4. Features:
* Front and rear columns are symmetrical. Pendulum arm isdesigned of cantilever beam support, with simple structure and high machined precision
* Apply high precision bearing with small friction. Absorbing energy without loading is less than 0.3%
* High rigid pendulum arm prevents axial and transversevibrations
* Double reduction gear system replaces old style drivesystem with high efficiency and avoiding transmission failure
* Round pendulum head design reduces windage losses to the most.
* Exchangeable pendulum is simple to change to satisfyimpact energy of 150J,300J,450J,600J,750J
* Electromagnetic release ofpendulum hammer and electromagnetic clutch for locking the pendulum and raising it to its initial position. A damper is equipped to prevent strong bump when clutching
* Full-closed enclosure with high safety to prevent brokensample from splitting.Protective screening has interlock door.When the door opens, most operations can't work to avoid any wrong operation
* When connected to aprinter, user input information and test results will be printed. computer with software control is
available to realize semiautomatic operation. Operator only need charge Others can be controlled by software
* Optional specimen feeding system is available. Combinedwith computer and software, fully automatic operation can be realized.
* Optional cooling system is available to satisfy cold specimentest down to -180℃

different collecting box
5.Software Interface:
* Safety pin guaranties the impact action, standard protection shell to avoid any accident.
* Pendulum will automatically rising and ready for next impact action after specimen breakout.
* PC software to display the energy loss, impact tenacity, rising angle, test average value etc. test data and result, also the
curve display available, with calculation and report printing function. The dial scale can show test results too
