Палец шкива стрелы с увеличенным вылетом, диаметр 44,85 мм Caterpillar 6087406

An Extension Boom Pulley Pin acts as the central axis on which the pulley rotates. It provides a smooth guiding point that allows the pulley to turn freely under load. By keeping the pulley rotation controlled, the pin enables ropes or cables to move without excess friction. This function reduces stress on the pulley and ensures consistent transmission of pulling forces. The pin also contributes to balanced load distribution across the pulley, which supports reliable mechanical function under repeated cycles of lifting and extension.Attributes:• Supports smooth transfer of pulling forces.• Serves as the axis for pulley rotation.• Ensures stable turning under load.Applications: An Extension Boom Pulley Pin is located within the boom extension system, where it holds the pulley in place to allow smooth rope movement.
