For the prevention of loss of damage during the loading and unloading of goods from the semi-trailers jack stands are widely used. Jack stands for semi-trailers are the equipment that can be easily installed to a trailer during the need when there is no towing vehicle attached to the trailer. Meeting all the requirement of safety regulations, the jack stands are specifically designed for supporting the trailer parked on an uneven or slippery road. The jack stands for semi-trailers allows the required friction to be given to the trailer when there is a chance of slipping away. The heavy goods loaded or to be loaded onto the trailer creates a risk of hazardous situation at a place where there is no towing machine available to support the trailer. The jack stands are manufactured from heavy metal which provide a longer life cycle to them and are neatly designed for specific trailer need.
