Inside fold, scroll wheel are taken advantage of a situation and are internally rolled, and buckle hasp；Some ordinary articles of courier can be placed in storage box；
Followed by the flexible contraction of integral body, first open in the Quick Release connection between the pipe of top four and the pipe of lower section four
Part then presses the spring pressure bar positioned at complete machine the top, and compression bar can drive the small pipe in pipe, will be located at the pipe hole that is nested
The V-type spring leaf at place is to contract, so that being nested in internal pipe and square tube under the effect of gravity to whereabouts, and position
In top upper rack posts whereabouts synchronous with sprocket wheel, the tensioning of the chain is remained after lowest part is fallen on, closes Quick Release connector, is protected
Hold tightening；Finally, by balladeur train to cat ladder operative gear, regulation motor rotation by the support of climbing ladder apparatus stock adjust to
Farthest position from the ground is kept without impinging on bottom surface, completes complete machine storage.
Second step is launched into use state by the truck stored, and with reference to the process of upper step and converse, first carries out whole
The elongation expansion of body fuselage, by spring force, compression bar sub bar no longer makes V-type spring leaf generate inside deformation, V-type spring leaf
Restore to original state, pull up four pipes that are nested, in the outside of upper and lower round bar there are two the device of limiting anti-rotation, anti-rotation value
Be limit two be nested round bar rising process rotate, fallen to prevent V-type spring leaf ball less than in corresponding hole, limiting refers to
So that mutually putting on pipe is pulled to corresponding position, to ensure that ball enters at the hole of two bars, top upper rack posts are synchronous with sprocket wheel
Rise, ensure the tensioning of the chain；Then heel brace to be opened, idler wheel is taken advantage of a situation to be rolled to outside, two connectors of connecting rod heel brace,
With hand, a top, heel brace are fixed outward；Hasp is opened, lifting table plate is put down；When needing using elevating function, by changing
Balladeur train is allocated to the gear set of elevating function, lifting chain, so as to which lifting table plate rises under the drive of chain by blocking means
Drop；When needing using cat ladder function, balladeur train is allocated to the gear set of cat ladder function, so as to which double leval jib be driven to realize support ground
Cat ladder movement afterwards.
