Targeting these pain points in daily operation, this session introduces SUNHUNK’s solutions developed from load‑bearing structure and manufacturing process perspectives.
Welding quality is the fundamental safeguard for floor‑plate service life. All weld seams on SUNHUNK floor plates adopt fully‑automatic robotic welding technology. This effectively eliminates uncertainties caused by manual operation and ensures that the connection strength of every unit meets the design criteria.
To withstand impact loads under harsh working conditions, SUNHUNK abandons simple conventional support structures and adopts a high‑strength five‑longitudinal‑beam base frame with a frame height of 150 mm. Compared with beam‑free or weak‑beam structures, this design greatly improves the floor plate’s bending resistance. It delivers superior impact resistance even when large‑sized materials such as ores and rocks fall directly onto the body.
This is one of SUNHUNK’s core technologies that set it apart from competing products. The innovative flared‑end beam structure effectively distributes stress loads from the single tipping‑hinge point to the entire rear section of the floor plate, enabling the whole frame to share the load. Actual tests show that this design increases the load‑bearing area of the frame by 27 % and greatly reduces the risk of weld damage caused by local overload.
The main floor‑plate board is made of dedicated H850 high‑strength steel plate, featuring excellent tensile strength and favorable elongation. In field operation, the H850 material delivers outstanding fatigue resistance under the heavy weight of high‑density ores or impacts from frozen soil and large chunks of material. Its performance advantages become more prominent under complex working conditions and extreme loads.
