用这种支架时，辊子安装完毕需用钢丝进行锁紧（即相邻3～5个辊子轴用钢丝串在一起）。辊子Φ155的支架采用槽钢，辊子轴用压板和螺栓固定在槽钢翼缘上。

When the bracket is used, the roller is installed with the steel wire to be locked (that is, the 3~5 roller shafts are strung together with steel wire). The support of the roller 155 is used in the channel steel, and the roller shaft is fixed on the flange of the channel steel with the press plate and bolt.

双层滚筒输送机同样也具备了滚筒的优点。具有输送量大，维护方便等原因。应用于各行业的成品包装箱、周转箱等输送。要求被输送物的底部是平整的。而且每三只滚筒要与底部接触。

Double drum conveyor also has the advantages of drum. It has a large amount of transportation, convenient maintenance and so on. It is applied to the transportation of finished packing boxes and turnover boxes in various industries. The bottom of the conveyer is required to be flat. And every three rollers should be in contact with the bottom.

链板输送机以标准链板为承载面，由马达减速机为动力传动；我们可以通过多列链板并行，使链板输送机做的很宽并形成差速，利用多列链板的速度差使多列输送在无挤压的情况下变为单列输送。

The chain plate conveyer takes the standard chain plate as the bearing surface, and the motor reducer is driven by the motor. We can make the chain conveyor be very wide and form the differential speed through the multi chain chain plate.
