The price is primarily driven by the drive mechanism (manual, hydraulic, or electric) and material quality. High-end models utilize cold-rolled steel with powder coating or aluminum alloy for the frame to ensure a load capacity of at least 250kg. Essential features include X-ray translucent platforms, central braking systems, and high-density flame-retardant mattresses. Advanced units with integrated weighing scales or fifth-wheel steering systems for better maneuverability will command a premium price.
