My framework for 6m working height is easily established or terminated within 15 minutes. Two holes for locking pins (to back up the pipe joints) were not accurate (about 3mm "next" drilled) and had to be corrected, that is expanded, be. Otherwise all the parts fit very well, the structure description was easy to understand and good editorial. The base members (rollable base frame) can be changed by extendable parts in Aufstelltiefe. For large working height is necessarily to think of stabilizing rods with which the scaffold can also be reliable and secured against falling and sideways "warping". The roles of the base parts are provided with good acting parking brakes, the wheels themselves are working properly and smoothly. Facit: am absolutely satisfied and no longer give it her :)
