Vertical Tensile Force Testing Platform

The vertical tensile force testing platform provides a precision measurement and certification facility for hydraulic bolt tensioners, hydraulic nuts, and hydraulic cylinders used in high-strength bolt pre-loading applications. Configured for vertical orientation to match the typical installation axis of tensioning equipment, the platform allows the actual pre-load output of tensioners to be measured and verified under controlled conditions, with results directly applicable to field calibration and equipment acceptance testing requirements.

A precision tension load cell provides traceable force measurement across the rated capacity range of the tensioner under test. Real-time digital force display and data recording support calibration certificate generation, pre-delivery acceptance testing, and periodic re-calibration programs. Measurement traceability to national standards is maintained through the calibration chain of the reference load cell, supporting compliance with quality management standards and safety case requirements for tensioner equipment used in critical bolt joints in wind power, oil and gas, and power generation applications.

The platform accommodates different tensioner body diameters and connection thread configurations through interchangeable fixture sets, providing testing coverage for the full range of tensioner sizes in regular production or service. Load cell range modules can be exchanged to match the capacity of the tensioner under test, maximizing measurement accuracy across the full testing range. Integration with PC-based data acquisition and reporting software supports automated test cycle management and certificate generation. Suitable for tensioner manufacturers, calibration service providers, and major industrial operators maintaining in-house tensioner calibration programs.
