In the field of heavy equipment transportation, trackless transfer cart with a load capacity of up to 100 tons have become an increasingly popular choice for production in many enterprises. The core challenge not only lies in solving the problem of "bearing heavy loads" but also in overcoming the technical high point of "moving stably and turning flexibly". The selection of the steering system for heavy load trackless transport carts directly determines the vehicle's flexibility, stability, ground adaptability, and cost control.
Faced with such a 100 tons behemoth, traditional single-tie-rod and differential steering systems are no longer sufficient. The hydraulic multi-mode multi-wheel steering system, also known as the hydraulic suspension steering wheel omnidirectional system, is currently the most ideal and widely used solution.
Hydraulic Multi-Mode Steering System (Hydraulic Suspension Omnidirectional transfer cart)
This system uses hydraulic cylinders to synchronously push the steering mechanisms of multiple wheel sets, and an intelligent electronic control system precisely controls the stroke and synchronization of each cylinder. Its outstanding performance is reflected in the following aspects:
Super Strong Load-Bearing Capacity
The hydraulic system inherently has a powerful force amplification characteristic. It can output a thrust of hundreds of tons with a relatively small input force, easily driving the steering of giant tires and perfectly meeting the strict power requirements of 100 ton-level loads.
Flexible Switching of Multiple Modes to Cope with Complex Scenarios
Conventional four-wheel steering: Suitable for most road transportation scenarios.
Diagonal/crab steering: The transporter can move laterally, easily handling narrow passages or precise alignment.
Central rotation: The transporter can rotate with its center as the origin to achieve zero-radius rotation, greatly saving the space required for U-turns.
Semi-trailer steering: Simulates the turning mode of road semi-trailers, improving stability during long-distance high-speed driving.
This inherent flexibility is unparalleled by other steering methods.
Ground Protection and Pressure Distribution
Through the coordinated steering of multiple wheels, excessive friction and dragging between a single tire and the ground are avoided, which can effectively protect the valuable cement or epoxy floors in factory workshops, docks, and other places.
Precise Control, Stability, and Safety
The advanced electro-hydraulic servo control system ensures the precise synchronization of the steering angles of numerous wheels, eliminating tire wear and "ground gnawing" caused by the difference between inner and outer wheels. Even under heavy loads, the vehicle turns smoothly without the risk of rollover.
Comparison with Other Steering Solutions
Mechanical tie-rod steering: It has a simple structure but is only suitable for light-load and small-tonnage vehicles. For 100 tons heavy load transfer carts, it requires enormous steering force, making operation extremely difficult and failing to achieve multi-mode steering.
Electric steering wheel steering: It offers precise control, but the load-bearing capacity of a single steering wheel is limited (usually less than 30 tons). To achieve 100 ton load-bearing, multiple steering wheels need to be connected in parallel, leading to a sharp increase in cost, a complex system, and lower maintainability compared to the hydraulic system.
Manual auxiliary steering: It relies entirely on human effort and is only used for fine-tuning or emergency situations, so it cannot be used as the main steering system.
REMARKABLE is engaged in the research and development of heavy-duty omnidirectional transfer carts, with mature experience and cases. It continuously optimizes designs, innovates technologies, and improves production. For trackless flatbed trucks with a load capacity of 100 tons, the hydraulic suspension omnidirectional system is a choice that has been verified by numerous heavy engineering projects and achieves the optimal balance between performance, reliability, and economy.
