Specifications and Testing Procedures
Columns can be designed and tested with dynamic and static loads exceeding current standards if specifically requested by the client. All columns undergo a series of tests to ensure compliance with structural calculations and suitability for overloads as per the EN 1493 (2010) directive. A specially designed machine is used for these tests, featuring a computerized control unit that manages data from a dedicated load cell interfacing with a hydraulic control unit equipped with special proportional valves and a variable capacity pump. The machine can handle capacities over 100 metric tons and is adaptable for testing columns ranging from 4 tons to over 60 tons.
Testing Procedures- Dynamic Overload: Tested at 15% above the nominal capacity for the entire lifting stroke.
- Static Overload: Tested at 50% above the nominal capacity at maximum height for at least one hour.
- Structural Deflections: Survey of column deflections and potential permanent deformations.
- Vibration Survey: Monitoring of vibrations emitted during dynamic tests.
- Electric Current Absorption: Measurement of current (Ampere) during dynamic tests.
- Safety Systems Functionality: Verification of safety systems such as wear nut sensor, obstacle sensor, lifting sensor, safety electronic endstrokes, and installed buttons.
