Using your steel gantry crane with power traction drive is easy. First, make sure the crane is connected to the 460V, 3 - phase power supply. Then, use the 3 - button push - button control to move the crane to the position you need. When choosing a model, pick the GPTD - 2 if you need to lift between 2,000 and 4,000 lbs, and the GPTD - 4 for 6,000 to 8,000 lbs loads. For the V - TRACK, install it carefully on one side. As for maintenance, regularly check the power connection to ensure it's stable. Keep the control buttons clean and in good working condition. Also, check the capacity limit each time you use the crane to avoid overloading.
