Selection needs more than kilograms.
Two payloads of the same mass can have different centres of gravity and inertia. The distance from the axis changes the moment and structural assessment. An equipment drawing or dimensioned photograph supports the initial review.
Define travel and cable clearance together.
Even with a −40° / +40° tilt target, the equipment envelope and cable bends can constrain usable travel. Limited pan motion and continuous rotation should be distinguished at the start.
A moving platform is a separate operating scenario.
Positioning on a fixed base and maintaining a line of sight on a moving platform have different scopes. Base motion, vibration, sensing needs and control objectives must be defined; stabilisation requires separate validation when requested.
Agree acceptance criteria before quotation.
Speed, positioning, communications, protection and temperature requirements follow the operating scenario. Agree which tests will be performed with which payload and environment; targets should not be presented as test results.
