Bucket Cylinder for Kobelco Small Excavator SK60-C

Introduction

Definition

A bucket cylinder is a specially designed hydraulic cylinder used to control the movement of a bucket in heavy machinery such as excavators, backhoe loaders, and front loaders. Its primary function is to enable the bucket to lift, lower, and tilt, making it easier to handle various materials. In the hydraulic system, the bucket cylinder achieves precise control of the bucket’s movement through changes in hydraulic oil pressure, allowing the operator to efficiently handle heavy loads and adapt to complex working conditions and diverse operational requirements.

Характеристики

• High Strength and Durability: Typically made from high-strength steel or aluminum, it can withstand high pressure and heavy loads, adapting to harsh working environments, with a design that considers wear resistance and corrosion resistance, prolonging service life.
• Efficient Hydraulic Operations: Using hydraulic oil pressure to achieve smooth extension and retraction movement, it can quickly respond to control commands, providing powerful pushing and pulling force suitable for handling heavy loads and complex operational tasks.
• Various Types: Single-acting (hydraulic is used in one direction only) or double-acting (hydraulic is used in both directions) cylinders can be selected according to the needs to meet different operational requirements. Some models are telescopic, allowing for greater extension without increasing external dimensions, suitable for limited-space applications.
• Interchangeable: Our products can perfectly replace these hydraulic cylinders.
• Customization: We can produce this product according to customer specifications.

Applications

Bucket cylinders are widely used in various heavy machinery, including:

• Construction Equipment: In excavators, they are essential for digging, loading, and moving soil or debris. In backhoe loaders, the bucket cylinder helps with excavation and lifting.
• Agricultural Machinery: Used in front-end loaders, for excavating, lifting, and transporting soil, hay, and other materials.
• Excavators: The bucket cylinder achieves digging action by allowing the bucket to penetrate the soil.
• Front Loaders: In front-end loaders, they help with lifting and tipping goods effectively.

Design Considerations and Selection Criteria

Design Considerations

• Bearing Capacity: The cylinder should be designed to withstand the maximum load that it may encounter in operation.
• Sealing: Various sealing components, such as piston seals and rod seals, should be used to prevent fluid leakage.
• Durability: The cylinder should be designed with wear-resistant materials and surface treatments to extend its service life.
• Safety: The cylinder should be designed to prevent accidents, such as sudden drops or overloading, and should meet relevant safety standards.
• Maintainability: The cylinder should be designed to facilitate inspection, maintenance, and repair.

Selection Criteria

• Application: Proper selection of cylinder type should be based on the specific application and operational requirements.
• Size and Stroke: The cylinder’s bore diameter and stroke length should be selected based on the load capacity and operating conditions.
• Mounting Style: The cylinder mounting should be selected based on the mounting style of the machinery.
• Operating Pressure: The cylinder’s operating pressure should be within the specified range of the hydraulic system.
• Environmental Requirements: The cylinder should be selected based on the environmental requirements of the machinery, such as temperature, humidity, and corrosiveness.

Sealing and Lubrication

Various sealing components, such as piston seals and rod seals, should be used to prevent fluid leakage. The seals should be made of wear-resistant materials, such as polyurethane or nitrile rubber. The cylinder body and threaded end surface should be finely treated to improve wear resistance. Regularly adding an appropriate amount of hydraulic oil can effectively lubricate the cylinder and extend its service life.

Maintenance and Repair

Regular inspection, appropriate lubrication, seal replacement, and calibration checks are typical maintenance tasks. Proper installation, lubrication, and adjustment are essential to the cylinder’s performance and longevity. During installation, it is essential to align the cylinder correctly and use appropriate mounting brackets to secure the cylinder. We recommend specific inspection, repair, and replacement procedures, including rebuilding services and tips for increasing the cylinder’s lifespan.

Safety Considerations and Environmental Factors

When using hydraulic cylinders, safety precautions, such as wearing protective equipment and following safety guidelines, are essential. Environmental factors, such as temperature, humidity, corrosiveness, and cleanliness, should be considered when selecting the cylinder and the hydraulic system.

Common Problems and Troubleshooting

Common problems with hydraulic cylinders include fluid leakage, insufficient force, and erratic movement. Troubleshooting involves identifying the specific problem and its causes, such as worn seals or contaminated fluid, and taking appropriate corrective actions, such as seal replacement or fluid flushing. Regular preventive maintenance can help minimize such problems.
