The original design for this type of pan and tilt head dates back over many decades, with the earliest models being responsible for engineering more than a few hernias in their time. Given that 1” format tubed cameras were big, and the motorised zoom lenses used on them could be huge, that meant the weatherproof housing had to be absolutely enormous just to fit everything in. So with overall assembly weights frequently in the twenty to thirty kilogrammes range, the pan and tilt head had to be a real bruiser just to hold its own. With maximum weight capacities of around 50Kgs. these torsional leviathens were not to be taken lightly!! The idea of side mounting the housing assembly, meant that there was effectively unrestricted movement, although the fact that the weight distribution was offset from the centre of gravity, could in itself cause interesting For about twenty years or so, this standard side mount configuration reigned supreme, although towards the end of the 1980’s, the Over the Top (OTT) configuration started to grow in popularity. That aside, their is still a comprehensive range of units being built for both indoor and outdoor use, with load capacities ranging from 1.5 up to 50 Kgs. Predictably, the majority of pan and tilt heads now built are of the OTT type, as shown in the picture above. | ||||||||||||||||||||||||||||||
