ABSTRACT:
A tool balancing apparatus comprises a spring arrangement for balancing the weight of a tool such as an assembly tool. The spring arrangement is a hydro-pneumatic piston-cylinder unit whose one end is connected to a suitable mounting means and whose other end, being extensible, carries the tool. The apparatus further includes a bracing means such as a tube or a torsion bar assembly to form a rigid connection between the tool and the mounting means, thereby to carry any forces produced by the tool during operation thereof and to transmit such forces to the mounting means.
