Preferably the equipment comprises a platform 8 for a camera and a counterweight 10. The assemblies are positioned using a single remotely operable climber which can have a carriage and traction motor (8, Fig 6) or skate (66, Fig 13) on one side and a plurality of spring-pressed arms (10-14, Fig 6 or 70-76, Fig 13) on the other allowing the climber to the easily applied to or removed from a pole. The traction unit preferably comprises wheels gripping the post. The ends of the arms are also provided with rollers. |
