Belt tensioning device for adjustment of pulling force to safety levels, has display which shows tension value and installed in integrated unit connected with tensometer which detects tension of hook using resistor

摘要

The device has a display (103) installed in the integrated unit (102) to show the tension value. Integrated unit is connected with the tensometer (101) which is installed on the connection between fixed hook (11) and the body (10) of the device and detects the tension of the fixed hook. A movable wheel (13) is mounted on the tension rod (12) and the belt (14) is wound on the wheel.
