Bucket Cylinder For Kobelco Small Excavator SK70SR-2

Introduction

The bucket cylinder, also known as the dipper or arm cylinder, is a hydraulic cylinder that is specifically designed to control the movement of the bucket in heavy machinery such as excavators, backhoes, and front loaders. Its main function is to enable the bucket to lift, lower, and tilt, allowing for easy material handling tasks.

Features

• High strength and durability: typically made of high-strength steel or aluminum, it can withstand high pressure and heavy loads, adapting to harsh working environments. The design considers wear resistance and corrosion resistance, extending its service life.
• Efficient hydraulic operation: using the pressure of hydraulic oil to achieve smooth extension and contraction, it can quickly respond to control commands, providing strong pushing and pulling force, suitable for handling heavy objects and complex tasks.
• Various types: single-acting (hydraulic is used in only one direction) or double-acting (hydraulic is used in both directions) cylinders can be selected according to needs to meet different operating requirements. Some models are telescopic, allowing for greater expansion without increasing external dimensions, suitable for applications with limited space.
• Replaceable product: our product can perfectly replace these hydraulic cylinders.

Applications

The bucket cylinder is widely used in various heavy machinery such as:

• Construction equipment: found in excavators, they are essential for digging, loading, and moving soil or debris. In backhoes, the bucket cylinder helps with both digging and lifting.
• Agricultural machinery: used for front-end loaders, for scooping, lifting, and transporting soil, hay, and other materials.
• Excavators: the bucket cylinder achieves the digging action by allowing the bucket to penetrate the soil.
• Front loaders: in front loaders, they help to lift and tilt the cargo effectively.

Design Considerations and Selection Criteria

When choosing and designing the bucket cylinder, it is necessary to consider factors such as bearing capacity, sealing, durability, safety, and maintainability.

• Bearing capacity: the cylinder must be able to withstand high pressure and heavy loads.
• Sealing: various types of seals, such as piston seals and rod seals, should be used to ensure no oil leakage.
• Durability: the cylinder body and thread end surface should be finely processed to improve abrasion resistance.
• Safety: the cylinder must have enough strength to withstand external forces and prevent accidents.
• Maintainability: regular maintenance and inspection are required to prevent malfunctions and ensure the cylinder's longevity.

Sealing and Lubrication

The bucket cylinder uses various seals, such as piston seals and rod seals, made of wear-resistant materials such as polyurethane and nitrile rubber to ensure no oil leakage. The cylinder body and thread end surface are finely processed to improve abrasion resistance. Regular maintenance is required to add suitable amounts of hydraulic oil to lubricate the cylinder.

Maintenance and Repair

Regular inspection and preventive maintenance are required to ensure the longevity of the bucket cylinder. The following three common maintenance tasks are necessary:

• Regular inspection: check for oil leakage, deformation, and damage to ensure the cylinder is functioning properly.
• Appropriate lubrication: add suitable amounts of hydraulic oil to lubricate the cylinder regularly to maintain its smooth operation.
• Seal replacement and calibration check: replace worn-out seals and perform a calibration check to ensure the cylinder functions properly.

Proper installation is also crucial, offering correct alignment guidance and recommending the use of appropriate installation brackets to secure the cylinder. We also provide replacement parts and rebuilding services to improve the cylinder's longevity.

Safety and Environmental Considerations

When using the bucket cylinder, it is important to follow safety precautions to prevent accidents. Proper disposal of used hydraulic oil is also necessary to avoid any environmental harm.

Troubleshooting and Common Problems

Common problems with the bucket cylinder include oil leakage, deformation, and damage. It is important to perform regular inspections and preventive maintenance to prevent these issues. Troubleshooting tips and solutions are available to help diagnose and resolve problems, as well as preventive measures to minimize potential issues.
