Aluminum alloy ladder buy practical skills

通常市面上出售的梯子,光从外表看,可能有些不太好分辨,但是光泽和质感也可以看得出来一些.最好的分辨方法亲手触摸一下,以下的几个方法供您参考.

Usually the sale of the ladder, light from the appearance, there may be some not so good resolution, but the luster and texture can also see some of the best resolution method. Hand touch, several following methods for your reference.

1.梯子材料辨别

1 ladder material discrimination

一般可以通过材料查看型材表面的光泽度来判断，如果是选用回料做出来的梯子表面程暗沉或惨白，没有光泽度（基本不反光）, 触摸手感比较粗糙，新料做出来的表面光泽度非常好，触摸手感比较光滑细腻；还有可以看下材料的韧性，合格的铝合金材料应该是在受到允许外力的挤压后，能马上恢复原状，如果不能马上恢复，那么这种梯子就存在很大的安全隐患。.

General can be judged by the material view profile surface gloss, if is the ladder surface process using feed back made out of dark or pale, no gloss (no light), touch feel rough comparison, surface gloss of new material made out of very good touch feeling, smooth and delicate; also can see the toughness of the material the aluminum alloy material, qualified should be allowed by outside force, can immediately recover, if not immediately resume, then this kind of ladder is a lot of potential safety problems. .

2.梯子的做工:

The work of 2 ladder:

首选打开梯子看一下,如果梯子一打开就吱吱吱的响声,绝对不是好梯子.好的梯子打开合闭时,都是没有声音的， 梯子打开时,水平能否放正,如摇晃,检查下是或有长短脚，也可查看配件的用料和做工精细度，最后梯子接口处好坏判断如下：

First open the ladder to see, if a ladder opened creak creak sound, is not a good ladder. Good ladder open closed, there is no sound, the ladder is open, can put it, such as shaking, check or leg length, can also see parts of the material and fine workmanship degree, finally the ladder interface judgements are as follows:

a.接口固定方式铆钉铆接的，可以看下铆钉的加工状态,如果有松动或间隙过大,属于不合格品；

A. interface fixing rivets, rivet can see processing state, if there are loose or gap is too large, which belongs to the unqualified products;

b.接口固定方式焊接的，焊道一定要为鱼鳞片状样为标准品，而且焊道要饱满高度大小要均匀一致；

B. interface fixed welding, weld must be fish flake like as the standard, and pass to the full height of uniform size to;

c. 接口固定方式为压铆的，可以看下踩杆与梯梁连接处是或有松动（没压紧），踩杆翻边应大小均匀；.

The C. interface is fixed for pressure riveting, can see on the rod and the ladder beam joint is loose (or no compression), treading rod flanging shall be uniform;.

3.检查一下承载力:

The bearing capacity of the 3 inspection:

为了防止质量不好的梯子在检查承受力时使我们受伤,我们先要看一下标识最大的承受力是多少,在承受力与体重相合适用时,可亲身检验.，但不能一下子加重,需要在可承受时再加一些重量测试，在梯子国标GB 12142-2007中载荷可分为四个档，分别为90KG、100KG、110KG、135KG，合格的梯子安全载荷应该是标识的2.5倍以上。

In order to prevent poor quality ladders in the inspection capacity when hurt us, we should first look at the mark what is the maximum capacity, the endurance and weight matched when applicable, to test., but not all of a sudden increase in affordable, need to add some weight to the test, in a ladder GB GB 12142-2007 load can be divided into four files, respectively 90KG, 100KG, 110KG, 135KG, ladder safety load qualified should be more than 2.5 times mark.

以上这些希望对您购买梯子有所帮助，也希望如果您有更好的经验和建议也可以我们一起分享
