Claims25
A remotely-controlled manipulator for mounting to the end of a telescopic boom, comprising:
- at least one releasable support mounted to a cross member for releasably holding an elongate object.
A remotely-controlled manipulator comprising at least one releasable support mounted to a cross member for releasably holding an elongate object, said cross member mounted to the end of a telescopic boom.
A method for replacing the cross arm of a power line tower comprising the steps of:
- a) providing a remotely-controlled manipulator which includes at least one releasable support mounted to a cross member for releasably holding a replacement cross arm adjacent said cross member, wherein said cross member is pivotally mounted by pivotal actuating means to the end of a telescopic boom for pivotal movement by actuation of said pivotal actuating means in both a vertical plane and a horizontal plane relative to said boom,
- b) releasably mounting a replacement cross arm in said at least one releasable support,
- c) extending said boom so that said cross member is adjacent a cross arm mounting position on the tower,
- d) pivoting said cross member vertically so as to align horizontally said replacement cross arm, and between power transmission lines adjacent said tower,
- e) pivoting said cross member horizontally to swing said replacement cross arm into said mounting position and mounting said replacement cross arm to said tower.
