1. Pay attention to the protection of exposed parts. Electrical components and connectors must be arranged on the inside, or add a protective cover. Because the entire vehicle is exposed to corrosion and easy to enter water, dust covers are added to these parts. For example, the exposed section of the piston rod of the tilt hydraulic cylinder and the steering hydraulic cylinder need to be equipped with a dust cover; the exposed process holes or functional holes on the body also need to be equipped with waterproof plugs.
2. The overall structure of the hydraulic pallet truck considers anti-corrosion media accumulation. Try to avoid the closed area, or keep the closed system ventilation performance and drainage system good, battery electric forklifts such as reach forklifts, ventilation windows can be opened to maintain the heat and ventilation of the motor, and the bottom of the battery box can also be opened with leakage holes or installation products. Liquid container.
3. Pay attention to avoid the corrosion of the crevice of the stacker, stress corrosion cracking, and electrochemical corrosion. Seal the inevitable gap structure such as the tailor-welded gap of the engine cover with sealant. Dissimilar metal connections should be as close as possible to the metal potential, or use insulation measures to avoid electrochemical corrosion.
4. The structure of the parts should facilitate the implementation of the protection process, and process holes should be opened when necessary. For example, the opening position on the fuel tank should be conducive to covering the nozzle of the spray gun, and the surface should be shot peened. For chemical pre-treatment workpieces such as overhead guards, process holes should be opened to prevent liquid accumulation.
5. Pay attention to protection in appearance design to avoid accumulation of water vapor and dust. The design concept of electric forklift can be used for reference, so that the shape of the electric forklift is smooth, the beauty of the whole vehicle is improved, and the functional design is not easy to accumulate water and dirt.
