<p>A means for mounting an auxiliary device, of the adjustable bracket crane type, on the platform of an elevating truck has the advantage of being adaptable to this platform without bolting and of permitting the shaft of the bracket crane to be rotated through approximately 180 degrees. The platform (2) of the truck comprises two parallel bars (5, 6) forming a sliding block for a truck derrick. The support (7) comprises an upper plate (70) pierced by an aperture (73) for the passage of the shaft (80) of the bracket crane (8) and in which is provided a groove (74) interacting with a rib (50) on the upper bar (5), a plate (71) at a right angle with the upper plate (70) engaging to support two stops (61, 62) on the lower bar (6), and a seating (72) accommodating the foot of the shaft. This means permits loading and unloading with no external assistance, no visit to a specialised workshop and no delays. <IMAGE></p> |
