Buying a suitable excavator scrap shear can make your metal recycling work fast and easy. As a top factory, YG builds high-quality attachments to help you cut waste steel, rebar, and pipes. However, choosing the right model requires checking your project needs and excavator size. If the tool is too small, it cannot cut the metal. If it is too big, your excavator cannot lift it safely.

Match Your Tool Weight With Applied Excavator Weight
The first and most important step is to check the weight of your machine. Your excavator shear attachment must match your excavator perfectly to keep the work safe and stable. YG provides five different models for various machine sizes:
- Small Excavators (5 to 9 Tons): You should choose the YG-620 model. This attachment weighs 620 kg. It is light but very flexible for small demolition projects.
- Medium Excavators (10 to 19 Tons): The YG-1413 model is the best choice. It weighs 1413 kg and fits perfectly on standard mid-sized excavators.
- Standard Construction Excavators (20 to 25 Tons): The YG-2200 model is highly popular. It weighs 2200 kg and can handle daily heavy metal cutting.
- Large Excavators (28 to 35 Tons): You need the YG-2977 model. This attachment weighs 2977 kg and can cut thick scrap structures.
- Heavy-Duty Excavators (38 to 50 Tons): The YG-4052 model is the ultimate beast. It weighs 4052 kg and is designed for the toughest recycling yards.
If you put a heavy tool like YG-4052 on a 10-ton machine, the excavator will tip over. If you put a YG-620 on a 30-ton machine, the high hydraulic power of the excavator might break the tool. Always follow the weight guidelines to protect your workers and your machinery.
Understand Cutting Capabilities By Hydraulic Shears For Excavator
Different metal recycling jobs require different cutting forces and opening sizes. When searching for hydraulic shears for excavator, you must know the size and thickness of the scrap steel you want to cut. YG shears have three different cutting force areas on the blade: the bottom, the medium part, and the tip. The bottom area has the highest force because it is closest to the hydraulic cylinder.
Let us look closely at the parameters of YG models to see what they can do:
- YG-620: This model has a maximum open size of 334.4 mm and a width of 864 mm. The height is 1521 mm. It gives a bottom shear force of 81.2 tons, a medium force of 50.2 tons, and a tip force of 32.2 tons. The effective cutting depth is 286 mm. It is great for thin steel sheets and thin rebar.
- YG-1413: This model has a maximum open size of 540 mm and a width of 1175 mm. The height is 2050 mm. It offers a bottom shear force of 138.2 tons, a medium force of 80.2 tons, and a tip force of 53.2 tons. The effective cutting depth is 348 mm. It can cut standard steel pipes easily.
- YG-2200: This tool has a maximum open size of 500 mm and a width of 1370 mm. The height is 2380 mm. It delivers a bottom shear force of 171.2 tons, a medium force of 100.2 tons, and a tip force of 75.2 tons. The effective cutting depth is 486 mm. This model is perfect for general factory demolition.
- YG-2977: This heavy model has a maximum open size of 660 mm and a width of 1600 mm. The height is 2600 mm. It brings an amazing bottom shear force of 330.2 tons, a medium force of 189.2 tons, and a tip force of 127.2 tons. The effective cutting depth is 578 mm. It cuts heavy H-beams without any problem.
- YG-4052: This is our largest tool with a maximum open size of 801 mm and a width of 1700 mm. The height is 2700 mm. It provides a huge bottom shear force of 387.2 tons, a medium force of 218.2 tons, and a tip force of 147.2 tons. The effective cutting depth is 736 mm. Use this for thick ships, bridges, and large steel structures.

Check The Rotating Way For Easy Operation
The way your shear rotates affects how fast your operator can work. When you pick a metal shear excavator tool, you need to think about how you will position the blades around the scrap metal. YG offers two types of rotation systems depending on the model you select.
The YG-620 model uses a 360 collision rotation system. This means the tool rotates freely when it touches the ground or the metal structure. It is a simple mechanical design. It is very light, easy to maintain, and does not need extra hydraulic lines from your excavator. This makes it a very cost-effective choice for small contractors who do basic cleaning or minor dismantling tasks.
The larger models, including YG-1413, YG-2200, YG-2977, and YG-4052, use a full 360 hydraulic rotation system. This system connects directly to the hydraulic controls inside the cabin. The operator can push a button or use a joystick to spin the shear to any exact angle in the air. This gives perfect control and allows the operator to cut steel beams at high heights or inside narrow corners very quickly. If you run a busy scrap yard where time is money, the hydraulic rotation models will increase your daily production significantly.
Consider Working Pressure And Hydraulic System Compatibility
Your excavator has a specific hydraulic system that pumps oil at a certain pressure. Your new excavator scrap shear must match this pressure to work at full power. If your excavator hydraulic pressure is too low, the shear will not reach its maximum cutting force. If the pressure is too high, it could damage the seals inside the shear cylinder.
YG shears are designed to work with standard industrial pressures:
- The YG-620 model requires a working pressure of 235 Bar.
- The YG-1413 model requires a working pressure of 300 Bar.
- The YG-2200, YG-2977, and YG-4052 models all require a stable working pressure of 320 Bar.
Before you buy, please read your excavator manual or ask your mechanic to check the maximum pressure of the auxiliary hydraulic lines. YG can help you choose or adjust the valves to make sure our shear attaches to your machine smoothly without damaging any hydraulic parts.

Choose The Right Tool For Your Concrete And Rebar Demolition
If your daily work involves tearing down concrete buildings, you will find a lot of waste rebar hidden inside the concrete walls and pillars. You need an attachment that can handle both the crushing leftovers and the messy metal wires. A heavy-duty steel shear is the perfect partner for this job.
When picking a tool for rebar recycling, look at the effective shear depth and the opening size. For example, the YG-1413 has an opening size of 540 mm and an effective depth of 348 mm. This allows the operator to grab large chunks of concrete-covered rebar and cut through them in one single bite. For larger structural pillars found in industrial factories, upgrading to the YG-2977 with its 578 mm depth will allow your team to clear the site much faster.
Key Maintenance Tips For Your Hydraulic Shear Attachment
To make your tool last for many years, you must take care of it daily. Even the strongest steel shear will wear down if you do not maintain it correctly. Here are the most important things you should do:
- Grease the moving parts: Apply high-quality grease to all the rotation bearings and main pins every 4 to 8 hours of continuous work. This stops friction and prevents metal from rubbing against metal.
- Check blade tightness: The cutting blades have heavy bolts that hold them in place. Check these bolts every morning before you start the engine. Loose blades can cause bad cuts and damage the main structure.
- Rotate or change the blades: YG blades are designed with multiple cutting edges. When one side becomes dull, you can turn the blade around to use a fresh, sharp edge. This saves time and keeps your cutting force high.
- Watch the hydraulic oil: Keep your excavator hydraulic oil clean. Dirty oil carries small metal pieces that can scratch the big cylinder inside your scrap shear. Change your filters regularly.
