Safety: what safety systems are implemented in JoyMechanix cable cam systems?

This article explains the safety approach inside JoyMechanix systems, including the three safety layers, how emergency stop behavior is implemented at the system level, and how 3D safety zones support safer operation near obstacles. It is an overview of system features and operational concepts - it does not replace venue-specific risk assessment, structural engineering approval, rigging method statements, or local compliance requirements, which must be defined per site and production.

Our systems use a three-layer safety architecture designed to provide one of the highest levels of operational reliability on the market.

The first layer is software-based safety control.

The software continuously monitors more than 40 parameters for each winch and system component. This includes:

If any abnormal behavior is detected, the system automatically performs a controlled and safe stop.

The second layer is operator-controlled safety.

The operator interface continuously displays critical operational information and warning notifications. The pilot always has access to an emergency stop function capable of safely stopping all winches and equipment immediately.

This ensures that the operator remains fully informed about system status during operation.

The third and most advanced layer is an independent electronic safety circuit operating separately from the software environment.

This circuit continuously:

• checks software and Control Station activity,
• monitors structural integrity of control cables,
• supervises winch operation independently from the main controller.

Because this layer operates electronically and independently from software processing, it reacts almost instantly.

For example, if:

• a control cable is disconnected,
• power is lost,
• or communication with a winch fails,

the electronic safety layer immediately locks system operation before the software even begins analyzing the issue.

This creates a highly redundant safety architecture and significantly reduces risks associated with software-only protection systems.

Our systems include the most advanced three-dimensional safety area functionality.

Operators can create complex safety zones around:

• ceiling structures,
• lighting systems,
• walls,
• ground objects,
• and other obstacles inside the working area.

Instead of applying a hard stop when approaching the limits, the system automatically calculates smooth trajectories around restricted areas.

This means:

• the camera can smoothly slide along the virtual safety boundary,
• high-speed movements are safely slowed down,
• and operation remains stable and fluid even near the edges of the working zone.

This greatly improves operational safety while maintaining cinematic camera movement quality.

The system has undergone third-party testing and certification. During testing, the system completed multiple movements along a 1.5-kilometer trajectory and over 400 motion cycles. The positioning accuracy at any stage of the movement was only 1.5 mm!

This level of accuracy provides extremely high confidence in repeatable motion control operation.
