Climbing DevicesSource: Winola Industrial, Inc.
Our ladders are ideal for use on steel and concrete poles, towers and any other application where "bucket" trucks and other conventional climbing methods won't work, or need to be supplemented.
These sectional pole ladders provide increased versatility, economy and security, as they can be left in place for permanent access, or removed from the structure when your work is done.
The common Industry-Standard designs are the Climbing Ladder, with 4 step bolts, which are staggered for climbing, and the Working Ladder, with 8 step bolts, which are adjacent, for working.
Standard ladders are attached to poles or other structures by clips. The most common clip placement specification is sometimes referred to as "odd" spacing - clips are located in pairs spaced 13 1/2" apart, with 3' - 10 1/2" spacing between the pairs.
Alternately, clips may be spaced "even", with one clip being placed every 2'-6".
The use of clips allow the ladder to be slid into place, then a set screw on the ladder "shoe" or "foot" locks the ladder into position. They also allow manufacturers of structures to utilize a simple process of attaching very inexpensive ladder clips at their plant. This is often seen as a preferable alternative to the labor-intensive processes involved in fabricating and handling ladders or other types of climbing apparatus for each structure they make.
When installed, the ladders form a continuous run up the structure. Clips can be placed in any location, at low cost, allowing the end users the option of installing ladders to perform maintenance only if needed, or permanently mounting the ladders so access is always available. For security, the first few ladders closest to the ground can be removed when work is done to prevent unauthorized persons from climbing the structure.
