AAK Hydraulic Cartridge Counterbalance Valve ensures that the crane is accident free, and Sulaiman i

Sulaiman comes from Brazil, and their hydraulic cylinder business is mainly with local engineering machinery manufacturers. In the second half of last year, a batch of their hydraulic cylinders used on cranes almost caused an accident. The root cause was hydraulic cartridge counterbalance valve, which was lack of function. During construction of the crane, the hydraulic oil pipe burst suddenly, and the crane dropped rapidly to the ground. During on-site inspection, it was found that the oil cylinder operated normally, and the hydraulic system also complied with the principle. The local manufacturer of the hydraulic cartridge counterbalance valves reported that there was no problem with manufacturing quality.

Although this batch of hydraulic counterbalance valves was not purchased by Sulaiman, he always felt that the reason for abnormality of equipment was hydraulic cartridge counterbalance valve.
