タイトルまたは説明

The loadframe is consisted of four-column, ballscrew, upper crosshead, middle crosshead and worktable, and the adjustable speed system is installed underside of the worktable. High accuracy, wide range and stable Japan Panasonic AC servo motor drive the ballscrew pair rotating through syn-deceleration system, the ballscrew pair drive middle crosshead, make the tension clamp(compression, bending) move up and down, then realize load and offload to the specimen. This structure has enough stiffness to apply high efficiency and stable moving. Key parts are processed on the processing center to ensure the accuracy of the load frame. Ballscrew is E5 class.

Standard grips: wedge tension, compression and bending clamp each one set. 
Electric part:

1. (1)    Adopt stable and reliable Japan Panasonic AC servo driving system and servo motor, with the protection device of overcurrent, overvoltage Speeding and overload. The adjustable rate can up to 1:*****0
2. (2)    With the protection function of overload, overcurrent, overvoltage, displacement upper and lower limitation and emergency stop.
3. (3)    The electric circuit refered to international standard and conform to national testing machine electric standard, high an excellent performance on the anti-jamming test to ensure the stability of controller and accuracy of test data.
