常见挂车的类型简介及使用
半挂车是一种无动力、可独立承载的道路车辆，需与牵引车车头配合才能正常使用，主要用于货物运输及其他特种用途。那么， 半挂车有哪些不同类型 ？哪种挂车最适合你？它们之间有什么区别？请看以下不同类型的半挂车：
一、平板式挂车
平板式挂车分为直梁半挂车和鹅颈半挂车，承载部分均为无栏板结构。
用途：此类车型适用于运输钢材、石材及水泥等货物，应用广泛，主要适合中重型及散装货物的中长途运输，适应性强，已成为中长途货运车辆的首选。
特点：两种车型的区别在于第二种为鹅颈式结构。
优点是更低的载荷面和更低的重心。驾车拖挂时转向更舒适，过桥的通过率也较高。
1. 车身采用高质量钢材，工艺先进，生产严格。整车结构合理、性能可靠、操作简单、外观美观。
2. 系列拖车的车架为贯通梁结构。纵梁采用平型和鹅颈型。焊缝由锰板从 400mm 至 550mm。纵梁采用自动埋弧焊，车架进行喷丸，横梁穿入纵梁并整体焊接。
3. 悬挂采用非独立钢板冲压式刚性悬挂。由系列板簧与悬挂支撑组成。结构合理，刚性和强度较强，用于承载与减缓冲击。
II. Bin rail trailer
Bin rail trailer is divided into straight beam bin rail and gooseneck bin rail. It is a semi trailer with a detachable guardrail at the loading position. It is a semi trailer with a fence structure design at the loading position.
Purpose: It is mainly used for transportation of agricultural and sideline products and other light foam goods.
1. Vehicle type and fence structure design process is combined with goods category of users. It is a rational design. It fully reduces the weight of the car under load. The structure is simple and applicable, and it is easy to disassemble. It reduces the investment cost and creates more profit value for users.
2. Frame: it is a space frame structure composed of longitudinal beam and integral through beam. It can balance the strength, rigidity and toughness of the frame, with strong bearing capacity and there is no permanent deformation.
