Support device for carrier frame for lifting work platform has extendable support whose extension length is limited to prevent overloading of lower load introduction blocks with internal support girder end

摘要

Lower load introduction blocks (5) are disposed between the lower side (2.2) of an extendable support (2) and the inner side (3.5) of a hollow carrier (3) such that the lower load introduction blocks are firmly arranged on the carrier. The extension length of the support is limited to prevent overloading the lower load introduction blocks with the internal support girder end. The extendable support projects from the carrier and is propped up at one end by a height adjustable support (1). Upper load introduction blocks (4) are disposed between the upper side (2.1) of the support (2) and the inner side (3.4) of the carrier.
