the mode of operation of Aluminum ladder Extension ladder
A Aluminum ladder known as Aluminum step ladder.Aluminum ladder's foot rod made of high strength aluminum, the surface has a non-slip tread stripes . Aluminum ladder's foot rod with a straight rod was connected using a special riveting process. Aluminum ladder consists of a combination of upper and lower section of ladder ,with the lifting hooks, pulley blocks and rope ladder down to the last section with ease. Aluminum ladder to the top with a hook, Safety and reliability.
Aluminum ladder, according to the mode of operation,is Classified into folding ladder and extension ladders(Second, moving up ladder, three moving up ladder, double lift, two-dimensional transform ladder, three-dimensional transformation ladder).In the Aluminum ladder,the mode of operation about Extendable ladder is as follows:
1.Single Aluminum ladder or extension ladder-type angle with the ground about 75 degrees to the vertical support points at the bottom of the ladder length is about one-fourth the working length.
2.After stretching Aluminum ladder. To maintain the minimum overlap part of the overlap distance should meet the right criteria.
Aluminum ladder folding ladder in the mode of operation compared to the use of extension ladders way is relatively complex. Must first determine if it is folded or extended type of ladder. Then with reference to its use. Correct and effective use of Aluminum ladder. The function of making Aluminum ladder play to the maximum. Aluminum ladder makes our right-hand man. Aluminum ladder make our daily work and life much easier.
