establishment and mechanics to house a boom extension

摘要

a fahrkran has a telescope hauptausleger from several sections and with the tip of the hauptauslegers revolving the boom extension.the boom extension can hand horizontally between a gebrauchslage they are in axially from the top of the hauptauslegers from covers, and a unterbringungslage, in which it is parallel to the hauptausleger along its side and body, gently.a front and rear unterbringungsmechanismus for boom extension is attached to the boom extension, solvable in the unterbringungslage. the first mechanism has two vertikalabstand ordered unterbringungsstifte in tubular stiftfu00fchrungen verschieblich, in a seitenflanke of hauptauslegers are appropriate.the unterbringungsstifte are verschieblich forward and back by an angle lever is movable, with which they are linked to traverse.the unterbringungsstifte move in and out of interference with a couple with vertikalabstand positioned, oriented pen - eingriffslu00f6cher in a part at a facing side of the boom extension is appropriate if the unterbringungslage is located.the lever is not only possible, but also axially in a sperrlage and from this verschieblich and is against the sperrlage charged to the solving of the lock as a result of shocks to prevent. the rear...
