What type of Bolts used in mobile telescopic crane?
I am not sure what you mean, but I hope that help you A counter-jib on which ballast can be hung and a hydraulic ram which can swivel said counter-jib both being falcrumed on a supporting frame. The frame is bolted at at least two connecting points to the rotating deck in such a way that after the creation of the bolt connection located in the area of the fulcrum part, the other connecting point of the bolt connection can be swivelled at its bolting position on the rotating deck by luffing up the retracted jib. The mobile crane in accordance with the invention possesses as an additional piece of equipment a counter-jib whose installation allows said mobile crane to be converted into a derrick cranewith a very much higher lifting capacity. To install the counter-jib, it is placed by an auxiliary crane onto the retracted telescope jib lowered onto the vehicle in such away that the supporting frame of the counter-jib can be bolted to the rotating deck at a connecting point located on the rotating deck in the area of fulcrum ofthe fulcrum part of the telescoping jib. Subsequently, the counter-jib is lowered by the auxiliary crane fully onto the fulcrum part, the counter-jib being supported on the fulcrum part by means of a supporting shoe or supporting device which can slide on the fulcrum part or the counter-jib. Then the retracted sib is luffed up by its luffing ram until the second connecting point of the supporting frame has been swivelled into its bolting position on the rotating deck so that in this position the supporting frame can be fully connected to the rotating deck by means of bolting. After such bolting, the counter-jib can be swivelled backwards so that crane operation can begin once the holding rope or adjusting rope has been reeved and the ballast hung on.
