Power Trolley Specifications

  1. High Precision Positioning: Utilizes a 1.8kw absolute value servo motor to achieve high precision positioning and repeat positioning, ensuring accurate movement of stage machinery.
  2. Strong Pulling Force: Maximum pulling force can reach 2200kg, suitable for various scenarios on hanging and ground tracks.
  3. Flexible Configuration: When moving items are overweight or oversized, it can be used in conjunction with a slave trolley or multiple power trolley to further enhance the system's load capacity.
  4. Self-Locking Function: All aerial powered carts come with a self-locking feature. If needed, users can adjust the clutch mechanism on the cart to disengage the trolley’s gears from the track rack, allowing manual movement of the cart to any position.
  5. Removable Hoist Hook: All trolley (including slave trolley) are equipped with a hoist hook underneath, compatible with CNC servo hoists. The hoist connection includes both load cell and non load cell, available as options. The hoist hook is easy to assemble and disassemble, and the bottom of the trolley is flat after removal, allowing connections with various frameworks.
  6. Clutch Mechanism on Power Trolley: Facilitates installation and positioning.
  7. Intelligent Control: Deeply integrated intelligent control system supports multi-screen coordinated control and CNC servo hoist linkage operation.
  8. Safe and Reliable: All components have a safety factor of over 2 times, with key components exceeding 3 times, ensuring the safety of equipment and personnel.
  9. Low Noise: Under standard speed and load, hanging track operation noise ≤ 55dB, ground track operation noise ≤ 65dB, providing a comfortable user environment.
  10. Electrical Box Suspension: The electrical box can be suspended on the side of the trolley for easy management and maintenance.
