Aluminum ladder, while using mode of operation,is Classified into folding ladder and extension ladders(Second, upgrading ladder, three moving up ladder, double lift, two-dimensional transform ladder, three-dimensional transformation ladder).
Inside Aluminum ladder,the mode of operation about Folding ladder is really as follows:
1.Locked Expand the Aluminum ladder column. Hear the "click" sound simultaneously lock the block on the "L" position. This position have been locked hinge.
2.Unlock Pulled the handle to open the lock as you move the lock block to retreat into "O" position, said hinge is unlocked, then you can definitely affect the angle relating to the Aluminum ladder or Aluminum ladder column.
* In the event of pull the handle won't move, are unable to unlock , which can be due to compression force live hinge lock block, then you can pull Staircase shake to discharge the external force (Figure 9)
3.Check After continuing development of their state to implement an Aluminum ladder, please carefully verify that all hinges come in a locked state "L" ,then it may be employed. Should you have locked the present state from the end of "O" hinge. Symmetrical hinges is usually opened. Ladder column and then inward about 40 degrees. And then expand outward so your hinge is usually locked.
4. Note
a. Length lower than or corresponding to 4 m ladder use can be expanded into a straight ladder. At this time the angle between the Aluminum ladder and the ground need to be bigger than 75 degrees. Center of the Aluminum ladder hinge should face the wall. (Figure. 10)
b. Sizhe be used as a platform ladder, confirm the thickness with a minimum of 1cm flat pad (Figure. 11)
c. When someone is employed in the Aluminum ladder, others is strictly prohibited to pulled the hand and alter the lock status of the hinge. (Figure. 12)
