The mobile telescopic crane by chief executive Colin Wood
In dark and distant days, mobile cranes all used lattice boom sections.
Companies would hire out 6-ton cranes with 17-metre booms. Jib sections - stacked either side of the crane had to be first lowered to the ground with a davit arm in order to connect them together while larger cranes needed articulated lorries to carry additional jib sections.
In 1967 everything changed with the advent of the mobile telescopic crane. The principle is straightforward: The first base section is pivotally mounted on a crane carrier and a second box section is telescopically engaged with the base section with a drive piston and cylinder arrangement to extend the boom.
Today mobile telescopic cranes can be mobilised quickly Ð they usually require just one operator and one support vehicle to be up and running. Furthermore, the telescopic arm means that you donÍt have men working at height connecting parts together.
