Abstract
Sleepers, also known as ties, are a type of railway accessory. However, the materials used are no longer limited to wood, so the term "sleeper" is more scientifically accurate. Although sleepers may appear monotonous and unremarkable, their role is significant. Sleepers support the rails, maintain their position, and transfer the immense pressure from the rails to the ballast. They must possess a certain degree of flexibility and elasticity; neither too hard nor too soft. When a train passes, they can deform slightly to cushion the pressure, but they must return to their original state as much as possible after the train has passed. The sleeper full-performance testing system developed by Riyue Technology employs new technologies such as high-precision load sensors, microcomputer control, and electro-hydraulic proportional hydraulic loading systems. It can accurately and quickly detect the static load strength of various sleepers and test their actual load-bearing capacity. Static load points can be arbitrarily set, and data result reports are automatically printed. The sleeper static load testing machine mainly consists of a press, trolley, track, lifting mechanism, hydraulic system, and electrical control system.
