Safe Operation Rules
Only the workers who are familiar with safe operation rules and maintain demand of this tension machine and are professionally trained could be allowed to operate.
(1)When operating tensioner, you shall control handle and adjust pressure steadily and avoid over-violent and quick force and brutal operation. When tension laying , special attention shall be paid to prevent reducing or increasing tension to a large extent to result in conductor fluctuating greatly and damaging span frame and other buildings.
(2) When tensioner works, it is prohibited that operators give up operating or leave puller.
(3) Both operators of tensioner and puller shall communicate each other to avoid that puller begins to work under operating condition of tensioner not tension laying and cause serious accident.
(4) In the process of tension laying , continuously observe each pointer; water temperature of engine shall be not more than 95℃; hydraulic oil temperature shall be not more than 85℃; Oil-filling pressure shall be not less than 1Mpa and not more than 1.8Mpa; brake oil pressure shall be not less than 1.8Mpa and not more than 4Mpa. Otherwise, the machine shall be stopped immediately for check.
(5) Absolutely prohibit using reverse pulling function to brake.
(6)In the process of tension laying, it is strictly prohibited that brake handle is put in brake position; otherwise, serious accident will be caused.
(7) Pressure of each safety valve shall be preset, avoid random adjustment! If accidents, for example, tensioner fails to work, are caused from adjusting valve without permission, it will bring you much trouble and loss.
(8) Regularly check the fixed bolt of the nylon sector, prevent loose bolt to damage the wires and cause unnecessary losses.
(9)When tension stringing, the pull handle should be middle position. It is forbidden to throw the handle to prevent to cause serious accident as running line.
(10) When tensioner operates, rotary speed of engine keeps around 1200r/min to maintain higher power and prevent overheating of hydraulic oil.
(11)Under operating condition of driving, to change driving direction of tensioner shall be carried out after tension pulleys stop completely.
