PC300用ショベルブーム

At XINGCHUANG, we manufacture excavator structural parts for replacement and project-specific requirements. Our Excavator Boom for PC300 is designed around the stated PC300 application, with material selection, reinforced stress areas, welding inspection, and surface protection considered during production. We hold CE certification and can discuss technical requirements before confirming an order.

Check Fitment Before Replacement

A Excavator Boom for PC300 is a major load-bearing structure connecting the excavator's upper body to the working equipment. Even small differences in pin spacing, mounting width, or cylinder connection points can create installation problems. Before ordering a replacement, we recommend confirming the exact machine model, serial number, production series, and existing boom configuration.

Confirm the Mounting Points

Check the dimensions and positions of the boom foot pins, arm cylinder mounting points, boom cylinder connections, and related brackets. Buyers should also compare the overall length and clearance with the original component. These details help determine whether the replacement can be installed without modifications.

Review the Hydraulic Layout

Hydraulic pipe routing and attachment details may vary between machine versions or previous modifications. We recommend checking the existing line arrangement, clamps, brackets, and connection locations before production. Final compatibility should be confirmed against the specific PC300 configuration rather than assuming every machine in the series uses identical dimensions.

Structural Design for Heavy Work

Excavator booms experience repeated bending loads and stress around pin joints and cylinder mounts. Mining, quarrying, and high-cycle earthmoving can increase fatigue demands, particularly when the machine works with heavy attachments or in abrasive conditions.

High-Strength Steel Plate

The supplied configuration uses Q355NM high-strength steel for the main structure. Material suitability depends on the required mechanical properties, plate thickness, fabrication process, and working environment. We recommend confirming the material grade and relevant documentation in the order specification when traceability is required.

Reinforce Critical Stress Areas

The boom tube, hinge seats, and internal reinforcing plates require careful structural design because loads concentrate around joints and connection points. Our manufacturing approach focuses on suitable reinforcement and consistent fabrication to help the component withstand repeated operating loads. Reinforcement details should be designed for the intended machine and should not interfere with pin movement, cylinder geometry, or service access.

Protect Exposed Surfaces

Outdoor machinery is exposed to moisture, dust, mud, and changing temperatures. The supplied production process includes surface preparation and anti-corrosion coating to help protect exposed steel. Regular inspection and timely repair of damaged coating remain important, especially when equipment operates in wet or corrosive environments.

Inspect Welding and Fabrication Quality

Weld quality is a key consideration when purchasing a replacement boom. Poor weld preparation, inconsistent welding, or inadequate inspection can increase the risk of defects in highly stressed areas. Buyers should ask how critical joints are fabricated and what inspection records are available for the finished component.

Welding Process Control

Our supplied manufacturing information specifies automatic robotic multi-layer welding. Consistent preparation, welding parameters, and workmanship help support repeatable fabrication quality. The appropriate welding procedure depends on material thickness, joint design, and production requirements.

Inspection of Critical Joints

Inspection methods should be selected according to the joint design and applicable quality requirements. Where specified, non-destructive testing can help identify certain surface or internal defects. Buyers with project-specific inspection requirements should confirm the method, acceptance criteria, and documentation before placing an order.

Final Dimensional Checks

Before installation, the main mounting dimensions and pin locations should be checked against the approved drawing. We recommend requesting dimensional inspection records and confirming that the delivered boom matches the agreed configuration, especially for replacement projects where downtime is costly.

Performance in Different Work Sites

Mining and Quarry Operations

In open-pit mining and quarrying, the Excavator Boom for PC300 is exposed to repeated digging loads and potential shock loading. Correct machine operation, suitable attachment selection, and regular inspection are important alongside structural quality. The excavator should remain within the manufacturer's operating limits.

Road and Infrastructure Construction

Road building, bridge foundations, earthmoving, and site preparation often require repeated boom movement throughout long shifts. Correct geometry and fitment help maintain the intended working range and avoid unnecessary stress caused by misaligned connections.

River and General Earthworks

River regulation, bank excavation, and general earthworks may expose structural components to moisture and abrasive material. Surface maintenance, pin-joint inspection, and monitoring for cracks or deformation can help identify problems before they lead to extended equipment downtime.

Customer Project: Granite Mining in Malaysia

Replacement Supply for a Sarawak Site

According to the project information provided to us, XINGCHUANG supplied 20 customized PC300 excavator booms in 2025 for an open-pit granite mining project in Sarawak, Malaysia. The customer reported that the original booms had experienced deformation, cracking, and heavy-load performance concerns, leading to maintenance interruptions.

Reported Operating Results

After the replacement booms were installed, the supplied case report states that the equipment operated for six months without reported failure and that maintenance frequency decreased by 80%. These figures describe the reported project and are not a guarantee of the same result under different operating conditions. Actual service life depends on machine condition, workload, operator practices, maintenance, and installation quality.

We recommend discussing the intended duty cycle, material handling conditions, and inspection requirements before selecting a replacement for similar mining projects.

Product Specifications

The following table summarizes the supplied configuration. Please confirm the exact model, dimensions, and technical documents for your machine before ordering.

Customization and Delivery Support

Replacement requirements can vary according to machine version, previous repairs, and the working environment. We can discuss customized structural details and batch supply after reviewing the application and approved drawings.

To reduce delays, we recommend providing the machine serial number, existing boom photographs, mounting dimensions, pin diameters, cylinder connection details, and any available original part number. If the boom has been modified previously, please include those details so the replacement can be assessed against the actual machine.

Delivery schedules depend on stock status, material preparation, drawing approval, production requirements, and inspection arrangements. We confirm lead time after the configuration and order details have been reviewed rather than applying one delivery estimate to every order.

Frequently Asked Questions

What information helps identify the correct PC300 boom version?

Please provide the machine serial number, production year if available, model details, original part number, and clear photographs of the boom and mounting points. These details help distinguish between configurations and reduce the risk of ordering an incompatible component.

Can I install the replacement if the original boom has been modified?

Not without checking the modifications first. Changes to mounting brackets, pin locations, cylinder connections, or hydraulic routing can affect fitment. Share the modified dimensions and photographs before production so the replacement requirements can be reviewed.

What inspection records should I request?

Depending on your purchasing requirements, you may request material documentation, dimensional inspection records, welding inspection reports, and applicable non-destructive testing results. Confirm the required inspection methods and acceptance criteria before production begins.

What can cause a replacement boom to develop cracks prematurely?

Possible contributing factors include impact loading, operation beyond machine limits, unsuitable attachment loads, fatigue, poor pin alignment, welding defects, or inadequate maintenance. If cracks appear, stop using the affected equipment and arrange a qualified inspection before returning it to service.

How can I reduce downtime during a boom replacement?

Confirm the exact machine configuration and mounting dimensions before ordering, prepare suitable lifting equipment and qualified installation personnel, and check the pin joints and hydraulic connections during installation.
