As a nationally recognized "Little Giant" enterprise specializing in niche, specialized, and innovative products, Wantong Hydraulics boasts a dedicated production line for hydraulic cylinders used in trailers, equipped with high-precision machining equipment and an automated assembly line—significantly boosting production efficiency compared to traditional manufacturing methods. The company has established specialized testing standards for trailer cylinders, ensuring each unit undergoes rigorous evaluations, including bump-simulation tests mimicking long-distance road transportation, environmental assessments conducted across a wide temperature range, and lift-cycle durability tests. These measures guarantee the stable performance of its products. Currently, the company’s annual production capacity for trailer hydraulic cylinders fully meets the bulk procurement needs of trailer manufacturers, while also maintaining short delivery lead times.

Recently, Shandong Wantong Hydraulic Co., Ltd. (hereinafter referred to as "Wantong Hydraulic") announced that its hydraulic cylinders—specifically developed for trailers—have entered mass production and delivery. These products cater to the lifting, extending, and supporting needs of various trailer types, including flatbed trailers, container trailers, and specialized trailers. With their standout features of "stable load-bearing capacity and excellent shock resistance," they have become a key, highly compatible component in the trailer transportation industry.

According to the technical team at Wantong Hydraulics, the hydraulic cylinders used in trailers feature cylinder bodies crafted from 42CrMo alloy steel via a cold-drawing process, paired with high-strength piston rods. Operating within a medium-to-high pressure range, these cylinders can handle payloads ranging from small to medium capacities, effectively meeting the lifting and supporting needs of trailers across various tonnages. The sealing system incorporates an advanced combination of imported oil-resistant rubber and PTFE seals, complemented by dust-proof ring designs, which successfully address the issue of leakage caused by bumps during trailer transportation, ensuring exceptionally low failure rates even under continuous operation. To meet the demands of outdoor trailer operations, the cylinder surfaces are treated with cathodic electrophoretic coating, significantly enhancing their corrosion resistance and making them well-suited for challenging environments such as rain, snow, and high temperatures. Additionally, the product line offers customizable options for a wide range of standard cylinder bore sizes and stroke lengths, including specialized types like trailer support leg cylinders, cargo compartment lift cylinders, and telescopic boom cylinders.
