<p>The application is to cable trolley systems for the support of control cables or similar light wiring. The trolley comprises an upper part (21) which slides along the carrying rail, and has two downward facing limbs (211, 212). The inner face of each limb is grooved (213) and these grooves mesh with corresponding ones (222) in the arch shaped calbe support (22). To adjust the position, or insert or remove the lower part, the limbs are sprung apart. When released again they grip the lower part holding it in position and giving secure support to the cables. Installation in overhead locations is eased by the elimination of nuts and bolts offered by the design.</p> |
