Tashi Delek! Operating trucks on the Tibetan Plateau, why do some vehicles retain high value for five or six years, while yours suffer from floor leakage, bulging cargo bodies and jamming hydraulic cylinders in just two to three years? It is not bad luck, but the fundamental build quality that makes all the difference.
Here are three key tips to help you pick high-resale-value trucks.

Rugged washboard roads and frequent haulage of muck and gravel wear down ordinary steel plates, which tend to thin out and develop leaks within two to three years.
SUNHUNK adopts K450TUF wear-resistant steel jointly developed with steel mills, with a measured Brinell hardness exceeding 412. By comparison, conventional wear-resistant steel on the market only ranges from 186 to 324 in Brinell hardness. Superior wear resistance prevents floor penetration and maintains higher residual value.

Many dump trucks develop bulging sides and sagging floors over time due to flawed structural design.
SUNHUNK equips the cargo body with 270mm full-length cross beams to firmly support side panels and avoid bulging. Instead of basic twin L-shaped longitudinal beams commonly seen elsewhere, we apply a four-longitudinal-beam floor frame (120mm height) plus flared beam structure. The load is distributed evenly across the whole frame to keep the body free from deformation, ensuring excellent resale value.

As a core component, faulty cylinders cause work delays and potential safety hazards. The SUNHUNK X-Power Hydraulic System delivers outstanding performance in four aspects: lightweight design, fast operation, high strength and superior safety.
Made of high-strength steel and one-piece seamless tube with no welds — lighter yet tougher.
Optimized roller polishing process raises surface smoothness and hardness by 45%, enabling faster lifting and retraction.
Internal clearance controlled within 0.07mm for strong resistance against lateral loads, free from bending and deflection.

High-pressure hoses feature a rated working pressure of 28 MPa and a burst pressure of 112 MPa, four times the standard working pressure for reliable high-pressure operation.
This low-failure hydraulic system extends service life and further boosts vehicle residual value.
Tough floor, rigid cargo body and stable cylinders — retain great value after years of service. This is the reliable "Iron Yak" for truckers on the plateau.
