Excavators use a variety of bolts for assembly, attachment, and structural purposes. The types and sizes of bolts used can vary depending on the specific model and manufacturer of the excavator. Here are some common types of bolts used in excavators:
1. Hex Head Bolts: These bolts have a hexagonal head and are tightened with a wrench or socket. They are commonly used for general assembly and securing components in excavators.
2. Track Bolts: Excavators have track systems that require track bolts for attaching the track shoes to the track chains. These bolts are typically larger and stronger to withstand the heavy loads and vibrations.
3. Bucket Teeth Bolts: Excavator buckets are equipped with teeth for digging and scooping. Bucket teeth bolts are used to secure the teeth onto the bucket, allowing for easy replacement when they wear out.
4. Linkage Bolts: Excavator linkages, such as the arm and boom, are connected using linkage bolts. These bolts are designed to handle the dynamic forces and movements of the excavator during operation.
5. Sprocket Bolts: Excavator sprockets, which engage with the track chains, are secured using sprocket bolts. These bolts ensure the proper alignment and operation of the track system.
6. Guard Bolts: Excavators often have guards or protective plates to shield vulnerable components. Guard bolts are used to attach these protective elements, providing additional safety and durability.
7. Cab Bolts: The cab of an excavator is mounted on the mainframe using cab bolts. These bolts ensure the stability and structural integrity of the operator's compartment.
8. Plow Bolts: Plow bolts, also known as carriage bolts, have a flat, countersunk head and a square or ribbed neck. They are commonly used for attaching cutting edges, wear plates, and other components to the bucket or blade of an excavator.
9. Flange Bolts: Flange bolts have a built-in washer-like flange beneath the head, which distributes the load and provides a larger bearing surface. They are often used in areas where there is a need for a wider load-bearing surface or where vibration resistance is required.
10. Shoulder Bolts: Shoulder bolts, also known as shoulder screws or stripper bolts, have a cylindrical shoulder between the head and the threaded portion. They are commonly used in applications where precise alignment or rotational movement is required, such as attaching hydraulic cylinders or pivot points.
11. Hex Flange Bolts: Hex flange bolts have a flange integrated into the hexagonal head. The flange eliminates the need for a separate washer and provides a larger load-bearing surface. They are commonly used in areas where a wide bearing surface is required, such as attaching engine components or mounting brackets.
12. Tension Control Bolts: Tension control bolts, also known as TC bolts or twist-off bolts, have a specialized design that allows for controlled tensioning during installation. They are often used in critical connections that require accurate and consistent bolt tension, such as structural components or heavy machinery attachments.
13. Socket Head Cap Bolts: Socket head cap bolts have a cylindrical head with a recessed hexagonal socket. They are often used in applications where a low-profile bolt head is required, or where access is limited and a socket wrench is needed for tightening.
14. Flange Head Bolts: Flange head bolts have a flange integrated into the bolt head, which eliminates the need for a separate washer. They provide a larger bearing surface and are often used in applications where increased stability and load distribution are required.
15. Track Shoe Bolts: Track shoe bolts are specifically designed for attaching the track shoes to the track chains of an excavator. These bolts are typically larger and stronger to withstand the heavy loads and vibrations encountered during operation.
16. Tooth Bolts: Tooth bolts are used to secure the bucket teeth onto the excavator bucket. They are designed to provide a strong and secure attachment, allowing for easy replacement when the teeth wear out.
17. Guardrail Bolts: Guardrail bolts are used to attach guardrails and protective plates to the excavator. They help protect sensitive components from damage and ensure operator safety.
18. Pin Bolts: Pin bolts, also known as hinge bolts or pivot bolts, are used to secure the pins and bushings in excavator linkages. These bolts play a crucial role in maintaining the structural integrity and proper functioning of the excavator's moving parts.
19. Mounting Bolts: Mounting bolts are used to secure various components and attachments to the excavator, such as hydraulic breakers, thumbs, or quick couplers. These bolts provide a secure connection and allow for easy installation and removal of attachments.
20. Shoulder Eye Bolts: Shoulder eye bolts have a threaded shank with a shoulder or eyelet at one end. They are commonly used for lifting or rigging applications, providing a secure anchor point for attaching slings or cables.
21. Stud Bolts: Stud bolts are threaded rods with threads on both ends. They are often used in applications where a nut is required on both ends, such as securing flanges or other components that need to be joined together.
22. J-Bolts: J-bolts have a J-shaped bend at one end, which provides a hook-like structure. They are commonly used for anchoring purposes, such as securing heavy equipment or structures to concrete foundations.
23. U-Bolts: U-bolts have a U-shaped bend with threaded ends. They are commonly used for securing pipes, tubes, or cables to structures or supports.
24. Shoulder Bolts: Shoulder bolts, also known as shoulder screws or stripper bolts, have a cylindrical shoulder between the head and the threaded portion. They are often used in applications where precise alignment or rotational movement is required, such as attaching hydraulic cylinders or pivot points.
25. T-Bolts: T-bolts have a T-shaped head, which provides a stable anchor point. They are commonly used in T-slot tracks or profiles for securing components or accessories.
26. Anchor Bolts: Anchor bolts are used to secure heavy equipment or structures to concrete or masonry surfaces. They often have an L-shaped or J-shaped end that is embedded into the concrete or masonry for added stability.
27. Eye Bolts: Eye bolts have a looped or circular eyelet at one end, providing a secure anchor point for attaching ropes, cables, or hooks. They are commonly used for lifting or rigging applications.
28. Clevis Bolts: Clevis bolts have a flat, cylindrical head and a threaded shank with a hole through the end. They are commonly used in applications where a removable connection point is required, such as attaching hydraulic cylinders or connecting linkage components.
29. Tension Control Bolts: Tension control bolts, also known as TC bolts or twist-off bolts, have a specialized design that allows for controlled tensioning during installation. They are often used in critical connections that require accurate and consistent bolt tension, such as structural components or heavy machinery attachments.
30. Shoulder Eye Bolts: Shoulder eye bolts have a threaded shank with a shoulder or eyelet at one end. They are commonly used for lifting or rigging applications, providing a secure anchor point for attaching slings or cables.
31. Hex Socket Bolts: Hex socket bolts, also known as Allen bolts or socket head bolts, have a cylindrical head with a recessed hexagonal socket. They are tightened using an Allen wrench or hex key and are commonly used in applications where a low-profile bolt head is required.
32. Foundation Bolts: Foundation bolts, also known as anchor bolts, are used to secure the base of heavy equipment or structures to concrete foundations. They often have an L-shaped or J-shaped end that is embedded into the concrete for added stability.
33. Step Bolts: Step bolts, also known as ladder rung bolts, have a flat, wide head with gripping ridges or steps. They are commonly used in applications where a secure foothold or ladder rung is required, such as on excavator access platforms or steps.
34. Hanger Bolts: Hanger bolts have a threaded end on one side and a wood screw thread on the other. They are commonly used for attaching components to wooden surfaces or structures.
It's important to note that the specific types and sizes of bolts used in excavators can vary depending on the manufacturer, model, and application. It's recommended to refer to the manufacturer's specifications or consult with a reputable supplier to ensure the correct selection of bolts for your excavator.
