Aluminum alloy ladder buy practical skills
通常市面上出售的梯子,光從外表看,可能有些不太好分辨,但是光澤和質感也可以看得出來一些.最好的分辨方法親手觸摸一下,以下的幾個方法供您參考.
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.梯子材料辨別
1 ladder material discrimination
一般可以通過材料查看型材表面的光澤度來判斷，如果是選用回料做出來的梯子表面程暗沉或慘白，沒有光澤度（基本不反光）, 觸摸手感比較粗糙，新料做出來的表面光澤度非常好，觸摸手感比較光滑細膩；還有可以看下材料的韌性，合格的鋁合金材料應該是在受到允許外力的擠壓后，能馬上恢復原狀，如果不能馬上恢復，那么這種梯子就存在很大的安全隱患。.
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:
首選打開梯子看一下,如果梯子一打開就吱吱吱的響聲,絕對不是好梯子.好的梯子打開合閉時,都是沒有聲音的， 梯子打開時,水平能否放正,如搖晃,檢查下是或有長短腳，也可查看配件的用料和做工精細度，最后梯子接口處好壞判斷如下：
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.接口固定方式鉚釘鉚接的，可以看下鉚釘的加工狀態,如果有松動或間隙過大,屬于不合格品；
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，焊道一定要為魚鱗片狀樣為標準品，而且焊道要飽滿高度大小要均勻一致；
B. interface fixed welding, weld must be fish flake like as the standard, and pass to the full height of uniform size to;
c. 接口固定方式為壓鉚的，可以看下踩桿與梯梁連接處是或有松動（沒壓緊），踩桿翻邊應大小均勻；.
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.檢查一下承載力:
The bearing capacity of the 3 inspection:
為了防止質量不好的梯子在檢查承受力時使我們受傷,我們先要看一下標識最大的承受力是多少,在承受力與體重相合適用時,可親身檢驗.，但不能一下子加重,需要在可承受時再加一些重量測試，在梯子國標GB 12142-2007中載荷可分為四個檔，分別為90KG、100KG、110KG、135KG，合格的梯子安全載荷應該是標識的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.
以上這些希望對您購買梯子有所幫助，也希望如果您有更好的經驗和建議也可以我們一起分享
