Types of Hydraulic Shears for Excavators

Hydraulic shears for excavator are attachments used in excavators to cut thick stainless steel, iron, metal plates, pipelines, branches and other materials. There are different types of hydraulic excavator shears based on their application and design.

• Universal shears: These types of shears are suitable for cutting various materials such as metal, PVC, branches and more. They are designed to handle different types of materials without needing frequent attachments or adjustments.
• Demolition shears: This shear is designed with wide blades curved inward for demolition projects. They can make short work of thin to medium grade metals, including iron, steel, and railway tracks, without getting the edges blunt. Also, they are suitable for demolishing buildings, cutting metals, pipes and concrete structures. Their features include strong blades that could make cuts easily in dense metals and structures and tipbooms that provide better access to hard-to-reach areas. The speed and power of demolition excavator shears are unmatched by portable cutting tools.
• Metal shears: These hydraulic excavator shears are explicitly designed to cut through dense metals such as cast iron using an excavator as a power source. The blades are usually made from high-tensile steel, which gives them the edge and strength needed to execute cuts precisely. They come in various sizes to fit excavators of different capacities. The shears are easy to install using quick couplers and are excavator powered, meaning there is no need for an external power source or hydraulic pump.
• Hydraulic container shears: Container hydraulic shears are used for cutting open bulk commodities or cement containers. They could be mobile or static in form, mounted on an excavator, loader, or fork, according to the customers' requirements. The shear is classified into two types as per its operation mode: the single-cylinder hydraulic shear and the double-cylinder hydraulic shear. The single has a cylinder and can also be called a mobile container shear. Meanwhile, the double has two basic parts: the static and moving ones, thereby featuring a more efficient speed and a better safety grade.
• Pipe shears: These hydraulic pipe shears are tailored explicitly for cutting through pipes (plastic, metal, or otherwise). They leverage the power of the excavator to make swift, clean cuts without leaving jagged edges. When fitted with an excavator, they can cut large-diameter pipes in difficult-to-reach locations as construction crews do not have to worry about the pipe getting stuck in the blade.
• Crop shears: Also known as hydraulic cutting shears or hydraulic crop/metal shears, they are heavy-duty cutting tools powered by hydraulics. They are explicitly designed to cut through thick metal plates, sheets, and strips, including steel, copper, and aluminum, using high-pressure hydraulic force. The cropping action involves the hydraulic shears' blades slicing through the metal after being pressed together with hydraulic power. Crop shears are not limited to metals. They can cut through plastic and rubber if the blade's material and design suit these materials.

Specifications and maintenance of hydraulic shears for excavator

Specifications

• Type of Material: They can cut a wide range of metals, including Reinforced Iron, Angle Steel, Pipe, I-steel, H-steel, T-steel, etc., and even Non-Metal materials like Wood and Plastic.
• Operating System: Managed by hydraulic systems, some may have electric controls, remote controls, etc.
• Cutting Method:A combination of shear cutting, crush cutting, and other methods, like crushing and cutting simultaneously.
• Excavator Size: From small (1-6 tons) to large (over 30 tons) excavator adapters.
• Cutting Force: 60-150 tons of cutting force is common, but it can go up to 60,000 tons for more giant excavators.
• Cutting Range: This includes the size of the blades and mouth opening. The shears have to be the right size for the material to be cut.
• Blades: They are made of high-strength alloy steel and are usually double-edged (sharper on one side and more durable on the other) that can be replaced after a while.
• Rotating head: Sometimes called a rotating shears, can rotate up to 360°. It allows it to position itself accurately for cutting. The angle varies with different models.
• Weight: They typically weigh between 100 kg and 3000 kg, depending on the size and capacity.

Maintenance tips

• Inspection: Frequently inspect the hydraulic circuit and remove any dust or attachments in the cleaning part. The operator should examine bolt fastening, gear wear, electrical lines, and blade edges to discover and fix the problems early.
• Pay attention to hydraulic oil and blade grease. The hydraulic oil should be contamination-free and suitable for the machine, while the shear should be sufficiently lubricated to reduce friction and avoid excessive engine load and oil consumption.
• Repair and adjustment: Replace the damaged oil pipe. Oil leakage not only damages the machine but also poses safety risks. Damage to the blade edge directly affects operation; still, other parts can usually be repaired by adjusting bolts, gears, etc.
• Store it in a dry and ventilated place, away from direct sunlight and rain. In case of exposure to water, dry the machine immediately to avoid rust damage. Keep it away from flammable and explosive materials, with at least 2 meters of distance from other items, so it is easier to inspect and service.

How to choose hydraulic shears for excavator

When purchasing a hydraulic shear for an excavator, several factors need to be considered to ensure that the correct attachment is selected for both operational and safety purposes.

• Match Hydraulic Shears with the Excavator

  It is crucial to match the shear's size and weight to the excavator's working weight. A loader that is an inappropriate weight could put excessive pressure on the excavator's arm, hydraulic system, and structural integrity, leading to premature wear or damage. Alternatively, if the shear is too heavy, it could hinder the excavator's stability and mobility.

• Operator Training and Experience

  Also, consider the operator's training and experience. Selecting attachments that match the operator's skill level can help avoid accidents and ensure proper maintenance.

• Shear Features and Attachment Options

  Many types of hydraulic excavator shears are available, including multi-shears, concrete and steel shears, and specialized variants like cable shears or universal shears. Examine the features and attachment options of each shear before purchasing. Consider the shear's features, like interchangeable jaws, if operational flexibility is essential.

• Environment and Worksite Safety

  The worksite environment should be considered as well. If the task involves cutting materials in a confined space, consider a shear with a blade configuration that prevents projectile risks. For operators handling different materials, look for a shear with replaceable jaws that allow quick jaw changes and adapt to various tasks.

• Quality and Reliability

  Before purchase, examine the shear's quality and reliability. Do preliminary research and read reviews to gauge the performance of different shears. A well-maintained hydraulic shear excavator ensures operational efficiency and safety.
