CAT 320 用標準掘削機ブーム

At XINGCHUANG, we supply excavator structural parts for construction contractors, equipment rental companies, and machinery distributors. Our Standard Excavator Boom for CAT 320 is designed for the stated CAT 320 application, with attention to fitment, fabrication quality, and corrosion protection. We hold CE certification and can discuss technical requirements before confirming the replacement specification.

Confirm the Correct CAT 320 Version

Excavator models may have different configurations depending on production year, machine series, and previous repairs. Before ordering a replacement boom, we recommend confirming the machine identification details instead of relying on the model name alone.

Check Pin and Mounting Dimensions

The boom foot, arm cylinder connection, boom cylinder mounting points, and pin diameters must match the intended machine configuration. Mounting width, hole spacing, and clearance around connecting components should also be checked. Incorrect dimensions can cause installation delays or put additional stress on connected parts.

Compare the Existing Boom

Photos of the original boom, its identification plate, and the main connection points can help us review the replacement requirements. If the machine has been repaired or modified, please provide the updated dimensions and any available drawings. We confirm compatibility against the specific configuration before recommending a replacement.

Maintain the Intended Working Geometry

The boom affects the excavator's working range and transfers loads between the upper structure, hydraulic cylinders, and arm assembly. Its geometry must therefore remain consistent with the machine design.

Preserve Cylinder Connection Positions

Incorrect cylinder mounting positions can affect linkage movement and operating geometry. We recommend checking the cylinder pin locations and mounting brackets against the approved dimensions before installation.

Check Clearance and Alignment

The replacement should provide the required clearance for the arm, cylinders, hydraulic hoses, and connecting pins throughout the working stroke. During installation, qualified personnel should confirm that the joints move correctly and that no components interfere with one another.

Review Hydraulic Line Routing

Hydraulic pipe and hose arrangements should be checked against the existing machine. If the boom configuration differs from the original, hose length, clamp positions, and routing clearance may need additional review. Any changes should be assessed by qualified technicians before the machine returns to service.

Fabrication Quality and Surface Protection

Excavator booms are exposed to repeated bending loads, vibration, impact, moisture, and abrasive dust. Suitable steel, consistent welding, accurate fabrication, and protective coating all contribute to structural reliability over time.

High-Strength Structural Steel

The supplied product information specifies high-strength low-alloy structural steel. Material grade and thickness should be confirmed in the technical specification for the selected boom. Where required, buyers can request supporting material documentation to help verify that the delivered component matches the agreed requirements.

Reinforcement at Load-Bearing Areas

Pin joints, cylinder mounts, and welded connections are important areas to inspect because loads are concentrated around these locations. Our production approach focuses on controlled fabrication and suitable reinforcement in accordance with the approved design. Structural changes should not be made without checking their effects on the machine's original geometry and load requirements.

Welding and Stress Relief

The supplied manufacturing process includes full welding and stress-relief treatment. Appropriate welding procedures and inspection help reduce the risk of fabrication defects. Buyers with specific quality requirements should confirm the inspection method, acceptance criteria, and available records before production begins.

Anti-Corrosion Coating

The boom uses surface preparation and anti-rust coating according to the supplied product information. This helps protect exposed steel against normal outdoor exposure, but coating performance depends on preparation quality, environmental conditions, and maintenance. Inspect damaged paint and exposed metal regularly, particularly when equipment operates in wet or muddy locations.

Suitable for Daily Construction Work

Municipal Road Projects

Road renovation and urban construction often involve repeated excavation, trenching, and soil handling. Correct boom geometry and secure pin connections help maintain the intended movement of the working equipment during routine operations.

Foundation and Building Work

Foundation excavation requires the machine to work within a defined reach and clearance area. Before replacing a boom, contractors should confirm that the selected configuration matches the machine and the intended digging requirements.

Earthmoving and Rental Fleets

Equipment rental companies need replacement parts that can be identified and fitted correctly to reduce avoidable downtime. Providing machine identification details and confirming the specification before purchase can simplify procurement for both single-unit replacements and batch orders.

Customer Experience in Malaysia

Supply for Municipal Road Renovation

According to the project information provided to us, a Malaysian engineering company purchased 12 sets of Standard Excavator Boom for CAT 320 in 2025 for municipal road renovation and urban earthwork projects.

Feedback from Continuous Operation

The customer reported that after eight months of operation, the supplied booms showed no reported welding cracks, structural deformation, or serious rust and abrasion issues. The equipment continued to support routine excavation and lifting work during the reported period.

The customer also compared the replacement parts with previously used lower-cost booms that reportedly required replacement every three to four months. These results reflect the supplied customer feedback and should not be treated as a guaranteed service life for every machine or working environment. Actual performance depends on installation, workload, maintenance, and operating practices.

Technical Specifications

The following details are based on the supplied product information. Please confirm the exact machine version, dimensions, and production requirements before placing an order.

Quality Checks Before Shipment

For structural replacement parts, inspection should cover both manufacturing quality and fitment dimensions. We recommend confirming the inspection requirements before production so that the necessary checks and documentation can be arranged.

• Dimensional verification: Check key mounting points and dimensions against the approved drawing.
• Weld inspection: Inspect critical weld areas using the agreed inspection methods and acceptance criteria.
• Surface inspection: Check coating coverage and visible defects before packaging.
• Order verification: Confirm the machine application, part configuration, and agreed accessories.

As a manufacturer, XINGCHUANG works with customers to clarify technical details before production and delivery. We can discuss inspection records and packaging requirements according to the order specification. Any requested test or certificate should be confirmed in advance.

Ordering and Replacement Support

To help us assess your requirements, please provide the CAT 320 machine version, serial number, original part number if available, photographs of the existing boom, and measurements of the main mounting points. For bulk orders, please also indicate the quantity, destination, and expected delivery schedule.

We support technical communication, customized production discussions, and overseas shipment coordination. Delivery time depends on stock availability, drawing approval, production requirements, and inspection arrangements, so we confirm the schedule after reviewing the order details.

Frequently Asked Questions

Can I order by the excavator model name alone?

We recommend providing more information than the model name. The machine serial number, production version, original part number, and photographs of the connection points help us verify the required configuration and reduce the risk of a mismatch.

What should I do if the old boom has visible cracks?

Stop using the affected equipment and arrange an inspection by qualified personnel. The cause of cracking should be assessed before fitting a replacement, as related pins, bushings, cylinder mounts, and connected structures may also need inspection.

Does the Standard Excavator Boom for CAT 320 come with pins, bushings, and hydraulic pipes?

The supplied product information does not specify the standard accessory package. Please confirm whether pins, bushings, pipework, clamps, and other connecting components are included in your quotation so the order matches your installation requirements.

What documents can be supplied with the order?

Available documentation depends on the agreed order requirements. You can ask us to confirm the applicable product specification, inspection records, packing list, and relevant certification documents before placing the order.

How should the boom be stored before installation?

Store the component on a stable support in a dry, well-ventilated area. Protect machined mounting surfaces from impact and corrosion, avoid placing loads on unsupported sections, and inspect the coating before installation. Follow the handling instructions supplied for the component.
