KZh-1572 hydraulic railroad crane is designed for emergency and recovery works, loading and unloading operations, construction and installation on tracks with a gauge of 1520 mm.
The main units of the crane are moving and swing frames connected with each other by a rotary support with the turning angle of 360° and installed at two four-axle bogies, equipped with a hydraulic drive.
The crane’s moving frame is equipped with hydraulic outriggers having three fixed support contours (8,83х8,5 m; 7,0x12,91m and 4,4х14,47 m), automatic coupling devices and a rod-operated air brake system for crane towing or traveling as a separate unit. The crane can work both with and without outriggers.
The swing frame has the following units and devices:

  • a 3-section telescopic boom with two hydraulic lift cylinders. The boom’s operating radius is from 7,2 to 28,9 m.
  • a power plant of diesel-hydraulic power unit and a fuel tank ensuring the crane continuous operation  for 16 hours without refueling.
  • emergency unit, providing a transformation of the crane from operating to transport position in case of power plant breakdown.
  • a comfortable operator’s cab with a parameter recorder and a microprocessor-based device displaying actual and maximum load, boom radius and length and capable of automatic shutoff when rated loading capacity is exceeded and subsequent load lowering.

The crane is equipped with a telescopic balance box that helped significantly improve its performance.
All the crane equipment is covered with hoods protecting it from precipitations. For power plant starting in low temperature conditions the crane is equipped with a starting  preheater.
Crane’s traveling dimensions are in compliance with 1-Т GOST 9238-2013.
Operating temperature range is from -40°C to +40°С.
