Specialized Testing Machine Series
LBT-CS20 Safety Belt Fall‑Arrest Self‑Regulating Device Impact Performance Tester
The LBT‑CS20 Self‑Regulating Fall Limiter Impact Performance Tester is a specialized mechanical testing instrument developed specifically for fall‑protection safety equipment. It was designed in accordance with GB/T 6096‑2020, “Fall Protection—Methods for Testing the Performance of Safety Harness Systems,” and is primarily used for preventive mechanical performance testing of power‑industry safety tools such as self‑regulating fall limiters, self‑locking devices, and energy absorbers. The device features a dual‑control system, allowing seamless switching between two control modes, and offers simple, convenient operation. It is widely employed in safety‑tool testing laboratories of power utilities, third‑party quality‑inspection agencies, manufacturers of personal protective equipment, and research‑and‑testing institutions, enabling comprehensive assessments of impact performance and mechanical load capacity for high‑altitude fall‑protection devices—including self‑regulating fall limiters, self‑locking devices, and energy absorbers. It can be utilized for type tests during new‑product development, factory acceptance inspections, and periodic preventive testing of power‑industry safety equipment.
This microcomputer‑controlled lever‑type four‑ball friction and wear testing machine is a high‑precision, lever‑and‑weight‑based four‑ball tester that strictly complies with multiple national, ASTM, and DIN standards for lubricant evaluation. It employs a point‑contact sliding friction mode to assess critical performance parameters of lubricating oils and greases, including extreme pressure resistance, wear resistance, coefficient of friction, and shear stability. The instrument can determine the PB maximum no‑seizure load, the PD scuffing load, and the ZMZ comprehensive wear index, making it widely used in petrochemical enterprises, third‑party testing laboratories, university tribology research labs, and new‑material R&D institutions for product quality inspection, formulation development, and scientific research experiments.
The LBT‑YJ300 microcomputer‑controlled static stiffness testing machine for elastic pads is a specialized instrument developed by our company, designed for use in research institutes, industrial and mining enterprises, and other facilities. This testing machine can also be employed to evaluate the static stiffness characteristics of rubber joints in locomotive traction rods, motor suspension rods, axle box pull rods, connecting rod assemblies, and similar components. It boasts a compact design, low noise levels, and high measurement accuracy. Featuring an all‑mechanical structure, it utilizes an AC servo motor coupled with a reducer and incorporates a fully sealed configuration, eliminating the need for lubricant replacement during operation and preventing hydraulic oil leakage or proportional valve blockage. As such, it represents a new generation of environmentally friendly testing equipment.
WDW-20Z Microcomputer-Controlled Carton Compression Testing Machine
The carton compression testing machine is a specialized testing device for the packaging industry, featuring microcomputer control and high‑precision force measurement. It is an dedicated instrument for evaluating the compressive strength of cardboard boxes and various types of packaging containers. Primarily used to assess the load‑bearing capacity of cartons, it can perform compression strength tests and simulated stacking‑pressure tests. The test data serve as an important reference for designing appropriate stacking heights for finished product packaging and are widely employed by packaging manufacturers, food and pharmaceutical companies, home appliance and light‑industry enterprises, third‑party inspection agencies, and research laboratories. The equipment is suitable for assessing the mechanical properties of corrugated boxes, honeycomb containers, and other packaging materials. Equipped with a microcomputer‑based closed‑loop control system, it supports multiple test modes, including constant force, constant deformation, and constant displacement. Loading is smooth, force acquisition is sensitive and reliable, and the system operates without gear changes, ensuring accurate testing across all force ranges. It can simulate real‑world warehousing and stacking conditions to conduct sustained‑pressure tests, recording force, displacement, and deformation data in real time and automatically generating test reports, thereby providing robust data support for packaging design and factory‑level quality inspection. The machine also features multi‑level protection against overload and overtravel, ensuring safe and stable operation.
WDW-50A Microcomputer-Controlled Mannequin Tensile Testing Machine for Seat Belt Safety Straps
The microcomputer-controlled seat belt tensile testing machine is primarily used for static load testing of seat belt webbing and lanyards, as well as for static load testing of components. It also performs deformation tests on energy absorbers and tests the force required to trigger accidental release. In addition, it can conduct mechanical property testing and analytical studies on a wide range of metallic, non-metallic, and composite materials. This equipment is extensively employed in industries such as aerospace, petrochemicals, mechanical engineering, vehicle manufacturing, wire and cable production, textile fibers, plastics and rubber, ceramic and building materials, food and pharmaceutical packaging, metal materials, and construction engineering, as well as in universities, research institutes, technical supervision agencies, and quality inspection stations. It supports tensile, compressive, bending, peel, shear, tear, puncture, and burst tests, along with various high- and low‑temperature tests, in accordance with standards including GB, ISO, ASTM, JIS, and DIN. The machine can determine material parameters such as yield strength, tensile (compressive, flexural) strength, elongation at break, proof stress, non‑proportional stress, and elastic modulus.
