Giant Pontoon Crane
This model started life as Meccano Limited’s 1968 Meccano Magazine rebuild of the 1930s model. This uses a GRB in its construction, and is powered by an E20R motor.
The gearbox is modified to slow the motions down as the builder feels they are too fast to be realistic. The jib luffing is screw operated and alos has two independent load hooks. The superstructure will rotate 360 around the base as well.
