Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standar
ds bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be reprented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates cloly with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
国际标准化组织（ISO）是由各国标准化团体（ISO成员团体）组成的世界性的联合会。制定国际标准工作通常由ISO的技术委员会完成。各成员团体若对某技术委员会确定的项目感兴趣，均有权参加该委员会的工作。与ISO保持联系的各国际组织（官方的或非官方的）也可参加有关工作。ISO与国际电工委员会（IEC）在电工技术标准化方面保持密切合作的关系。
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
国际标准是按照ISO / IEC导则第2部分给出的条例起草的。
The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publi
cation as an International Standard requires approval by at least 75 % of the member bodies casting a vote.
该技术委员会的主要任务是制定国际标准。国际标准草案通过技术委员会分发给成员机构进行投票，作为国际标准的出版物至少需要75%成员投票通过。
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

3 Jockey wheels – requirements \支撑轮—要求
3.1 Markings \标识
Each jockey wheel must be permanently and clearly legibly marked with the following information on a non-removable component:
泰国有几个机场–Manufacturer's identification;
–Load lifting capacity
每个支撑轮必须在不可移动的部件上永久明确的标记出以下内容：属虎的属相婚配表
--制造商的厂家标识
水下写真
--支撑重量
和雨有关的诗句3.2 Testing \ 测试
Test load = 2 x permitted load lifting capacity
测试载荷=2×允许的支撑载荷
Test parameters \ 测试参数：
●Secure the screw-mounting plate or clamping retainer to the test rig.
螺纹连接部件或夹紧架通过测试后应牢固可靠。
●in the ca of a clamping attachment, curely clamp the jockey wheel in the centre of the clamping
range.
对于加紧附件，其应安全地夹在支撑轮夹紧范围的中心
●Crank up the jockey wheel to the maximum lifting height specified by the manufacturer.
支撑轮通过转动摇柄能起升的最大高度由制造商指定。
●Select an unfavourable position for the wheel, i.e. at the forward end of the clamping attachment /
fastening plate turned away.

当应用测试加载荷后，支撑轮不应有移动。
Test result\试验结果:
When the testing force is discontinued, no visible damage or distortion must be prent. Further troublefree functioning must be assured. Jockey wheels must safely absorb the test load without lowering unintentionally.
当试验力中止，支撑轮没有明显的损坏或变形，功能完全正常，能安全承载不低于实验载荷的力。

在额定载荷下，转动支撑轮摇柄的力不超过250N
It must be possible to effect the clamping force required to reliably ensure a friction locked fastening of the outer tube by manual effort.
