Load Capacity Range for Pan and Tilts
When selecting the right pan and tilt unit for your heavy-duty subsea or topside application, understanding the load capacity is key. Models across the industry, including robust builds from leading manufacturers, span a wide range to suit various operational demands.
Lower Capacity Units:
Some large-format pan and tilt assemblies are rated for loads as low as 20kg, suitable for lighter equipment or specialized positioning where agility is needed.
Mid-Range Workhorses: Stepping up, many heavy-duty units comfortably handle up to 50kg, striking a balance between strength and versatility – ideal for standard underwater cameras or lights.
Higher Capacity Solutions:
For more demanding jobs, heavyweight pan and tilt devices boast capacities from 80kg to 100kg, ensuring stability for sizable payloads or complex instrumentation arrays.
Maximum Load Models:
Top-tier assemblies push the envelope even further, with premium options built to manage up to 150kg. These are engineered for large sonar systems or multi-sensor platforms where reliability and muscle are non-negotiable.
The available SIDUS pan and tilt systems cover a comprehensive range – whether you need the nimbleness for moderate loads or the unwavering durability to handle the heaviest equipment, we have a solution ready for the job!
