Further, described cat ladder rod end is provided with hook member, and described hook member is arranged on cat ladder rod end by casing joint. Hang on metope purlin by hook member, to prevent cat ladder from toppling over temporarily; Operating personnel can be freely upper and lower at vertical metope by ladder step, simultaneously as operating platform, it is simple to encaustic tile is installed.
Further, cat ladder vertical rod head and the tail two ends described in two sets are telescopic joint by double end, according to actual needs, it is possible to increase the length of cat ladder, mainly adopt the cat ladder that two sets are made up of cat ladder vertical rod, cat ladder stull and arm-rest frame, connected by double end sleeve pipe is fixing by cat ladder vertical rod head and the tail two ends.
Further, described cat ladder stull two ends all correspondences are connected to handrail stull. Rotary folding can be realized realizing the pedal in every cat ladder stull.
The present invention compared with prior art, has such advantages as and beneficial effect:
1, it is respectively equipped with hook member at safety climbing ladder top and bottom and supports leg piece, it is possible to effectively preventing cat ladder lower slide, it is prevented that cat ladder upper end tilts, and adds the safety of cat ladder;
2, adopt to overlap the cat ladder being made up of cat ladder vertical rod, cat ladder stull and arm-rest frame more, connected by double end sleeve pipe is fixing by cat ladder vertical rod head and the tail two ends; According to actual needs, it is possible to increase the length of cat ladder;
3, it is provided with arm-rest frame and pedal, arm-rest frame is set on the one hand and pedal is easy to operating personnel's climbing, it is prevented that operating personnel falls, on the other hand, it is possible to achieve arm-rest frame and pedal linkage fold, and conveniently transport and deposit.
