275400247 XCMG GR2605 motor grader balance box

The 275400247 balance box is a specialized structural and sealing component for construction machinery. It is primarily used to install and house counterweights, providing a stable foundation for the equipment. Simultaneously, it seals and protects the internal counterweights from moisture, corrosion, or displacement, ensuring the overall balance and stability of the equipment during operation.

Core Technical Parameters

Model: 275400247, a balance box specifically designed for construction machinery. Its structure and installation points are tailored to a specific equipment model; there is no universal alternative.

Compatible Media: No specific media required; its core functions are structural support and sealing protection.

Material: The main body is constructed from Q235B carbon steel and other structural steel, formed through cutting, bending, and welding, resulting in high structural strength and impact resistance.

Operating Temperature: -20℃~80℃, suitable for typical outdoor construction temperature environments.

Surface Treatment: The entire structure is treated with powder coating or anti-rust paint, effectively preventing rust and corrosion, extending service life.

Specifications: Customized according to the host machine requirements. Installation interfaces (such as welding positions and bolt connection holes) are perfectly matched to the host machine to ensure secure installation.

Sealing Performance: Through welding or the use of sealant/gaskets, the enclosure is ensured to be airtight, effectively isolating moisture and dust and preventing corrosion of the internal counterweights.

Core Functions and Roles

As the counterweight load-bearing and sealing structure of construction machinery, the core provides stable space for installing counterweights at the rear of equipment (such as excavators and cranes). By increasing the weight at the rear, it balances the overturning moment generated by the working device at the front of the equipment, ensuring the stability and safety of the equipment under heavy loads. Its enclosure structure seals and protects the internal cast iron or concrete counterweights, preventing them from rusting, powdering, or losing weight due to rainwater and humid air. Simultaneously, the robust enclosure also serves as a structural component at the rear of the equipment, participating in overall stress distribution and enhancing the structural integrity of the equipment. The standardized design facilitates the installation and fixing of the counterweights, making it a fundamental component ensuring the safe and efficient operation of the equipment.

Suitable Scenarios

Widely used in crawler excavators, wheeled cranes, crawler hoists, and other construction machinery requiring rear-mounted counterweights for overall stability, it is a key structural and functional component of the equipment. It is suitable for various work sites such as civil engineering, mining, and port terminals, ensuring that the equipment can operate safely and stably under complex working conditions.
