A ladder jack scaffold isa simple device consisting of a platform resting on brackets attached to a ladder. Ladder jacks are primarily used in light applications because of their portability and cost effectiveness.
As of November 18th 2036, cages will no longer be accepted as a form of fall protection, and all fixed ladders taller than (or that extend beyond)24 feethigh must use a personal fall arrest system or a ladder safety system.
A ladder isa vertical or inclined set of rungs or steps commonly used for climbing or descending. There are two types: rigid ladders that are self-supporting or that may be leaned against a vertical surface such as a wall, and rollable ladders, such as those made of rope or aluminium, that may be hung from the top.Ladders are used to access areas of height with limited body movement as it compromises the stability of the ladder. Whereas with a scaffold tower you can move around more freely with a fixed structure for solid footing. Hence you can work for longer periods of time than on a ladder.fixed ladders taller than (or that extend beyond)24 feethigh must use a personal fall arrest system or a ladder safety system.The word "ladder"comes from the Old English word "hlæder" which itself is derived from the verb "hlaiþan" meaning "to climb". If you trace the word even further back, there are links to the Proto-Indo-European root "klei-" meaning "to incline" or "to lean".
