Bucket Cylinder For Doosan Large Excavator DH420LC-7

Introduction

The bucket cylinder for Doosan large excavator DH420LC-7 is a specialized hydraulic cylinder designed to control the movement of the bucket in heavy-duty machinery such as excavators, backhoes, and loaders. Its main function is to enable the bucket to lift, lower, and tilt, facilitating various material handling tasks. In hydraulic systems, the bucket cylinder achieves precise control of the bucket movement through the pressure change of hydraulic oil, enabling operators to efficiently handle heavy loads and adapt to complex working environments and diverse job requirements.

Features

• High strength and durability: usually made of high-strength steel or aluminum, able to withstand high pressure and heavy loads, adaptable to harsh working environments, designed with wear resistance and corrosion resistance in mind, extending the service life.
• Efficient hydraulic operation: utilizing the pressure of hydraulic oil to achieve smooth extension and retraction actions, able to respond quickly to control commands, providing powerful pushing and pulling force, suitable for handling heavy loads and complex job tasks.
• Diverse types: single-acting (using hydraulic in one direction only) or double-acting (using hydraulic in two directions) cylinders can be chosen as per the requirements to meet different operational needs, some models are telescopic, allowing greater extension without increasing the external dimension, suitable for space-limited applications.
• Replaceable with other hydraulic cylinders: our product can perfectly replace these hydraulic cylinders.

Applications

Bucket cylinders are widely used in various heavy-duty machinery, including but not limited to:

• Construction equipment: in excavators, they are critical for digging, loading, and moving soil or debris. In backhoes, the bucket cylinder helps with both digging and lifting.
• Agricultural machinery: used in front-end loaders for scooping, lifting, and transporting soil, hay, and other materials.
• Excavators: the bucket cylinder enables digging action by allowing the bucket to penetrate the soil.
• Loaders: in front loaders, they help with lifting and dumping goods effectively.

Each application is elaborated below:

Construction equipment

In excavators, bucket cylinders are essential for digging, loading, and moving soil or debris. In backhoes, they help with both digging and lifting. The bucket cylinder’s strength and durability enable it to withstand harsh working conditions, while its efficient hydraulic operation allows for fast and precise movements, improving work efficiency and productivity.

Agricultural machinery

Bucket cylinders are extensively used in front-end loaders to scoop, lift, and transport soil, hay, and other materials. This equipment is critical for agricultural work as it enables quick and efficient handling of crops and livestock feed, saving time and labor costs.

Excavators

The bucket cylinder is a critical component in excavators, enabling the bucket to penetrate the soil for efficient digging. The cylinder’s strength and durability, combined with its efficient hydraulic operation, provide the necessary power to excavate even the toughest terrain quickly and efficiently.

Loaders

In front loaders, bucket cylinders help with lifting and dumping goods effectively. The cylinder’s efficient hydraulic operation allows for smooth and precise movements, ensuring that goods are transported safely without damage.

Design Considerations and Selection Criteria

When designing and selecting bucket cylinders, various factors need to be considered, including:

• Bearing capacity: the bucket cylinder must be strong enough to support the weight of the load it carries.
• Sealing capability: the cylinder must have an effective sealing system to prevent hydraulic leaks and contamination, ensuring proper functioning.
• Durability: the cylinder must be durable enough to withstand harsh working environments, reducing maintenance needs and costs.
• Safety: the cylinder must be designed with safety features that ensure safe operation and prevent accidents.
• Maintainability: the cylinder must be easy to maintain, allowing for quick repairs and replacement of faulty parts when needed.

Our bucket cylinders are designed and manufactured to meet these criteria. We use high-quality materials and advanced manufacturing techniques to produce cylinders that are strong, durable, and reliable.

Sealing and Lubrication

Our bucket cylinders use various seals, such as piston seals and rod seals, made of wear-resistant materials such as polyurethane and nitrile rubber. The cylinder body and threaded end surface are finely processed to improve wear resistance. Proper lubrication is also crucial to ensure the cylinder’s proper functioning, and we recommend using the appropriate amount of hydraulic oil regularly.

Maintenance and Repair

Regular maintenance and appropriate repair measures can extend the bucket cylinder’s service life and ensure its efficient operation. Common maintenance tasks include regular inspection, lubrication, seal replacement, and calibration checks. Proper installation, lubrication, and adjustment are essential to ensure the cylinder’s safe and efficient operation. We recommend using appropriate installation brackets to secure the cylinder, and following our recommended inspection, repair, and replacement procedures to ensure the best results.

Safety and Environmental Considerations

Bucket cylinders must be used with appropriate safety measures to prevent accidents and injuries. Users must follow proper operating procedures and ensure that the equipment is in good condition before use. Environmental considerations include proper disposal of used hydraulic oil and used seals, to avoid contamination of soil and water sources.

Troubleshooting and Common Problems

Common problems with bucket cylinders include hydraulic leakage, insufficient power, and slow movement. These issues can be caused by various factors such as worn seals, damaged rods or pistons, and insufficient oil pressure. Proper inspection and diagnosis are necessary to determine the root cause of the problem and apply the appropriate repair measures. We provide troubleshooting tips and repair solutions to help users diagnose and solve problems effectively.
