The Railway Inspection Hammer is a professional detection tool independently developed by Yuerui International, specifically designed for the daily inspection and fault diagnosis of railway components such as rails, fasteners, sleepers, and connecting parts. Integrating precise acoustic feedback design, wear-resistant material selection and ergonomic grip, this product helps inspectors quickly identify hidden faults such as looseness, cracks, and internal defects of components by judging the sound difference generated by knocking. It is widely applicable to high-speed railways, conventional railways, urban rail transit and other scenarios, and is an indispensable portable tool for railway operation and maintenance teams. With its lightweight design and reliable performance, it effectively improves the efficiency and accuracy of inspection work, providing a strong guarantee for the safe operation of railway systems.

(1) Precise Acoustic Feedback & Fault Identification
The hammer head is precision machined and heat-treated to ensure uniform material density, which can generate clear and distinguishable sounds when knocking different states of components. For intact components, it emits a crisp and full sound; for loose or cracked components, it produces a dull and hollow sound, helping inspectors quickly locate faults. The double-headed design (round head + flat head) is suitable for knocking different parts: the round head is used for rails and sleepers, and the flat head is for small fasteners and connecting bolts, improving the versatility of inspection.
(2) High Wear Resistance & Long Service Life
The hammer head is made of high-carbon 45# steel, which undergoes quenching and tempering heat treatment, with high hardness and excellent wear resistance. It can withstand long-term high-frequency knocking without deformation or chipping. The chrome-plated surface of the hammer head effectively resists rust and corrosion from outdoor moisture, dust and rail-side chemical substances. The FRP handle has high tensile strength and impact resistance, which is not easy to break or deform, and its service life is 3 times that of ordinary wooden handle hammers.
(3) Ergonomic Design & Portable Operation
The handle adopts an ergonomic curved design, which fits the contour of the human hand, reducing the pressure on the palm during long-term holding. The anti-slip frosted surface of the FRP handle enhances the grip force, avoiding slipping even in oily or wet environments. The lightweight design (minimum 280g) makes it easy to carry in the operation bag, and the long-handle model can reach remote inspection positions without additional tools, improving the flexibility of operation.
(4) Multi-Functional Integration & High Practicality
The hammer tail is equipped with a built-in magnetic nail puller, which can easily absorb and pull out small iron parts such as loose nails, eliminating the need for additional tools. The scale ruler on the handle can be used for simple measurement of component gaps and defect sizes, providing convenience for on-site inspection records. The product is small in size and easy to store, which is suitable for daily patrol inspection and emergency maintenance work of railway inspectors.
