平顶链具有结构简单、重量轻、制造和维修方便的优点。平顶链的顶板为输送物料提供了一定宽度的水平承载面。顶板宽度按输送物料的要求确定。链条与链轮啮合时，铰圈本身就是与链轮啮合的部位。因平行排列的顶板链两侧间隙小，所以，只能作直线移动。就用平顶链时正确定装十分重要。广泛应用于直行板链输送机的设计。多条并列的链板输送机可用采用网带输送机来代替。
The flat top chain has the advantages of simple structure, light weight, convenient manufacture and maintenance. The roof of flat top chain provides a certain width of horizontal bearing surface for conveying materials. The width of the top plate is determined according to the requirements of conveying materials. When the chain is engaged with the sprocket, the hinge ring itself is the meshing part with the sprocket. Because the gap between the two sides of the parallel roof chain is small, it can only move in a straight line. When using flat top chain, it is very important to fix it correctly. It is widely used in the design of straight plate chain conveyor. Several chain plate conveyors in parallel can be replaced by mesh belt conveyor.
板链输送机适用于形状不规则物品的重载输送。链条选用空心大辊子带附件链条，在两侧同步链条的附件上用板状构件连接使输送方向形成连续的平板，因而运行平稳。该机与链式或辊筒输送机配合使用可实现转角输送。
The plate chain conveyor is suitable for heavy load transportation of irregular shape articles. The chain adopts hollow large roller with accessory chain. The accessories of synchronous chain on both sides are connected with plate-shaped components to form a continuous flat plate in the conveying direction, so that the running is stable. The chain conveyor can be used together with the roller.
