The invention discloses a construction technology for loading and unloading long materials by using a simple and eccentric jack. The technology is mainly characterized in that four carrying arms (2) which can extend and be folded are manufactured, and are correspondingly installed above a vehicle chassis crossbeam and below a carriage. When a long material is loaded and unloaded, the four carrying arms (2) extend and prop against the bottoms of two crossarm angle bars (3), and four pillars (4) are adjusted to be steady through four nuts. The loaded and unloaded long material is guaranteed not to lose weight or to be out of balance, and efficient and safe production is guaranteed. The eccentric jack is simple and practical, low in cost and worthy of wide-range application.
