An excavator dipper arm, also known as a stick or boom arm, is a structural component of an excavator that extends from the machine's base to support the bucket. It connects the boom (the main arm of the excavator) to the bucket linkage, allowing for controlled movement and positioning of the bucket during excavation operations.
The dipper arm is typically made of high-strength steel and consists of multiple sections or segments that can be extended or retracted, providing reach and versatility to the excavator. The number and length of the segments can vary depending on the size and design of the excavator.
The dipper arm is connected to the boom through pivot points and hydraulic cylinders that enable the arm's movement. By extending or retracting the dipper arm, the operator can adjust the reach and depth of the bucket, allowing for digging, loading, and material handling tasks.
Excavator dipper arms come in various sizes and configurations to accommodate different excavator models and applications. They are designed to withstand the forces and stresses encountered during excavation operations and provide stability and control for efficient and safe digging.
Types of excavator dipper arm
Excavator dipper arms come in various types and configurations to suit different excavator models and specific applications. Here are some common types of excavator dipper arms:
1. Monoblock Dipper Arm: Monoblock dipper arms consist of a single, solid structure without any joints or sections. They are typically used in smaller excavators and are known for their simplicity and durability.
2. Two-Piece Dipper Arm: Two-piece dipper arms are composed of two sections that are connected with a hinge or pin joint. This design allows for greater flexibility and reach compared to monoblock arms. Two-piece dipper arms are commonly found in mid-sized excavators.
3. Three-Piece Dipper Arm: Three-piece dipper arms consist of three sections connected by two hinge or pin joints. This type of dipper arm offers even greater reach and flexibility, making it suitable for larger excavators and applications that require extended reach.
4. Telescopic Dipper Arm: Telescopic dipper arms can extend and retract in a telescoping manner, providing adjustable reach capabilities. They are composed of multiple nested sections that can slide in and out, allowing the operator to adapt the arm length as needed. Telescopic dipper arms are commonly found in specialized excavators used for tasks such as pipe laying or working in confined spaces.
The specific types of dipper arms available may vary depending on the excavator manufacturer, model, and intended application. It's important to consider factors such as reach, digging depth, lifting capacity, and the specific tasks you need the excavator for when selecting the appropriate dipper arm type for your requirements.
Price ranges for different excavator dipper arm
It's always best to consult with manufacturers, dealers, or suppliers for specific and up-to-date pricing information. Here are some rough estimates:
1. Monoblock Dipper Arm: $1,000 to $5,000
2. Two-Piece Dipper Arm: $2,500 to $10,000
3. Three-Piece Dipper Arm: $5,000 to $20,000
4. Telescopic Dipper Arm: $10,000 to $50,000
If you're looking to equip an excavator with a specific type of dipper arm, it's recommended to consult with the excavator manufacturer, authorized excavator parts suppliers, or industry experts to determine the best option for your specific excavator model and operational needs.
