水平调节支撑脚轮

 

GD 系列 使用方法和差别 (The difference & how to use of GD-series)

GD 系列表示法 (Numbering system of GD-series)
GD

水平调节支撑型机器 脚轮 (Leveling caster with manual handle)

GDN

新型 水平调节支撑型机器 脚轮
(New type leveling caster with manual handle)

GDR

棘轮气扳机型水平调节支撑型机器脚 轮
(Leveling caster with ratchet handle)

Mounting S

丝杆型 (Stem type mounting)

F

底板型 (Flange type mounting)

E

表示例 (For example)

■GD系列允許负载( Load capacity of GD-series)
N

所需脚轮数量 (Number of casters)

W

设备或大车的净重 (Weight of equipments or carts)

Wa

积载负载 (Additional charge)

Wc

脚轮的允许负载 (Allowable load of caster)

S

安全系数 (Safety factor)
设备适用 ( For equipments), S : 2.0

计算公式

型号选择例
(For example)

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 2.0

GD-60 适用时 (For GD-60)


GD-80 适用时 (For GD-80)

∴ 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.
