Static load testing jack
Static load testing hydraulic jack
Load test jack can be used for jacking, pulling, pressing, squeezing, pushing, etc. It is widely used in many working scenarios and industries such as foundation inspection, transportation, railway, bridge, subway, construction, factories and mines.
How to do static load test ?
Loading capacity is usually applied in two ways; with a jack which reacts against a kentledge heavier than the required test load or using a jack that reacts against beams held down by tension piles acting as anchors.
Generally, horizontal jacks are used to load piles when testing piles. The loading capacity is not less than 1.2 times the maximum test load. The load value applied is measured by a force ring or load cell. For the reciprocating cycle test, a two-way reciprocating hydraulic jack can be used. The horizontal force action line should pass through the ground elevation (the ground elevation should be the same as the actual project pile cap ground elevation).
When the concrete on the contact surface between the jack and the test pile is not dense or flat, it should be reinforced or flattened. In order to prevent local squeezing damage at the load application point of the pile body, steel blocks can generally be used for local load application points. Strengthen or reinforce the contact between the jack and the test pile.
