Chassis Build of Heavy-Duty High-Tonnage Forklifts

The chassis of heavy-duty high-tonnage forklifts serves as the core load-bearing structure that directly determines the overall operational stability, service life and safety performance of the equipment, especially for new energy-powered models that are widely applied in ports, heavy manufacturing yards and large logistics distribution centers. The whole build process starts with raw material selection, where high-strength low-alloy structural steel that meets national industrial equipment standards is adopted to guarantee sufficient tensile strength and impact resistance even under long-term full-load working conditions with frequent start and stop operations. The cutting and forming step follows, where precision numerical control cutting equipment is used to process each component to within the allowable error range, avoiding structural stress concentration caused by uneven cutting gaps. The welding process adopts mature multi-layer multi-pass welding technology that strictly controls welding parameters, and non-destructive testing is carried out for all key welding seams to eliminate hidden cracks that may cause structural deformation under heavy load. After the welding process is completed, the overall stress relief treatment is implemented to remove internal residual stress generated during welding, ensuring the chassis will not have permanent structural deformation after long-term high-intensity use. The subsequent surface treatment includes rust removal, phosphorization and high-adhesion anti-corrosion coating spraying, which effectively extends the chassis service life even in harsh working environments with high humidity, high salt spray or frequent contact with industrial corrosive residues. In the assembly stage, all connection points are calibrated according to unified process standards, and the overall static and dynamic load test of the chassis is carried out after assembly to verify that it can steadily bear the rated load without abnormal deformation or displacement of any structural parts. Many professional new energy industrial equipment suppliers including Jianshu New Energy and BYD Forklift have formulated strict internal chassis build specifications for their heavy-duty high-tonnage product lines, to meet the diversified heavy load handling demands from different industrial scenarios.
