SPMT, Self propelled Modular Transporters by CHINA HEAVY LIFT
What is SPMT? precision transportation for heavy engineering
CHINA HEAVY LIFT SPMT (Self propelled Modular Transporter) is an advanced hydraulic self-propelled transport system developed for the movement and positioning of extremely heavy, oversized and complex structures
unlike conventional trailers or fixed transportation equipment, SPMT is based on a modular design concept. each transport unit consists of multiple axle lines equipped with independent hydraulic suspension, steering systems and drive units. these modules can be combined in different configurations, including longitudinal, transverse or customized arrangements, to meet the specific requirements of different projects
through intelligent control technology, each axle line can operate independently while working together as a synchronized transport platform. this allows SPMT to adapt to various load conditions, including uneven weight distribution, complex center-of-gravity situations and restricted working environments
with multi-directional steering capability, SPMT can move forward, backward, sideways and rotate within limited spaces, providing exceptional flexibility for heavy transport and installation operations where conventional methods are not practical

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
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

Longitudinal counter steering
drive axle, hydraulic suspension 700mm (± 350 mm)
the suspension of SPMT consists of suspension frame, balance arm, suspension cylinder and axle. The axles are further divided into drive axles, brake axles and non-drive axles
a hydraulic cylinder is used to support the suspension frame and the balance arm, so that the height of SPMT platform has a lifting stroke of 700mm
drive axle is equipped with a reducer and a motor to realize the SPMT walking function
brake axle is equipped with a brake cylinder to realize the driving brake and parking brake of the SPMT
when there are pits or bumps on the road, the SPMT platform can always be kept horizontal when the vehicle is running, with good shock absorption performance; the hydraulic support system can be adjusted by the suspension hydraulic system, which can form three-point support or four-point support
axle and frame are connected by hydraulic suspension, adjustable height. axle is installed on the axle head at the front end of the swing arm. when the road surface is uneven, the suspension and the axle will lift and swing to ensure the balanced force on the axle
when the road surface is vertically uneven, longitudinal compensation can be provided by a group of lift cylinders. when the road surface is uneven laterally, the axle can be adjusted by swinging laterally

SPMT Split – separable into Two Halves for 3-file Side-by-Side configuration
SPMT SPLIT Design – maximum flexibility in transporter width
Split SPMT is designed for heavy transport applications where a conventional SPMT configuration cannot provide the optimum transporter width. the SPMT module can be split longitudinally into two independent halves, providing greater flexibility when configuring the transporter to suit different load dimensions, support points and site conditions
when a standard SPMT module is too narrow, while two modules positioned side by side are unnecessarily wide, the split design provides an effective solution. the separated half-modules can be combined with additional SPMT units to create a 3-file side-by-side configuration, achieving an intermediate transporter width while maintaining the modular advantages of the SPMT system
the increased configuration flexibility is particularly valuable when transporting ship blocks, offshore modules, petrochemical equipment, large steel structures and other oversized loads where the position of structural support points or the width of the load requires a specially adapted transporter arrangement
split configurations can also provide a wider supporting footprint for suitable loads and allow the transporter arrangement to be optimized according to the load geometry, center of gravity, ground conditions and available operating space
Unique Split SPMT manufacturing capability in China
CHINA HEAVY LIFT (HYST) is the only SPMT manufacturer in China capable of manufacturing the Split SPMT design, demonstrating our engineering and manufacturing capability in advanced modular heavy transport systems
from the precision-machined split frame structure to the hydraulic, steering and electronic control systems, the Split SPMT is engineered as an integrated modular transport solution while retaining the flexibility required for different combinations and project-specific configurations
a Split SPMT requires particularly high manufacturing accuracy, as the two longitudinal halves must operate as an integrated transporter when assembled and remain precisely compatible with other SPMT modules in different combinations. critical frame structures, connecting interfaces and key mechanical components are integrally machined on large CNC machining centers after fabrication, ensuring dimensional accuracy, precise alignment and consistent interface geometry
this high-precision manufacturing process is especially important when multiple axle lines and split modules are mechanically coupled. accurate positioning of the connecting interfaces helps maintain straightness, axle-line alignment and dimensional consistency across the complete transporter combination, reducing accumulated tolerances as the number of connected modules increases
the precision of the mechanical structure is complemented by coordinated hydraulic suspension, electronic steering and control systems. whether operated as a standard module, separated into two longitudinal halves, or recombined into wider multi-file configurations, the individual units are designed to work together as one coordinated transport system
for large and complex transporter combinations, this combination of CNC-machined structural accuracy, standardized module interfaces, synchronized steering and hydraulic load equalization provides reliable modular compatibility and makes it possible to configure the SPMT precisely according to the dimensions, support points and load distribution of each transport project
