Light Pole Straightening Machine


In general, we produce light pole by hot roll steel coil. while, the plate quality can be various. when the poles are after light pole welding machine or hot drop galvanization. for sure, the poles will curved into banana shape because of internal stress. to get better product or processing, we shall use straightening machine to calibration the straightness.

the Light pole straightening machine is a simple hydraulic press, with longer working table. Obviously it is suitable for pole production. Both side support points over the working table is adjustable. First, operator can put the light pole over the table.  then stamp on foot switch to control the hydraulic press cylinder up and down to press the pole. it will make pole straight. the pressing force can be 63T or 80T according to pole size. while the machine is just suitable for light pole. for bigger pole like high mast or electric transmission tower, the pole diameter will be too big and need higher force.

And for high mast pole, normally we need to do two or more seam welding to balance the internal welding stress. the straightening machine structure will be different.
