Designed loading system is unique with its high lifting capacity of 110 tonnes which is 1.6 times more lifting capacity of old railway track maintenance vehicles such as PRL-4 (67 tonnes) with the same length.
Due to plain yet bold decision to allocate lifting cranes on opposite ends of two coupled platforms providing possibility for fast load of rails from any side of the track without additional actions (cranes allocated in the center of platforms on PRL-4 made choice of loading side and additional operations for bringing rails under cranes difficult).
