation works with standard auxiliary lines.
Excavator Compatibility and Structural Integrity: Each YG model is precisely matched to an excavator weight range. The YG-620 fits 5-9T carriers; the YG-4052 fits 38-50T machines. This ensures the shear does not overload the boom or underperform due to low hydraulic flow. Ordinary shears often use a “one-size-fits-most” approach, leading to cracked mounts or slow cycle times.
Core Advantages Of YG’s Hydraulic Scrap Shears Over Competitors
Why do professional demolition contractors choose YG’s scrap rebar cutting attachment? Four unbeatable strengths.
Exceptional Cutting Force Across the Entire Blade: The double cylinder design and optimized jaw geometry deliver high force from tip to bottom. You can cut dense rebar bundles, steel pipes, and even light structural beams without repositioning the material. This cuts cycle time by up to 40% compared to single-cylinder shears.
360° Hydraulic Rotation (Except YG-620): Full rotation means you can approach the scrap from any angle – under debris, against a wall, or inside a concrete structure. The rotation motor is protected inside the housing, reducing damage from falling material. Ordinary shears with external rotation motors often fail after a few months of heavy use.
Heavy-Duty Construction: All YG shears use high-strength steel for the housing and replaceable blades made from wear-resistant alloy steel. Blades can be resharpened multiple times. The pivot pins are induction-hardened and greasefed, preventing premature wear.
Easy Installation and Wide Adaptability: Each shear comes with a mounting bracket that fits most excavator brands. The hydraulic hoses use standard couplings. Remote installation guidance is free, and YG can arrange on-site support if needed.
Which Hydraulic Scrap Shear Model Should You Choose?
Based on our comparison, here is the straightforward advice.
Choose the YG-620 if: Your excavator is between 5 and 9 tons. You mainly cut rebar, light pipes, and thin steel sections. You want a compact, affordable shear with 360° collision rotation. Ideal for urban demolition and small recycling yards.
Choose the YG-1413 if: Your excavator is 10-19 tons. You need 138T bottom force and 540mm jaw opening. Hydraulic 360° rotation gives you full maneuverability. Perfect for general demolition and scrap processing.
Choose the YG-2200 if: Your excavator is 20-25 tons. You handle medium structural steel and heavy rebar bundles. With 171T bottom force and 500mm opening, this is the most popular model for medium-sized contractors.
Choose the YG-2977 or YG-4052 if: Your excavator is 28-50 tons. You process thick steel beams, bridge dismantling waste, or heavy industrial scrap. The YG-4052 delivers 387T bottom force – enough to cut through solid steel sections. These models also have the deepest shear depth (up to 736mm), letting you bite into large piles.
Avoid ordinary shears if: They do not provide full cutting force tables, have limited rotation, or are not matched to your excavator’s weight. A mismatched shear will damage your machine or fail to cut efficiently.
