The clamp halves (1) are fixed to arcs (3) for forming the sides. Between the sides are rotatably located support rollers and an openable component (7). The sides can be clamped against the insulator throat, each clamp half is laid against the insulator throat and all clamping effect is directed to the insulator. The arcs are made of tubes or round bars and are formed like a semi-circle or triangle, with their bases firmly connected to the clamp halves. The axles (13,14) of the support rollers (5,6) do not serve to hold together the line carriage. Between the tops of the arcs is located the openable component in the form of a slide rail (7). The support roller (5,6) axle lines are at a distance from one another corresponding to at least 6-7 times the support roller smallest diameter. |
