When assessing the price of a small crawler crane (often called a spider crane), you must look beyond the sticker price at core performance metrics. Key specs include Maximum Lifting Capacity (typically 1 to 5 tons), Maximum Lifting Height, and Working Radius. Ensure the crane features a 360-degree continuous rotation and a telescopic boom with high-strength steel construction. The engine type (Diesel, Electric, or Dual Power) significantly impacts the price; Dual Power models are more expensive but offer greater versatility for indoor/outdoor use.
