Abstract

The manually propelled trolley is used to mount a pneumatic road drill (1) or similar, and has two pairs (4, 5) of perpendicularly orientated and vertically offset wheels. It has a torsion sprung swivel handle bars for improved insulation. A base cradle (3) locates the wheels and the foot of a two piece (6, 7) mast. The mast houses a simple jack, with the drill being strapped (11) to the top mast section (7) with its handles (13) located by two hook brackets (12). A short arm (14) cantilevers from the mast to locate a pivotable 'U' shaped frame (16) on which the handles (17) are mounted, the frame pivoting about an axis (13) through the bar.
