Safety and conductor integrity are paramount. Modern power lines stringing machines incorporate numerous features to ensure both:

• Precise Hydraulic Control: Offers incredibly smooth and infinitely variable control over pulling force and tension. This prevents sudden jerks, over-tensioning, or slack, which can damage conductors or endanger personnel.

• Automated Overload Protection: Integrated sensors and software continuously monitor tension and pull force. If pre-set limits are exceeded, the machine automatically adjusts speed or safely stops, protecting both the conductor and the equipment.

• Fail-Safe Braking Systems: Robust, often multiple, braking systems (e.g., negative hydraulic brakes, disc brakes) automatically engage in case of power loss or emergency stops, securely holding the conductor in place.

• Remote Control Capability: Many machines offer wired or wireless remote control, allowing operators to manage stringing operations from a safer vantage point with enhanced visibility of the entire stringing path.

• Bullwheel Design and Material: Bullwheels (or capstans) are designed with large diameters to minimize bending stress on conductors and are lined with non-abrasive, high-friction materials (e.g., specialized rubber, polyurethane) to grip securely without causing surface damage.

• Synchronized Operation: When pullers and tensioners are used together, modern machines are designed for synchronized control, ensuring consistent tension across the entire span and preventing differential speeds that could lead to conductor snags or damage.

• Safety Guards and Emergency Stops: Prominent emergency stop buttons, protective guarding around moving parts, and clear safety markings are standard.
