Application:
MGW-6500 micro-computer electro-hydraulic servo static load anchorage testing machine is used for anchorage fixture connector static load anchoring performance test, prestressed steel strand anchorage, clamp and connector for concrete structure and component, prestressed steel strand anchorage, clamp and connector, cable anchorage, fixture and connector, carbon fiber prestressed reinforcement, prestressed tendon anchorage, fixture and connector Test and Research on load anchorage performance. It can realize the closed-loop control such as constant rate loading and constant rate deformation, and can automatically calculate the technical indexes of anchorage connector efficiency coefficient η a, fixture efficiency coefficient η g, and the total strain ε APU specimen technical index of the assembly part's stress length when the measured ultimate tension is reached.
Applied Standards:
GB/T14370-2007 《Anchors, fixtures and connectors for prestressed tendons》steel strand-anchor anchorage performance test under static load
JTT 329-2010 《Anchors, fixtures and Connectors》 for prestressed Steel strand for Highway Bridges" to judge whether the mechanical properties of steel strand anchors meet the specified requirements.

Features
Bearing framework
Including plate, left bearing beam, horizontal bar, septum beam, push-pull safety net, right bearing beam, column load sensor; The horizontal bar runs through the whole frame, and is connected to the left bearing beam, the septum beam and the right bearing beam, which is fastened by the nut to form the four-bar load frame; The frame is covered by a push-pull safety net to facilitate loading and unloading of samples. The backing plate is connected with the left bearing beam to fix the anchor ring, and the column sensor is connected with the right bearing beam to connect the piercing jack. The load-bearing frame structure is safe and reliable and convenient for personnel operation.
Displacement sensor device
The device is installed on the core jack to detect the displacement of the piston of the main cylinder. Photoelectric encoder is fixed on the cylinder cylindrical bearing part, the anchor bolt end fixed on the plate bending, between two guide bar and plate is equipped with linear bearing, the piston rod out, move through the screw drive the bending plate of bending plate, realize the encoder process, the plate above two root spring, when the piston back up the reset function. The linear bearing improves the ability of horizontal piston to bear lateral force.
Body of piercing jack
The core jack is placed on the car body that can be reciprocated sliding on the guide rail for easy adjustment of the installation height of the jack.
