Abstract
A mobile crane having a telescopic jib 15 which is mounted on an upper chassis 8 has a cantilever counterweight 14 and an additional removable counterweight 27. The additional counterweight 27 is carried on a holder 28 which is mounted on a strut 21 which is directly pivotally connected to the jib 15. The strut 21 can be pivoted to raise and lower the holder 28 to enable the additional counterweight 27, which is removable, to be picked up and deposited. The additional counterweight 27 is deposited and removed to lighten the crane for road travel, but when operative, increases the lifting capacity of the crane.
