The invention relates to a board-side net-hauling tension testing device which comprises a machine frame. A power device, a torque meter and a board-side roller are coaxially arranged on the machine frame, one end of the board-side roller is fixedly connected with the torque meter, and the other end of the board-side roller is axially and radially positioned by a telescopic ejection pin. A tested net piece is arranged above the board-side roller in a covering mode, the front end and the rear end of the tested net piece are respectively fixed by one net locking guide roller, band friction pressing devices are arranged on two sides of each net locking guide roller, adjusts net piece rolling friction force by adjusting clamping forces on two sides of the net piece and accordingly simulates net piece load in a static or moving state. Pull press sensors are installed at two ends of each of front and rear net locking guide rollers and used for detecting change of tightness degree of the front-rear net piece when the board-side roller rotates. The other end of each pull press sensor is fixed to a bottom sliding guide rod. A wrap angle of the net piece to the board-side roller can be changed by moving the position of the sliding guide rod on a guide rail.
