Claim 21:
22. A vehicle displaceable along aerial conductors of an electricity transmission line, the vehicle comprising:
a body having at least one pair of arms, the arms of the at least one pair of arms being mounted on opposite sides of the body and movable part from one another, each said arm having a first end pivotably mounted to the body and a second distal end, a wheel being mounted to the distal end of each said arm, each said wheel being engageable with one of the conductors to displace the vehicle therealong, at least one of the arms being motorized; and
a plurality of support rotors each mounted with one of the wheels and provided with at least two blades, each said blade having an arm portion extending from the support rotor and being rotatable therewith, and a contact portion extending from the arm portion to engage one of the conductors to temporarily support the vehicle with the contact portion, the at least two blades including an impact blade and at least one transition blade, the contact portion of the impact blade has a shape different from a shape of the contact portion of the at least one transition blade, the one of the wheels being rotatable about a wheel axis, a plane being defined normal to the wheel axis, a first angle defined between the plane and the contact portion of the impact blade different than a second angle defined between the plane and the contact portion of the at least one transition blade.
