Equipment structure

1. The control panel is located in the front of the machine to facilitate observation and operation, and the power supply is located at the back of the machine.
2. The driving structure is concealed, with a neat and beautiful overall appearance and easy cleaning.
3. The pulley device is located above the machine. The pulley is a nut locking structure, which is convenient for users to replace the pulley and test different samples.
4. Four universal casters with lock are installed at the bottom of the chassis to facilitate movement. During the test, pressing the caster lock can fix the machine without moving.

Components, materials and functions:
