Selection And Purchasing Skills Of Forklift Parts
Dec 14, 2018

1. See if the parts number and specifications of forklift truck fittings are suitable. Most parts of forklift truck fittings have a specific part number and technical parameters. When purchasing electrical system accessories, attention should be paid to checking whether the voltage and power of the replacement parts are the same; when purchasing the driving belt of forklift engine, attention should be paid to the type and length width.

2. See if the logo of the outer packing is complete and the quality of the outer packing of forklift truck accessories is relatively good, and the handwriting on the box is clear and the overprint color is bright. Some important components such as generator, starter, hydraulic pump, etc. are also equipped with operation instructions, certificates and inspector's stamps to guide users to use maintenance methods correctly. Therefore, when choosing and purchasing forklift truck parts, it should be carefully recognized in order to prevent the purchase of counterfeit and inferior parts.

3. See if the shape and size of forklift truck parts are deformed. Some parts of forklift truck are easily deformed due to improper manufacturer, logistics transportation and storage. When inspecting, the axle parts can be rolled around the glass plate to see if there is light leakage at the joint between the parts and the glass plate to judge whether they are bent or not; when choosing steel sheets or friction sheets of forklift clutch driven disc, the steel sheets and friction sheets can be selected in front of the eyes to observe whether they are warped; when choosing sealing parts such as forklift oil seals, the oil seal end surface with skeleton should be round, and can be pasted with flat glass. The outer edge of the oil seal without skeleton should be straightened out and deformed by hand grip, so that it can be restored to its original state after loosening hands. When choosing and purchasing all kinds of liners, we should also pay attention to the use of professional measuring tools to check the geometric size and shape of accessories.

4. See if the joint part of forklift truck fittings is smooth during handling and storage, or because of vibration and turbulence, burrs, indentations, damages or cracks often occur in the joint part, which will affect the installation and use of forklift truck fittings. This point should be checked carefully when choosing and purchasing or when inspecting goods.

5. See if the surface of forklift truck fittings is corroded and qualified. It has certain accuracy and bright finish. The more important the fittings are, the higher the accuracy is, and the more strict the packaging is, the more rust-proof and anti-corrosion. When purchasing or inspecting goods, attention should be paid to inspection. If rust spots, mildew spots, cracks in rubber parts, loss of elasticity, or obvious lathe knife lines on the journal surface are found, replacement treatment should be given.

6. See if the protective surface of forklift truck fittings is intact. Most of the fittings are coated with protective coating when they leave the factory. For example, piston pins and bearing bushes are usually protected by paraffin while piston rings and cylinder liners of forklift trucks are coated with rust-proof oil and wrapped in wrapping paper. The valve and piston of forklift engine fittings are encapsulated in sealed plastic bags after being immersed in rust-proof oil. If it is found that the seal sleeve of the sealing bag is damaged, the packing paper is lost, and the rust-proof oil or paraffin is lost, it should be returned or exchanged.

7. See if the glued fittings are loosened or not. Check forklift fittings which are composed of two or more parts. The fittings are processed by pressing, glued or welding. No loosening is allowed between the fittings, such as forklift pump plunger and adjusting arm, forklift clutch pressure plate and clutch plate are riveted together, forklift friction plate and steel are riveted together. The sheet is riveted or bonded; the filter core skeleton of various filter elements is bonded with the filter paper; the circuit and wire head of electrical equipment are welded. If looseness is found in the purchase, it should be replaced.

8. Whether the rotating parts are flexible or not, when choosing and purchasing the turning parts such as oil pump of forklift truck, it should be flexible and non-sticking to turn the pump shaft by hand; when choosing needle roller bearings, one hand supports the inner ring of the bearing, the other hand rotates the outer ring, and the outer ring should rotate freely and quickly, and then stop turning gradually. If the rotating parts fail to turn properly, it indicates that the internal rust or the shape has been deformed, which will affect the use, it should be returned or exchanged.

9. See if there are any spare parts in the assembly, such as the clutch or transmission assembly of the forklift transmission system. The spare parts in the assembly must be complete and intact so as to ensure that the assembly can be assembled and operated smoothly. If the individual small parts on some assembly parts are missing, the assembly parts will not work or even be scrapped.

10. See if the assembly marks of forklift truck fittings are clear. In order to ensure that the assembly relations of other fittings meet the technical requirements, assembly marks are engraved on the surface of some parts (such as timing gears). If there is no mark or the mark is blurred and can not be identified, it will bring great difficulties to assembly work, or even direct misassembly.

11. See if there is wear on the matching surface. If there are wear marks on the matching surface of the fittings, or if the old paint is found after the fittings with paint are removed, it is mostly disguised as the used car dismantling parts. At this time, it can be directly requested to replace them.

12. See whether the surface hardness of forklift truck fittings meets the standard or not. After confirming the purchase and negotiation with the merchants, the broken stubble of the steel saw blade can be used for trial scratch. If there is no scratch in scratch, the hardness is high; if there is a slight scratch after scratch, the hardness is high; if there are obvious marks after scratch, the hardness is low, but it should be noted that the fittings should not be damaged during the test scratch.
