highly flexible and precise Steering behavior
Steering System by CHINA HEAVY LIFT SPMT (Electric – hydraulic Multi-Mode control)
the suspended steering system includes steering proportional valve, digital electronic steering program and modular rack and pinion steering (angle +130°/-100°)
steering modes include longitudinal and lateral all-wheel steering, diagonal, sideways, front and rear wheel steering, center slewing, and more. For the soft-joint configuration of the SPMT, the center of rotation can be freely set, ie, movement in almost any direction is allowed. Steering and changing of the steering program can be permitted while the SPMT is stationary and at full load. This allows precise lifting and transport of the largest loads
RACK-AND-PINION mechanism adopts a modular design and is connected to the frame by bolts, so it has good maintainability; at the same time, the bearing capacity is designed according to the 25-ton axle load capacity, and the rated output torque can reach 50,000N.m
Diagonal steering (transverse 90°)
Diagonal steering (transverse 90°)
RACK-AND-PINION steering mechanism of SPMT has high axle load, large steering resistance torque, and at the same time bears complex resultant forces such as axial force, radial force, overturning moment and torque, so the design calculation and reliability of the steering mechanism are very important. , We are the only one that has passed the 23-year use demonstration in the design and use of the steering mechanism. The product is mature, and the design and use experience are far ahead of other Chinese manufacturers.
ADVANTAGES: compared with other domestic manufacturers, CHINA HEAVY LIFT SPMT has the most prominent technical advantage in electric – hydraulic control technology. Through long-term international summits and technical exchanges with well-known domestic universities, combined with the actual transportation needs of the project, it took the lead in breaking through the hydraulic self-propelling in China. Technical barriers to precise alignment control of vehicles. It has world-leading controllable micro-positioning performance, micro-motion speed ≤ 2mm/s, and positioning accuracy ≤ 1mm. This model can be used for high-precision combination and alignment of module segments.
