Recently, a severe heatstroke incident occurred in Zhanqian District, Chizhou City, when a power company employee was working on a high-voltage telephone pole under extreme temperatures. The temperature had reached 37°C, and the worker, a 40-year-old electrician named Master Zhang, continued his task for three consecutive hours at the top of a 10-meter pole. Suddenly, he collapsed due to heat exhaustion and fell into unconsciousness while working at height. Fortunately, he was wearing a safety harness, which prevented him from falling to the ground. Upon receiving the emergency call, local rescue teams rushed to the scene. They found Master Zhang sitting on the crossbeam of the utility pole, leaning against the pole, unresponsive. A nearby worker was trying to cool him down with a fan. The fire department quickly arrived and climbed up the pole. They secured Master Zhang with a safety rope, attached a rescue harness, and set up a pulley system at the top of the pole. Using the rope, they carefully lowered him to the ground over the course of an hour. After being rescued, Master Zhang was immediately taken to the hospital for treatment. According to reports, the incident happened around 10 a.m., when Master Zhang and his team were working on a maintenance project near the main motor city of Chizhou. The intense midday sun contributed to the sudden onset of heatstroke, causing him to lose consciousness while working at height. His quick response and the use of proper safety equipment likely saved his life. This incident highlights the dangers of working in extreme heat conditions and underscores the importance of proper safety measures, hydration, and rest for workers exposed to high temperatures. It also serves as a reminder of the risks faced by utility workers who often perform critical tasks in challenging environments. (China Labor Insurance Network) Double-Column Universal Material Tensile Test Machine A Universal Tensile Testing Machine, also known as a universal testing machine (UTM) or a materials testing machine, is a versatile instrument used to determine the mechanical properties of materials. It is commonly used in industries such as manufacturing, construction, and research laboratories.

The machine applies tension, compression, bending, and shear forces to test the strength, elasticity, and durability of various materials such as metals, plastics, textiles, rubber, ceramics, and composites. It can measure parameters such as tensile strength, yield strength, elongation, modulus of elasticity, and fracture toughness.
A typical UTM consists of a load frame, grips or fixtures to hold the specimen, a load cell or force transducer to measure the applied force, and a displacement transducer to measure the deformation or displacement of the specimen. The machine is controlled by a computer or a control unit that allows the user to set the testing parameters and record the test data.
During a tensile test, the specimen is placed between the grips and a controlled force is applied until the specimen fractures. The machine continuously measures the applied force and the corresponding deformation or displacement of the specimen. The data is then plotted on a stress-strain curve, which provides valuable information about the material's behavior under tension.
Universal Tensile Testing Machines are crucial in quality control and material selection processes. They help manufacturers ensure that their products meet industry standards and customer requirements. They also aid researchers in developing new materials and improving existing ones.
