设备适用 (Application : For equipments)
W |
600 Kg ( 设备净重 ) |
Wa |
50 Kg ( 设备的积载负载 ) |
Wc |
250 Kg/pce (GD-60), 500 Kg/pce (GD-80) |
S |

∴ N ( 所需脚轮数量 ) : GD-80 4 ? (4 pcs for GD-80 ) |
注意 (Remarks) |
设备负载將超过四个脚轮的适当负载限度时,由于四个以上安装也承受不了负载,应安装上一个阶段的模型。但是,比较特殊的设备可以在不超过每四个允许负载的范围內,追加安装。
In the case of the heavier weight of equipment than the recommended load capacity per 4 pieces, the higher range model of FOOT MASTER should be adopted. It means more wheels than 4 pieces are not assumed to maintain the equipment weight because the weight of equipment is not usually distributed to each wheels identically and simultaneously. (But more wheels may be adopted within the recommended load capacity per 4 wheels. |
