Precision Braking for Industrial Motion Control

The TPK Foot Pedal Variable Frequency Controller is engineered for high-demand industrial applications, including crane slewing mechanisms and trolley drive systems. By integrating advanced frequency conversion technology with foot pedal input, the TPK controller enables precise, real-time modulation of braking force—delivering smoother deceleration and safer stops for heavy-duty machinery.

How it works

Unlike conventional braking systems, which rely on fixed or stepwise control, the TPK controller converts the amplitude of the foot pedal signal directly into a variable output frequency. This frequency is then used to adjust the speed and thrust of the actuator motor with precision, providing proportional and continuous control of braking torque. The linear relationship between pedal position and braking force enables operators to manage deceleration intuitively, thereby minimising shock loads and reducing wear on mechanical components.

Synchronised multi-drive control

The TPK controller supports multi-drive synchronisation, ensuring that multiple actuators operate in unison. This feature is essential for large-scale cranes and gantry systems, as uneven braking can lead to misalignment or structural stress. The TPK system distributes control signals intelligently to maintain consistent braking performance across all connected drives.

Technical specifications:

  • Operating temperature: -10°C to 40°C in non-corrosive, dust-free environments.
  • Power supply: 380 V, 50 Hz (industrial standard)
  • Duty cycle: S3-60% (intermittent operation)
  • Maximum cable length: 30 metres between controller and motor.
  • Application compatibility: Designed for integration with a wide range of industrial electromagnetic and hydraulic brakes.

Application Scenarios

  • Overhead and gantry cranes: Slewing, trolley and bridge drive braking.
  • Port equipment:
    • Container cranes
    • Ship unloaders
    • Heavy lifting machinery
  • Metallurgy and mining: High-frequency, heavy-load braking environments
  • Automated production lines: Systems requiring synchronised, multi-point braking control

Data-Driven Benefits

  • Enhanced Safety: Research indicates that variable frequency braking systems can reduce stopping distances by up to 25% compared to traditional fixed-control brakes, thereby significantly lowering the risk of accidents in high-mass applications.
  • Reduced Maintenance: The TPK controller is designed to facilitate smooth, shock-free stops, which contributes to reducing mechanical wear and extending the service life of both actuators and brake pads. Industry data indicates a potential 20–30% reduction in maintenance costs for systems upgraded to variable frequency control.
  • Energy Efficiency: Frequency modulation optimises motor operation, thereby reducing unnecessary power consumption during braking cycles.
